To be exact, the use of the word such as “exemplary” or “for example” is intended to present related concepts in a specific manner.

[0113] The related concepts mentioned in the present disclosure are briefly described below.

[0114] The traditional wireless communication adopts a cellular network communication mode, that is, a terminal and a network device perform an uplink and downlink data/control information transmission through a Uu interface.

[0115] The direct communication refers to a mode in which adjacent terminals can perform a data transmission through a direct communication link (also called sidelink or PC5 link, hereinafter referred to as SL) within a short distance. A wireless interface corresponding to the sidelink is called a direct communication interface (also called sidelink interface or PC5 interface).

[0116] The COT sharing mechanism means that after seizing a channel through a listen before talk (LBT) mechanism, terminal A shares its COT with terminal B, where terminal B is a communication peer of a sidelink interface of terminal A, terminal A is also called initiating UE, and terminal B is also called responding UE.

[0117] The embodiments of the present disclosure are described below with reference to the drawings. An information processing method and apparatus, an information transmission method and apparatus, and a terminal according to the embodiments of the present disclosure can be applied to a wireless communication system. The wireless communication system may be a system adopting the 5^th Generation (5G) mobile communication technology (hereinafter collectively referred to as a 5G system). Those skilled in the art will appreciate that a 5G New Radio (NR) system is only an example rather than a limitation.

[0118] The embodiments of the present disclosure provide an information processing method and apparatus, an information transmission method and apparatus, and a terminal, so as to ensure that the responding UE perform a sidelink interface resource allocation smoothly in the COT sharing mechanism.

[0119] In which, the method and the apparatus are based on the same application concept. Since the principles for solving problems by the method and the apparatus are similar, the implementations of the apparatus and the method can refer to each other, and repeated content will not be described.

[0120] As illustrated in FIG. 1, an embodiment of the present disclosure provides an information processing method performed by a first terminal, and the method includes following step S101 and step S102.

[0121] Step S101: receiving Channel Occupancy Time (COT) information from at least one destination identifier (ID).

[0122] It should be noted that the destination ID corresponds to a second terminal. That is, the destination ID is an address of the second terminal, such as a sidelink interface L2 destination ID, a layer 2 address, a layer 3 address, or a media access control (MAC) address. Meanwhile, one second terminal may be corresponding to one or more destination IDs.

[0123] The second terminal refers to a terminal capable of sending COT information, and the first terminal refers to a terminal capable of receiving the COT information sent by the second terminal.

[0124] To be further noted, the COT information may also be called COT sharing information or COT sharing information.

[0125] Step S102: performing selection of a first object based on the COT information.

[0126] Specifically, the first object includes the destination ID and/or a logical channel.

[0127] Optionally, the COT information includes at least one of A11, A12 or A13.

• • [0128] A11: a COT time duration.

[0129] For example, the COT time duration may be an absolute time duration, with units such as subframes, milliseconds (ms), or time slots.

• • [0130] A12: a COT start position.

[0131] For example, the start position represents a time-domain position, which may be specifically identified by one or combinations of a radio frame, a time slot, a subframe, or absolute time. The first terminal may determine a time period corresponding to the COT based on the COT start position and the COT time duration.

• • [0132] A13: a channel access priority class (CAPC) value corresponding to the COT information.

[0133] It should be noted that in this case, the COT information directly carries its corresponding CAPC value. Specifically, the CAPC value is generally an integer, such as 1, 2, 3, 4, or the like.

[0134] The selection of the first object is described in detail below in different cases.

[0135] Optionally, in this case, in another embodiment of the present disclosure, the performing the selection of the first object based on the COT information includes following steps S1021, S1022 and S1023.

[0136] Step S1021: selecting a first destination ID.

[0137] It should be noted that the first destination ID may be understood as a selected destination ID.

[0138] Step S1022: determining, according to the COT information sent from the first destination ID, a CAPC corresponding to the COT information.

[0139] It should be noted here that each COT information corresponds to one CAPC, which may be explicitly indicated (i.e., carried in the COT information) or implicitly indicated.

