Description

Communication method, communication apparatus, and related device

[0001] This application claims priority to the Chinese patent application No. 202411341709.8, filed on September 24, 2024, and entitled "A communication method, a communication apparatus and related device", the content of which is incorporated herein by reference in its entirety. TECHNICAL FIELD

[0002] The present application relates to the field of communication technology, and in particular to a communication method, a communication apparatus and related device. BACKGROUND

[0003] A communication system refers to a system for wireless communication, which can include network devices such as base stations, each of which can support communication with multiple terminal devices. A terminal device can be a user equipment (UE). The terminal device is configured to detect beam information, such as beam quality, reference signal strength, or beam direction, and send the detected beam information to the network device. The network device adjusts the beam direction or obtains a set of beam configurations that provide the best call quality based on the beam information, to determine high reliability and low latency of communication, etc.

[0004] According to the specification of the 3rd Generation Partnership Project (3GPP), the terminal device reports the beam information to the network device side when the terminal device detects that the beam information satisfies a specific event type. The specific event type includes but is not limited to the following events: a first event type (also referred to as Event-1), a second event type (also referred to as Event-2), and a third event type (also referred to as Event-7). The satisfaction condition of Event-1 is that the quality of the current beam is lower than a first threshold value. This indicates that the quality of the current beam is starting to deteriorate, and a warning needs to be sent to the network device side to decide whether to perform beam switching or beam adjustment to improve the communication quality. The satisfaction condition of Event-2 is that at least one new beam is found, wherein the beam quality of the new beam is greater than the sum of the current beam quality and a second threshold value. The satisfaction condition of Event-7 is that the quality of at least one new beam is greater than the sum of the quality of the last beam in the top n1 beams in the signal quality of the currently activated Transmission Configuration Indication State (TCI State) and a third threshold value. Wherein n1 is an integer greater than or equal to 1.

[0005] However, at present, the beam report sent by the terminal device to the network device does not contain the event type corresponding to the beam report, which makes the network device unable to determine the event type corresponding to the received beam report. Moreover, when the terminal device transmits multiple beam reports, the terminal device cannot solve the multiplexing conflict problem between the event-related beam report and the existing uplink control signaling, which affects the effect of the network device adjusting the beam direction or hinders the network device from obtaining the beam configuration with the best call quality, thereby affecting the communication quality. SUMMARY

[0006] The present application provides a communication method, a communication device and related equipment, which are used to make the network device determine the event type corresponding to the received beam report, and make the terminal device solve the problem of being unable to process the event-related beam report and solve the multiplexing conflict problem of the existing uplink control signaling when transmitting multiple beam reports, improve the effect of the network device adjusting the beam direction and obtain the beam configuration with the best call quality, thereby improving the communication quality.

[0007] In a first aspect, an embodiment of the present application provides a communication method applied to a terminal device. The method specifically includes: if a first available transmission opportunity, a beam report associated with an event to be sent is associated with n events, based on channel state information report (CSI report) priority values of the n events, a first beam report is sent. The first beam report includes measurement values of reference signals of all or part of events in the n events. The CSI report priority value of the event is related to the event type priority of the event. The higher the event type priority of the event is, the smaller the priority value of the CSI report of the event is. The event type priority indicates the priority of the beam report associated with the event. The lower the priority of the beam report associated with the event is, the lower the event type priority is, and the later the beam report associated with the event is reported to the network device side.

[0008] If the first available transmission occasion, the beam report associated with the event to be sent is associated with one event, and the one event is the first event type, the second beam report is sent, and the second beam report includes the measurement value of the reference signal of the first event type, and the measurement value of the reference signal refers to the differential value of the layer one reference signal received power (L1-RSRP) or the differential value of the layer one signal-to-interference-plus-noise ratio (L1-SINR) of the reference signal (RS) associated with the indicated transmission configuration indicator state (indicated TCI state).

[0009] Exemplarily, in 5G communication, the event-associated beam report is the CSI report of the event. The event-associated beam report reported on the first available transmission occasion includes the first event, the second event, and the third event. If the event type priority of the first event is higher than the event type priority of the second event, and the event type priority of the second event is higher than the event type priority of the third event, it can be determined that the CSI report priority value of the first event is less than the CSI report priority value of the second event, and the CSI report priority value of the second event is less than the CSI report priority value of the third event. That is, the priority of the beam report associated with the first event is higher than the priority of the beam report associated with the second event, and is higher than the priority of the beam report associated with the third event. Therefore, in the face of the multiplexing conflict problem that the terminal device cannot process the beam report associated with the event and the existing uplink control signaling, the terminal device can select the beam report of the event with a low CSI report priority value to send, so that the network device can receive the beam report associated with the event with a high priority with a higher probability, and then adjust the beam direction or obtain the beam configuration with the best call quality according to the beam report associated with the event with a high priority, thereby improving the communication quality. Further, the network device can determine the event type corresponding to the beam report based on the CSI report priority value of the m events in the beam report. For example, by comparing the CSI report priority value of the event with the CSI report priority value of the known event type, the event type corresponding to the beam report is determined.

