[0003] In a wireless communication system, a network side can configure a plurality of beam reporting configurations for a user equipment (UE) to enable the UE to perform beam measurement and report a beam report according to the corresponding beam reporting configuration for different carriers or different channel types.

[0004] In the actual monitoring process of the UE, multiple beam reporting configurations can simultaneously meet the reporting condition, and each beam reporting configuration can report the beam quality of multiple beams. Therefore, how to save resource overhead becomes a problem to be solved. SUMMARY

[0005] Embodiments of the present application provide a communication processing method, device, chip and storage medium. Based on the method described in the present application, the maximum number of beams included in the beam report is indicated, which can control the consumed resources of the uplink channel and save resource overhead.

[0006] In a first aspect, the present application provides a communication processing method, comprising: receiving first indication information from a network device, wherein a first payload of a first beam report transmitted through a first uplink channel is determined based on the first indication information; and transmitting the first beam report to the network device through the first uplink channel based on the first indication information.

[0007] Based on the method described in the first aspect, the payload of the beam report is indicated, which can control the consumed resources of the uplink channel for uploading the beam report and save resource overhead.

[0008] In a possible implementation, the method further includes: receiving at least one beam reporting configuration from the network device, wherein the beam reporting configuration indicates a to-be-measured beam and a trigger condition for triggering sending of the beam report; and wherein the first beam report includes the beam quality of the N target beams, and the target beams are determined based on the to-be-reported beams determined based on the to-be-measured beam in the beam reporting configuration that meets the trigger condition.

[0009] Based on this implementation, in the case that the network device indicates the payload amount of the beam report transmitted through the uplink channel, by the manner that the number of the reported beams is N (the number of the N target beams is less than or equal to the payload amount of the beam report), the load of the terminal device and / or the network device can be further reduced, and the waste of the communication resources can be reduced.

[0010] In a possible implementation, the first payload amount is less than the second payload amount, and the second payload amount is the payload amount required for carrying the beam quality of the to-be-reported beam.

[0011] In a possible implementation, the first beam report further includes the beam quality of the current beam corresponding to the N target beams.

[0012] Based on this implementation, by reporting the beam quality of the N target beams and the current beams corresponding to the N target beams in the beam report, the network device can determine the difference between the beam quality of the target beam and the current beam corresponding to the target beam, and make a decision on the resource configuration (for example, regarding handover, handoff, etc.) of the terminal device.

[0013] In a possible implementation, the N target beams are selected from the to-be-reported beams based on a sorting result of the at least one beam reporting configuration.

[0014] Based on this implementation, by appropriate sorting and using the sorting result, the to-be-reported beams of the beam reporting configuration with high priority can be preferentially selected into the beam report, which is beneficial for the network device to preferentially learn the communication quality of the carrier or channel resource corresponding to the high-priority beam reporting configuration, thereby facilitating the network device to configure the carrier or channel resource corresponding to the high-priority beam reporting configuration.

[0015] In a possible implementation, the N target beams are selected from the to-be-reported beams based on second information corresponding to the at least one beam reporting configuration, wherein the second information indicates the number of the target beams selected from the to-be-reported beams corresponding to the beam reporting configuration, or the second information indicates a first number, and the first number is the sum of the number of the target beams selected from the to-be-reported beams corresponding to the beam reporting configuration and the number of the current beams corresponding to the selected target beams.

[0016] Based on this implementation manner, by reporting the configured reporting of the selected beams on each beam satisfying the triggering condition in the beam report, the network device can comprehensively understand the network environment of the terminal device, so as to subsequently determine appropriate beams from the reported selected beams for the terminal device to perform switching or handover, which can guarantee the communication quality of the terminal device and is beneficial to balancing the load between carriers or resources; in the case that the current beam corresponding to the target beam is also reported, this implementation manner is also beneficial to the network device to determine the difference between the beam quality of the target beam and the current beam corresponding thereto, and is beneficial to the network device to make a decision on the resource configuration (for example, regarding switching, handover, etc.) of the terminal device.

[0017] In a possible implementation manner, the third indication information is also transmitted through the first uplink channel, and the third indication information indicates the number of beam reporting configurations in which no beam is reported among the at least one beam reporting configuration, or the number of the to-be-reported beams that are not reported.

[0018] Based on this implementation manner, the network device can know the number of the to-be-reported beams that are not reported through the third indication information, which is beneficial to determining whether to subsequently schedule the to-be-reported beams that are not reported to obtain the beam measurement results of these to-be-reported beams, thereby being beneficial to the network device to make a decision on the resource configuration (for example, regarding switching, handover, etc.) of the terminal device.

[0019] In a possible implementation manner, the method further includes: receiving fourth indication information from the network device, the fourth indication information indicating the second uplink channel; and based on the fourth indication information, transmitting a second beam report to the network device through the second uplink channel, where the second beam report includes the beam quality of the to-be-reported beams that are not reported.

[0020] Based on this implementation manner, the network device schedules the to-be-reported beams that are not reported, which can obtain the beam measurement results of these previously unreported to-be-reported beams, is beneficial to the network device to comprehensively evaluate the communication environment of the terminal device, and is beneficial to the network device to make a more accurate decision on the resource configuration (for example, regarding switching, handover, etc.) of the terminal device.

[0021] In a possible implementation manner, the method further includes: receiving fifth indication information from the network device, the fifth indication information being used to indicate that the first beam report is correctly received.

[0022] Based on this implementation manner, the network device feeds back the confirmation information to the terminal device to indicate that the beam report is correctly received, which is beneficial to guaranteeing the reliability of the transmission through the uplink channel and is beneficial to guaranteeing the correct transmission of the first beam report.

[0023] In a possible implementation, the method further includes: based on not receiving the fourth indication information and the fifth indication information from the network device, sending the first beam report to the network device again through the first uplink channel; the fourth indication information indicates a second uplink channel for sending a second beam report to the network device, and the second beam report includes beam quality of the to-be-reported beam that is not reported; and the fifth indication information is used to indicate that the first beam report is correctly received.

[0024] Based on this implementation, the terminal device can repeatedly send the first beam report to the network device, which is beneficial to guarantee the reliability of transmission through the uplink channel and is beneficial to guarantee the correct transmission of the first beam report.

[0025] In a possible implementation, the method further includes: based on the number of times of sending the first beam report reaching a threshold, stopping sending the first beam report to the network device.

[0029] Based on this implementation, in the case where the network device indicates the payload amount of the beam report transmitted through the uplink channel, the number of reported beams is N (N target beams are less than or equal to the payload amount of the beam report), which can further be beneficial to reduce the load of the terminal device and / or the network device and reduce the waste of communication resources.

[0030] In a possible implementation, the first payload amount is less than the second payload amount, and the second payload amount is a payload amount required for carrying the beam quality of the to-be-reported beam.

In some embodiments, the beam pairs can be determined independently for the uplink direction based on sounding reference signals (SRSs) transmitted by the UE 220. In various embodiments, beam management can include different stages, such as initial acquisition of uplink beams and downlink beams, refinement of uplink beams and downlink beams, and mobility.

[0082] When in a radio resource control (RRC) idle mode, the UE 220 can perform initial acquisition using SSBs and physical random access channel (PRACH) preambles during a random access procedure to establish uplink and downlink beam pairs. These initial beam pairs can correspond to relatively wide beams. The UE 220 can then enter an RRC connected mode and initiate a beam refinement procedure to select beams that are more directional and have higher gain. The beam refinement procedure can be based on CSI-RSs.

[0083] Beam management can also include mobility operations involving the UE 220 and the base stations 214 / 218 changing beams as radio conditions change over time. Mobility can include inter-cell mobility and intra-cell mobility. Intra-cell mobility can include switching beams within one cell. As shown in FIG. 2, the base stations 214 and 218 can each be divided into three sectors. One cell can correspond to one sector. If the active beam is updated to another beam in the same sector, the mobility event can be considered an intra-cell mobility event. If the active beam is updated to another beam in a different sector or provided entirely by a different base station, the mobility event can be considered an inter-cell mobility event.

[0084] Beam management can be supported by measurements made at various layers of a communication protocol. For example, beam management can include physical layer (or layer 1 (L1)) measurements, medium access control (MAC) layer (or layer 2 (L2)) measurements, and radio resource control (RRC) layer (or layer 3 (L3)) measurements.