[0140] Step S1023: performing selection of a logical channel belonging to the first destination ID according to the CAPC;

• • [0141] wherein a CAPC value of the logical channel is less than or equal to a value of the CAPC corresponding to the COT information.

[0142] It should be noted that in the embodiment of the present disclosure, when selection of the logical channel belonging to the first destination ID is performed, the CAPC value of the selected logical channel should be less than or equal to the CAPC value corresponding to the COT information.

[0143] Optionally, in another embodiment of the present disclosure, the performing the selection of the logical channel belonging to the first destination ID according to the CAPC includes:

• • [0144] in case that an SL grant falls within a COT time period indicated by the COT information corresponding to the first destination ID, performing the selection of the logical channel belonging to the first destination ID according to the CAPC.

[0145] That is, only when the SL grant falls within the COT time period indicated by the COT information corresponding to the selected destination ID, the first terminal merely considers the logical channel whose CAPC value is less than or equal to the CAPC value corresponding to the COT information when performing logical channel selection under the selected destination ID.

[0146] Optionally, the selection of the first destination ID may be based on the existing method or the COT information. Taking the selection of the first destination ID based on the COT information as an example, specifically, in another embodiment of the present disclosure, the selecting the first destination ID includes:

• • [0147] in case that an SL grant falls within a COT time period indicated by the COT information sent from a second destination ID, preferentially selecting the second destination ID as the first destination ID when selecting the first destination ID.

[0148] That is, if the SL grant falls within the COT time period indicated by the COT information corresponding to a certain destination ID, the first terminal preferentially selects the destination ID when selecting the destination ID.

[0149] Optionally, in another embodiment of the present disclosure, the method further includes:

• • [0150] obtaining priorities of second objects corresponding to the second destination IDs when the number of the second destination IDs is greater than 1; and
  • [0151] determining the second destination ID with the second object having the highest priority as the first destination ID;
  • [0152] wherein the second object is an SL medium access control control element (MAC CE) and/or a logical channel belonging to the second destination ID.

[0153] This case can be understood as that if the SL grant falls within the COT time periods indicated by the COT information corresponding to a plurality of (two or more) destination IDs, it is necessary to select, based on the priorities of the SL MAC CEs and/or the logical channels corresponding to the destination IDs, a destination ID corresponding to an SL MAC CE and/or a logical channel with a highest priority as the selected destination ID.

[0154] Optionally, in this case, in another embodiment of the present disclosure, the performing the selection of the first object based on the COT information includes:

• • [0155] in case that an SL grant falls within a COT time period indicated by the COT information sent from a third destination ID, preferentially selecting the third destination ID as a selected fourth destination ID when selecting the destination ID.

[0156] That is, if the SL grant falls within the COT time period indicated by the COT information corresponding to a certain destination ID, the first terminal preferentially selects the destination ID when selecting the destination ID.

[0157] Optionally, in another embodiment of the present disclosure, the method further includes:

• • [0158] obtaining priorities of second objects corresponding to the third destination IDs when the number of the third destination IDs is greater than 1; and
  • [0159] determining a third destination ID with the second object having the highest priority as the fourth destination ID;
  • [0160] wherein the second object is an SL MAC CE and/or a logical channel belonging to the third destination ID.

[0161] This case can be understood as that if the SL grant falls within the COT time periods indicated by the COT information corresponding to a plurality of (two or more) destination IDs, it is necessary to select, based on the priorities of the SL MAC CEs and/or the logical channels corresponding to the destination IDs, a destination ID corresponding to an SL MAC CE and/or a logical channel having the highest priority as the selected destination ID.

[0162] It should be noted that in this case, the first terminal only needs to select the destination ID based on the COT information, and the logical channel selection under the selected destination ID is still based on the existing method.

[0163] Further, after the destination ID and the logical channel are selected, resources may be allocated to the selected logical channel, so as to realize a sidelink interface resource allocation.