[0010] In addition, if the event-associated beam report is associated with one event, and the one event is the first event type, i.e., Event-1, the measurement value of the RS sending the Event-1 is transmitted, specifically, the L1-RSRP difference value or the L1-SINR difference value of the RS associated with the indicated TCI state. Thus, the network device can determine whether the event type of the beam report is Event-1 according to the measurement value of only one RS in the beam report.

[0011] In an example, the measurement value of the RS is a difference value with a bit width of 4 bits, i.e., the network device can determine whether the event type of the beam report is Event-1 according to the measurement value of only one RS in the beam report, and the measurement value is a difference value with a bit width of 4 bits. In another example, the beam report only contains the L1-RSRP difference value or the L1-SINR difference value with a bit width of 4 bits, and the event type of the beam report is Event-1.

[0012] In summary, the communication method provided by the embodiments of the present application can determine the first beam report by using the CSI report priority value related to the event type priority of the event when the event-associated beam report to be transmitted at the first available transmission opportunity is associated with multiple events, transmit the first beam report, and transmit the second beam report when the event-associated beam report to be transmitted at the first available transmission opportunity is associated with one event and the event type is the first event type. The second beam report includes the measurement value of the RS of Event-1. Thus, the network device can determine the event type corresponding to the received beam report, and the terminal device can solve the problem of being unable to process the event-associated beam report and the multiplexing conflict of the existing uplink control signaling when transmitting multiple beam reports, improve the effect of the network device adjusting the beam direction, and obtain the best beam configuration for the call quality and improve the communication quality.

[0013] The first available transmission opportunity refers to the first available transmission opportunity corresponding to Mode A and / or the first available transmission opportunity corresponding to Mode B. That is, the communication method provided by the embodiments of the present application can be used in Mode A and / or Mode B. That is, before transmitting the beam report on the second uplink channel, the UE can determine the event-associated beam report and / or other CSI report to be transmitted based on the event-associated beam report to be transmitted or based on the event-associated beam report to be transmitted and other CSI reports.

[0014] In a specific implementation, if the beam report associated with the event to be sent by the first available transmission opportunity is associated with one event, and the event type is the second event type or the third event type, a third beam report is sent, wherein the third beam report includes first identification information indicating the second event type or the third event type. For example, the first identification information is Event-7 or Event-2. In this way, the network device can distinguish whether the event type corresponding to the beam report is Event-2 or Event-7 based on the first identification information in the third beam report, i.e., the identification information of Event-2 or Event-7.

[0015] In some specific embodiments, the first identification information occupies a bit width of 1 bit.

[0016] In some specific embodiments, the determination method of the first available transmission opportunity associated with multiple events includes: if the beam reports of the n events reported overlap in the time domain, or exist simultaneously in at least one time slot, the time window of the event is enabled after the reporting of one event, and the time window of the other event is enabled before the completion of the event triggering, it is determined that the beam report reported in the first available transmission opportunity is associated with n events, and N1 is an integer greater than 1.

[0017] In another specific implementation, the CSI report priority value is related to the value of the report configuration identifier (reportConfigID), the value of the reportConfigID is related to the priority of the corresponding event, the higher the priority of the corresponding event, the smaller the value of the reportConfigID, the smaller the CSI report priority value, and the higher the priority of the beam report of the corresponding event, which is determined to be sent to the network device first. That is, by reporting the beam report of the high-priority event first, it is ensured that the high-priority event can be processed faster. By processing the high-priority event first, the allocation of network resources is optimized. The report configuration of the high-priority event is arranged in the front, which can reduce the processing delay.

[0018] The network device can configure the priority of the event type of the terminal device, and the terminal device can also configure the priority of the event type itself. In one implementation, if the value of the reportConfigID corresponds to an event of a first event type, the first event type has the highest priority, i.e., the priority of the corresponding event is higher than the priority of a second event type and the priority of a third event type. In another specific implementation, the priority of the second event type is higher than the priority of the third event type.

[0019] In another implementation, the CSI report priority value is related to a priority of a type of event indicated by the first channel indication, and the higher the priority of the type of event indicated by the first channel indication, the smaller the CSI report priority value. In this way, by establishing a correspondence between the CSI report priority value and the type of event, the network device can determine the CSI report priority value based on the order of reporting of the beams, and then distinguish the types of events.

[0020] In yet another implementation, if the number of bits occupied by the beam reports associated with the n events exceeds the upper limit of PRB transmission that can be carried by the preconfigured resource notified by the first channel indication, m events are determined from the n events based on the CSI report priority values of the n events, the number of bits occupied by the beam reports associated with the m events is less than or equal to the upper limit of PRB transmission that can be carried by the preconfigured resource notified by the first channel indication,

[0021] Or, if the sum of the number of bits occupied by the beam reports associated with the n events and the number of bits occupied by other multiplexed uplink control signaling exceeds the upper limit of PRB transmission that can be carried by the preconfigured resource notified by the first channel indication, m events are determined from the n events based on the CSI report priority values of the n events, the sum of the number of bits occupied by the beam reports associated with the m events and the number of bits occupied by other multiplexed uplink control signaling is less than or equal to the upper limit of PRB transmission that can be carried by the preconfigured resource notified by the first channel indication.