[0085] L1 measurements have a small delay and can be used for procedures that benefit from the small delay, e.g., beam management procedures that result in fast switching between beams by the UE 220. L1 measurements are beam level measurements that can be filtered to help reduce the impact of noise and improve measurement accuracy. L2 measurements can be used to measure quality of service (QoS) performance, e.g., packet delay. L3 measurements can reflect longer term characteristics of channel conditions and can be used for radio resource management decisions, e.g., handover procedures. L3 measurements can be beam level or cell level measurements.

[0086] FIG. 3 is a flow diagram of a beam reporting procedure according to embodiments of the present disclosure. In the beam reporting procedure, the base station 314 can be a serving base station of a serving cell and can have an active connection with the UE 320. The base station 318 can be a neighboring base station of a neighboring cell. However, in some embodiments, as shown in the sector example from FIG. 2, a single base station 214 can control both the serving cell and the neighboring cell.

[0087] The beam reporting procedure can be initiated at S301 by the base station 314 sending a beam reporting configuration to the UE 320. The beam reporting configuration can be sent via RRC signaling, can configure the UE 320 with reference signals (e.g., SSB signals or CSI-RS, etc.) to measure beams, and can configure the UE 320 to report a beam report including beam quality (e.g., RSRP, SINR, etc.) of corresponding beams.

[0088] In some embodiments, the beam reporting configuration can also be referred to as a measurement configuration, or any other suitable name, which can include at least resource configuration and reporting configuration, for example. The measurement configuration can configure beams to be measured with the resource configuration, and can configure a manner (e.g., periodic, aperiodic, semi-persistent, etc.) for the UE to report a beam report including corresponding beam quality with the reporting configuration.

[0089] Depending on the implementation, the base station 314 can send one or more beam reporting configurations to the UE 320. It can be appreciated that the one or more beam reporting configurations can be beam reporting configurations configured separately for different carriers or different types of channels. Alternatively, the configurations for different carriers or different types of channels can be distinguished with an identification (ID), and all the configuration information can be sent to the UE in one beam reporting configuration including the configurations of different IDs. The specific form of the beam reporting configuration is not limited in the present disclosure.

[0090] The beam reporting configuration can include one or more of the following parameters: one or more beams to be measured; an indication of a value of a timer that configures periodicity of beam reporting; an indication of a value of a prohibit timer that determines whether a beam report can be triggered within a time window; a trigger condition for triggering a beam report; one or more threshold values for defining the trigger condition; or a scheduling request identity for requesting resources for a beam report. It can be appreciated that the above parameters are merely examples and do not constitute a limitation to the present application.

[0091] In some embodiments, the beam reporting configuration can further include information about a reference signal of a beam that can be periodically transmitted to be detected by the UE 320. The reference signal of the beam can be transmitted by the base station 314 at S302 or by the base station 318 at S303. The reference signal can be an SSB signal or a CSI-RS signal.

[0092] The beam reporting procedure can include the UE 320 measuring the signal at S304 and detecting a trigger condition. The trigger condition can be based on any combination of parameters from the beam reporting configuration or based on measurement results of the periodic reference signal. The present application does not limit this.

[0093] After measuring the signal at S304 and detecting that the trigger condition is satisfied, the beam reporting procedure can further include the UE 320 sending a scheduling request at S305 and receiving a corresponding uplink resource allocation at S306 for the UE 320 to upload a beam report to the base station 314. In some embodiments, the uplink resource can already be available to the UE 320 through a configured grant or through a random access channel resource, thus steps S305 / S306 can not be needed.

[0094] Finally, the beam reporting procedure can include the UE 320 sending a beam report to the base station 314 at S307, reporting beam quality of beams that satisfy the trigger condition.

[0095] In some embodiments, for periodic and semi-persistent beam reporting, the base station configures relevant information of the beam reporting, i.e., the UE needs to periodically report the beam report or periodically report the beam report after receiving an activation command; for aperiodic beam reporting, the UE also needs to report one or more beam reports according to the trigger of the network device.

[0096] However, when the state of the UE does not change (e.g., stationary) or changes little (e.g., the moving speed is small), it is possible that the beam measurement result of the UE does not change or changes little, i.e., the beam report obtained by the current measurement does not change or changes little compared with the beam report that has been reported. At this time, the UE reporting the beam report can cause waste of communication resources. Therefore, a UE self-initiated / event-driven beam reporting mechanism can be configured to reduce the signaling, resource overhead and latency related to beam reporting.

[0097] The UE self-initiated / event-driven beam reporting mechanism can be that the base station configures a trigger condition and related parameters for the UE, and then the UE measures the beams and determines whether the trigger condition is met. If the trigger condition is met, the UE actively reports the measurement result of the related beam, otherwise, the UE does not initiate beam reporting.

[0098] In some embodiments, the trigger condition can be, for example, when at least one new beam in a plurality of candidate new beams has a beam quality higher than that of the current beam by a threshold value, the beam reporting is triggered. Based on such an implementation, the UE can autonomously report the new beam with better beam quality to the base station than the current beam, so that the base station can timely switch the beam for communication with the UE from the current beam to the new beam, thereby ensuring the transmission quality between the base station and the UE.

[0099] Optionally, the UE can report the beam with the highest beam quality in the beam report.

[0100] Optionally, the UE can report a plurality of beams with the highest beam quality in the beam report.

[0101] Optionally, the UE can also report the beam quality of the current beam in the beam report.

[0102] It is easy to understand that the number of beams reported by the UE in the beam report can be pre-set (e.g., configured by a protocol), determined by the base station according to the business demand, or determined according to the upper layer signaling.

[0103] In the process of reporting the beam report, the UE can first send indication information (e.g., 1-bit indication information) to the base station through a PUCCH to inform the base station that the beam report will be sent through a corresponding uplink channel. Then the UE can send the beam report to the base station through the corresponding uplink channel. The resources of the PUCCH and the corresponding uplink channel can be pre-configured by the base station.

[0104] However, in the actual monitoring process of the UE, the trigger condition of one beam reporting configuration can be met, or the trigger conditions of multiple beam reporting configurations can be met at the same time, and one or more beams in each beam reporting configuration that meets the trigger condition can need to be reported. Therefore, the amount of beam reporting varies greatly.

[0105] In some embodiments, the multiple beam reporting configurations can correspond to different PUCCHs and uplink channels respectively. Based on such configurations, when the trigger condition of a beam reporting configuration in the multiple beam reporting configurations is met, the UE can first send indication information to the base station through the PUCCH corresponding to the beam reporting configuration that meets the trigger condition, and then send a beam report to the base station through the corresponding uplink channel. In this way, by using multiple PUCCHs and corresponding uplink channels, the resource configuration of the uplink channel can be easily adapted to the amount of beam reporting of the corresponding beam reporting configuration.

[0106] In some embodiments, the multiple beam reporting configurations can correspond to the same PUCCH and uplink channel. Based on such configurations, when the trigger condition of a beam reporting configuration in the multiple beam reporting configurations is met, the UE can first send indication information to the base station through the PUCCH, and then send a beam report to the base station through the uplink channel. At this time, the resource configuration of the uplink channel is the sum of the number of beams of the multiple beam reporting configurations. In this way, by configuring the uplink channel resource in a manner that meets the maximum resource demand, the overhead of the PUCCH resource can be saved.

[0107] FIG. 4 is a flow diagram of a communication processing method provided by an embodiment of the present application. The method shown in FIG. 4 can be performed by a terminal device, or the subject of the method can be a chip in a terminal device. Wherein:

[0108] S401, receiving first indication information from a network device.

[0109] The first payload of the first beam report transmitted through the first uplink channel is determined based on the first indication information.

[0110] The terminal device can receive the first indication information sent by the network device, and the terminal device can determine the first payload of the first beam report transmitted through the first uplink channel based on the first indication information.

[0111] In the present application, the payload can refer to the amount of information that the beam report can carry, and can indicate the carrying capacity of the beam report with respect to the information to be reported.

[0112] That is, the terminal device can determine the carrying capacity of the beam report transmitted through the first uplink channel based on the first indication information.

[0113] The resource of the first uplink channel providing the corresponding carrying capacity can be determined by the network device based on a network environment or based on upper layer signaling.

[0114] Optionally, the first uplink channel can be a PUSCH.

[0115] In some embodiments, the first indication information can directly indicate a specific value of the first payload amount in the first beam report transmitted through the first uplink channel. That is, the terminal device can directly determine the first payload amount of the first beam report according to the first indication information.

[0116] In some embodiments, the first indication information can be indication of the payload amount of information that the first uplink channel can carry. After the terminal device learns the payload amount of information that the first uplink channel can carry through the first indication information, the terminal device can determine the first payload amount of the first beam report that the first uplink channel can transmit according to the remaining payload amount after excluding some necessary bit overhead.