[0164] Optionally, in another embodiment of the present disclosure, the method further includes:

• • [0165] receiving the COT information through first signaling;
  • [0166] wherein the first signaling includes at least one of:
  • [0167] B11: physical layer signaling;
  • [0168] B12: an SL MAC CE; or
  • [0169] B13: PC5 radio resource control (RRC) signaling.

[0170] The specific application mode of the present disclosure will be described in detail as follows.

[0171] Application case 1: the COT information is considered only during the logical channel selection.

[0172] In this case, the specific implementation process includes following steps S11, S12, S13 and S14.

[0173] Step S11: the destination ID sends the COT information to the first terminal.

[0174] The COT information may be transmitted using physical layer signaling, SL MAC CE or PC5 RRC signaling. The COT information at least includes one or combinations of:

• • [0175] a cot time duration;
  • [0176] a COT start position; or
  • [0177] a value of a CAPC corresponding to the COT information.

[0178] It should be noted that the number of the destination ID(s) may be one or more; and the destination ID corresponds to the second terminal.

[0179] Step S12: the first terminal performs a destination ID selection.

[0180] The first terminal receives one SL grant and performs the destination ID selection in the following process:

• • [0181] for an SL communication, a destination ID with the second object having the highest priority is selected as the selected first destination ID according to the priorities of the second objects corresponding to the destination IDs; the second object is an SL MAC CE and/or a logical channel, and the logical channel shall at least meet the following conditions:
  • [0182] C11: there is transmittable SL data;
  • [0183] C12: a token bucket size SBj corresponding to the logical channel is>0;
  • [0184] C13: if the SL grant is a type 1 pre-configured grant, the type 1 pre-configured grant (sl-configuredGrantType1Allowed) is allowed to be used in configuration information corresponding to the logical channel;
  • [0185] C14: if the SL grant is a pre-configured grant, a pre-configured grant list allowed to be used (sl-AllowedCG-List) in configuration information corresponding to the logical channel contains a pre-configured grant index corresponding to the SL grant; and
  • [0186] C15: if no physical sidelink feedback channel (PSFCH) is configured in the SL grant, a hybrid automatic repeat request (HARQ) attribute (sl-HARQ-FeedbackEnabled) corresponding to the logical channel shall be: disabled.

[0187] Step S13: the first terminal performs selection of a logical channel belonging to the first destination ID selected in Step S12.

[0188] Optionally, in case that no COT information has been sent from the first destination ID selected in Step S12, the logical channel belonging to the first destination ID is selected under the following conditions:

• • [0189] C21: there is transmittable SL data;
  • [0190] C22: if the SL grant is a type 1 pre-configured grant, the type 1 pre-configured grant (sl-configuredGrantType1Allowed) is allowed to be used in configuration information corresponding to the logical channel;
  • [0191] C23: if the SL grant is a pre-configured grant, a pre-configured grant list allowed to be used (sl-AllowedCG-List) in configuration information corresponding to the logical channel contains a pre-configured grant index corresponding to the SL grant; and
  • [0192] C24: the HARQ attribute of the logical channel meets a first condition;
  • [0193] wherein the first condition includes one of:
  • [0194] C241: if the SL grant is configured with a PSFCH, the HARQ attribute of a logical channel with a highest priority belonging to the first destination ID is set to be enabled, and the HARQ attribute of the logical channel is also: enabled;
  • [0195] C242: if the SL grant is configured with a PSFCH, the HARQ attribute of a channel with a highest priority belonging to the first destination ID is set to be disabled, and the HARQ attribute of the logical channel is also: disabled; and
  • [0196] C243: if the SL grant is configured with no PSFCH, the HARQ attribute of the logical channel is: disabled.