[0022] And the CSI report priority value of the m events is higher than the CSI report priority value of the remaining n-m events. That is, the terminal device discards the beam reports of the remaining n-m events and only sends the beam reports of the determined m events. In this way, it can be ensured that the beam reports associated with events with higher priority can be reported to the network device in priority, thereby improving the communication quality.

[0023] The priority of the event-related beam report is lower than the priority of an L1 / L2-triggered mobility (LTM) beam report and higher than the priority of other beam reports, or the priority of the event-related beam report is higher than the priority of other beam reports including the LTM beam report. The event-related beam report is triggered by one or more of a first event type, a second event type, or a third event type. Such a beam report includes key information of beam quality change, and thus needs to be set with a high beam report priority. The LTM beam report involves measurement of a medium access control layer and a radio link control layer, and is crucial for determining the reliability of data transmission. Therefore, the priority of the event-related CSI report is higher than the priority of other CSI reports. The other CSI reports refer to other beam reports other than the event-related CSI report and the LTM CSI report.

[0024] In another specific implementation, if the n events include the second event type, the first beam report includes an L1-RSRP differential value or an L1-SINR differential value of an indicated TCI state-related RS of the second event type.

[0025] In yet another specific implementation, if the n events include the first event type, the first beam report includes a measurement value of an RS indicating the first event type. By reporting only the L1-RSRP differential value of one event, the reporting content is simplified, and the amount of transmission data is reduced.

[0026] If the n events include n2 events, the n2 events have the same measurement information and measurement results, and based on the first beam information of the n events, a first beam report of m events of the n events is sent according to a CSI report priority value, the first beam report includes beam information after merging of n1 events and indication information indicating merging of n2 events, and n2 is an integer greater than 1. By merging the L1-RSRP differential values of the current beams of multiple events, the transmission of repeated data can be reduced, and the transmission efficiency is improved.

[0027] In a second aspect, an embodiment of the present application provides a communication method applied to a network device, and the method comprises the following steps:

[0028] receiving the first beam report or the second beam report; parsing the received first beam report to obtain a CSI report priority value of m events in the first beam report, the CSI report priority value of the event decreasing with an increase of an event type priority of the event, and the CSI report priority value of the event decreasing with an increase of a priority of a beam report associated with the event, m being greater than or equal to 0; or parsing the received second beam report to obtain a measurement value of an RS indicating a first event type, the measurement value of the RS referring to a L1-RSRP differential value or a L1-SINR differential value of an RS indicating a TCI state.

[0029] In a specific implementation, the third beam report is received; and the third beam report is parsed to obtain first identification information indicating the second event type or the third event type.

[0030] The CSI report priority value is related to a value of a report configuration identifier reportConfigID, and the value of the reportConfigID decreases with an increase of a priority of a corresponding event.

[0031] In another specific implementation, the network device configures the priority of the event, the priority of the event including that the priority of the first event type is higher than the priority of the second event type, and the priority of the first event type is higher than the priority of the third event type.

[0032] In yet another specific implementation, the CSI report priority value decreases with an increase of the priority of the event type of the first channel indication.

[0033] In a third aspect, an embodiment of the present application provides a communication device applied to a terminal device, the device comprising:

[0034] The sending unit is configured to send the first beam report based on the CSI report priority values of the n events if the beam report associated with the event to be sent at the first available transmission opportunity is associated with the n events, the first beam report including m events of the n events, n being an integer greater than 0, m being an integer greater than 0, n being greater than or equal to m, and the CSI report priority value of the event decreasing with an increase of an event type priority of the event.

[0035] The sending unit is configured to send the second beam report if the beam report reported at the first available transmission opportunity is associated with one event, and the one event is of the first event type, the second beam report including a measurement value of an RS of the first event type, the measurement value of the RS referring to a L1-RSRP differential value or a L1-SINR differential value of an RS indicating a TCI state.

[0036] In a fourth aspect, an embodiment of the present application provides a communication apparatus, characterized in that the apparatus comprises:

[0037] a receiving unit configured to receive the first beam report or the second beam report; and a parsing unit configured to parse the first beam report to obtain beam information of m events in the first beam report, the m events being arranged in order of CSI report priority values, m being an integer greater than 0; or parse the second beam report to obtain a measurement value of an RS indicating a first event type, the measurement value of the RS referring to a differential value of L1-RSRP or a differential value of L1-SINR of the RS associated with an indicated TCI state.

[0058] FIG. 1 shows a structure of a communication system according to an embodiment of the present application. The communication system includes a network device 102 and a terminal device 101. The network device 102 is a device for providing network communication functions, and is also called a network element in some cases. The network device 102 can be a base station, a function unit of the base station, or a ground network device 102.

