Description
Cross-Reference to Related Applications
[0001] This application is a U.S. national stage application of International Application No. PCT/CN2021/077301, filed Feb. 22, 2021, the entire contents of which are incorporated herein by reference.
Technical Field
[0002] The present disclosure relates to the technical field of wireless communication, and more particularly to a method and device for determining a discontinuous reception, a communication device and a storage medium.
Background
[0003] A typical video streaming service generates video frames periodically, and a typical video frame rate is 30 frames or 60 frames per second, that is, the video frame interval is 33.33 or 16.66 milliseconds (ms). An augmented reality (AR) or a virtual reality (VR) service may provide a user with a video streaming service, and has a higher delay requirement (such as, 5 to 10 ms) than a traditional video streaming service.
[0004] In the related art, in a 5G system, in order to reduce power consumption of a user equipment (UE), a network side introduces a discontinuous reception (DRX) mechanism for uplink and downlink video services. For the DRX, a DRX cycle that may be configured by the network side includes: 10 ms, 20 ms, 32 ms, 40 ms, 60 ms, 64 ms, 70 ms, 80 ms, 128 ms, 160 ms, 256 ms, and 320 ms. However, the currently configured DRX cycle cannot match the frame interval (i.e., 33.33 ms or 16.66 ms) of the video service, so that an additional data transmission delay will be generated when the configured DRX cycle cannot match an arrival time interval of the service.

[0005] According to a first aspect of embodiments of the present disclosure, there is provided a method for determining a DRX, which is applied to a network device and includes: sending configuration information of the DRX to a UE. A specified DRX cycle value contained in the configuration information is different from any one of default configurable DRX cycle values.
[0006] According to a second aspect of embodiments of the present disclosure, there is provided a method for determining a DRX, which is applied to a UE and includes: receiving configuration information of the DRX sent by a network device, a specified DRX cycle value contained in the configuration information being different from any one of default configurable DRX cycle values; and monitoring a control channel based on the specified DRX cycle.
[0007] According to a third aspect of embodiments of the present disclosure, there is provided a communication device, which includes: a transceiver; a memory; and a processor. The processor is connected to the transceiver and the memory respectively, and configured to control a transmission and a reception of a wireless signal of the transceiver and cause the method for determining the DRX as mentioned above to be implemented by executing computer-executable instructions on the memory.
[0008] According to a fourth aspect of embodiments of the present disclosure, there is provided a computer storage medium, which has stored therein computer-executable instructions that, when executed by a processor, cause the method for determining the DRX as mentioned above to be implemented.

[0030] Aiming at the problem in the related art that an additional data transmission delay will be generated when a configured DRX cycle cannot match an arrival time interval of a service, embodiments of the present disclosure provide a method for determining a DRX.
[0031] With the method for determining the DRX provided in embodiments of the present disclosure, the network device may indicate to the UE a specified DRX cycle value that matches an arrival time interval of service data when the network device determines that the arrival time interval of any one of the service data is different from each of default configurable DRX cycle values, and perform data transmission with the UE based on the specified DRX cycle value, thereby minimizing the service data transmission delay, and improving the quality and performance of the service.
[0032] A method and device for determining a DRX, a communication device, and a storage medium provided by the present disclosure will be described in detail below with reference to the accompanying drawings.
[0033] FIG. 1 is a schematic flowchart of a method for determining a DRX provided by embodiments of the present disclosure, which is applied to a network device, such as a base station.
[0034] As shown in FIG. 1 , the method for determining the DRX includes following steps.
[0035] In step 101, configuration information of the DRX is sent to a UE. A specified DRX cycle value contained in the configuration information is different from any one of default configurable DRX cycle values.
[0036] Optionally, the specified DRX cycle value may be determined by the network device according to a protocol, or may be determined according to requirements of a current service.
[0037] In addition, the above-described configuration information may be a radio resource control (RRC) message or a physical downlink control channel (PDCCH) control signaling, which is not limited in the present disclosure.
[0038] The specified DRX cycle value may be a value of any one of following types of DRX cycles: a DRX long cycle, a DRX short cycle, a scheduling period, a retransmission period, a hybrid automatic repeat request (HARD) period and an inactivity period.
[0039] It can be understood that for different types of DRX cycles, the default configurable DRX cycle values are different. For example, for the DRX long cycle, the default configurable DRX cycle values may include: 10 ms, 20 ms, 32 ms, 40 ms, 60 ms, 64 ms, 70 ms, 80 ms, 128 ms, 160 ms, 256 ms, 320 ms. For the DRX short cycle, the default configurable DRX cycle values may include: 2 ms, 3 ms, 4 ms, 5 ms, 6 ms, 7 ms, 8 ms, 10 ms, 14 ms, 16 ms, 20 ms, 30 ms, 32 ms, 35 ms, 40 ms, 64 ms, 80 ms, 128 ms, 160 ms, 256 ms, 320 ms, 512 ms, 640 ms.
[0040] Optionally, in the present disclosure, when determining that an arrival time interval of any one of service data is different from each of the default configurable DRX cycle values, the network device may determine the specified DRX cycle value according to the arrival time interval of the any one of the service data.
[0041] For example, AR or VR services can provide users with video streaming services. The typical video frame rate is 30 frames or 60 frames per second, that is, an arrival time interval of video frames is 33.33 ms or 16.66 ms, which however is different from the default configurable DRX cycle values (such as 10 ms, 20 ms, etc.). Therefore, the network device in the present disclosure is able to determine a current specified DRX cycle value according to the arrival time interval of the video service, and send the specified DRX cycle value to the UE, so as to perform uplink and downlink data transmissions with the UE based on the specified DRX cycle value.
[0042] Optionally, the specified DRX cycle value may include different content as required. For example, the specified DRX cycle value may include a first DRX cycle value, and the first DRX cycle value may be a millisecond value, the number of sub-milliseconds, or the number of orthogonal frequency division multiplexing (OFDM) symbols.
[0043] The term “sub-millisecond” is a new time measuring unit proposed in the present disclosure to more accurately represent the specified DRX cycle value, so that the specified DRX cycle value is as close as possible to the arrival time interval of the service data. It should be noted that a sub-millisecond may be a time measuring unit smaller than a millisecond, and a specific duration corresponding to a sub-millisecond may be determined as required, which is not limited in embodiments of the present disclosure.
[0044] Optionally, the specified DRX cycle value may also include a combination of a first DRX cycle value and a second DRX cycle value. The first DRX cycle value may be a millisecond value or the number of symbols, and the second DRX cycle value may also be a millisecond value, the number of symbols, or the number of sub-milliseconds, etc., which are not limited in the present disclosure.
[0045] Optionally, the specified DRX cycle value may also include a combination of a first DRX cycle value, a second DRX cycle value, and a third DRX cycle value. The first DRX cycle value may be a millisecond value, the second DRX cycle value may also be a millisecond value, and the third DRX cycle value may be the number of symbols or the number of sub-milliseconds, etc., which are not limited in the present disclosure.
[0046] In order to support wider application scenarios, several types of subcarrier spacing (SCS) may be configured in a wireless communication system. As shown in Table 1 below, different SCSs and cyclic prefixes (CP) correspond to different resource allocation information:
[0047]
| TABLE 1 | |||||
|---|---|---|---|---|---|
| Number of | Duration per | Number of | Duration per | Number of slots | |
| SCS (kHz) | symbols per slot | symbol (ms) | slots per frame | slot (ms) | per sub-frame |
| 15 | 14 | 0.0714 | 10 | 1 | 1 |
| 30 | 14 | 0.0357 | 20 | 0.5 | 2 |
| 60 (normal CP) | 14 | 0.0179 | 40 | 0.25 | 4 |
| 60 (extended CP) | 12 | 0.0208 | 40 | 0.25 | 4 |
| 120 | 14 | 0.0089 | 80 | 0.125 | 8 |
| 240 | 14 | 0.0045 | 160 | 0.0625 | 16 |
[0048] It can be understood that each element or each correspondence in Table 1 exist independently. Even though these elements and correspondences are listed in the same table, it does not mean that all the elements and correspondences in Table 1 must exist at the same time as shown in Table 1, and the value of each element and each correspondence do not depend on the value of any other element or any other correspondence in Table 1. Therefore, those skilled in the art can understand that the value of each element and each correspondence in Table 1 correspond to an independent embodiment.
[0049] As a possible implementation, when determining the specified DRX cycle value, the network device can determine the specified DRX cycle value in each SCS, i.e., determine the number of symbols, a millisecond value, and/or the number of sub-milliseconds included in the specified DRX cycle value in each SCS, according to the resource allocation information corresponding to different SCSs.