[0117] In some embodiments, the first indication information can be modulation and coding information. Through the modulation and coding information, information such as modulation order and code rate can be determined, and the terminal device can determine the payload amount of information that the first uplink channel can carry according to the time-frequency resource, modulation order, code rate, and the like of the first uplink channel, and further determine the first payload amount of the first beam report transmitted through the first uplink channel.

[0118] It is easy to understand that the first indication information can explicitly or implicitly indicate the first payload amount of the first beam report transmitted through the first uplink channel in any suitable manner, which is not limited in the present application.

[0119] In some embodiments, the first indication information can be included in dynamic signaling (e.g., DCI signaling). It is easy to understand that the maximum number of beams that can be included in the beam report indicated through the dynamic signaling can enable flexible control of the resource of the first uplink channel for transmitting the beam report, which is conducive to flexible adjustment of the resource overhead of the beam report.

[0120] S402, based on the first indication information, transmitting the first beam report to the network device through the first uplink channel.

[0121] The terminal device can determine the first payload amount of the first beam report transmitted through the first uplink channel, the maximum number of beams that the first beam report transmitted through the first uplink channel can include, and further determine the target beams to be reported, based on the received first indication information, so as to report the beam quality (e.g., RSRP, SINR, etc.) of the target beams in the beam report.

[0122] Generally, in a beam report, the reported information about each beam can have a fixed form (e.g., beam ID + measurement value), and thus the reported information about each beam can be in a form with a fixed number of bits (e.g., 8 bits or any other suitable bit amount). Thus, after the terminal device determines the first payload amount of the first beam report transmitted through the first uplink channel based on the first indication information, the terminal device can determine the maximum number M of beams that can be included in the first beam report transmitted through the first uplink channel according to the ratio of the first payload amount to the fixed number of bits of the beam information.

[0123] In some embodiments, the method can further include receiving at least one beam reporting configuration from the network device, wherein the beam reporting configuration indicates a to-be-measured beam and a triggering condition for triggering sending of a beam report; and wherein the first beam report includes beam qualities of N target beams, the target beams are determined based on the to-be-reported beams, the to-be-reported beams are determined based on the to-be-measured beams in the beam reporting configuration that meets the triggering condition, N is less than or equal to M, and N is a positive integer.

[0124] The terminal device can receive at least one beam reporting configuration from the network device, each of the at least one beam reporting configuration indicating a to-be-measured beam and a triggering condition for triggering sending of a beam report.

[0125] The triggering condition can include, but is not limited to, A1 / A2 / A3 / A4 / A5 / A6 events of the same system and B1 / B2 events of different RATs.

[0126] The six measurement events of the same system can be:

[0127] Event A1: the measurement result of a serving cell is greater than a threshold;

[0128] Event A2: the measurement result of a serving cell is less than a threshold;

[0129] Event A3: the measurement result of a neighbor cell is better than the measurement result of a SpCell (which can be a PCell or a PSCell);

[0130] Event A4: the measurement result of a neighbor cell is greater than a threshold;

[0131] Event A5: the measurement result of a SpCell (which can be a PCell or a PSCell) is less than a threshold 1, and the measurement result of a neighbor cell is greater than a threshold 2;

[0132] Event A6: the measurement result of a neighbor cell is better than the measurement result of a certain secondary serving cell (SCell).

[0133] And the two measurement events of different RATs can be:

[0134] Event B1: the measurement result of the neighbor cell of different RAT is greater than a threshold;

[0135] Event B2: the measurement result of the primary serving cell (PCell) is less than a threshold 1, and the measurement result of the neighbor cell of different RAT is greater than a threshold 2.

[0136] Alternatively, the trigger condition can also include any other suitable event, for example, Event 2 event, that is, when at least one of the to-be-measured beams has a quality higher than the quality of the current beam by a threshold value after measurement, the beam reporting can be triggered.

[0137] When at least one of the to-be-measured beams satisfies the trigger condition, it can be considered that the beam reporting configuration satisfies the trigger condition. The to-be-reported beams can be determined based on the to-be-measured beams of the beam reporting configuration that satisfies the trigger condition.

[0138] In some embodiments, all the to-be-measured beams in the beam reporting configuration that satisfies the trigger condition can be determined as the to-be-reported beams.

[0139] In some embodiments, the to-be-measured beams that satisfy the trigger condition can be determined as the to-be-reported beams.

[0140] In some embodiments, the to-be-measured beams in the beam reporting configuration that satisfies the trigger condition and have a quality higher than the quality of the current beam corresponding to the beam reporting configuration can be determined as the to-be-reported beams.

[0141] Generally, the qualities of these to-be-reported beams will be reported to the network device through the beam report. In this application, the terminal device can determine N target beams from the to-be-reported beams, and then report the qualities of the N target beams to the network device through the first beam report. It is easy to understand that the information amount of the N target beams is less than or equal to the first payload of the first beam report, in other words, N≤M.

[0142] Optionally, N can be configured by the network device and indicated to the terminal device. At this time, N can be the number of beams that need to be reported in the beam report. The network device can determine the value of N based on any suitable manner.

[0143] For example, the network device can predict, based on the previous beam report, that the state of the terminal device has no change (e.g., stationary) or has a small change (e.g., a small moving speed), or can predict, based on a high load of the network device itself, that the terminal device only needs to report a small number of beam qualities by indicating information. For example, for each beam reporting configuration, only the beam quality of the beam with the highest beam quality is reported. This is conducive to reducing the load of the terminal device and / or the network device, and reducing the waste of communication resources.

[0144] For another example, the network device can predict, based on the previous beam report, that the state of the terminal device has a large change, or can predict, based on a small load of the network device itself, that the terminal device can report a large number of beam qualities by indicating information. For example, for each beam reporting configuration, the beam qualities of multiple beams with the highest beam qualities are reported. This is conducive to more comprehensively knowing the network environment of the terminal device, so as to make more accurate decisions on resource configuration of the terminal device and ensure the communication quality of the terminal device.

[0145] Optionally, N can be determined by the terminal device. The terminal device can determine the value of N based on any suitable manner.

[0146] For example, the terminal device can determine, based on its own state having no change (e.g., stationary) or having a small change (e.g., a small moving speed), that only a small number of beam qualities of beams need to be reported in the beam report. For example, for each beam reporting configuration, only the beam quality of the beam with the highest beam quality is reported. This is conducive to reducing the load of the terminal device and / or the network device, and reducing the waste of communication resources.

[0147] For another example, the terminal device can determine, based on its own state having a large change, that a large number of beam qualities can be reported in the beam report. For example, for each beam reporting configuration, the beam qualities of multiple beams with the highest beam qualities are reported. This is conducive to the network device more comprehensively knowing the network environment of the terminal device, so as to make more accurate decisions on resource configuration of the terminal device and ensure the communication quality of the terminal device.

[0148] Optionally, N can be pre-configured through a protocol.

[0149] It is easy to understand that, in the case that the network device indicates the maximum number M of beams that can be included in the beam report transmitted through the uplink channel, by reporting the number N (N≤M) of beams, the load of the terminal device and / or the network device can be further reduced, and the waste of communication resources can be further reduced.

[0150] In particular, in some embodiments, the first load quantity is less than the second load quantity, and the second load quantity is a load quantity required for carrying beam quality of the to-be-reported beams. In this case, by means of the above-mentioned manner of reporting the number of beams N (N≤M), it is particularly advantageous to reduce the load of the terminal device and / or the network device, and to reduce the waste of communication resources.

[0151] In some embodiments, the first beam report can further include beam quality of the current beams corresponding to the N target beams.

[0152] When the terminal device performs beam measurement based on the at least one beam reporting configuration, since each beam reporting configuration can be a beam configuration corresponding to different carriers or different channel types (for example, carrier aggregation and / or dual connectivity scenarios, etc.), for the N target beams in the beam report, there are corresponding current beams when performing beam measurement according to the corresponding beam reporting configuration. The terminal device can include the N target beams and their corresponding current beams in the beam report, and report the beam quality of the N target beams and their corresponding current beams through the beam report, wherein the sum of the number of the N target beams and their corresponding current beams is less than or equal to M.

[0153] It is easy to understand that by reporting the beam quality of the N target beams and their corresponding current beams in the beam report, it is advantageous for the network device to determine the difference in beam quality between the target beam and its corresponding current beam, and it is advantageous for the network device to make decisions on resource configuration of the terminal device (for example, regarding handover, handover, etc.).

[0154] In some embodiments, the N target beams are selected from the to-be-reported beams based on a sorting result of the at least one beam reporting configuration.