[0059] In the embodiments provided by the present application, the base station can be any device with wireless transceiving function, including but not limited to: an evolved base station (NodeB or eNB or e-NodeB, evolutional Node B) in long term evolution (LTE), a base station (gNodeB or gNB) or a transmission receiving point (TRP) in new radio (NR), a base station in subsequent evolution of 3GPP, an access node in Wi-Fi system, a wireless relay node, a wireless backhaul node, etc. The base station can be: a macro base station, a micro base station, a pico base station, a small station, a relay station, or a balloon station, etc. The base station can include one or more co-sited or non-co-sited transmission points (TRPs). The base station can also be a wireless controller in a cloud radio access network (CRAN) scenario, a centralized unit (CU), and / or a distributed unit (DU).

[0060] In the embodiments provided in the present application, the terminal device 101 can be a device providing voice or data connectivity for a user, such as a mobile phone, a tablet computer, a computer with wireless transceiver function, a virtual reality (VR) terminal device 101, an augmented reality (AR) terminal device 101, a wireless terminal device 101 in industrial control, a vehicle-mounted terminal device 101, a wireless terminal device 101 in self driving, a wireless terminal device 101 in remote medical treatment, a wireless terminal device 101 in smart grid, a wireless terminal device 101 in transportation safety, a wireless terminal device 101 in smart city, a wireless terminal device 101 in smart home, a wearable terminal device 101, and the like. The terminal device 101 can also be referred to as a terminal device 101, a user equipment (UE), an access terminal device 101, a vehicle-mounted terminal device 101, an industrial control terminal device 101, a UE unit, a UE station, a mobile station, a mobile station, a remote station, a remote terminal device 101, a mobile device, a UE terminal device 101, a terminal device 101, a wireless communication device, a UE agent, or a UE apparatus, and the like. The terminal device 101 can also be a fixed terminal device 101 or a mobile terminal device 101.

[0061] The base station can communicate with the terminal device 101, or can communicate with the terminal device 101 through a relay station. The terminal device 101 can communicate with multiple base stations of different technologies, for example, the terminal device 101 can communicate with a base station supporting an LTE network, or can communicate with a base station supporting a 5G network, or can communicate with a base station supporting an LTE network and a base station supporting a 5G network in dual connectivity. To improve the communication quality of the base station and the terminal device 101, the terminal device 101 detects beam information, such as beam quality, reference signal strength, or beam direction, and sends the detected beam information to the network device 102. The network device 102 adjusts the beam direction or obtains a set of beam configurations providing the best communication quality based on the beam information, so as to improve the high reliability and low delay of the communication between the terminal device 101 and the network device 102.

[0062] According to the specification of 3GPP, when the terminal device 101 detects that the beam information meets the threshold condition of at least one of the first event type, the second event type, or the third event type, the terminal device 101 reports the beam information to the network device 102.

[0063] In one implementation, the beam information includes beam indices of the N candidate beams, a measurement value of the RS, measurement values of the other candidate beams, and a measurement value of the current beam. In one example, the measurement value of the RS can be a L1-RSRP differential value or a L1-SINR differential value. The measurement values of the other candidate beams are L1-RSRP differential values or L1-SINR differential values of the candidate beams. The measurement value of the current beam is a L1-RSRP differential value or a L1-SINR differential value of the current beam. Wherein N is an integer greater than or equal to 2.

[0064] Wherein, through the beam indices of the candidate beams, the base station can uniquely identify the candidate beams corresponding to the candidate beam indices. In one specific example, the beam indices of the N candidate beams can be Channel State Information-Reference Index (CRI) or Synchronization Signal Block Reference Index (SSBRI), for example, the beam index corresponding to candidate beam 1 is CRI or SSBRI#1, the beam index corresponding to candidate beam 2 is CRI or SSBRI#2, and so on.

[0065] The beam corresponding to the RS is the beam with the maximum RSRP value in the N candidate beams, that is, the beam with the maximum L1-RSRP absolute value, or the beam with the maximum SINR value in the N candidate beams, that is, the beam with the maximum L1-SINR absolute value. For example, the beam corresponding to the reference signal is candidate beam 1 corresponding to beam index CRI or SSBRI#1, wherein candidate beam 1 is the beam with the maximum L1-RSRP absolute value in the N candidate beams.

[0066] The L1-RSRP differential value of the other candidate beam is determined by the difference between the L1-RSRP measured by the other candidate beam and the L1-RSRP value of the RS. The L1-SINR differential value of the other candidate beam is determined by the difference between the L1-SINR measured by the other candidate beam and the L1-SINR value of the RS.

[0067] The terminal device 101 reduces the signaling size by transmitting the L1-RSRP or L1-SINR of the RS and the L1-RSRP differential value or L1-SINR of the other beam, thereby reducing the transmission overhead.

[0068] The differential value of L1-RSRP of the current beam is determined by the L1-RSRP value of the current beam and the RS. The differential value of L1-SINR of the current beam is determined by the difference between the L1-SINR value of the current beam and the RS. Therefore, the signaling size can be reduced, and the transmission overhead can be reduced.

