CROSS LINK INTERFERENCE MEASUREMENT METHOD AND APPARATUS

[0001] This application is a National Stage of International Application No. PCT/CN 2023/096998, field May 30, 2023, which claims priority to Chinese Patent Application No. 202210600614.8, filed May 30, 2022, both of which are incorporated herein by reference herein.

[0002] This disclosure relates to the field of communication technology, in particular to a cross link interference measurement method and apparatus.

[0003] With the rapid growth of uplink service demand, higher demands are put forward for uplink coverage, data transmission rate, and delay. In full-duplex technology, uplink transmission and downlink transmission occur at the same time, which provides an opportunity for enhancing uplink services. As an important topic of R18, the duplex enhancement topic will study subband full-duplex on a base station side. On the base station side, by utilizing subbands, the frequency domain is divided for uplink transmission and downlink transmission, and frequency division can reduce the interference and reduce the complexity of the base station while ensuring simultaneous occurrence of uplink transmission and downlink transmission.

[0004] For subband full-duplex, frequency domain resources are divided into different subbands on the base station side, and downlink transmission and uplink reception are performed in different subbands at the same time. However, for a user equipment (UE), half-duplex is still supported, in other words, at a certain time point, only downlink reception can be performed in the downlink subband or only uplink transmission can be performed in the uplink subband. This will introduce base station-to-base station (gNB-to-gNB) and UE-to-UE cross link interference (CLI), where inter subband CLI is a newly introduced CLI in subband full-duplex. The gNB-to-gNB inter subband CLI is an interference of a transmission signal in the downlink subband of one base station to reception in the uplink subband of another base station. The UE-to-UE inter subband CLI is an interference of a transmission signal in the uplink subband of one UE and reception in the downlink subband of another UE.

[0005] In subband full-duplex, the configurations of subbands can change dynamically, so interference source resources to-be-tested at different times are also different. Thus, the periodic long-term CLI measurement defined in R16 and transmission of the L3 based-CLI measurement result will not meet the demands of dynamically-changed subbands. The transmission of the L3 based-CLI measurement result has a long delay, which cannot effectively track dynamic configurations of subbands in subband full-duplex.

[0006] Embodiments of the disclosure provide a cross link interference (CLI) measurement method. The method includes: receiving CLI measurement configuration information, where the CLI measurement configuration information is contained in CSI resource configuration information, and the CLI measurement configuration information includes CLI resource configuration information and CLI measurement report configuration information; performing CLI measurement on a resource configured through the CLI resource configuration information, according to the CLI measurement report configuration information; and transmitting a CLI measurement report.

[0007] Embodiments of the disclosure further provide another CLI measurement method. The CLI measurement method includes: generating CLI measurement configuration information, where the CLI measurement configuration information is contained in CSI resource configuration information, and the CLI measurement configuration information includes CLI resource configuration information and CLI measurement report configuration information; and transmitting the CLI measurement configuration information.

[0008] Embodiments of the disclosure further provide a cross link interference measurement apparatus. The apparatus includes a transceiver, a memory, and a processor. The memory stores computer programs. The processor is coupled with the memory and the transceiver and is configured to invoke the computer programs to: cause the transceiver to receive CLI measurement configuration information, where the CLI measurement configuration information includes CLI resource configuration information and CLI measurement report configuration information and the CLI measurement report configuration information is contained in a CSI measurement report configuration; perform CLI measurement on a resource configured through the CLI resource configuration information, according to the CLI measurement report configuration information; and cause the transceiver to transmit a CLI measurement report.

[0014] In the current protocol, for the periodic cross link interference (CLI) measurement, the periodic measurement resources are configured through radio resource control (RRC) signaling, and the measurement is performed on the configured measurement resources. The reporting mechanism of the CLI measurement result is layer 3-based reporting, which has a long delay and cannot effectively track the dynamic subband configuration in subband full-duplex.

[0015] In embodiments of the disclosure, since the CLI measurement configuration information is contained in the CSI resource configuration information, the obtained CLI measurement report can be contained in a CSI report. Upon transmission of the CSI report, the CLI measurement report can be transmitted. By transmitting the CSI report via the physical layer, the CLI measurement report can be transmitted via the physical layer. Thus, the transmission delay of the CLI measurement report can be effectively reduced, and the dynamic subband configuration in the subband full-duplex can be effectively tracked.

[0016] For more clear understanding of the above objects, features, and advantageous effects of the disclosure, specific embodiments of the disclosure will be described in detail below with reference to accompanying drawings.

[0017] Embodiments of the disclosure provide a cross link interference measurement method. The method is described in detail in terms of specific steps below with reference to FIG. 1.

The chip system can include a chip and can also include other discrete devices.