[0155] The terminal device can select the N target beams from the to-be-reported beams based on the sorting result of the at least one beam reporting configuration, and report them to the network device through the beam report.

[0156] Optionally, the sorting result can be a sorting based on priority of the beam reporting configuration. The terminal device can select the N target beams to be reported in the beam report from the to-be-reported beams of the beam reporting configuration that meets the triggering condition in turn based on the priority sorting of the beam reporting configuration.

[0157] For example, in a carrier aggregation scenario, the beam reporting configuration for a primary cell (PCell) carrier and the beam reporting configuration for a secondary cell (SCell) carrier both satisfy the triggering condition. Since the priority of the beam reporting configuration for the PCell carrier is higher than the priority of the beam reporting configuration for the SCell carrier, the terminal device can first select target beams to be reported from the beams to be reported in the beam reporting configuration for the PCell carrier, and then select target beams to be reported from the beams to be reported in the beam reporting configuration for the SCell carrier, until the number of target beams to be reported in the beam report is N.

[0158] For example, in a dual connectivity scenario, the beam reporting configuration for a master cell group (MCG) carrier and the beam reporting configuration for a secondary cell group (SCG) carrier both satisfy the triggering condition. Since the priority of the beam reporting configuration for the MCG carrier is higher than the priority of the beam reporting configuration for the SCG carrier, the terminal device can first select target beams to be reported from the beams to be reported in the beam reporting configuration for the MCG carrier, and then select target beams to be reported from the beams to be reported in the beam reporting configuration for the SCG carrier, until the number of target beams to be reported in the beam report is N.

[0159] The beam reporting configurations can be prioritized in any suitable manner, which is not limited in the present application.

[0160] It is easy to understand that, based on the prioritization, the beams to be reported in the beam reporting configuration with high priority can be selected first, which is beneficial for the network device to learn the communication quality of the carrier or channel resource corresponding to the beam reporting configuration with high priority first, thereby facilitating the network device to configure the carrier or channel resource corresponding to the beam reporting configuration with high priority.

[0161] Optionally, the sorting result can be sorting based on the indexes of the beam reporting configurations. The terminal device can select N target beams to be reported in the beam report from the beam reporting configurations that satisfy the triggering condition in order based on the index sorting of the beam reporting configurations.

[0162] For example, when the network device configures the beam reporting configuration, the beam reporting configuration can be assigned an index value (or ID). The terminal device can select target beams to be reported from the beams to be reported in the beam reporting configuration that satisfies the triggering condition in order according to the order of the indexes (or IDs) of the beam reporting configurations, until the number of target beams to be reported in the beam report reaches N.

[0163] In some embodiments, the N target beams are selected from the to-be-reported beams based on second information corresponding to the at least one beam reporting configuration.

[0164] The second information indicates a number of the target beams selected from the to-be-reported beams corresponding to the beam reporting configuration, or the second information is used to indicate a first number, the first number being a sum of the number of the target beams selected from the to-be-reported beams corresponding to the beam reporting configuration and the number of the current beams corresponding to the selected target beams.

[0165] Optionally, the second information can be configured by the network device and indicated to the terminal device.

[0166] For example, the network device can predict that the state of the terminal device has no change (e.g., stationary) or has a small change (e.g., a small moving speed) based on the previous beam report, or can indicate that the terminal device only needs to report a small number of beam qualities for each beam reporting configuration based on a high load of the network device itself through the second information. For example, only the beam quality of the beam with the highest beam quality is reported for each beam reporting configuration. This is conducive to reducing the load of the terminal device and / or the network device, and reducing the waste of communication resources.

[0167] For another example, the network device can predict that the state of the terminal device has a large change based on the previous beam report, or can indicate that the terminal device can report a large number of beam qualities for each beam reporting configuration based on a small load of the network device itself through the second information. For example, the beam qualities of multiple beams with the highest beam quality can be reported for each beam reporting configuration. This is conducive to more comprehensively knowing the network environment of the terminal device, so as to make more accurate decisions on resource configuration of the terminal device and ensure the communication quality of the terminal device.

[0168] Optionally, the second information can be configured through a protocol.

[0169] Optionally, the second information can be determined by the terminal device autonomously.

[0170] For example, the terminal device can determine that only a small number of beam qualities of beams need to be reported in the beam report for each beam reporting configuration based on its own state having no change (e.g., stationary) or having a small change (e.g., a small moving speed), for example, only the beam quality of the beam with the highest beam quality is reported for each beam reporting configuration. This is conducive to reducing the load of the terminal device and / or the network device, and reducing the waste of communication resources.

[0171] For example, the terminal device can determine that a larger number of beam qualities can be reported in the beam report for each beam reporting configuration based on a large change in its own state. For example, for each beam reporting configuration, the beam quality of a plurality of beams with the highest beam quality is reported. This is conducive to the network device comprehensively learning the network environment of the terminal device, so as to make more accurate decisions on resource configuration of the terminal device and ensure the communication quality of the terminal device.

[0172] In the case where the beam quality of the current beam corresponding to the target beam does not need to be included in the beam report, the second information indicates the number of target beams selected from the to-be-reported beams of the corresponding beam reporting configuration when the corresponding beam reporting configuration meets the triggering condition.

[0173] Or, in the case where the beam quality of the current beam corresponding to the target beam needs to be included in the beam report, the second information indicates the sum of the number of target beams selected from the to-be-reported beams of the corresponding beam reporting configuration and the number of current beams corresponding to the selected target beams when the corresponding beam reporting configuration meets the triggering condition.

[0174] In some implementations, the terminal device can receive K beam reporting configurations from the network device, and for beam reporting configuration k (k = 1, 2, …, K) in the K beam reporting configurations, the terminal device can also learn / determine the second information corresponding to the K beam reporting configurations by any suitable manner, which indicates the number of beams N k (k = 1, 2, …, K) that need to be reported when the beam reporting configuration k meets the triggering condition.

[0175] In the case where the beam quality of the current beam corresponding to the target beam does not need to be included in the beam report, the second information can indicate the number of target beams selected from the to-be-reported beams of the corresponding beam reporting configuration when the corresponding beam reporting configuration meets the triggering condition.

[0176] For example, there are 3 to-be-reported beams in the beam reporting configuration k that meets the triggering condition, and the second information corresponding to the beam reporting configuration k indicates N k = 2, which means that 2 target beams are selected from the 3 to-be-reported beams, and the beam quality is reported to the network device through the beam report.

[0177] Preferably, the second information can indicate the number of target beams with the highest beam quality selected from the to-be-reported beams of the corresponding beam reporting configuration when the corresponding beam reporting configuration meets the triggering condition.

[0178] For example, in the foregoing example, N k = 2 indicates that the 2 selected target beams are the 2 beams with the highest beam quality in the 3 to-be-reported beams.

[0179] It is easy to understand that, by reporting one or more beams with the highest beam quality on each beam report configuration that meets the triggering condition in the beam report, the network device can comprehensively understand the network environment of the terminal device, can select appropriate beams from the reported multiple beams for the terminal device to perform switching or handover, can guarantee the communication quality of the terminal device, and is beneficial to balancing the load between carriers or resources.

[0180] In the case where the beam quality of the current beam corresponding to the target beam needs to be included in the beam report, the second information can indicate that, when the corresponding beam report configuration meets the triggering condition, the sum of the number of the target beams selected from the to-be-reported beams of the corresponding beam report configuration and the number of the current beams corresponding to the selected target beams.

[0181] For example, there are 3 to-be-reported beams in the beam report configuration k that meets the triggering condition, and the second information corresponding to the beam report configuration k indicates that N k = 2, which means that 1 target beam is selected from the 3 to-be-reported beams, and the current beam corresponding to the beam report configuration k is added, so that a total of 2 beams are reported to the network device through the beam report.

[0182] It is easy to understand that, by reporting one or more beams with the highest beam quality on each beam report configuration that meets the triggering condition in the beam report and the beam quality of the current beam corresponding to the target beam, the network device can determine the difference between the beam quality of the target beam and the current beam corresponding to the target beam, and make a decision on the resource configuration (for example, regarding switching, handover, etc.) of the terminal device.

[0183] In some embodiments, the terminal device can select, according to the sorting result of the at least one beam report configuration, N k (k = 1, 2, …, K) target beams with the highest beam quality from the to-be-reported beams of the beam report configuration k (k = 1, 2, …, K) in sequence and put them into the beam report, or select N k -1 (k = 1, 2, …, K) target beams with the highest beam quality, add the corresponding current beams, and put them into the beam report, and then report the beam quality of these beams through the beam report.