[0069] In a specific implementation, the terminal device 101 can report the beam information to the network device 102 through the format of the beam report as shown in Table 1. The beam information shown in Table 1 includes the beam indexes CRI or SSBRI#1-CRI or SSBRI#N of the N candidate beams. The beam information further includes the beam information L1-RSRP#1 of the RS, which is the RSRP value with the largest measured value among all the RSRP values of the RS, and is the absolute value of L1-RSRP.

[0070] In addition, the beam information further includes the differential values (i.e., Differential L1-RSRP#2-L1-RSRP#N) of L1-RSRP#2-L1-RSRP#N. The differential values L1-RSRP#2-L1-RSRP#N are determined by the difference between the L1-RSRP value corresponding to CRI / SSBRI#2-#N and the L1-RSRP value corresponding to CRI / SSBRI#1. Further, the beam information further includes the differential value of L1-RSRP of the current beam, which is determined by the difference between the L1-RSRP value of the current beam and the L1-RSRP value of CRI / SSBRI#1.

[0071] Table 1

[0072] Further, when the terminal device 101 reports the beam information through the beam report, it also needs to follow the preset encoding rule. The preset encoding rule is used to limit the bit width (i.e., Bitwidth) of the reported quantity. For example, Table 2 and Table 3 define the Bitwidth that needs to be met for the quantity that needs to be reported. Table 2 corresponds to the Bitwidth of CRI, SSBRI, RSRP, differential RSRP, and capability index, and Table 3 corresponds to the Bitwidth of CRI, SSBRI, SINR, differential SINR, and capability index.

[0073] Table 2

[0074] Table 3

[0075] The Bitwidth of CRI is wherein, is a ceiling symbol, is the number of Channel State Information-Reference Signal (CSI-RS) resources associated with index S in the corresponding resource set. indicates the number of Synchronization Signal / Physical Broadcast Channel (SS / PBCH) blocks associated with index S in the corresponding resource set for reporting RSRP related to a specific Synchronization Signal Block (SSB) index, i.e., reporting "SSB-index-RSRP".

[0076] One beam report is used to report the measurement value of a beam, and the mapping order of the domain used to report the measurement value of the beam. For example, in a 5G communication system, the beam report sent by the terminal device 101 is a Channel State Information Report (CSI report), and the CSI report reports the mapping order of the RSRP or SINR domain. Thus, the network device 102 can obtain beam information based on the mapping order of the domain of the beam measurement value reported by the beam report, and perform beam updating and beam measurement according to the beam information.

[0077] However, the beam report sent by the terminal device 101 to the network device 102 does not consider the format change of the beam report triggered by different event types, which causes the network device 102 to be unable to determine the event type satisfied by the received beam information. Moreover, when the terminal device 101 transmits multiple beam reports, uplink control information collision or limited uplink physical resources may occur, which causes the beam report to be unable to be accurately sent to the network device 102, affecting the accuracy of the network device 102 adjusting the beam direction or obtaining the best beam configuration of the call quality, thereby affecting the communication quality.

[0078] Based on the above problems, the embodiment of the present application provides a communication method. When a beam report associated with multiple events is reported on a first available transmission occasion, a CSI report priority value related to an event type priority of the event is used to determine a first beam report, the first beam report is sent, and when the beam report is associated with one event on the first available transmission occasion and the event type is a first event type, a measurement value of a RS of Event-1 is included in a second beam report, and the event type corresponding to the beam report is sent to a network device. Therefore, the network device can determine the event type corresponding to the received beam report, and the terminal device can improve the effect of the network device adjusting the beam direction and obtain the best beam configuration for the call quality in the case of uplink control information conflict or limited uplink transmission resources, thereby improving the communication quality.

[0079] The communication method provided by the embodiment of the present application is described in detail below with reference to the accompanying drawings. For convenience of description, the measurement value of the beam is L1-RSRP in the following description, and in actual use, the measurement value of the beam can also be L1-RSRP differential value, L1-SINR, L1-SINR differential value, etc. Since the communication principle is the same as L1-RSRP, it is not described here. The beam report associated with the event is also called CSI report of the event.

[0080] FIG. 2 is a flowchart of a communication method provided by the embodiment of the present application, which is applied to the communication system shown in FIG. 1, and the method includes the following contents.

[0081] In S210, the terminal device 101 determines whether the reported beam report is associated with multiple events. If the beam report is associated with multiple events, S220 is performed, and if the beam report is associated with only one event, S240 is performed.

[0082] The terminal device 101 determines whether the beam report reported to the network device 102 on the first available transmission occasion is associated with multiple events. It can be understood that if the beam report is associated with multiple events, uplink control information conflict or uplink physical resource limitation occurs, which causes the beam report to be unable to be accurately sent to the network device 102. Based on the above problem, first, the terminal device 101 determines whether the beam report reported to the network device 102 on the first available transmission occasion is associated with multiple events.

[0083] In an example, the first available transmission occasion can be Mode B of the transmission process of the beam report initiated / triggered by the UE, and the first transmission occasion available for sending the second uplink channel beam report is after X symbols after the last symbol of the first channel indication.