[0050] As another possible implementation, when determining the specified DRX cycle value, the network device may also determine the specified DRX cycle value in each SCS based on the specified DRX cycle value in a specified SCS. Specifically, the network device may determine the specified DRX cycle value in the specified SCS according to the resource allocation information corresponding to the specified SCS, and determine the specified DRX cycle value in any other SCS according to a relationship between the resource allocation information corresponding to the specified SCS and the resource allocation information corresponding to the any other SCS, and the specified DRX cycle value in the specified SCS.
[0051] With the method for determining the DRX according to embodiments of the present disclosure, by setting a specified DRX cycle value for the DRX, data transmission is performed with the UE based on the DRX cycle value that matches the arrival time interval of data of the service to be performed as much as possible, thereby minimizing service data transmission delay and improving the quality and performance of the service.
[0052] Below, a method for determining a DRX provided by embodiments of the present disclosure will be further described with reference to FIG. 2 .
[0053] FIG. 2 is a schematic flowchart of a method for determining a DRX provided by embodiments of the present disclosure, which is applied to a network device, such as a base station.
[0054] As shown in FIG. 2 , the method for determining the DRX includes the following steps.
[0055] In step 201, in response to an arrival time interval of any one of service data being different from any one of the default configurable DRX cycle values, any one of the default configurable DRX cycle values that is less than the arrival time interval of the any one of the service data is determined as a millisecond value m corresponding to a first DRX cycle value included in the specified DRX cycle value, where the m is a positive integer.
[0056] As a possible implementation, when the specified DRX cycle value is a combination of a first DRX cycle value and a second DRX cycle value, the first DRX cycle value and the second DRX cycle value each may be a millisecond value.
[0057] Optionally, when determining the first DRX cycle value, if there are a plurality of default configurable DRX cycle values that are all less than the arrival time interval of any one of the service data, any default configurable DRX cycle value selected from the a plurality of default configurable DRX cycle values may be used as the first DRX cycle value; alternatively, a default configurable DRX cycle value with a smallest difference from the arrival time interval of any one of the service data may be selected as the first DRX cycle value.
[0058] For example, the arrival time interval of any one of the service data is 16.66 ms, for the DRX long cycle, when determining the specified DRX cycle value in each SCS, since the default configurable DRX cycle value less than 16.66 ms is 10 ms, the first DRX cycle value may be determined as 10 ms.
[0059] For another example, the arrival time interval of any one of the service data is 33.33 ms, for the DRX long cycle, when determining the specified DRX cycle value in each SCS, since the default configurable DRX cycle values less than 33.33 ms are 10 ms, 20 ms and 32 ms, the first DRX cycle value may be determined to be 10 ms, 20 ms or 32 ms. Alternatively, since the difference between 32 ms and 33.33 ms is the smallest, the first DRX cycle value may be determined as 32 ms.
[0060] In step 202, a first difference value between the arrival time interval of the any one of the service data and the m is determined as a millisecond value corresponding to a second DRX cycle value included in the specified DRX cycle value.
[0061] Optionally, when the specified DRX cycle value is a combination of the first DRX cycle value and the second DRX cycle value, and the first DRX cycle value and the second DRX cycle value each may be a millisecond value, the first difference value between the arrival time interval of the any one of the service data and the m may be determined as the millisecond value corresponding to the second DRX cycle value.
[0062] For example, the arrival time interval of the service data is 16.66 ms, for the DRX long cycle, the first DRX cycle value included in the specified DRX cycle value is 10 ms, and the first difference value is 6.66 ms. In this case, the second DRX cycle value included in the specified DRX cycle value in each SCS may be determined as 6.66 ms.
[0063] For another example, the arrival time interval of the service data is 33.33 ms, for the DRX long cycle, the first DRX cycle value included in the specified DRX cycle value is 32 ms, and the first difference value is 1.33 ms. In this case, the second DRX cycle value included in the specified DRX cycle value in each SCS may be determined as 1.33 ms.
[0064] In step 203, configuration information of the DRX is sent to a user equipment. A specified DRX cycle value contained in the configuration information is different from any one of default configurable DRX cycle values.
[0065] In embodiments of the present disclosure, the step 203 may be implemented in any manner as described in various embodiments of the present disclosure, which is not limited in embodiments of the present disclosure, and will not be elaborated here.
[0066] With the method for determining the DRX provided in embodiments of the present disclosure, the network device may indicate to the UE a specified DRX cycle value that matches an arrival time interval of service data when the network device determines that the arrival time interval of any one of the service data is different from each of default configurable DRX cycle values, and perform data transmission with the UE based on the specified DRX cycle value, thereby minimizing the service data transmission delay, and improving the quality and performance of the service.
[0067] Below, a method for determining a DRX provided by embodiments of the present disclosure will be further described with reference to FIG. 3 .
[0068] FIG. 3 is a schematic flowchart of a method for determining a DRX provided by embodiments of the present disclosure, which is applied to a network device.
[0069] As shown in FIG. 3 , the method for determining the DRX includes the following steps.
[0070] In step 301, in response to an arrival time interval of any one of service data being different from any one of the default configurable DRX cycle values, a duration corresponding to any one of the default configurable DRX cycle values that is less than the arrival time interval of the any one of the service data is determined as a millisecond value m corresponding to a first DRX cycle value included in the specified DRX cycle value.
[0071] In step 302, a first difference value between the arrival time interval of the any one of the service data and the m is determined.
[0072] In embodiments of the present disclosure, the steps 301-302 may be implemented in any manner as described in various embodiments of the present disclosure, which are not limited in embodiments of the present disclosure, and will not be elaborated here.
[0073] In step 303, a quotient of the first difference value and a specified reference coefficient is determined as the number of sub-milliseconds corresponding to a second DRX cycle value included in the specified DRX cycle value.
[0074] The specified reference coefficient may be 1/a. It should be noted that, the specific value of a may be determined as required, which is not limited in embodiments of the present disclosure. For example, a may be 32, so the specified reference coefficient is 1/32.
[0075] As a possible implementation, when the specified DRX cycle value is a combination of the first DRX cycle value and the second DRX cycle value, the first DRX cycle value may be a millisecond value, and the second DRX cycle value may be the number of sub-milliseconds. Therefore, the quotient of the first difference value between the arrival time interval of the any one of the service data and the m and the specified reference coefficient may be determined as the number of sub-milliseconds corresponding to the second DRX cycle value.
[0076] For example, the arrival time interval of the service data is 16.66 ms, and the specified reference coefficient is 1/32. For the DRX long cycle, the first DRX cycle value included in the specified DRX cycle value in each SCS is 10 ms, and the first difference value is 6.66 ms. In this case, the number of sub-milliseconds corresponding to the second DRX cycle value included in the specified DRX cycle value in each SCS may be determined to be 6.66/( 1/32)=213.
[0077] For another example, the arrival time interval of the service data is 33.33 ms, and the specified reference coefficient is 1/32. For the DRX long cycle, the first DRX cycle value included in the specified DRX cycle value in each SCS is 32 ms, and the first difference value is 1.33 ms. In this case, the number of sub-milliseconds corresponding to the second DRX cycle value included in the specified DRX cycle value in each SCS may be determined to be 1.33/( 1/32)=43.
[0078] Optionally, when the quotient of the first difference value and the specified reference coefficient is not an integer, a rounded value of the quotient of the first difference value and the specified reference coefficient may be determined as the number of sub-milliseconds corresponding to the second DRX cycle value included in the specified DRX cycle value. In embodiments of the present disclosure, the rounding may be rounding down, rounding up, or rounding off, and so on.
[0079] In step 304, configuration information of the DRX is sent to a user equipment. A specified DRX cycle value contained in the configuration information is different from any one of default configurable DRX cycle values.
[0080] In embodiments of the present disclosure, the step 304 may be implemented in any manner as described in various embodiments of the present disclosure, which is not limited in embodiments of the present disclosure, and will not be elaborated here.
[0081] With the method for determining the DRX provided in embodiments of the present disclosure, the network device may indicate to the UE a specified DRX cycle value that matches an arrival time interval of service data when the network device determines that the arrival time interval of any one of the service data is different from each of default configurable DRX cycle values, and perform data transmission with the UE based on the specified DRX cycle value, thereby minimizing the service data transmission delay, and improving the quality and performance of the service.
[0082] Below, a method for determining a DRX provided by embodiments of the present disclosure will be further described with reference to FIG. 4 .
[0083] FIG. 4 is a schematic flowchart of a method for determining a DRX provided by embodiments of the present disclosure, which is applied to a network device.