[0184] Wherein, since the maximum number of beams that can be included in the first beam report transmitted through the first uplink channel is M, the terminal device can select, according to the sorting result of the at least one beam report configuration, N k (k = 1, 2, …, K) target beams with the highest beam quality from the to-be-reported beams of the beam report configuration k (k = 1, 2, …, K) in sequence and put them into the beam report, or select N k-1 (k = 1, 2, …, K) target beams plus the corresponding current beam are put into the beam report, if the beam report can accommodate N k beams of information, the beam quality of the N k beams is put into the beam report, otherwise, the beam report configuration k beam information is not put into the beam report, and so on.

[0185] It can be understood that N k is similar to the N described above, and according to different environments or configurations, N k may be configured by the network device and indicated to the terminal device, or determined by the terminal device itself, or pre-configured through a protocol, which will not be described here.

[0186] Further, in some embodiments, after the selection of the beams to be reported in the K beam reporting configurations according to the second information, the beam report transmitted through the first uplink channel can still accommodate additional beam information.

[0187] At this time, optionally, the terminal device can directly determine the content of the beam report and generate the first beam report, and send the first beam report to the network device through the first uplink channel.

[0188] It is easy to understand that the terminal device directly determines the content of the beam report and generates the first beam report can effectively reduce the processing complexity, save processing resources, and is beneficial to quickly generate the first beam report to feed back part of the information of the beams to be reported to the network device with lower latency.

[0189] Alternatively, the first beam report can be generated by the terminal device by continuing to put the unselected beams to be reported in the beam reporting configuration k (k = 1, 2, …, K) in the beam report according to the order of the beam quality, until the number of beams included in the first beam report is M.

[0190] It is easy to understand that since the maximum number of beams that can be included in the first beam report transmitted through the first uplink channel is M, the resource overhead required for transmitting the beam report through the first uplink channel has been essentially controlled, and there may be some beams to be reported that cannot be reported to the network device through the first beam report due to the resource limitation of the first uplink channel, therefore, it is beneficial to fully utilize the resources of the first uplink channel that has been configured as much as possible, and report the beam information of the maximum number M of beams that can be carried by the first uplink channel in the first beam report, which is beneficial to the network device to more comprehensively know the network environment of the terminal device, and is beneficial to reduce the possibility of communication quality degradation due to insufficient beam measurement information reporting.

[0191] In some embodiments, the third indication information is further transmitted through the first uplink channel, and the third indication information indicates a number of the beam reporting configurations for which no beam to be reported is reported, or a number of the beams to be reported for which no beam is reported.

[0192] Since the maximum number of beams that can be included in the first beam report transmitted through the first uplink channel is M, there can be beams to be reported for which no beam is reported, and there can even be beam reporting configurations for which no beam to be reported is reported.

[0193] In this case, the terminal device can further transmit third indication information to the network device through the first uplink channel.

[0194] In some embodiments, the third indication information can be included in the first beam report, i.e., the third indication information can be subordinate to the first beam report.

[0195] In some embodiments, the third indication information can be information other than the first beam report, i.e., the third indication information can be in a parallel relationship with the first beam report.

[0196] Optionally, the third indication information can indicate the number of beam reporting configurations for which no beam to be reported is reported.

[0197] As can be easily understood, the network device can learn the number of beam reporting configurations for which no beam to be reported is reported through the third indication information, which is conducive to determining whether to subsequently schedule for the beam reporting configurations for which no beam to be reported is reported to obtain the beam measurement results of the beams to be reported corresponding to the beam reporting configurations, thereby facilitating the network device to make decisions on resource configuration (e.g., regarding handover, handover, etc.) of the terminal device.

[0198] Optionally, the third indication information can indicate the number of beams to be reported for which no beam is reported.

[0199] As can be easily understood, the network device can learn the number of beams to be reported for which no beam is reported through the third indication information, which is conducive to determining whether to subsequently schedule for the beams to be reported for which no beam is reported to obtain the beam measurement results of the beams to be reported, thereby facilitating the network device to make decisions on resource configuration (e.g., regarding handover, handover, etc.) of the terminal device.

[0200] Further, in some embodiments, the method further includes: receiving fourth indication information from the network device, the fourth indication information indicating the second uplink channel; and transmitting a second beam report to the network device through the second uplink channel based on the fourth indication information, wherein the second beam report includes the beam quality of the beams to be reported for which no beam is reported.

[0201] After the terminal device sends the first beam report and the third indication information to the network device, the network device can determine, according to the third indication information, that there is still unreported beam information of the unreported beam to be reported on the terminal device side. If the network device wants to obtain the related information (for example, beam quality) of the unreported beam to be reported, the network device can send fourth indication information to the terminal device to schedule a second uplink channel to let the terminal device report the related information of the unreported beam to be reported to the network device. The network device can determine the number of unreported beams to be reported based on the third indication information, so as to determine appropriate time-frequency resources for the second uplink channel.

[0202] Optionally, the fourth indication information can be DCI, which schedules the second uplink channel.

[0203] Optionally, the second uplink channel can be a PUSCH.

[0204] It is easy to understand that the network device schedules the unreported beam to be reported, can obtain the beam measurement result of the previously unreported beam to be reported, is beneficial to the network device to comprehensively evaluate the communication environment of the terminal device, and is beneficial to the network device to make more accurate decisions on resource configuration (for example, about switching, handover, etc.) of the terminal device.

[0205] Alternatively, in some embodiments, the method further includes: receiving fifth indication information from the network device, the fifth indication information being used to indicate that the first beam report is correctly received.

[0206] After the terminal device sends the first beam report (and the third indication information) to the network device, the network device can determine, according to the first beam report (and the third indication information), that there is no unreported beam information on the terminal device side (in this case, the third indication information can be empty or indicate a number of 0). The network device can send fifth indication information to the terminal device to indicate that the first beam report is correctly received.

[0207] Optionally, the fifth indication information can be DCI that does not schedule an uplink channel.

[0208] Optionally, the fifth indication information can be acknowledgement information, for example, ACK information.

[0209] Alternatively, in some embodiments, the method further includes: based on not receiving the fourth indication information and the fifth indication information from the network device, sending the first beam report to the network device again through the first uplink channel; the fourth indication information indicates a second uplink channel for sending a second beam report to the network device, the second beam report including beam quality of the unreported beam to be reported; and the fifth indication information is used to indicate that the first beam report is correctly received.

[0210] After the terminal device sends the first beam report (and the third indication information) to the network device, if the network device does not correctly receive the first beam report, the network device will not send the fourth indication information and the fifth indication information to the terminal device. The terminal device can send the first beam report to the network device again through the first uplink channel based on the fact that the fourth indication information and the fifth indication information are not received from the network device.

[0211] It is easy to understand that the network device sends the confirmation indication to the terminal device, and the terminal device repeatedly sends the first beam report to the network device, which is beneficial to guarantee the reliability of transmission through the uplink channel and is beneficial to guarantee the correct transmission of the first beam report.

[0212] In some embodiments, the method further includes: stopping sending the first beam report to the network device based on the number of times of sending the first beam report reaching a threshold.

[0213] The terminal device can be configured with a number threshold of sending the first beam report. The threshold can be indicated to the terminal device by the network device after being configured by the network device, can be a suitable threshold determined by the terminal device itself, or can be set through a protocol. After the number of times of sending the first beam report reaches the threshold, the terminal device stops sending the first beam report to the network device.

[0214] It can be found that, based on the method of the present application, by determining the first payload of the first beam report based on the first indication information, the resource overhead required for the first uplink channel for transmitting the beam report can be controlled, excessive uplink channel resources can be avoided due to too many beams needing to be reported to meet the triggering condition, and excessive waste of the pre-configured uplink channel resources can be avoided due to too few beams needing to be reported to meet the triggering condition.

[0215] FIG. 5 is a flow diagram of a communication processing method according to an embodiment of the present application. The method shown in FIG. 5 can be performed by a network device, or the subject can be a chip in the network device. Wherein:

[0216] S501, sending first indication information to a terminal device.

[0217] The first payload of the first beam report transmitted through the first uplink channel is determined based on the first indication information.

[0218] The network device can send the first indication information to the terminal device, and the terminal device can determine the maximum payload of the beam report transmitted through the first uplink channel based on the first indication information.

[0219] In the present application, the payload can refer to the amount of information of the effective information that the beam report can carry, and can indicate the carrying capacity of the beam report with respect to the information to be reported.