[0084] wherein X is an integer and X≥0. Mode B is one of the UE-initiated / triggered beam reporting transmission procedures, in which the first channel indication is used to notify the network device, and the UE transmits the beam report on the second uplink channel using the pre-configured resource. In some embodiments, the first channel indication occupies a bitwidth of 1 bit, and the first channel indication is associated with one or more pre-configured resources. A symbol is the minimum time unit in a slot.

[0085] For example, if the first channel indication occupies the first 3 symbols of the target slot, X = 2, the terminal device 101 uses the first 3 symbols of the target slot to transmit the first channel indication, the last symbol of the first channel indication is the third symbol, and the terminal device 101 waits for 2 symbols after the third symbol, i.e., until the end of the fifth symbol, and then starts the sixth symbol. The first available transmission occasion that satisfies the periodicity and offset constraint rules of the CSI report configuration is the first available transmission occasion.

[0086] Mode A is another mode of the UE-initiated / triggered beam reporting transmission procedure, which is different from Mode B. In Mode A, the first channel indication is used to request resources for transmitting the beam report from the network device, and the network device 101 transmits the resource indication for the beam report to the UE through downlink signaling before the UE initiates the beam report.

[0087] In another example, the first available transmission occasion can also be the first available transmission occasion corresponding to Mode B and the first available transmission occasion corresponding to Mode A of the UE-initiated / triggered beam reporting transmission procedure.

[0088] In summary, the communication method provided by the embodiments of the present application can be used for the first available transmission occasion corresponding to Mode A and / or the first available transmission occasion corresponding to Mode B. That is, before transmitting the beam report on the second uplink channel, the UE can determine the event-associated beam report and / or other CSI report to be transmitted based on the 1 or more event-associated beam reports to be transmitted or based on the 1 or more event-associated beam reports to be transmitted and other CSI reports.

[0089] In the embodiments of the present application, the terminal device 101 can determine whether the beam report reported to the network device 102 at the first available transmission occasion is associated with multiple events in the following manner. If the reported events satisfy at least one of the following conditions within the first available transmission occasion, it is determined that the beam report reported to the network device 102 at the first available transmission occasion is associated with multiple events:

[0090] Condition 1: n event-associated beam reports are reported, and the n event-associated beam reports overlap in time domain, and / or the n event-associated beam reports exist simultaneously in at least one time slot. Condition 2: after reporting one event-associated beam report, other event-associated beam reports are reported within m1 time slots, where m1 is an integer greater than 1. Condition 3: after enabling the time window of reporting one event-associated beam report and before the event triggering is completed, the time window of reporting other event-associated beam reports is enabled.

[0091] For example, if the n events include a first event type, a second event type, and a third event type, Condition 1 is that the terminal device 101 determines that the second event type or the third event type overlaps with the beam report resource reported by the first event type in time domain, and / or the first event type, the second event type, and the third event type exist simultaneously within m2 time slots, where m2 is an integer greater than or equal to 1. Condition 2: after the terminal device 101 reports the first channel indication of the first event type, the first channel indication of the second event type and / or the third event type is reported within m1 time slots. Condition 3: after the time window (i.e., Time Window) of the beam report associated with the first event type is enabled, the time window of the beam report associated with the second event type and / or the third event type is enabled before the event triggering is completed, and the second event type and / or the third event type is triggered within m3 time slots after the beam report associated with the first event type is triggered, where m3 is an integer greater than 0.

[0092] In addition, the terminal device 101 can also determine whether the beam reports to be reported overlap by other conditions, which are not specifically limited in the embodiments of the present application.

[0093] S220, the terminal device 101 determines the beam report priority values of n events, and determines m event-associated beam reports from the n event-associated beam reports.

[0094] The n events are a plurality of events to be transmitted by the terminal device 101 in the first available transmission opportunity, and n is an integer greater than 1.

[0095] The beam report priority value is used to determine the order of reporting the beam report. The lower the beam report priority value, the higher the priority of the corresponding beam report, and the more priority the beam report has to be reported to the network device 102. For example, in a 5G communication system, the beam report is a CSI report, and the beam report priority value is a CSI report priority value used to determine the order of reporting the CSI report. The lower the CSI report priority value, the higher the priority of the CSI report, and the more priority the CSI report has to be reported to the network device 102.

[0096] In the embodiments of the present application, the beam report priority value is used to indicate the event type, and different event types correspond to different beam report priority values. For example, if the event type is Event-2, the beam report priority value is a first value, if the event type is Event-7, the beam report priority value is a second value, and if the event type is Event-1, the beam report priority value is a third value, wherein the first value is less than the second value, and the second value is less than the third value, that is, Event-2 is preferentially reported.

[0097] In an example, the beam report corresponding to the event type is associated with the corresponding reportConfigID in the order of priority from high to low and the value s of reportConfigID from small to large. In this way, the higher the priority of the event type (the priority of the beam report corresponding to the event type), the smaller the s of the associated reportConfigID, the smaller the CSI report priority value, and the higher the CSI report priority. That is, by preferentially reporting high-priority events, high-priority events can be processed faster. By preferentially processing high-priority events, the allocation of network resources is optimized. The report configuration of the high-priority event is arranged in the front, which can reduce the processing delay. The priority of the event can be configured by the network device 102 or pre-configured by the terminal device 101.