[0019] In embodiments of the disclosure, the network device is a device that provides a wireless communication function for the user equipment, and can also be referred to as a radio access network (RAN) device, an access network element, an access network device, or the like. The network device can support at least one wireless communication technology, such as LTE, NR, etc. For example, network devices include, but are not limited to, a next generation node B (gNB) in 5G, an evolved node B (eNB), a radio network controller (RNC), a node B (NB), a base station controller (BSC), a base transceiver station (BTS), a home base station (e.g., home evolved node B, or home node B, HNB), a baseband unit (BBU), a transmitting and receiving point (TRP), a transmitting point (TP), a mobile switching center, and the like.

In some embodiments, the network device can also be an apparatus, such as a chip system, having the function of providing wireless communication for the user equipment. For example, the chip system can include a chip and can also include other discrete devices.

[0020] In some embodiments, the network device can also communicate with an Internet protocol (IP) network, such as the Internet, a private IP network, or other data network, etc.

[0021] In a specific implementation, the cross link interference measurement method described in the following steps 101 to 103 can be executed by a chip with a data processing function in a user equipment, or can be executed by a chip module including the chip with the data processing function in the user equipment.

[0022] Step 101, CLI measurement configuration information is received.

[0023] Step 102, according to the CLI measurement report configuration information, CLI measurement is performed on a resource configured through the CLI resource configuration information.

[0024] In a specific implementation, after channel state information (CSI) resource configuration information is received, CLI resource configuration information and CLI measurement report configuration information can be obtained from the CSI resource configuration information.

[0025] In the prior art, in the CSI resource configuration information (ResourceConfig), a measurement resource set list (nzp-CSI-RS-ResourceSetList) for nzp-CSI-RS, a measurement resource set list (csi-SSB-ResourceSetList) for csi-SSB, and a measurement resource set list (csi-IM-ResourceSetList) for csi-IM are defined.

[0026] In embodiments of the disclosure, the existing CSI resource configuration information is improved, in other words, in addition to the above three measurement resource sets, the CSI resource configuration information includes the CLI measurement configuration information, where the CLI measurement configuration information can include the CLI resource configuration information and the CLI measurement report configuration information.

[0027] In a specific implementation, the CLI resource configuration information can include multiple CLI measurement candidate-resource-set lists and candidate-resource-set list indication information, where the candidate-resource-set list indication information indicates a candidate-resource-set list for CLI measurement.

[0028] In embodiments of the disclosure, csi-CLI-ResourceSetList (that is, the above-described multiple CLI measurement candidate-resource-set lists) can be added to the CSI resource configuration information.

[0029] In a specific implementation, the csi-CLI-ResourceSetList can be contained in the nzp-CSI-RS-ResourceSetList (nzp-CSI-RS measurement resource set list) or can be independent of the nzp-CSI-RS-ResourceSetList.

[0030] The existing CSI-ReportConfig includes information elements (IE) for channel measurement resources, CSI-IM resources for interference (csi-IM-ResourcesForInterference), and nzp-CSI-RS resources for interference (nzp-CSI-RS-ResourcesForInterference), where the measurement resources are associated with corresponding resource indexes (CSI-ResourceConfigId).

[0031] In embodiments of the disclosure, an information element is added to the CSI-ReportConfig, and the information element can represent an association relationship between the CLI measurement candidate-resource-set lists and the candidate-resource-set list indication information (CSI-ResourceConfigId).

[0032] That is, in embodiments of the disclosure, the CLI resource configuration information can include the multiple CLI measurement candidate-resource-set lists (csi-CLI-ResourceSetList) and the candidate-resource-set list indication information (CSI-ResourceConfigId).

[0033] In a specific implementation, the user equipment can perform CLI measurement on the resource configured through the CLI resource configuration information, according to the CLI measurement report configuration information.

[0034] In embodiments of the disclosure, for periodic transmission, each candidate-resource-set list corresponds to one candidate-resource-set, and according to the candidate-resource-set list indication information, which candidate-resource-set list is selected to perform CLI measurement can be determined. Since one candidate-resource-set list corresponds to one candidate-resource-set, when the candidate-resource-set list for CLI measurement is determined, the candidate-resource-set for CLI measurement is also determined.

[0035] In this case, CLI measurement can be performed on the determined candidate-resource-set according to the CLI measurement report configuration information.

[0036] For aperiodic transmission, the number of candidate-resource-sets in one CLI measurement candidate-resource-set list can be multiple, that is, one CLI measurement candidate-resource-set list includes multiple candidate-resource-sets.

[0037] Therefore, in embodiments of the disclosure, the CLI resource configuration information can further include candidate-resource-set indication information, where the candidate-resource-set indication information can indicate a candidate-resource-set for CLI measurement in the determined candidate-resource-set list in aperiodic transmission.