[0220] That is, the terminal device can determine the carrying capacity of the beam report transmitted through the first uplink channel based on the first indication information.

[0221] The resource of the first uplink channel providing the corresponding carrying capacity can be determined by the network device based on the network environment, or determined based on upper layer signaling.

[0222] Optionally, the first uplink channel can be a PUSCH.

[0223] In some embodiments, the first indication information can directly indicate a specific value of the first payload amount in the first beam report transmitted through the first uplink channel. That is, the terminal device can directly determine the first payload amount of the first beam report according to the first indication information.

[0224] In some embodiments, the first indication information can be indication of the payload amount of information that the first uplink channel can carry. After the terminal device learns the number of information bits that the first uplink channel can carry through the first indication information, the terminal device can determine the first payload amount of the first beam report that the first uplink channel can transmit according to the remaining payload amount after excluding some necessary bit overhead.

[0225] In some embodiments, the first indication information can be modulation and coding information. Through the modulation and coding information, information such as modulation order, code rate, etc. can be determined, and the terminal device can determine the number of payload bits of information that the first uplink channel can carry according to the time-frequency resource, modulation order, code rate, etc. of the first uplink channel, and further determine the first payload amount of the first beam report transmitted through the first uplink channel.

[0226] It is easy to understand that the first indication information can explicitly or implicitly indicate the first payload amount of the first beam report transmitted through the first uplink channel in any suitable manner, which is not limited in the present application.

[0227] In some embodiments, the first indication information can be included in dynamic signaling (e.g., DCI signaling). It is easy to understand that the maximum number of beams that can be included in the beam report indicated through the dynamic signaling can achieve flexible control of the resource of the first uplink channel transmitting the beam report, which is beneficial to flexible adjustment of the resource overhead of the beam report.

[0228] S502, receiving the first beam report reported by the terminal device based on the first indication information through the first uplink channel.

[0229] The terminal device can determine the first payload of the first beam report transmitted through the first uplink channel based on the received first indication information, determine the maximum number of beams that the first beam report transmitted through the first uplink channel can include, and determine the beams to be reported from the beams that satisfy the triggering condition, so as to report the beam quality (for example, RSRP, SINR, etc.) of the beams in the beam report. After sending the first indication information, the network device can listen to the first uplink channel and receive the first beam report reported by the terminal device based on the first indication information.

[0230] It is easy to understand that the amount of information of the beams reported in the beam report is less than or equal to the maximum payload of the beam report. Alternatively, the number of beams reported in the beam report can be less than or equal to M.

[0231] Generally, the reported information about each beam in the beam report can have a fixed form (for example, beam ID + measurement value), so the reported information of each beam can be in the form of a fixed number of bits (for example, 8 bits or any other suitable bit amount), and therefore, the terminal device learns the maximum payload of the beam report transmitted through the first uplink channel through the first indication information, and the terminal device can determine the maximum number M of beams that can be included in the beam report transmitted through the first uplink channel according to the maximum payload and the fixed number of bits.

[0232] In some embodiments, the method can further include: sending at least one beam reporting configuration to the terminal device, wherein the beam reporting configuration indicates a to-be-measured beam and a triggering condition for triggering sending of a beam report; wherein the first beam report includes the beam quality of N target beams; the target beams are determined based on the to-be-reported beams, and the to-be-reported beams are determined based on the to-be-measured beams in the beam reporting configuration that satisfies the triggering condition; N is less than or equal to M, and N is a positive integer.

[0233] The network device can send at least one beam reporting configuration to the terminal device, each of the at least one beam reporting configuration indicating a to-be-measured beam and a triggering condition for triggering sending of a beam report.

[0234] The triggering condition can include, but is not limited to, A1 / A2 / A3 / A4 / A5 / A6 events of the same system and B1 / B2 events of different RATs.

[0235] The six measurement events of the same system can be:

[0236] Event A1: The measurement result of the serving cell is greater than a threshold;

[0237] Event A2: The measurement result of the serving cell is less than a threshold;

[0238] Event A3: a neighbor cell measurement result is better than a SpCell (may be PCell or PSCell) measurement result;

[0239] Event A4: a neighbor cell measurement result is greater than a threshold;

[0240] Event A5: a SpCell (may be PCell or PSCell) measurement result is less than a threshold 1, while a neighbor cell measurement result is greater than a threshold 2;

[0241] Event A6: a neighbor cell measurement result is better than a certain secondary serving cell (SCell) measurement result.

[0242] And, two measurement events of different RATs can be:

[0243] Event B1: a different RAT neighbor cell measurement result is greater than a threshold;

[0244] Event B2: a primary serving cell (PCell) measurement result is less than a threshold 1, while a different RAT neighbor cell measurement result is greater than a threshold 2.

[0245] Or, the triggering condition can also include any other suitable event, for example, Event 2 event, that is, when at least one to-be-measured beam is measured to have a quality higher than a threshold value than the quality of the current beam among multiple to-be-measured beams, the beam reporting can be triggered.

[0246] When at least one to-be-measured beam satisfies the triggering condition among the to-be-measured beams indicated by each beam reporting configuration in the at least one beam reporting configuration, it can be considered that the beam reporting configuration satisfies the triggering condition. The to-be-reported beam whose beam quality is to be reported to the network device can be determined based on the to-be-measured beam of the beam reporting configuration that satisfies the triggering condition.

[0247] In some embodiments, all to-be-measured beams in the beam reporting configuration that satisfies the triggering condition can be determined as to-be-reported beams.

[0248] In some embodiments, the to-be-measured beam that is measured to satisfy the triggering condition among the to-be-measured beams can be determined as the to-be-reported beam.

[0249] In some embodiments, the to-be-measured beam in the beam reporting configuration that satisfies the triggering condition and has a beam quality higher than the beam quality of the current beam corresponding to the beam reporting configuration can be determined as the to-be-reported beam.

[0250] Generally, the beam quality of the beams to be reported will be reported to the network device through the beam report. In this application, the terminal device can determine N target beams from the beams to be reported, and then report the beam quality of the N target beams to the network device through the first beam report. It is easy to understand that the information amount of the N target beams is less than or equal to the first load amount of the first beam report, in other words, N≤M.

[0251] Optionally, N can be configured by the network device and indicated to the terminal device. At this time, N can be the number of beams that need to be reported in the beam report. The network device can determine the value of N based on any suitable manner.

[0252] For example, the network device can predict that the state of the terminal device has no change (for example, stationary) or small change (for example, small moving speed) based on the previous beam report, or can indicate that the terminal device only needs to report a smaller number of beam qualities through the indication information based on the fact that the network device itself has a high load. For example, only the beam quality of the beam with the highest beam quality is reported for each beam reporting configuration. This is beneficial to reduce the load of the terminal device and / or the network device, and reduce the waste of communication resources.

[0253] For another example, the network device can predict that the state of the terminal device has a large change based on the previous beam report, or can indicate that the terminal device can report a larger number of beam qualities through the indication information based on the fact that the network device itself has a small load. For example, the beam quality of multiple beams with the highest beam quality can be reported for each beam reporting configuration. This is beneficial to more comprehensively know the network environment of the terminal device, so as to make more accurate decisions on resource configuration of the terminal device and ensure the communication quality of the terminal device.

[0254] Optionally, N can be determined by the terminal device. The terminal device can determine the value of N based on any suitable manner.

[0255] For example, the terminal device can determine that only the beam quality of a smaller number of beams needs to be reported in the beam report based on the fact that its own state has no change (for example, stationary) or small change (for example, small moving speed), for example, only the beam quality of the beam with the highest beam quality is reported for each beam reporting configuration. This is beneficial to reduce the load of the terminal device and / or the network device, and reduce the waste of communication resources.

[0256] For another example, the terminal device can determine that a larger number of beam qualities can be reported in the beam report based on the fact that its own state has a large change. For example, the beam quality of multiple beams with the highest beam quality is reported for each beam reporting configuration. This is beneficial to the network device to more comprehensively know the network environment of the terminal device, so as to make more accurate decisions on resource configuration of the terminal device and ensure the communication quality of the terminal device.

[0257] Optionally, N can be pre-configured through a protocol.

[0258] It is easy to understand that, in the case of the maximum number M of beams that can be included in the beam report indicated by the network device through the uplink channel, by reporting the number of beams N (N≤M), the load of the terminal device and / or the network device can be further reduced, and the waste of communication resources can be reduced.

[0259] In particular, in some embodiments, the first load is less than the second load, and the second load is the load required to carry the beam quality of the beams to be reported. In this case, by reporting the number of beams N (N≤M), it is particularly advantageous to reduce the load of the terminal device and / or the network device, and to reduce the waste of communication resources.