[0197] Optionally, in case that the COT information is sent from the first destination ID selected in Step S12 to the first terminal, and the SL grant falls within the time period indicated by the COT information, the logical channel belonging to the destination ID is selected under the following conditions:

• • [0198] C31: a CAPC value of the logical channel is less than or equal to a value of the CAPC corresponding to the COT information;
  • [0199] C32: there is transmittable SL data;
  • [0200] C33: if the SL grant is configured with a PSFCH, the type 1 pre-configured grant (sl-configuredGrantType1Allowed) is allowed to be used in configuration information corresponding to the logical channel;
  • [0201] C34: if the SL grant is a pre-configured grant, a pre-configured grant list allowed to be used (sl-AllowedCG-List) in configuration information corresponding to the logical channel contains a pre-configured grant index corresponding to the SL grant; and
  • [0202] C35: the HARQ attribute of the logical channel meets a second condition;
  • [0203] wherein the second condition includes one of:
  • [0204] C351: if the SL grant is configured with a PSFCH, the HARQ attribute of a channel with a highest priority belonging to the first destination ID is set to be enabled, and the HARQ attribute of the logical channel is also: enabled;
  • [0205] C352: if the SL grant is configured with a PSFCH, the HARQ attribute of a channel with a highest priority belonging to the first destination ID is set to be disabled, and the HARQ attribute of the logical channel is also: disabled; and
  • [0206] C353: if the SL grant is configured with no PSFCH, the HARQ attribute of the logical channel is: disabled.

[0207] Step S14: the first terminal performs a resource allocation.

[0208] For the logical channel selected in Step S13, the resource allocation is performed in the following process:

• • [0209] a first round of resource allocation: allocating resources to the logical channels with SBj>0 according to sPBR in a descending order of the priorities of the logical channels, and updating SBj; and
  • [0210] a second round of resource allocation: if there are any remaining resources, continuing to allocate resources to the logical channels in the descending order of the priorities (regardless of whether SBj is greater than 0) until resources are exhausted or resources are allocated to all data.

[0211] Application case 2: the COT information is considered during both the destination ID selection and the logical channel selection In this case, the specific implementation process includes following steps S21, S22, S23 and S24.

[0212] Step S21: the destination ID sends COT information to the first terminal.

[0213] The COT information may be transmitted using physical layer signaling, SL MAC CE or PC5 RRC signaling. The COT information at least includes one or combinations of:

• • [0214] a Cot time duration;
  • [0215] a COT start position; or
  • [0216] a value of a CAPC corresponding to the COT information.

[0217] It should be noted that the number of the destination ID(s) may be one or more; and the destination ID corresponds to the second terminal.

[0218] Step S22: the first terminal performs a destination ID selection.

[0219] Optionally, in case that none of unicast communication peers of the first terminal sends the COT information to the first terminal, or although the first terminal receives the COT information, the SL grant is not within any COT time period indicated by the COT information, the process of the destination ID selection is as follows:

• • [0220] for an SL communication, a destination ID with the second object having the highest priority is selected as the selected first destination ID according to the priorities of the second objects corresponding to the destination IDs. In which, the second object is an SL MAC CE and/or a logical channel, and the logical channel shall at least meet the following conditions:

[0258] Application case 3: the COT information is considered only during the destination ID selection.

[0259] In this case, the specific implementation process includes following steps S31, S32, S33 and S34.

[0266] Step S32: the first terminal performs a destination ID selection.

[0267] Optionally, in case that none of unicast communication peers of the first terminal sends the COT information to the first terminal, or although the first terminal receives the COT information, the SL grant is not within any COT time period indicated by the COT information, the process of the destination ID selection is as follows:

  • [0286] E33: if the SL grant is a pre-configured grant, a pre-configured grant list allowed to be used (sl-AllowedCG-List) in configuration information corresponding to the logical channel contains a pre-configured grant index corresponding to the SL grant; and
  • [0287] E34: the HARQ attribute of the logical channel meets a fifth condition;
  • [0288] wherein the fifth condition includes one of:
  • [0289] E341: if the SL grant is configured with a PSFCH, the HARQ attribute of a channel with a highest priority belonging to the fourth destination ID is set to be enabled, and the HARQ attribute of the logical channel is also: enabled;

• • [0294] a first round of resource allocation: allocating resources to the logical channels with SBj>0 according to sPBR in a descending order of the priorities of the logical channels, and updating SBj; and
  • [0295] a second round of resource allocation: in case that there are any remaining resources, continuing to allocate resources to the logical channels in the descending order of the priorities (regardless of whether SBj is greater than 0) until resources are exhausted or resources are allocated to all data.