[0098] For the Event-2, Event-7 and Event-1 provided in the embodiments of the present application, the priority of the event type can be configured as Event-2>Event-7>Event-1, or Event-2>Event-1>Event-7, that is, the beam report of the most critical event Event-2 is preferentially transmitted and processed, so as to ensure that the communication quality is not affected, and through the priority sorting, the beam report transmission conflict of the event can be avoided.

[0099] In another example, the CSI report priority value is related to the serving cell index (i.e., serving cell index) in addition to the value of reportConfigID. The serving cell index is usually arranged in a certain order from large to small or from small to large. The principle of the sorting configuration of the serving cell ID is to set the value of the reportConfig of the high-priority event in a smaller serving cell, that is, to set the high-priority event in a serving cell with a smaller service index. Among them, the smaller serving cell refers to a cell with a service cell index smaller than a preset threshold.

[0100] For example, in one specific scenario, three serving cells are included, with serving cell indexes 0, 1 and 2 respectively, wherein the serving cell with index 0 has the highest priority, and the serving cell with index 2 has the lowest priority. The terminal device 101 places Event-2 in the serving cell with index 0. In this way, it is ensured that the high-priority event is processed first, thereby optimizing resource utilization.

[0101] In one specific example, the CSI report priority value Pri iSSI (y, k, c, s) = 2N cells M s y+N cells M s k+M s k+M s c+s (1)

[0102] wherein Pri iCSI (y, k, c, s) is the CSI report priority value, and s is the reportConfigID value. y = 0 represents an aperiodic CSI report carried by a physical uplink shared channel (PUSCH); y = 1 represents a semi-persistent CSI report carried by a PUSCH; y = 2 represents a semi-persistent CSI report carried by a physical uplink control channel (PUCCH); y = 3 represents a periodic CSI report carried by a PUCCH; k = 0 represents that the CSI report carries L1-RSRP or L1-SINR; k = 1 represents that the CSI report does not carry L1-RSRP or L1-SINR. c is a serving cell index, Ncells is the value of the higher-layer parameter maxNrofServingCells, and Ms is the value of the higher-layer parameter maxNrofCSI-ReportConfigurations.

[0103] The determination manner of the CSI report priority value shown in formula (1) can distinguish the CSI report priority values of different events, and further distinguish the priorities of the CSI reports of different events.

[0104] It should be noted that the value of the above-mentioned 1 reportConfig is only associated with 1 event type, or when 1 reportConfig is associated with multiple event types, 1 specific event type in the associated multiple event types is indicated by the network device.

[0105] In yet another implementation, the value of the event type e indicated by the first channel is associated with the priority of the event type. The higher the priority of the event type, the smaller e is, and the smaller the beam report priority value is.

[0106] For example, the determination of the CSI report priority value is shown in formula (2). Wherein, Pri iCSI (y, k, c, s, e) = 2N cells M s y+N cells M s k+M s k+M s c+s+e (2)

[0107] For example, if the priority order of the event type is: Event-2>Event-7>Event-1, and the corresponding e values are 0, 1, 2, or -2, -1, 0 in order, respectively. Thus, different event types can be distinguished based on the CSI report priority value.

[0108] The embodiments of the present application can also determine the report priority value corresponding to each event type in other ways, which are not specifically limited in the embodiments of the present application.

[0109] The terminal device 101 can send the beam report associated with the n to-be-sent events to the network device.

[0110] In another implementation, since the upper limit of the physical resource block (PRB) transmission transmitted by the terminal device 101 to the network device 102 is fixed, if the number of bits of the transmitted beam report exceeds the upper limit of the PRB transmission that the preconfigured resource indicated by the first channel can carry, or the sum of the number of bits occupied by the transmitted beam report and the number of bits occupied by other multiplexed uplink control signaling exceeds the upper limit of the PRB transmission that the preconfigured resource indicated by the first channel can carry, the transmission quality will be affected. Wherein, the upper limit of the PRB transmission is the upper limit of the number of bits that the resource used by the terminal device 101 to carry the uplink control signaling in the current time slot can carry.

[0111] Therefore, based on the above problems, the terminal device 101 can determine whether the total number of bits of the transmitted beam report of the n events exceeds the PRB transmission upper limit that the preconfigured resource notified by the first channel indication can carry, or the sum of the number of bits occupied by the beam report and the number of bits occupied by other multiplexed uplink control signaling exceeds the PRB transmission upper limit that the preconfigured resource notified by the first channel indication can carry. If it exceeds, m events are selected from the n events, the total number of bits of the beam report associated with the m events is less than or equal to the PRB transmission upper limit, and to ensure communication quality, the priority value of the CIS report of the m events is lower than the CSI report priority value of the remaining n-m events. The first beam report includes the beam report of the m events, and the remaining n-m beam reports are discarded. Wherein, m is an integer greater than or equal to 0 and less than or equal to n. In this way, the total number of bits of the transmitted first beam report can be ensured to be less than or equal to the PRB transmission upper limit, and the event with higher priority is ensured to be transmitted first, thereby ensuring the communication quality.