[0260] In some embodiments, the first beam report can further include the beam quality of the current beam corresponding to the N target beams.

[0261] When the terminal device performs beam measurement based on the at least one beam reporting configuration, since each beam reporting configuration can be a beam configuration corresponding to different carriers or different channel types (for example, carrier aggregation and / or dual connectivity scenarios, etc.), for the N target beams in the beam report, there is a corresponding current beam when performing beam measurement according to the corresponding beam reporting configuration. The terminal device can include the N target beams and their corresponding current beams in the beam report, and report the beam quality of the N target beams and their corresponding current beams through the beam report, wherein the sum of the number of the N target beams and their corresponding current beams is less than or equal to M.

[0262] It is easy to understand that, by reporting the beam quality of the N target beams and their corresponding current beams in the beam report, it is advantageous for the network device to determine the difference in beam quality between the target beam and its corresponding current beam, and for the network device to make decisions on resource configuration of the terminal device (for example, regarding handover, handover, etc.).

[0263] In some embodiments, the N target beams are selected from the beams to be reported based on the sorting result of the at least one beam reporting configuration.

[0264] The terminal device can select the N target beams from the beams to be reported based on the sorting result of the at least one beam reporting configuration, and report them to the network device through the beam report.

[0265] Optionally, the sorting result can be a sorting based on a priority of the beam reporting configuration. The terminal device can select, based on the priority of the beam reporting configuration, the N target beams to be reported in the beam report from the to-be-reported beams of the beam reporting configuration that meet the triggering condition in sequence.

[0266] For example, in a carrier aggregation scenario, the beam reporting configuration for a primary cell (PCell) carrier and the beam reporting configuration for a secondary cell (SCell) carrier both meet the triggering condition. Since the priority of the beam reporting configuration for the PCell carrier is higher than the priority of the beam reporting configuration for the SCell carrier, the terminal device can select the target beams to be reported from the to-be-reported beams of the beam reporting configuration for the PCell carrier first, and then select the target beams to be reported from the to-be-reported beams of the beam reporting configuration for the SCell carrier, until the number of the target beams to be reported in the beam report is N.

[0267] For example, in a dual connectivity scenario, the beam reporting configuration for a primary cell (PCell) carrier and the beam reporting configuration for a secondary cell (SCell) carrier both meet the triggering condition. Since the priority of the beam reporting configuration for the MCG carrier is higher than the priority of the beam reporting configuration for the SCG carrier, the terminal device can select the target beams to be reported from the to-be-reported beams of the beam reporting configuration for the MCG carrier first, and then select the target beams to be reported from the to-be-reported beams of the beam reporting configuration for the SCG carrier, until the number of the target beams to be reported in the beam report is N.

[0268] The beam reporting configuration can be prioritized in any suitable manner, which is not limited in the present application.

[0269] It is easy to understand that, based on the priority sorting, the to-be-reported beams of the beam reporting configuration with high priority can be selected into the beam report first, which is beneficial for the network device to learn the communication quality of the carrier or channel resource corresponding to the high-priority beam reporting configuration first, thereby facilitating the network device to configure the carrier or channel resource corresponding to the high-priority beam reporting configuration.

[0270] Optionally, the sorting result can be a sorting based on an index of the beam reporting configuration. The terminal device can select, based on the index of the beam reporting configuration, the N target beams to be reported in the beam report from the beam reporting configuration that meets the triggering condition in sequence.

[0271] For example, when the network device configures the beam reporting configuration, the network device can assign an index value (or ID) to the beam reporting configuration. The terminal device can select the target beam to be reported from the to-be-reported beams of the beam reporting configuration that meet the triggering condition in turn according to the order of the indexes (or IDs) of the beam reporting configurations, until the number of the target beams to be reported in the beam report reaches N.

[0272] In some embodiments, the N target beams are selected from the to-be-reported beams based on second information corresponding to the at least one beam reporting configuration.

[0273] The second information indicates the number of the target beams selected from the to-be-reported beams of the corresponding beam reporting configuration, or the second information indicates a first number, the first number being a sum of the number of the target beams selected from the to-be-reported beams of the beam reporting configuration corresponding to the second indication information and the number of the current beam corresponding to the selected target beams.

[0274] Optionally, the second information can be configured and indicated to the terminal device by the network device.

[0275] For example, the network device can predict that the state of the terminal device does not change (for example, stationary) or changes little (for example, the moving speed is small) based on the previous beam report, or can indicate the terminal device to report only a small number of beam qualities for each beam reporting configuration through the second information based on the high load of the network device itself. For example, for each beam reporting configuration, only the beam quality of the beam with the highest beam quality is reported. This is beneficial to reduce the load of the terminal device and / or the network device, and reduce the waste of communication resources.

[0276] For another example, the network device can predict that the state of the terminal device changes greatly based on the previous beam report, or can indicate the terminal device to report a large number of beam qualities for each beam reporting configuration through the second information based on the small load of the network device itself. For example, for each beam reporting configuration, the beam qualities of multiple beams with the highest beam quality can be reported. This is beneficial to more comprehensively know the network environment of the terminal device, so as to make more accurate decisions on resource configuration of the terminal device and ensure the communication quality of the terminal device.

[0277] Optionally, the second information can be configured through a protocol.

[0278] Optionally, the second information can be determined by the terminal device autonomously.

[0279] For example, the terminal device can determine that, based on its own state not changing (e.g., stationary) or changing little (e.g., moving at a small speed), the beam report needs to report only a small number of beam qualities of beams for each beam reporting configuration. For example, for each beam reporting configuration, only the beam quality of the beam with the highest beam quality is reported. This helps to reduce the load of the terminal device and / or the network device, and reduce the waste of communication resources.

[0280] For another example, the terminal device can determine that, based on its own state changing greatly, the beam report needs to report a large number of beam qualities of beams for each beam reporting configuration. For example, for each beam reporting configuration, the beam qualities of multiple beams with the highest beam qualities are reported. This helps the network device to more comprehensively know the network environment of the terminal device, so as to make more accurate decisions on resource configuration of the terminal device and ensure the communication quality of the terminal device.

[0281] In the case where the beam report does not need to include the beam quality of the current beam corresponding to the target beam, the second indication information indicates the number of target beams selected from the to-be-reported beams of the corresponding beam reporting configuration when the corresponding beam reporting configuration meets the triggering condition.

[0282] Or, in the case where the beam report needs to include the beam quality of the current beam corresponding to the target beam, the second indication information indicates the sum of the number of target beams selected from the to-be-reported beams of the corresponding beam reporting configuration and the number of current beams corresponding to the selected target beams when the corresponding beam reporting configuration meets the triggering condition.

[0283] In some implementations, the network device can send K beam reporting configurations to the terminal device. For a beam reporting configuration k (k = 1, 2, …, K) of the K beam reporting configurations, the terminal device can also learn / determine, by any suitable manner, second information corresponding to the K beam reporting configurations, the second information indicating the number N k (k = 1, 2, …, K) of beams that need to be reported when the beam reporting configuration k meets the triggering condition.

[0284] In the case where the beam report does not need to include the beam quality of the current beam corresponding to the target beam, the second information can indicate the number of target beams selected from the to-be-reported beams of the corresponding beam reporting configuration when the corresponding beam reporting configuration meets the triggering condition.

[0285] For example, there are 3 to-be-reported beams in the beam reporting configuration k that meets the triggering condition, and the second information corresponding to the beam reporting configuration k indicates N k = 2, which means that 2 target beams are selected from the 3 to-be-reported beams, and the beam quality is reported to the network device through the beam report.

[0286] Preferably, the second information can indicate the number of target beams selected from the to-be-reported beams of the corresponding beam reporting configuration when the corresponding beam reporting configuration meets the triggering condition.

[0287] For example, in the foregoing example, N k = 2 indicates that the two selected target beams are the two beams with the highest beam quality among the three to-be-reported beams.

[0288] It is easy to understand that, by reporting the beam with the highest beam quality or the beams with the highest beam quality and the corresponding current beams for each beam reporting configuration meeting the triggering condition in the beam report, the network device can relatively comprehensively understand the network environment of the terminal device, select appropriate beams from the reported multiple beams for the terminal device to perform switching or handover, which can guarantee the communication quality of the terminal device and is also conducive to balancing the load between carriers or resources.

[0289] In the case where the beam quality of the current beam corresponding to the target beam needs to be included in the beam report, the second information can indicate that, when the corresponding beam reporting configuration meets the triggering condition, the sum of the number of target beams selected from the to-be-reported beams of the corresponding beam reporting configuration and the number of current beams corresponding to the selected target beams.