[0296] It should be noted that at least one embodiment of the present disclosure provides an information processing method. If a first terminal receives COT information from a destination ID, the first terminal performs a destination ID selection based on the COT information and/or only considers a logical channel whose CAPC value is less than or equal to a value of the CAPC corresponding to the COT information when performing selection of a logical channel belonging to a selected destination ID after a certain destination ID is selected. By this method, it can be ensured that the terminal can select an appropriate destination ID and/or logical channel when performing LCP in a COT sharing mechanism, and that the terminal can smoothly perform a sidelink interface resource allocation in the COT sharing mechanism, thereby improving the success rate of data transmission.

[0396] It should be noted that these apparatus embodiments are in one-to-one correspondence with the above method embodiments, so all of the implementations in the method embodiments are applicable to the apparatus embodiments and the same technical effect can be achieved.

[0397] It should be noted that the division of the units in the embodiments of the present disclosure is schematic, which is only a division of logical functions, and there may be other division modes in practice. In addition, various functional units in the embodiments of the present disclosure may be integrated into a processing unit, or physically existed separately, or two or more units may be integrated into one unit. The integrated unit may be implemented in the form of hardware, or a software functional unit.

[0398] The integrated unit, if implemented in the form of a software functional unit and sold or used as a separate product, may be stored in a processor-readable storage medium. Based on such understanding, the essence of a technical solution of the present disclosure or a part thereof that contributes to the related art or all or part of the technical solution may be embodied in the form of a software product. The computer software product is stored in a storage medium, and includes a plurality of instructions to cause a computer device (which may be a personal computer, a server, a network device, or the like) or a processor to perform all or part of the steps of the method described in various embodiments of the present disclosure. The storage medium includes various media capable of storing program codes, such as a U disk, a mobile hard disk, a read-only memory (ROM), a random access memory (RAM), a magnetic disk, or an optical disc.

[0399] An embodiment of the present disclosure further provides a terminal, which is a second terminal. The structure of the second terminal is illustrated in FIG. 4, which is not repeated here.

[0400] In which, the processor is configured to read the computer program in the memory and perform the following steps:

• • [0401] sending, by the transceiver, Channel Occupancy Time (COT) information through first signaling, the COT information enabling a first terminal to perform selection of a first object based on the COT information, and the first object including a destination ID and/or a logical channel;
  • [0402] wherein the first signaling includes at least one of:
  • [0403] physical layer signaling;
  • [0404] an SL MAC CE; or

[0410] It should be noted that the above terminal according to the embodiment of the present disclosure can implement all methodical steps implemented by the above method embodiments, and can achieve the same technical effects, so the parts and the advantageous effects of this embodiment the same as those of the method embodiments will not be described in detail.

[0411] The embodiments of the present disclosure further provide a processor-readable storage medium which stores a computer program, wherein when executed by a processor, the computer program implements the steps of the information transmission method applied to the second terminal. The processor-readable storage medium may be any available medium or data storage device accessible to the processor, including but not limited to, a magnetic storage (e.g., a floppy disk, a hard disk, a magnetic tape, magneto-optical (MO) disk, etc.), an optical storage (e.g., a compact disc (CD), a digital video disc (DVD), a Blu-ray Disc (BD), a high-definition versatile disc (HVD), etc.), and a semiconductor memory (e.g., a read-only memory (ROM), an erasable programmable ROM (EPROM), an Electrically EPROM (EEPROM), an NAND FLASH, a solid state disk or solid state drive (SSD)), etc.

[0412] Those skilled in the art will appreciate that an embodiment of the present disclosure may be provided as a method, a system, or a computer program product. Accordingly, the present disclosure may take the form of entirely hardware embodiments, entirely software embodiments, or embodiments combining software and hardware aspects. Moreover, the present disclosure may take the form of a computer program product embodied on one or more computer-usable storage media (including but not limited to a disk storage, an optical storage, etc.) containing computer-usable program codes.