[0038] In CSI-AssociatedReportConfigInfo, an information element is added to indicate the candidate-resource-set for CLI measurement. The trigger status is associated with the CSI report through the newly added information element.

[0039] In embodiments of the disclosure, the newly added information element in the CSI-AssociatedReportConfigInfo is the candidate-resource-set indication information described above.

[0040] In a specific implementation, according to the information element (csi-CLI-ResourcesForInterference), one candidate-resource-set (resource set) in the candidate-resource-set list (csi-CLI-ResourceSetList) is selected for measurement. The value of csi-CLI-ResourcesForInterference ranges from 1 to maxNrofcsi-CLI-ResourceSetsPerConfig, where maxNrofcsi-CLI-ResourceSetsPerConfig represents the largest number of candidate-resource-sets used for CLI measurement in each candidate-resource-set list.

[0041] In a specific implementation, the CLI measurement candidate-resource-set list and the candidate-resource-set list indication information can be transmitted by the network device through RRC signaling. The CLI measurement candidate-resource-set list can be transmitted by the network device through RRC signaling and the candidate-resource-set indication information can be transmitted by the network device through DCI.

[0042] In embodiments of the disclosure, the CLI measurement report configuration information can include a CLI reference signal received power (RSRP), or include a CLI received signal strength indicator (RSSI), or include both the CLI RSRP and the CLI RSSI.

[0043] In embodiments of the disclosure, the CLI measurement report configuration information can be contained in the CSI-ReportConfig. Specifically, the CLI measurement report configuration information can be contained in reportQuantity in CSI-ReportConfig.

[0044] In a specific implementation, the specific process of CLI measurement performed by the user equipment can refer to the existing protocol, and embodiments of the disclosure will not be described in detail.

[0045] Step 103, a CLI measurement report is transmitted.

[0046] In a specific implementation, after a CLI measurement result is obtained, the corresponding CLI measurement report can be generated according to the CLI measurement result, and the obtained CLI measurement report can be transmitted to the network device.

[0047] In embodiments of the disclosure, the CLI measurement report can be contained in the CSI report. Thus, when the CSI report is transmitted to the network device, the CLI measurement report is transmitted to the network device.

[0048] In embodiments of the disclosure, the CSI report can be transmitted via a physical layer (layer 1). Thus, the CLI measurement report is transmitted to the network device via the physical layer (layer 1). The CLI measurement report is transmitted through layer 1, so that the network device can obtain the CLI measurement report only through decoding at the physical layer.

[0049] In the prior art, the CLI measurement report is transmitted through a RRC layer (layer 3), so the CLI measurement report can be obtained through decoding at the physical layer, decoding at a mac layer, and decoding at the RRC layer.

[0050] As can be seen that, compared to transmitting the CLI measurement report through layer 3, transmitting the CLI measurement report through layer 1 can greatly reduce the delay required for transmitting the CLI measurement report, and effectively track the dynamic subband configuration in the subband full-duplex.

[0051] In a specific implementation, the CSI report can also carry a CSI measurement report and a CQI measurement report, and the CSI measurement report includes an RSRP or a signal to interference plus noise ratio (SINR).

[0052] Therefore, in the CSI report, the CLI measurement report may collide with the CSI measurement report and/or the CQI measurement report. When the collision occurs, whether to transmit the CLI measurement report can be determined according to a priority of the CLI measurement report and a priority of the CSI measurement report and/or a priority of the CQI measurement report.

[0053] In embodiments of the disclosure, the priority of the CLI measurement report can be set by the user equipment. The priority of the CLI measurement report can also be determined by the network device and issued by the network device. The user equipment can receive the priority of the CLI measurement report issued by the network device.

[0054] In a specific implementation, the network device can issue the priority of the CLI measurement report through higher layer signaling (such as RRC signaling, MAC CE, etc.), or can issue the priority of the CLI measurement report through downlink control information (DCI).

[0055] In a specific implementation, the user equipment can determine that in the CSI report, the priority of the CSI measurement report is the highest, the priority of the CQI measurement report is the second highest, and the priority of the CLI measurement report is the lowest. In this case, if the CLI measurement report collides with any one of the CSI measurement report and the CQI measurement report, the CLI measurement report needs to be dropped, that is, the CLI measurement report is not transmitted.

[0056] Alternatively, the user equipment can determine that in the CSI report, the priority of the CSI measurement report is the highest, the priority of the CLI measurement report is the second highest, and the priority of the CQI measurement report is the lowest. In this case, if the CLI measurement report collides with the CQI measurement report, the CQI measurement report needs to be dropped, that is, the CQI measurement report is not transmitted.