[0084] As shown in FIG. 4 , the method for determining the DRX includes the following steps.
[0085] In step 401, in response to an arrival time interval of any one of service data being different from any one of the default configurable DRX cycle values, a duration corresponding to any one of the default configurable DRX cycle values that is less than the arrival time interval of the any one of the service data is determined as a millisecond value m corresponding to a first DRX cycle value included in the specified DRX cycle value in each SCS, where m is a positive integer.
[0086] Time domain resource allocation information of each SCS may include: a duration per slot and a duration per symbol.
[0087] As a possible implementation, when the specified DRX cycle value is a combination of the first DRX cycle value and the second DRX cycle value, the first DRX cycle value may be a millisecond value, and the second DRX cycle value may be the number of symbols.
[0088] Optionally, when determining the first DRX cycle value, if there are a plurality of default configurable resource DRX cycles that are all less than the arrival time interval of any one of the service data, any of the a plurality of default configurable resource DRX cycles may be selected; alternatively, a default configurable resource DRX cycle with a smallest difference from the arrival time interval of any one of the service data may be selected from the a plurality of default configurable resource DRX cycles.
[0089] For example, the arrival time interval of any one of the service data is 16.66 ms, for a SCS of 15 kHZ, when determining the specified DRX cycle value corresponding to the SCS, since the default configurable DRX cycle value less than 16.66 ms is 10 ms, the first DRX cycle value may be determined as 10 ms.
[0090] For another example, the arrival time interval of any one of the service data is 33.33 ms, for a SCS of 15 kHZ, when determining the specified DRX cycle value corresponding to the SCS, since the default configurable DRX cycle values less than 33.33 ms are 10 ms, 20 ms and 32 ms, the first DRX cycle value may be determined to be 10 ms, 20 ms or 32 ms. Alternatively, since the difference between 32 ms and 33.33 ms is the smallest, the first DRX cycle value may be determined as 32 ms.
[0091] In step 402, a first difference value between the arrival time interval of the any one of the service data and the m is determined.
[0092] In step 403, the number of symbols corresponding to a second DRX cycle value included in the specified DRX cycle value in each SCS is determined according to the first difference value and the duration per symbol.
[0093] Optionally, a rounded value of a quotient of the first difference value and the duration per symbol in each SCS may be determined as the number of symbols corresponding to the second DRX cycle value included in the specified DRX cycle value in each SCS.
[0094] In embodiments of the present disclosure, the rounding may be rounding down, rounding up, or rounding off, and so on.
[0095] For example, the arrival time interval of the service data is 16.66 ms, and the first DRX cycle value included in the specified DRX cycle value is 10 ms for a SCS of 15 kHZ. In this case, the first difference value is 6.66 ms, and a quotient of the first difference value and a duration per symbol (0.0714 ms) corresponding to the SCS of 15 kHZ is 93.277, which is rounded off to a value of 93. Therefore, the number of symbols corresponding to the second DRX cycle value included in the specified DRX cycle value corresponding to the SCS of 15 kHZ is 93.
[0096] For another example, the arrival time interval of the service data is 16.66 ms, and the first DRX cycle value included in a specified resource is 10 ms for a SCS of 30 kHZ. In this case, the first difference value is 6.66 ms, and a quotient of the first difference value and a duration per symbol (0.0357 ms) corresponding to the SCS of 30 kHZ is 186.555, which is rounded off to a value of 187. Therefore, the number of symbols corresponding to the second DRX cycle value included in the specified DRX cycle value corresponding to the SCS of 30 kHZ is 187.
[0097] For a service with the data arrival time interval of 16.66 ms (the first DRX cycle value is 10 ms) or 33.33 ms (the first DRX cycle value is 32 ms), a rounded value of a quotient of the first difference value and the duration per symbol in each SCS may be determined as a value configurable for the second DRX cycle value included in the specified DRX cycle value in each SCS, as shown in Table 2 below:
[0098]
| TABLE 2 | ||
|---|---|---|
| second DRX cycle value | second DRX cycle value | |
| (corresponding to a | (corresponding to a | |
| service with an | service with an | |
| arrival time interval | arrival time interval | |
| SCS (kHz) | of 16.66 ms) | of 33.33 ms) |
| 15 | 93 | 19 |
| 30 | 187 | 37 |
| 60 (normal CP) | 372 | 74 |
| 60 (extended CP) | 320 | 64 |
| 120 | 748 | 150 |

[0099] It can be understood that each element or each correspondence in Table 2 exist independently. Even though these elements and correspondences are listed in the same table, it does not mean that all the elements and correspondences in Table 2 must exist at the same time as shown in Table 2, and the value of each element and each correspondence do not depend on the value of any other element or any other correspondence in Table 2. Therefore, those skilled in the art can understand that the value of each element and each correspondence in Table 2 correspond to an independent embodiment.
[0100] It should be noted that, the quotient of the first difference value and the duration per symbol in each SCS may be rounded up or rounded down, and the rounded value may be determined as the above individual value of the second DRX cycle value included in the specified DRX cycle value.
[0101] Optionally, as can be seen from Table 1, there exists a certain multiple relationship among various SCSs in term of the duration per symbol and the duration per slot. In the present disclosure, it is also possible to determine any SCS as a specified SCS, so that after the specified DRX cycle value in the specified SCS is determined, the specified DRX cycle value in each SCS may be determined based on the specified DRX cycle value in the specified SCS.
[0102] That is, in the present disclosure, a product of a rounded value of a quotient of the first difference value and the duration per symbol in the specified SCS multiplied by a ratio of the number of slots per frame in each SCS to the number of slots per frame in the specified SCS may be determined as the number of symbols corresponding to the second DRX cycle value included in the specified DRX cycle value in each SCS.
[0103] For example, for a service with an arrival time interval of 16.66 ms, as can be seen from the above analysis, for a SCS of 15 kHZ (the number of slots per frame is 10), the number of symbols corresponding to the second DRX cycle value is 93. If the SCS of 15 kHZ is the specified SCS, the number of symbols corresponding to the second DRX cycle value included in the designated DRX cycle value in a SCS of 30 kHZ (the number of slots per frame is 20) is: 93×(20/10)=186.
[0104] In addition, for the extended CP, as compared with the normal CP, when the duration per slot is the same, the number of symbols per slot is different. Therefore, the specified DRX cycle value in the extended CP may be calculated using any method of calculating the specified DRX cycle value as described in the present disclosure.
[0105] For example, if the SCS of 15 kHZ is the specified SCS, in the case where it is determined for the service with the arrival time interval of 16.66 ms that the first DRX cycle value in the specified DRX cycle value in the SCS of 15 kHZ is 10 ms, and the second DRX cycle value is 93 symbols, it may be determined that the first DRX cycle value in the specified DRX cycle value in the SCS of 30 kHZ is 10 ms, and the second DRX cycle value is 93×2=186, where 2 is the ratio of the number of slots per frame in the SCS of 30 kHZ to the number of slots per frame in the SCS of 15 kHZ. Similarly, the specified DRX cycle value in each SCS can be determined.
[0106] For a service with the data arrival time interval of 16.66 ms (the first DRX cycle value is 10 ms, and the second DRX cycle value is 6 ms) or 33.33 ms (the first DRX cycle value is 32 ms, and the second DRX cycle value is 1 ms), in the case where the SCS of 15 kHZ is the specified SCS, the value configurable for the second DRX cycle value in the specified DRX cycle value in each SCS may be determined according to the relationship among different SCSs in term of the number of slots per frame, as shown in Table 3 below.

[0108] It can be understood that each element or each correspondence in Table 3 exist independently. Even though these elements and correspondences are listed in the same table, it does not mean that all the elements and correspondences in Table 3 must exist at the same time as shown in Table 3, and the value of each element and each correspondence do not depend on the value of any other element or any other correspondence in Table 3. Therefore, those skilled in the art can understand that the value of each element and each correspondence in Table 3 correspond to an independent embodiment.
[0109] Optionally, a maximum integer multiple of a first specified value contained in a quotient of the first difference value and the duration per symbol may be determined as the number of symbols corresponding to the second DRX cycle included in the specified DRX cycle value in each SCS.
[0110] The first specified value may be a value agreed in a protocol or a value configured by a network. For example, the first specified value may be 2, 5, or 10, etc., which is not limited in the present disclosure.
[0111] For example, the first specified value is 5, and the arrival time interval of service data is 16.66 ms. For a SCS of 15 kHZ, the first DRX cycle value included in the specified DRX cycle value is 10 ms, and the first difference value is 6.66 ms. The quotient of the first difference value and the duration per symbol (0.0714 ms) corresponding to the SCS of 15 kHZ is 93.277, so 90 (the maximum integer multiple of 5) may be determined as the number of symbols corresponding to the second DRX cycle value included in the specified DRX cycle value in the SCS of 15 kHZ.