[0413] The present disclosure is described with reference to the flowcharts and/or the block diagrams of the method, the apparatus (system), and the computer program product according to the embodiments of the present disclosure. It should be understood that each flow and/or block in a flowchart and/or a block diagram, and combinations of the flows and/or the blocks in the flowchart and/or the block diagram may be implemented by computer-executable instructions. These computer-executable instructions may be provided to a processor of a general-purpose computer, a special-purpose computer, an embedded processing machine or other programmable data processing device to produce a machine, such that the instructions executed by the processor of the computer or other programmable data processing device create means to realize function(s) specified in one or more flows of the flowchart and/or one or more blocks in the block diagram.

[0414] These processor-executable instructions may also be stored in a processor-readable memory capable of guiding the computer or other programmable data processing device to work in a particular way, such that the instructions stored in the processor-readable memory can produce manufacture articles including an instructing device which realizes function(s) specified in one or more flows in the flowchart and/or one or more blocks in the block diagram.

[0415] These processor-executable instructions may also be loaded onto a computer or other programmable data processing device, such that a series of operation steps can be performed on the computer or other programmable data processing device to produce a processing realized by the computer, thus the instructions executed on the computer or other programmable device provide step(s) for realizing function(s) specified in one or more flows in the flowchart and/or one or more blocks in the block diagram.

[0416] It should be noted that the division of the modules is only a division of logical functions, and in actual implementation, the modules may be entirely or partially integrated into a physical entity, or physically separated. In addition, these modules may all be implemented by calling software with a processing element; or all be implemented in the form of hardware; or some implemented by calling software with a processing element, and some implemented in the form of hardware. For example, a module may be a separately disposed processing element, or may be implemented by being integrated in a chip of the apparatus. In addition, the module may also be stored in the form of program codes in a memory of the apparatus, and a processing element of the apparatus calls and executes the function of the module. The implementations of other modules are similar. In addition, all or part of these modules may be integrated together or independently implemented. The processing element here may be an integrated circuit with a signal processing capability. During implementation, the steps of the above method or the above modules may be completed by a hardware integrated logical circuit in the processor element or instructions in the form of software.

[0417] For example, various modules, units, sub-units, or sub-modules may be one or more integrated circuits configured to implement the above methods, such as one or more application specific integrated circuits (ASICs), or one or more microprocessors (digital signal processors, DSPs), or one or more field programmable gate arrays (FPGAs), etc. For another example, when one of the above modules is implemented by calling program codes with a processing element, the processing element may be a general-purpose processor, such as a central processing unit (CPU) or any other processor capable of calling the program codes. For still another example, these modules may be integrated and implemented in the form of a system-on-a-chip (SOC).

[0418] The terms such as “first” and “second” in the Specification and the claims of the present disclosure are used to distinguish similar objects and are not necessarily to describe a particular order or precedence. It should be understood that the data so used may be interchanged under appropriate circumstances, so that the embodiments of the present disclosure described here, for example, are implemented in an order in addition to those illustrated or described here. Further, the terms “comprise”, “have” and any variations thereof, are intended to cover non-exclusive inclusions, e.g., a process, a method, a system, a product, or a device that includes a series of steps or elements is not necessarily limited to the explicitly listed steps or units, but may include other steps or units not expressly listed or inherent to such process, method, product, or device. In addition, the term “and/or” used in the Specification and the claims means at least one of the connected objects. For example, A and/or B and/or C means that there are seven cases, i.e., A exists alone, B exists alone, C exists alone, both A and B exist, both B and C exist, both A and C exist, and A, B and C all exist. Similarly, “at least one of A and B” in the Specification and the claims should be understood as “A exists alone, B exists alone, or both A and B exist”.

[0419] Obviously, those skilled in the art can make various modifications and variations to the present disclosure without departing from the spirit and the scope of the present disclosure. Thus, when these modifications and variations of the present disclosure fall within the scope of the claims of the present disclosure and the technical equivalents thereof, the present disclosure is also intended to include these modifications and variations.