[0057] According to the prior art, the Pri value of the priority of the i-th CSI report is defined as Pri_iCSI (y, k, c, s)=2·N_cells·M_s·y+N_cells·M_s·k+M_s·c+s, where y=0, 1, 2, and 3 respectively indicate that the type of the channel carrying the CSI report and the time-domain periodicity of the CSI report are: PUSCH and aperiodic, PUSCH and semi-persistent, PUCCH and semi-persistent, and PUCCH and periodic, respectively, and k=0, 1 respectively indicate that the content of the CSI report includes RSRP/SINR or CQI; c represents the ID of the serving cell corresponding to the reference signal corresponding to the CSI report, and s denotes the ID of the CSI report. The smaller the Pri value of the priority of the CSI report, the higher the corresponding priority.

[0058] It can be seen that in the prior art, k=0 is for transmission of the CSI measurement report, and k=1 is for transmission of the CQI measurement report, where the priority of the CSI measurement report is higher than the priority of the CQI measurement report.

[0059] In embodiments of the disclosure, k in the above formula regarding priority can be extended, in other words, k=2 indicates transmission of the CLI measurement report, that is, the priority of the CLI measurement report is lower than the priority of the CQI measurement report.

[0060] Alternatively, k=1 indicates transmission of the CLI measurement report, and k=2 indicates transmission of the CQI measurement report, that is, the priority of the CLI measurement report is higher than the priority of the CQI measurement report and lower than the priority of the CSI measurement report.

[0061] In conclusion, in embodiments of the disclosure, since the CLI measurement configuration information is contained in the CSI resource configuration information, the obtained CLI measurement report can be contained in a CSI report. Upon transmission of the CSI report, the CLI measurement report can be transmitted. By transmitting the CSI report via the physical layer, the CLI measurement report can be transmitted via the physical layer. Thus, the transmission delay of the CLI measurement report can be effectively reduced, and the dynamic subband configuration in the subband full-duplex can be effectively tracked.

[0062] FIG. 2 illustrates another cross link interference CLI measurement method according to embodiments of the disclosure, which will be described in detail below with specific steps.

[0063] In a specific implementation, the cross link interference measurement method described in the following steps 201 to 202 can be executed by a chip with a data processing function in a network device, or can be executed by a chip module including the chip with the data processing function in the network device.

[0064] Step 201, CLI measurement configuration information is generated.

[0065] In embodiments of the disclosure, the CLI measurement configuration information can include multiple CLI measurement candidate-resource-set lists and candidate-resource-set list indication information, where the candidate-resource-set list indication information indicates a candidate-resource-set list for CLI measurement.

[0066] In embodiments of the disclosure, the CLI measurement configuration information can further include the CLI measurement candidate-resource-set list and candidate-resource-set indication information. The candidate-resource-set indication information indicates a candidate-resource-set for CLI measurement in aperiodic transmission in the candidate-resource-set list.

[0067] In embodiments of the disclosure, the CLI measurement report configuration information can be contained in a CSI measurement report configuration. The CLI measurement report configuration information can include CLI reference signal received power, or include CLI received signal strength indicator, or include both the CLI reference signal received power and the CLI received signal strength indicator.

[0068] In a specific implementation, the related content of the CLI measurement configuration information can be referred to the embodiments corresponding to the above steps 101 to 103.

[0069] Step 202, CLI measurement configuration information is transmitted.

[0070] In a specific implementation, the network device can transmit the generated CLI measurement configuration information to a user equipment. After receiving the CLI measurement configuration information, the user equipment can execute the above steps 101 to 103.

[0071] In a specific implementation, the network device can receive a CLI measurement report reported by the user equipment via a physical layer.

[0072] In a specific implementation, the network device can pre-configure a priority of the CLI measurement report and transmit the priority of the CLI measurement report to the user equipment.

[0073] In embodiments of the disclosure, the network device can configure that: in a CSI report, a CSI measurement report has the highest priority, a CQI measurement report has the second highest priority, and the CLI measurement report has the lowest priority. Alternatively, the network device can configure that: in the CSI report, the CSI measurement report has the highest priority, the CLI measurement report has the second highest priority, and the CQI measurement report has the lowest priority.

[0074] In conclusion, it can be seen that in embodiments of the disclosure, the network device configures the CSI resource configuration information to carry the CLI measurement configuration information. The user equipment performs corresponding CLI measurement according to the CLI measurement configuration information, and transmits the CLI measurement report, where the CLI measurement report can be contained in the CSI report. When the CSI report is transmitted, the CLI measurement report can be transmitted. By transmitting the CSI report via the physical layer, the CLI measurement report can be transmitted via the physical layer. Thus, the transmission delay of the CLI measurement report can be effectively reduced, and the dynamic subband configuration in the subband full-duplex can be effectively tracked.

According to the CLI resource configuration information and the CLI measurement report configuration information contained in the CLI measurement configuration information, CLI measurement is performed, to obtain the CLI measurement report.