[0112] For another example, the arrival time interval of service data is 16.66 ms. For a SCS of 30 kHZ, the first DRX cycle value included in the specified resource is 10 ms, and the first difference value is 6.66 ms. The quotient of the first difference value and the duration per symbol (0.0357 ms) corresponding to the SCS of 30 kHZ is 186.555, so 185 (the maximum integer multiple of 5) may be determined as the number of symbols corresponding to the second DRX cycle value included in the specified DRX cycle value in the SCS of 30 kHZ.
[0113] It should be noted that when calculating the specified DRX cycle value in each SCS, the method as describe in any embodiment of the present disclosure may be used as required, which is not limited in the present disclosure.
[0114] In step 404, configuration information of the DRX is sent to a user equipment. A specified DRX cycle value contained in the configuration information is different from any one of default configurable DRX cycle values.
[0115] The configuration information of the DRX may further include cell information and/or bandwidth part (BWP) information corresponding to the number of symbols in the specified DRX cycle value. The cell information may include at least one of: a cell group identifier, a cell identifier and a cell type. The BWP information may include at least one of: a BWP identifier and a BWP type.
[0116] In embodiments of the present disclosure, since different cells or BWPs may correspond to different symbol durations, when the specified DRX cycle value includes the number of symbols, the configuration information of the DRX may also include the cell information and/or the BWP information, so that the UE can determine a current duration per symbol according to the cell information and/or the BWP information in the configuration information of the DRX, so as to accurately determine the number of symbols included in the specified DRX cycle value.
[0117] In embodiments of the present disclosure, the step 404 may be implemented in any manner as described in various embodiments of the present disclosure, which is not limited in embodiments of the present disclosure, and will not be elaborated here.
[0118] With the method for determining the DRX provided in embodiments of the present disclosure, the network device may indicate to the UE a specified DRX cycle value that matches an arrival time interval of service data when the network device determines that the arrival time interval of any one of the service data is different from each of default configurable DRX cycle values, and perform data transmission with the UE based on the specified DRX cycle value, thereby minimizing the service data transmission delay, and improving the quality and performance of the service.
[0119] Below, a method for determining a DRX provided by embodiments of the present disclosure will be further described with reference to FIG. 5 .
[0120] FIG. 5 is a schematic flowchart of a method for determining a DRX provided by embodiments of the present disclosure, which is applied to a network device.
[0121] As shown in FIG. 5 , the method for determining the DRX includes the following steps.
[0122] In step 501, in response to an arrival time interval of any one of service data being different from any one of the default configurable DRX cycle values, a millisecond value m corresponding to a first DRX cycle value included in the specified DRX cycle value in each SCS is determined according to a quotient S of the arrival time interval of the any one of the service data and the duration per slot corresponding to a specified SCS, where m is a positive integer.
[0123] The time domain resource allocation information of each SCS may include: a duration per slot and a duration per symbol.
[0124] Optionally, the millisecond value m corresponding to the first DRX cycle value may be determined according to the size of the quotient S or the relationship with each default configurable DRX cycle value.
[0125] For example, an integer part of the S may be determined as the millisecond value m corresponding to the first DRX cycle value included in the specified DRX cycle value in each SCS.
[0126] For example, the arrival time interval of any one of service data is 16.66 ms, a SCS of 15 kHZ is the specified SCS, that is, the duration per slot corresponding to the specified SCS is 1 ms, and the quotient S is 16.66. In this case, 16 may be determined as the millisecond value m corresponding to the first DRX cycle value included in the specified DRX cycle value in each SCS.
[0127] Alternatively, a maximum multiple value of a second specified value contained in the S may be determined as the millisecond value m corresponding to the first DRX cycle value included in the specified DRX cycle value in each SCS.
[0128] The second specified value may be a value agreed in a protocol or a value configured by a network. For example, the second specified value may be 2, 5, or 10, etc., which is not limited in the present disclosure.
[0129] For example, the second specified value is 5. For a service with the arrival time interval of the service data of 16.66 ms, a SCS of 15 kHZ is the specified SCS, that is, the duration per slot corresponding to the specified SCS is 1 ms, and the quotient S is 16.66. In this case, 15 (the maximum multiple of 5) may be determined as the millisecond value m corresponding to the first DRX cycle value included in the specified DRX cycle value in each SCS.
[0130] Alternatively, a default configurable DRX cycle value smaller than the S may be determined as the millisecond value m corresponding to the first DRX cycle value included in the specified DRX cycle value in each SCS.
[0131] Optionally, when determining the first DRX cycle value, if there are a plurality of default configurable DRX cycle values that are all less than 5, any default configurable DRX cycle value selected from the a plurality of default configurable DRX cycle values may be determined as the millisecond value m corresponding to the first DRX cycle value. Alternatively, a default configurable DRX cycle value with the smallest difference from S may be selected as the millisecond value m corresponding to the first DRX cycle value.
[0132] For example, the arrival time interval of any one of the service data is 16.66 ms, a SCS of 15 kHZ is the specified SCS, that is, the duration per slot corresponding to the specified SCS is 1 ms, and the quotient S is 16.66. Since the default configurable DRX cycle value less than S (16.66) is 10 ms, the millisecond value m corresponding to the first DRX cycle value may be determined as 10 ms.
[0133] For another example, the arrival time interval of any one of the service data is 33.33 ms, a SCS of 15 kHZ is the specified SCS, that is, the duration per slot corresponding to the specified SCS is 1 ms, and the quotient S is 33.33. Since the default configurable DRX cycle values less than S (33.33) are 10 ms, 20 ms and 32 ms, and the difference between 32 ms and 33.33 is the smallest, the millisecond value m corresponding to the first DRX cycle value may be determined as 32 ms.
[0134] In step 502, a second difference value between the arrival time interval of the any one of the service data and the m is determined.
[0135] In step 503, the number of symbols corresponding to a second DRX cycle value included in the specified DRX cycle value in each SCS is determined according to the second difference value and the duration per symbol.
[0136] In embodiments of the present disclosure, for a specific manner for determining the number of symbols corresponding to the second DRX cycle value included in the specified DRX cycle value in each SCS according to the second difference value and the duration per symbol corresponding to each SCS, reference may be made to the detailed descriptions of any other embodiment, which will not be elaborated here.
[0137] In step 504, configuration information of the DRX is sent to a user equipment. A specified DRX cycle value contained in the configuration information is different from any one of default configurable DRX cycle values.
[0138] In embodiments of the present disclosure, the step 504 may be implemented in any manner as described in various embodiments of the present disclosure, which is not limited in embodiments of the present disclosure, and will not be elaborated here.
[0139] With the method for determining the DRX provided in embodiments of the present disclosure, the network device may indicate to the UE a specified DRX cycle value that matches an arrival time interval of service data when the network device determines that the arrival time interval of any one of the service data is different from each of default configurable DRX cycle values, and perform data transmission with the UE based on the specified DRX cycle value, thereby minimizing the service data transmission delay, and improving the quality and performance of the service.
[0140] Below, a method for determining a DRX provided by embodiments of the present disclosure will be further described with reference to FIG. 6 .
[0141] FIG. 6 is a schematic flowchart of a method for determining a DRX provided by embodiments of the present disclosure, which is applied to a network device.
[0142] As shown in FIG. 6 , the method for determining the DRX includes the following steps.
[0143] In step 601, in response to an arrival time interval of any one of service data being different from any one of the default configurable DRX cycle values, any one of the default configurable DRX cycle values that is less than the arrival time interval of the any one of the service data is determined as a millisecond value m corresponding to a first DRX cycle value included in the specified DRX cycle value in each SCS.
[0144] In this embodiment, for the specific process of determining the first DRX cycle value included in the specified DRX cycle value in each SCS, reference may be made to the detailed descriptions of any other embodiment, which will not be elaborated here.
[0145] The m is a positive integer.
[0146] In step 602, a first difference value between the arrival time interval of the any one of the service data and the m is determined.
[0147] In step 603, a rounded value of a quotient of the first difference value and the duration per slot corresponding to a specified SCS is determined as a millisecond value k corresponding to a second DRX cycle value included in the specified DRX cycle value in each SCS, where the k is a positive integer.
[0148] As a possible implementation, the specified DRX cycle value may be a combination of a first DRX cycle value, a second DRX cycle value and a third DRX cycle value, and the first DRX cycle value and the second DRX cycle value each may be a millisecond value, and the third DRX cycle value may be the number of symbols.