[0290] For example, there are three to-be-reported beams in the beam reporting configuration k meeting the triggering condition, and the second information corresponding to the beam reporting configuration k indicates that N k = 2, which means that one target beam is selected from the three to-be-reported beams, and the current beam corresponding to the beam reporting configuration k is added, so that a total of two beams are reported to the network device through the beam report.

[0291] It is easy to understand that, by reporting the beam with the highest beam quality or the beams with the highest beam quality and the corresponding current beams for each beam reporting configuration meeting the triggering condition in the beam report, the network device can relatively comprehensively understand the network environment of the terminal device, select appropriate beams from the reported multiple beams for the terminal device to perform switching or handover, which can guarantee the communication quality of the terminal device and is also conducive to balancing the load between carriers or resources.

[0292] In some embodiments, the terminal device can select, according to the sorting result of the at least one beam reporting configuration, N k (k = 1, 2, …, K) target beams with the highest beam quality from the to-be-reported beams of the beam reporting configuration k (k = 1, 2, …, K) in order and put them into the beam report, or select N k -1 (k = 1, 2, …, K) target beams with the highest beam quality and add the corresponding current beams to the beam report, and then report the beam quality of these beams through the beam report.

[0293] wherein, since the maximum number of beams that can be included in the first beam report transmitted through the first uplink channel is M, from the beams to be reported in the beam reporting configuration k (k = 1, 2, …, K) in order, the N k (k = 1, 2, …, K) target beams with the highest beam quality are selected and put into the beam report, or the N k (k = 1, 2, …, K) target beams plus the corresponding current beam are selected and put into the beam report, and if the beam report can accommodate the information of the N k (k = 1, 2, …, K) beams, the beam quality of the N k (k = 1, 2, …, K) beams is put into the beam report, otherwise, the beam information of the beam reporting configuration k is not put into the beam report, and so on.

[0294] It can be understood that N k is similar to the N described above, and N k may be configured by the network device and indicated to the terminal device according to different environments or configurations, may be determined by the terminal device itself, or may be pre-configured through a protocol, which will not be described here.

[0295] Further, in some embodiments, after the selection of the beams to be reported in the K beam reporting configurations according to the second information in order, the beam report transmitted through the first uplink channel may still be able to accommodate additional beam information.

[0296] At this time, optionally, the first beam report can be determined and generated by the terminal device directly, and the network device can receive the first beam report from the terminal device through the first uplink channel.

[0297] It is easy to understand that the terminal device directly determines and generates the first beam report can effectively reduce the processing complexity, save the processing resources, and be conducive to quickly generating the first beam report, so that the network device can first learn the information of part of the beams to be reported with a lower delay.

[0298] Alternatively, optionally, the first beam report can be generated by the terminal device by continuing to put the unselected beams to be reported in the beam reporting configuration k (k = 1, 2, …, K) in order according to the ordering result of the at least one beam reporting configuration, in order of beam quality, until the number of beams included in the first beam report is M.

[0299] It is easy to understand that since the maximum number of beams that can be included in the first beam report transmitted through the first uplink channel is M, the resource overhead required for the first uplink channel for transmitting the beam report has been substantially controlled, and there may be some to-be-reported beams that cannot be reported to the network device through the first beam report due to the resource limitation of the first uplink channel. Therefore, it is beneficial to fully utilize the resources of the first uplink channel as much as possible, report the beam information of the maximum number M of beams that the first uplink channel can carry in the first beam report, help the network device to more comprehensively know the network environment of the terminal device, and help to reduce the possibility of communication quality degradation due to insufficient reporting of beam measurement information.

[0300] In some embodiments, the third indication information is further received through the first uplink channel, and the third indication information indicates the number of beam reporting configurations in which no to-be-reported beam is reported, or the number of to-be-reported beams that are not reported.

[0301] Since the maximum number of beams that can be included in the first beam report transmitted through the first uplink channel is M, there may be to-be-reported beams that are not reported for at least one beam reporting configuration, and there may even be beam reporting configurations in which no to-be-reported beam is reported.

[0302] In this case, the network device can further receive third indication information from the terminal device through the first uplink channel.

[0303] In some embodiments, the third indication information can be included in the first beam report, that is, the third indication information can be subordinate to the first beam report.

[0304] In some embodiments, the third indication information can be information other than the first beam report, that is, the third indication information can be in a parallel relationship with the first beam report.

[0305] Optionally, the third indication information can indicate the number of beam reporting configurations in which no to-be-reported beam is reported.

[0306] It is easy to understand that the network device can know the number of beam reporting configurations in which no to-be-reported beam is reported through the third indication information, which is beneficial to determine whether to schedule for the beam reporting configuration in which no to-be-reported beam is reported in the future, to obtain the beam measurement result of the to-be-reported beam corresponding to the beam reporting configuration, and thus to help the network device make a decision on resource configuration (for example, regarding handover, handover, etc.) of the terminal device.

[0307] Optionally, the third indication information can indicate the number of to-be-reported beams that are not reported.

[0308] It is easy to understand that the network device can learn the number of the unreported to-be-reported beams through the third indication information, which is beneficial to determining whether to schedule the unreported to-be-reported beams in the future to obtain the beam measurement results of the to-be-reported beams, thereby facilitating the network device to make a decision on resource configuration (e.g., regarding handover, handoff, etc.) of the terminal device.

[0309] Further, in some embodiments, the method further includes: sending, to the terminal device, fourth indication information, the fourth indication information indicating a second uplink channel; and receiving, from the terminal device, a second beam report through the second uplink channel based on the fourth indication information, wherein the second beam report includes beam quality of the unreported to-be-reported beams.

[0310] After the terminal device sends the first beam report and the third indication information to the network device, the network device can determine, according to the third indication information, that there is still unreported to-be-reported beam information on the terminal device side. If the network device wants to obtain the related information (e.g., beam quality) of the unreported to-be-reported beams, the network device can send fourth indication information to the terminal device to schedule a second uplink channel to let the terminal device report the related information of the unreported to-be-reported beams to the network device. The network device can determine the number of unreported to-be-reported beams based on the third indication information, thereby being able to determine appropriate time-frequency resources for the second uplink channel.

[0311] Optionally, the fourth indication information can be a DCI, which schedules the second uplink channel.

[0312] Optionally, the second uplink channel can be a PUSCH.

[0313] It is easy to understand that the network device schedules the unreported to-be-reported beams, which can obtain the beam measurement results of the previously unreported to-be-reported beams, thereby facilitating the network device to comprehensively evaluate the communication environment of the terminal device and making a more accurate decision on resource configuration (e.g., regarding handover, handoff, etc.) of the terminal device.

[0314] Alternatively, in some embodiments, the method further includes: sending, to the terminal device, fifth indication information, the fifth indication information being used to indicate that the first beam report is correctly received.

[0315] After the terminal device sends the first beam report (and the third indication information) to the network device, the network device can determine, according to the first beam report (and the third indication information), that there is no unreported beam information on the terminal device side (in this case, the third indication information can be empty or indicate a number of 0). The network device can send fifth indication information to the terminal device to indicate that the first beam report is correctly received.

[0316] Optionally, the fifth indication information can be DCI that does not schedule an uplink channel.

[0317] Optionally, the fifth indication information can be acknowledgement information, for example, ACK information.

[0318] Alternatively, in some embodiments, the method further includes: based on the first beam report not being correctly received, continuing to monitor the uplink channel to receive the first beam report sent again by the terminal device.

[0319] After the terminal device sends the first beam report (and the third indication information) to the network device, if the network device does not correctly receive the first beam report, the network device will not send the fourth indication information and the fifth indication information to the terminal device. The terminal device can send the first beam report again to the network device through the first uplink channel based on not receiving the fourth indication information and the fifth indication information from the network device.

[0320] It is easy to understand that the network device sending the acknowledgement indication to the terminal device, and the terminal device repeatedly sending the first beam report to the network device, are beneficial to guarantee the reliability of transmission through the uplink channel, and are beneficial to guarantee the correct transmission of the first beam report.

[0321] It can be found that, based on the method of the present application, by determining the maximum load of the beam report based on the first indication information, the resource overhead required for the first uplink channel for transmitting the beam report can be controlled, excessive uplink channel resources can be avoided due to too many beams needing to be reported to meet the triggering condition, and excessive waste of the pre-configured uplink channel resources can also be avoided due to too few beams needing to be reported to meet the triggering condition.