[0149] Optionally, the quotient of the first difference value and the duration per slot corresponding to the specified SCS may be rounded down, and the rounded value may be determined as the millisecond value k corresponding to the second DRX cycle value included in the specified DRX cycle value in each SCS.
[0150] For example, for a service with the arrival time interval of service data of 16.66 ms, the specified SCS is a SCS of 15 kHZ (the duration per slot is 1 ms), the millisecond value m corresponding to the first DRX cycle value included in the specified DRX cycle value is 10, the first difference value is 6.66 ms, and the quotient of the first difference value (6.66 ms) and the duration (1 ms) per slot is 6.66. In this case, the millisecond value corresponding to the second DRX cycle value included in the specified DRX cycle value in each SCS may be determined as 6.
[0151] Similarly, for a service with the arrival time interval of service data of 33.33 ms, the specified SCS is a SCS of 15 kHZ (the duration per slot is 1 ms), the millisecond value m corresponding to the first DRX cycle value included in the specified DRX cycle value is 32, the first difference value is 1.33 ms, and the quotient of the first difference value (1.33 ms) and the duration (1 ms) per slot is 1.33. In this case, the millisecond value corresponding to the second DRX cycle value included in the specified DRX cycle value in each SCS may be determined as 1.
[0152] In step 604, a third difference value between the first difference value and the k is determined.
[0153] In step 605, the number of symbols corresponding to a third DRX cycle value included in the specified DRX cycle value in each SCS is determined according to the third difference value and the duration per symbol.
[0154] Optionally, a rounded value of a quotient of the third difference value and the duration per symbol corresponding to each SCS may be determined as the number of symbols corresponding to the third DRX cycle value included in the specified DRX cycle value in each SCS.
[0155] The number of symbols corresponding to the third DRX cycle value included in the specified DRX cycle value in each SCS may be determined by means of rounding down, rounding up, or rounding off, and so on.
[0156] For example, the arrival time interval of service data is 16.66 ms, for a SCS of 15 kHZ, the first DRX cycle value included in the specified DRX cycle value is 10 ms, and the second DRX cycle value is 6 ms, so the third difference value is 0.66 ms, and the quotient of the third difference value and the duration (0.0714 ms) per symbol corresponding to the SCS of 15 kHZ is 9.243, which is rounded up to a value of 10. In this case, the number of symbols corresponding to the third DRX cycle value included in the specified DRX cycle value corresponding to the SCS of 15 kHZ is 10.
[0157] For another example, the arrival time interval of service data is 16.66 ms, for a SCS of 30 kHZ, the first DRX cycle value included in the specified DRX cycle value is 10 ms, and the second DRX cycle value is 6 ms, so the third difference value is 0.66 ms, and the quotient of the third difference value and the duration (0.0357 ms) per symbol corresponding to the SCS of 30 kHZ is 18.49, which is rounded up to a value of 19. In this case, the number of symbols corresponding to the third DRX cycle value included in the specified DRX cycle value corresponding to the SCS of 30 kHZ is 19.
[0158] For a service with a data arrival time interval of 16.66 ms (the first DRX cycle value is 10 ms, and the second DRX cycle value is 6 ms) or 33.33 ms (the first DRX cycle value is 32 ms, and the second DRX cycle value is 1 ms), a rounded value of a quotient of the third difference value and the duration per symbol in each SCS may be determined as a configurable value of the third DRX cycle value included in the specified DRX cycle value in each SCS, as shown in Table 4 below.
[0159]
| TABLE 4 | ||

| third DRX cycle value | third DRX cycle value | |
| (corresponding to a | (corresponding to a | |

[0160] It can be understood that each element or each correspondence in Table 4 exist independently. Even though these elements and correspondences are listed in the same table, it does not mean that all the elements and correspondences in Table 4 must exist at the same time as shown in Table 4, and the value of each element and each correspondence do not depend on the value of any other element or any other correspondence in Table 4. Therefore, those skilled in the art can understand that the value of each element and each correspondence in Table 4 correspond to an independent embodiment.
[0161] It should be noted that, the quotient of the third difference value and the duration per symbol in each SCS may be rounded up or rounded down, and the rounded value may be determined as the number of symbols corresponding to the third DRX cycle value included in the specified DRX cycle value in each SCS, which is not limited in the present disclosure.
[0162] Optionally, as can be seen from Table 1, there exists a certain multiple relationship among various SCSs in term of the duration per symbol and the duration per slot. In the present disclosure, it is also possible to determine any SCS as a specified SCS, so that after the specified DRX cycle value in the specified SCS is determined, the specified DRX cycle value in each SCS may be determined based on the specified DRX cycle value in the specified SCS.
[0163] That is, in the present disclosure, it is also possible to determine a product of a rounded value of a quotient of the third difference value and the duration per symbol corresponding to the specified SCS multiplied by a ratio of the number of slots per frame in each SCS to the number of slots per frame in the specified SCS as the number of symbols corresponding to the third DRX cycle value included in the specified DRX cycle value in each SCS.
[0164] In addition, for the extended CP, as compared with the normal CP, when the duration per slot is the same, the number of symbols per slot is different. Therefore, the specified DRX cycle value in the extended CP may be calculated using any method of calculating the specified DRX cycle value as described in the present disclosure.
[0165] For example, if a SCS of 15 kHZ (the number of slots per frame is 10) is the specified SCS, in the case where it is determined for a service with the data arrival time interval of 16.66 ms that the first DRX cycle value in the specified DRX cycle value in the SCS of 15 kHZ is 10 ms, the second DRX cycle value is 6 ms, and the third DRX cycle value is 10 symbols (obtained by rounding the value of 9.243 up), it may be determined that the first DRX cycle value in the specified DRX cycle value in the SCS of 30 kHZ (the number of slots per frame is 20) is 10 ms, the second DRX cycle value is 6 ms, and the third DRX cycle value is 10×2=20, where 2 is the ratio of the number of slots per frame in the SCS of 30 kHZ to the number of slots per frame in the SCS of 15 kHZ. Similarly, the specified DRX cycle value in each SCS can be determined.
[0166] For a service with the data arrival time interval of 16.66 ms (the first DRX cycle value is 10 ms, and the second DRX cycle value is 6 ms) or 33.33 ms (the first DRX cycle value is 32 ms, and the second DRX cycle value is 1 ms), in the case where the SCS of 15 kHZ is the specified SCS, the value configurable for the third DRX cycle value in the specified DRX cycle value in each SCS may be determined according to the relationship among different SCSs in term of the number of slots per frame, as shown in Table 5 below.

[0168] It can be understood that each element or each correspondence in Table 5 exist independently. Even though these elements and correspondences are listed in the same table, it does not mean that all the elements and correspondences in Table 5 must exist at the same time as shown in Table 5, and the value of each element and each correspondence do not depend on the value of any other element or any other correspondence in Table 5. Therefore, those skilled in the art can understand that the value of each element and each correspondence in Table 5 correspond to an independent embodiment.
[0169] It should be noted that, the specified DRX cycle value in each SCS may be calculated using the method as described in any embodiment of the present disclosure as required, which is not limited in the present disclosure.
[0170] In step 606, configuration information of the DRX is sent to a user equipment. A specified DRX cycle value contained in the configuration information is different from any one of default configurable DRX cycle values.
[0171] In embodiments of the present disclosure, the step 606 may be implemented in any manner as described in various embodiments of the present disclosure, which is not limited in embodiments of the present disclosure, and will not be elaborated here.
[0172] With the method for determining the DRX provided in embodiments of the present disclosure, the network device may indicate to the UE a specified DRX cycle value that matches an arrival time interval of service data when the network device determines that the arrival time interval of any one of the service data is different from each of default configurable DRX cycle values, and perform data transmission with the UE based on the specified DRX cycle value, thereby minimizing the service data transmission delay, and improving the quality and performance of the service.
[0173] Below, a method for determining a DRX provided by embodiments of the present disclosure will be further described with reference to FIG. 7 .
[0174] FIG. 7 is a schematic flowchart of a method for determining a DRX provided by embodiments of the present disclosure, which is applied to a network device.
[0175] As shown in FIG. 7 , the method for determining the DRX includes the following steps.
[0176] In step 701, in response to an arrival time interval of any one of service data being different from any one of the default configurable DRX cycle values, a quotient S of the arrival time interval of the any one of the service data and the duration per slot corresponding to each SCS is determined.
[0177] In step 702, a product of an integer part of the S and the number of symbols per slot corresponding to each SCS is determined as the number of symbols corresponding to a first DRX cycle value included in the specified DRX cycle value in each SCS.
[0178] The time domain resource allocation information of each SCS may include: a duration per slot, the number of symbols per slot, and a duration per symbol.
[0179] For example, if the arrival time interval of service data is 16.66 ms, the duration per slot corresponding to a SCS of 15 kHZ is 1 ms, and the number of symbols per slot is 14, then, for the SCS of 15 kHZ, the quotient S=16.66, and the number of symbols corresponding to the first DRX cycle value included in the specified DRX cycle value in the SCS of 15 kHZ may be determined as 16×14.
[0180] For another example, if the arrival time interval of service data is 16.66 ms, the duration per slot corresponding to a SCS of 30 kHZ is 0.5 ms, and the number of symbols per slot is 14, then, for the SCS of 30 kHZ, the quotient S=33.32, and the number of symbols corresponding to the first DRX cycle value included in the specified DRX cycle value in the SCS of 30 kHZ may be determined as 33×14.
[0181] For a service with the data arrival time interval of 16.66 ms or 33.33 ms, when the product of the integer part of the quotient S of the arrival time interval of the service data and the duration per slot corresponding to each SCS multiplied by the number of symbols per slot corresponding to each SCS is determined as the number of symbols corresponding to the first DRX cycle value included in the specified DRX cycle value in each SCS, values configurable for the first DRX cycle value in each SCS may be as shown in Table 6 below:
[0182]
| TABLE 6 | ||
|---|---|---|
| first DRX cycle value | first DRX cycle value | |
| (corresponding to a | (corresponding to a | |
| service with an | service with an | |
| arrival time interval | arrival time interval | |
| SCS(kHZ) | of 16.66 ms) | of 33.33 ms) |
| 15 | 16 × 14 | 33 × 14 |
| 30 | 33 × 14 | 66 × 14 |
| 60 (normal CP) | 66 × 14 | 133 × 14 |
| 60 (extended CP) | 66 × 14 | 133 × 14 |
| 120 | 133 × 14 | 266 × 14 |
| 240 | 266 × 14 | 533 × 14 |
[0183] It can be understood that each element or each correspondence in Table 6 exist independently. Even though these elements and correspondences are listed in the same table, it does not mean that all the elements and correspondences in Table 6 must exist at the same time as shown in Table 6, and the value of each element and each correspondence do not depend on the value of any other element or any other correspondence in Table 6. Therefore, those skilled in the art can understand that the value of each element and each correspondence in Table 6 correspond to an independent embodiment.
[0184] In step 703, the number of symbols corresponding to a second DRX cycle value included in the specified DRX cycle value in each SCS is determined according to a fractional part of the S and the duration per symbol corresponding to each SCS.
[0185] Optionally, a rounded value of a quotient of the fractional part of the quotient S and the duration per symbol in each SCS may be determined as the number of symbols corresponding to the second DRX cycle value included in the specified DRX cycle value in each SCS.
[0186] For example, for a service with the data arrival time interval of 16.66 ms or 33.33 ms, when the quotient of the fractional part of the S and the duration per symbol in each SCS is rounded up, and the rounded value is determined as the number of symbols corresponding to the second DRX cycle value included in the specified DRX cycle value in each SCS, values configurable for the second DRX cycle value may be shown in Table 7 below.
[0187]

[0188] It can be understood that each element or each correspondence in Table 7 exist independently. Even though these elements and correspondences are listed in the same table, it does not mean that all the elements and correspondences in Table 7 must exist at the same time as shown in Table 7, and the value of each element and each correspondence do not depend on the value of any other element or any other correspondence in Table 7. Therefore, those skilled in the art can understand that the value of each element and each correspondence in Table 7 correspond to an independent embodiment.
[0189] It should be noted that the quotient of the fractional part of the S and the duration per symbol in each SCS may also be rounded down or rounded off, and the rounded value may be determined as the number of symbols corresponding to the second DRX cycle value included in the specified DRX cycle value in each SCS, which is not limited in the present disclosure.
[0190] Optionally, as can be seen from Table 1, there exists a certain multiple relationship among various SCSs in term of the duration per symbol and the duration per slot. In the present disclosure, it is also possible to determine any SCS as a specified SCS, so that after the number of symbols corresponding to the second DRX cycle value in the specified DRX cycle value in the specified SCS is determined, the number of symbols corresponding to the second DRX cycle value in the specified DRX cycle value in each SCS can be determined based on the number of symbols corresponding to the second DRX cycle value in the specified DRX cycle value in the specified SCS.
[0191] That is, in the present disclosure, the rounded value of the quotient of the fractional part of the quotient S and the duration per symbol in the specified SCS may be multiplied by a ratio of the number of slots per frame in each SCS to the number of slots per frame in the specified SCS to obtain a product, and the product may be determined as the number of symbols corresponding to the second DRX cycle value included in the specified DRX cycle value in each SCS.
[0192] In addition, for the extended CP, as compared with the normal CP, when the duration per slot is the same, the number of symbols per slot is different. Therefore, the specified DRX cycle value in the extended CP may be calculated using any method of calculating the specified DRX cycle value as described in the present disclosure.
[0193] For example, for a service with the data arrival time interval of 16.66 ms or 33.33 ms, when a SCS of 15 kHZ is the specified SCS, values configurable for the second DRX cycle value included in the specified DRX cycle value in each SCS may be determined according to the relationship among different SCSs in term of the number of slots per frame as shown in Table 8 below.

[0195] It can be understood that each element or each correspondence in Table 8 exist independently. Even though these elements and correspondences are listed in the same table, it does not mean that all the elements and correspondences in Table 8 must exist at the same time as shown in Table 8, and the value of each element and each correspondence do not depend on the value of any other element or any other correspondence in Table 8. Therefore, those skilled in the art can understand that the value of each element and each correspondence in Table 8 correspond to an independent embodiment.
[0196] It should be noted that, the specified DRX cycle value in each SCS may be calculated using the method as described in any embodiment of the present disclosure as required, which is not limited in the present disclosure.
[0197] Optionally, in the present disclosure, after the number of symbols corresponding to the first DRX cycle value in the specified DRX cycle value in the specified SCS is determined, the number of symbols corresponding to the first DRX cycle value in the specified DRX cycle value in each SCS may also be determined according to the number of symbols corresponding to the first DRX cycle value in the specified DRX cycle value in the specified SCS.
[0198] That is, in the present disclosure, it is possible to first determine the first number of symbols corresponding to the first DRX cycle value and the second number of symbols corresponding to the second DRX cycle value included in the specified DRX cycle value in the specified SCS; and then multiply the first number of symbols by a ratio of the number of slots per frame in each SCS to the number of slots per frame in the specified SCS to determine the number of symbols corresponding to the first DRX cycle value included in the specified DRX cycle value in each SCS; and multiply the second number of symbols by a ratio of the number of slots per frame in each SCS to the number of slots per frame in the specified SCS to determine the number of symbols corresponding to the second DRX cycle value included in the specified DRX cycle value in each SCS.
[0199] In addition, for the extended CP, as compared with the normal CP, when the duration per slot is the same, the number of symbols per slot is different. Therefore, the specified DRX cycle value in the extended CP may be calculated using any method of calculating the specified DRX cycle value as described in the present disclosure.
[0200] For example, for a service with the data arrival time interval of 16.66 ms or 33.33 ms, when a SCS of 15 kHZ is the specified SCS, values configurable for the first DRX cycle value included in the specified DRX cycle value in each SCS may be determined according to the relationship among different SCSs in term of the number of slots per frame as shown in Table 9 below.

[0202] It can be understood that each element or each correspondence in Table 9 exist independently. Even though these elements and correspondences are listed in the same table, it does not mean that all the elements and correspondences in Table 9 must exist at the same time as shown in Table 9, and the value of each element and each correspondence do not depend on the value of any other element or any other correspondence in Table 9. Therefore, those skilled in the art can understand that the value of each element and each correspondence in Table 9 correspond to an independent embodiment.
[0203] In step 704, configuration information of the DRX is sent to a user equipment. A specified DRX cycle value contained in the configuration information is different from any one of default configurable DRX cycle values.
[0204] In embodiments of the present disclosure, the step 704 may be implemented in any manner as described in various embodiments of the present disclosure, which is not limited in embodiments of the present disclosure, and will not be elaborated here.
[0205] With the method for determining the DRX provided in embodiments of the present disclosure, the network device may indicate to the UE a specified DRX cycle value that matches an arrival time interval of service data when the network device determines that the arrival time interval of any one of the service data is different from each of default configurable DRX cycle values, and perform data transmission with the UE based on the specified DRX cycle value, thereby minimizing the service data transmission delay, and improving the quality and performance of the service.
[0206] Below, a method for determining a DRX provided by embodiments of the present disclosure will be further described with reference to FIG. 8 .
[0207] FIG. 8 is a schematic flowchart of a method for determining a DRX provided by embodiments of the present disclosure, which is applied to a network device.
[0208] As shown in FIG. 8 , the method for determining the DRX includes the following steps.
[0209] In step 801, in response to an arrival time interval of any one of service data being different from any one of the default configurable DRX cycle values, a duration corresponding to any one of the default configurable DRX cycle values that is less than the arrival time interval of the any one of the service data is determined as a millisecond value m corresponding to a first DRX cycle value included in a specified DRX cycle value in each SCS.
[0210] In embodiments of the present disclosure, for the specific process of determining the first DRX cycle value included in the specified DRX cycle value in each SCS, reference may be made to the detailed descriptions of any other embodiment, which will not be elaborated here.
[0211] In embodiments of the present disclosure, m is a positive integer.
[0212] In step 802, a first difference value between the arrival time interval of the any one of the service data and the m is determined.
[0213] In step 803, an integer part of the first difference value is determined as a millisecond value f corresponding to a second DRX cycle value included in the specified DRX cycle value.
[0214] As a possible implementation, the specified DRX cycle value may be a combination of a first DRX cycle value, a second DRX cycle value and a third DRX cycle value, and the first DRX cycle value and the second DRX cycle value each may be a millisecond value, and the third DRX cycle value may be the number of sub-milliseconds. Therefore, the integer part of the first difference value may be determined as the millisecond value f corresponding to the second DRX cycle value included in the specified DRX cycle value.
[0215] For example, for a service with the arrival time interval of service data of 16.66 ms, the millisecond value m corresponding to the first DRX cycle value included in the specified DRX cycle value is 10, and the first difference value is 6.66 ms, in this case, the millisecond value f corresponding to the second DRX cycle value included in the specified DRX cycle value in each SCS may be determined to be 6.
[0216] Similarly, for a service with the arrival time interval of service data of 33.33 ms, the millisecond value m corresponding to the first DRX cycle value included in the specified DRX cycle value is 32, and the first difference value is 1.33 ms, in this case, the millisecond value f corresponding to the second DRX cycle value included in the specified DRX cycle value in each SCS may be determined to be 1.
[0217] In step 804, a fourth difference value between the first difference value and the millisecond value f is determined.
[0218] In step 805, a quotient of the fourth difference value and a specified reference coefficient is determined as the number of sub-milliseconds corresponding to a third DRX cycle value included in the specified DRX cycle value in each SCS.
[0219] The specified reference coefficient may be 1/a. It should be noted that, the specific value of a may be determined as required, which is not limited in embodiments of the present disclosure. For example, a may be 32, so the specified reference coefficient is 1/32.
[0220] As a possible implementation, when the specified DRX cycle value is a combination of the first DRX cycle value, the second DRX cycle value and the third DRX cycle value, the first DRX cycle value and the second DRX cycle value each are a millisecond value, and the third DRX cycle value is the number of milliseconds, the quotient of the fourth difference value between the first difference value and the millisecond value f and the specified reference coefficient may be determined as the number of sub-milliseconds corresponding to the third DRX cycle value.
[0221] For example, the arrival time interval of service data is 16.66 ms, and the specified reference coefficient is 1/32. For the DRX long cycle, the first DRX cycle value included in the specified DRX cycle value in each SCS is 10 ms. At this time, the first difference value is 6.66 ms, that is, the second DRX cycle value is 6, and the fourth difference value is 0.66, so that the number of sub-milliseconds corresponding to the third DRX cycle value included in the specified DRX cycle value in each SCS may be determined as 0.66/( 1/32)=21.
[0222] For another example, the arrival time interval of service data is 33.33 ms, and the specified reference coefficient is 1/32. For the DRX long cycle, the first DRX cycle value included in the specified DRX cycle value in each SCS is 32 ms. At this time, the first difference value is 1.33 ms, that is, the second DRX cycle value is 1, and the fourth difference value is 0.33, so that the number of sub-milliseconds corresponding to the third DRX cycle value included in the specified DRX cycle value in each SCS may be determined as 0.33/( 1/32)=11.
[0223] Optionally, when the quotient of the fourth difference value and the specified reference coefficient is not an integer, the quotient of the fourth difference value and the specified reference coefficient may be rounded, and the rounded value may be determined as the number of sub-milliseconds corresponding to the third DRX cycle value included in the specified DRX cycle value. In embodiments of the present disclosure, the rounding may be rounding down, rounding up, or rounding off, and so on.
[0224] In step 806, configuration information of the DRX is sent to a user equipment. A specified DRX cycle value contained in the configuration information is different from any one of default configurable DRX cycle values.
[0225] In embodiments of the present disclosure, the step 806 may be implemented in any manner as described in various embodiments of the present disclosure, which is not limited in embodiments of the present disclosure, and will not be elaborated here.
[0226] With the method for determining the DRX provided in embodiments of the present disclosure, the network device may indicate to the UE a specified DRX cycle value that matches an arrival time interval of service data when the network device determines that the arrival time interval of any one of the service data is different from each of default configurable DRX cycle values, and perform data transmission with the UE based on the specified DRX cycle value, thereby minimizing the service data transmission delay, and improving the quality and performance of the service.
[0227] Below, a method for determining a DRX provided by embodiments of the present disclosure will be further described with reference to FIG. 9 .
[0228] FIG. 9 is a schematic flowchart of a method for determining a DRX provided by embodiments of the present disclosure, which is applied to a network device.
[0229] As shown in FIG. 9 , the method for determining the DRX includes the following steps.
[0230] In step 901, in response to an arrival time interval of any one of service data being different from any one of the default configurable DRX cycle values, a rounded value of a quotient of the arrival time interval of the any one of the service data and the duration per symbol in each SCS may be determined as the number of symbols included in the specified DRX cycle value in each SCS.
[0231] The time domain resource allocation information of each SCS may include: the duration per symbol.
[0232] For example, for a service with the data arrival time interval of 16.66 ms or 33.33 ms, when the quotient of the arrival time interval of the service data and the duration per symbol corresponding to each SCS is rounded down, and the rounded value is determined as the number of symbols included in the specified DRX cycle value in each SCS, values configurable for the specified DRX cycle value in each SCS are shown in Table 10 below.
[0233]

| (corresponding to a | (corresponding to a | |

[0234] It can be understood that each element or each correspondence in Table 10 exist independently. Even though these elements and correspondences are listed in the same table, it does not mean that all the elements and correspondences in Table 10 must exist at the same time as shown in Table 10, and the value of each element and each correspondence do not depend on the value of any other element or any other correspondence in Table 10. Therefore, those skilled in the art can understand that the value of each element and each correspondence in Table 10 correspond to an independent embodiment.
[0235] It should be noted that the quotient of the arrival time interval of the service data and the duration per symbol corresponding to each SCS may also be rounded up or rounded off, and the rounded value may be determined as the number of symbols included in the specified DRX cycle value in each SCS, which is not limited in the present disclosure.
[0236] Optionally, as can be seen from Table 1, there exists a certain multiple relationship among various SCSs in term of the duration per symbol and the duration per slot. In the present disclosure, it is also possible to determine any SCS as the specified SCS, so that after the number of symbols included in the specified DRX cycle value in the specified SCS is determined, the number of symbols included in the specified DRX cycle value in each SCS may be determined based on the number of symbols included in the specified DRX cycle value in the specified SCS.
[0237] That is, in the present disclosure, it is also possible to multiply the rounded value of the quotient of the arrival time interval of the any one of the service data and the duration per symbol in the specified SCS by a ratio of the number of slots per frame in each SCS to the number of slots per frame in the specified SCS, and determine the product obtained thereby as the number of symbols included in the specified DRX cycle value in each SCS.
[0238] In addition, for the extended CP, as compared with the normal CP, when the duration per slot is the same, the number of symbols per slot is different. Therefore, the specified DRX cycle value in the extended CP may be calculated using any method of calculating the specified DRX cycle value as described in the present disclosure.
[0239] For example, for a service with the data arrival time interval of 16.66 ms or 33.33 ms, in the case where a SCS of 15 kHZ is the specified SCS, the number of symbols included in the specified DRX cycle value in each SCS may be determined according to the relationship among different SCSs in term of the number of symbols per frame, as shown in Table 11 below.

[0241] It can be understood that each element or each correspondence in Table 11 exist independently. Even though these elements and correspondences are listed in the same table, it does not mean that all the elements and correspondences in Table 11 must exist at the same time as shown in Table 11, and the value of each element and each correspondence do not depend on the value of any other element or any other correspondence in Table 11. Therefore, those skilled in the art can understand that the value of each element and each correspondence in Table 11 correspond to an independent embodiment.
[0242] In step 902, configuration information of the DRX is sent to a user equipment. A specified DRX cycle value contained in the configuration information is different from any one of default configurable DRX cycle values.
[0243] In embodiments of the present disclosure, the step 902 may be implemented in any manner as described in various embodiments of the present disclosure, which is not limited in embodiments of the present disclosure, and will not be elaborated here.
[0244] With the method for determining the DRX provided in embodiments of the present disclosure, the network device may indicate to the UE a specified DRX cycle value that matches an arrival time interval of service data when the network device determines that the arrival time interval of any one of the service data is different from each of default configurable DRX cycle values, and perform data transmission with the UE based on the specified DRX cycle value, thereby minimizing the service data transmission delay, and improving the quality and performance of the service.
[0245] Below, a method for determining a DRX provided by embodiments of the present disclosure will be further described with reference to FIG. 10 .
[0246] FIG. 10 is a schematic flowchart of a method for determining a DRX provided by embodiments of the present disclosure, which is applied to a network device.
[0247] As shown in FIG. 10 , the method for determining the DRX includes the following steps.
[0248] In step 1001, in response to an arrival time interval of any one of service data being different from any one of the default configurable DRX cycle values, a quotient of the arrival time interval of the any one of the service data and a specified reference coefficient is determined as the number of sub-milliseconds included in the specified DRX cycle value.
[0249] The specified reference coefficient may be 1/a. It should be noted that, the specific value of a may be determined as required, which is not limited in embodiments of the present disclosure. For example, a may be 32, so the specified reference coefficient is 1/32.
[0250] As a possible implementation, the specified DRX cycle value may be represented by the number of sub-milliseconds. Therefore, the quotient of the arrival time interval of the any one of the service data and the specified reference coefficient may be determined as the number of sub-milliseconds included in the specified DRX cycle value.
[0251] For example, the arrival time interval of service data is 16.66 ms, and the specified reference coefficient is 1/32, so the number of sub-milliseconds included in the specified DRX cycle value in each SCS may be determined as 16.66/( 1/32)=533.
[0252] For another example, the arrival time interval of service data is 33.33 ms, and the specified reference coefficient is 1/32, so the number of sub-milliseconds included in the specified DRX cycle value in each SCS may be determined as 33.33/( 1/32)=1067.
[0253] Optionally, when the quotient of the arrival time interval of the any one of the service data and the specified reference coefficient is not an integer, the quotient of the arrival time interval of the any one of the service data and the specified reference coefficient may be rounded, and the rounded obtained thereby may be determined as the number of sub-milliseconds included in the specified DRX cycle value. In embodiments of the present disclosure, the rounding may be rounding down, rounding up, or rounding off, and so on.
[0254] In step 1002, configuration information of the DRX is sent to a user equipment. A specified DRX cycle value contained in the configuration information is different from any one of default configurable DRX cycle values.
[0255] In embodiments of the present disclosure, the step 1002 may be implemented in any manner as described in various embodiments of the present disclosure, which is not limited in embodiments of the present disclosure, and will not be elaborated here.
[0256] With the method for determining the DRX provided in embodiments of the present disclosure, the network device may indicate to the UE a specified DRX cycle value that matches an arrival time interval of service data when the network device determines that the arrival time interval of any one of the service data is different from each of default configurable DRX cycle values, and perform data transmission with the UE based on the specified DRX cycle value, thereby minimizing the service data transmission delay, and improving the quality and performance of the service.
[0257] Below, a method for determining a DRX provided by embodiments of the present disclosure will be further described with reference to FIG. 11 .
[0258] FIG. 11 is a schematic flowchart of a method for determining a DRX provided by embodiments of the present disclosure, which is applied to a UE.
[0259] As shown in FIG. 11 , the method for determining the DRX includes the following steps.
[0260] In step 1101, configuration information of the DRX sent by a network device is received. A specified DRX cycle value contained in the configuration information is different from any one of default configurable DRX cycle values.
[0261] The specified DRX cycle value may be a value of any one of following types of DRX cycles: a DRX long cycle, a DRX short cycle, a scheduling period, a retransmission period, a HARQ period and an inactivity period.
[0262] Optionally, the specified DRX cycle value may be determined by the network device according to a protocol, or may be determined according to requirements of a current service.
[0263] In addition, the above-described configuration information may be a RRC message or a PDCCH control signaling, which is not limited in the present disclosure.
[0264] Optionally, in the present disclosure, when determining that an arrival time interval of any one of service data is different from any one of the default configurable DRX cycle values, the network device may determine the specified DRX cycle value according to the arrival time interval of the any one of the service data.
[0265] For example, AR or VR services can provide users with video streaming services. The typical video frame rate is 30 frames or 60 frames per second, that is, an arrival time interval of video frames is 33.33 ms or 16.66 ms, which however is different from the default configurable DRX cycle values (such as 10 ms, 20 ms, etc.). Therefore, the network device in the present disclosure is able to determine a current specified DRX cycle value according to the arrival time interval of the video service, and send the specified DRX cycle value to the UE, so that the UE is able to perform uplink and downlink data transmissions with the network device based on the specified DRX cycle value.
[0266] Optionally, the specified DRX cycle value may include different content as required. For example, the specified DRX cycle value may include a first DRX cycle value, and the first DRX cycle value may be the number of sub-milliseconds or the number of OFDM symbols.
[0267] For example, for a service with a data arrival time interval of 16.66 ms, the specified DRX cycle value may include the number of sub-milliseconds 533 at 15 kHZ.
[0268] Optionally, the specified DRX cycle value may also include a combination of a first DRX cycle value and a second DRX cycle value, where the first DRX cycle value may be a millisecond value or the number of symbols, and the second DRX cycle value may also be a millisecond value, the number of symbols or the number of sub-milliseconds, etc., which are not limited in the present disclosure.
[0269] For example, for a service with a data arrival time interval of 16.66 ms, the specified resource DRX cycle may include the first DRX cycle value (10 ms) and the second DRX cycle value (10 symbols) at 15 kHZ, where 10 ms is a default configurable DRX cycle value.
[0270] Optionally, the specified DRX cycle value may also include a combination of a first DRX cycle value, a second DRX cycle value and a third DRX cycle value, where the first DRX cycle value may be a millisecond value, the second DRX cycle value may also be a millisecond value, and the third DRX cycle value may be the number of symbols or the number of sub-milliseconds, etc., which are not limited in the present disclosure.
[0271] For example, for a service with a data arrival time interval of 16.66 ms, the specified resource DRX cycle may include the first DRX cycle value (10 ms), the second DRX cycle value (6 ms) and the third DRX cycle value (10 symbols) at 15 kHZ, where 10 ms is a default configurable DRX cycle value.
[0272] In this embodiment, for the manner of determining the specified DRX cycle value, reference may be made to the detailed descriptions of other embodiments of the present disclosure, which will not be elaborated here.
[0273] As a possible implementation, when the specified DRX cycle value includes the number of symbols, the UE may also determine cell information and/or BWP information corresponding to the number of symbols.
[0274] The cell information may include at least one of: a cell group identifier, a cell identifier and a cell type. The BWP information may include at least one of: a BWP identifier and a BWP type.
[0275] Optionally, the configuration information of the DRX received by the UE may include the cell information and/or the BWP information corresponding to the number of symbols. Therefore, after receiving the configuration information of the DRX sent by the network device, the UE may parse the configuration information of the DRX to determine the cell information and/or the BWP information corresponding to the number of symbols.
[0276] Optionally, the network device may also agree on the cell information and/or the BWP information corresponding to the number of symbols through a protocol, so that the UE can determine the cell information and/or the BWP information corresponding to the number of symbols included in the specified DRX cycle value sent by the network device according to the pre-agreed protocol with the network device.
[0277] As a possible implementation, since the activated cell or BWP may be switched during the data transmission between the network device and the UE, and the duration per symbol corresponding to different cells (or BWPs) may be different, when the currently activated cell is different from the cell in the configuration information (or the currently activated BWP is different from the BWP in the configuration information), the UE may update the number of symbols in the specified DRX cycle value according to the currently activated cell or BWP to ensure the accuracy of the determination of the specified DRX cycle value. That is, in a possible implementation of embodiments of the present disclosure, the number of symbols corresponding to the current BWP or cell may be determined in the following manner.