[0112] Example: If the content corresponding to each event type is distinguished according to a predefined bit interval, if there are event-a, event-b, and event-c with priority from high to low, and the bit number of the CSI exceeds the transmission PRB transmission upper limit, and the bit number of the CSI of event-a and event-b is less than or equal to the transmission PRB upper limit, then all bits corresponding to event-c are discarded. In this way, on the basis of ensuring the communication quality of the terminal device 101 and the network device 102, the transmission signaling overhead is reduced and the transmission quality is improved.

[0113] Further, if the beam report is a CSI report, the priority of the CSI report associated with the event is lower than the priority of the LTM CSI report and higher than the priority of other CSI reports. Or the priority of the CSI report associated with the event is higher than the priority of the LTM CSI report and the priority of other CSI reports.

[0114] Wherein, the CSI report associated with the event is the beam report triggered by the first event type, the second event type or the third event type, such beam report involves key information of network switching, therefore, high CSI report priority needs to be set. The LTM beam report involves measurement of the medium access control layer and the wireless link control layer, which is crucial for determining the reliability of data transmission. Other CSI reports refer to other beam reports other than event-associated CSI reports and LTM CSI reports. Therefore, by setting the priority of the event-associated CSI report, the communication quality is ensured.

[0115] The embodiment of the present application can also perform other processing on the n events, and the embodiment of the present application is not specifically limited.

[0116] S230, a first beam report is acquired, and the first beam report is sent to the network device 102.

[0117] The first beam report is a combined report, and the beam report corresponding to the m events is included. In addition, the priority value of the reported beam report of the event is also included.

[0118] In an example, the terminal device 101 can arrange the beam reports of the m events in the order from high to low according to the beam report priority values of the m event types based on the beam report priority values of the m event types, obtain a first beam report, and send the first beam report to the network device 102. For example, the m events include a first event, a second event, and a third event, the CSI report priority value of the first event is less than the CSI report priority value of the second event, and the CSI report priority value of the second event is less than the CSI report priority value of the third event. The first beam report obtained is shown in Table 4. The beam report content corresponding to each event is encoded according to the encoding specification of Table 2. Thus, the network device 102 can accept the beam report of the event that is preferentially reported based on the first beam report described in Table 4.

[0119] Table 4

[0120] Example explanation: If the terminal device 101 reports the beam reports of the first event, the second event, and the third event on the first available transmission occasion. The terminal device 101 first acquires the CSI report priority value "priority n" of the beam report of the first event, the CSI report priority value "priority n+1" of the beam report of the second event, and the CSI report priority value "priority n+2" of the beam report of the third event. The terminal device 101 adds priority identification information such as the corresponding event type and / or the CSI report priority value in the first beam report. Thus, the terminal device 101 can distinguish different event types based on the CSI report priority value in the first beam report shown in Table 5.

[0121] S240, the terminal device 101 determines that the beam report is associated with one event and the event type of the one event.

[0122] If the terminal device 101 determines that the reported event on the first available transmission occasion does not satisfy the condition 1, the condition 2, and the condition 3, the terminal device 101 determines that the beam report is associated with one event, and further judges the event type of the one event.

[0123] The event type includes, but is not limited to, Event-1, Event-2, and Event-7.

[0124] S250, if the event type is Event-1, a second beam report is sent to the network device 102.

[0125] If the event type is Event-1, the terminal device 101 sends a second beam report to the network device 102.

[0126] The second beam report includes the measurement value of the RS of Event-1. The measurement value of the RS includes the L1-RSRP difference value or L1-SINR difference of the TCI state associated RS.

[0127] For example, the second beam report is shown in Table 5, which only includes the L1-RSRP difference value of the current beam. The L1-RSRP difference value of the current beam refers to the difference value of the current beam relative to the first threshold value, so that the network device 102 can calculate the L1-RSRP #1 of the best beam based on the L1-RSRP difference value of the current beam and the first threshold value.

[0128] Table 5

[0129] Further, the terminal device 101 can specify the encoding rule, specifically, the L1-RSRP difference value of the current beam occupies a preset bit number, for example, the preset bit number is 4 bits. That is, the network device 102 can determine whether the event type of the beam report is Event-1 according to the fact that the beam report only contains the measurement value of one RS, and the measurement value is a difference value with a bit width of 4 bits.

[0130] In addition, the second beam report can also include the beam index of the RS, for example, the RS is candidate beam 1, and the corresponding beam index is CRI or SSBRI #1.

[0131] Further, the beam report can also include the step of the L1-RSRP difference value of Event-1. The terminal device 101 can reduce the step value, for example, from the existing step value of 2 dB to 1 dB or 0.5 dB, etc., thereby increasing the bit width, such as to 5 bits, and further increasing the accuracy of the L1-RSRP value. The step value can also be increased, for example, from the existing step value of 2 dB to 4 dB, etc., to reduce the bit width, such as to 3 bits, thereby reducing the accuracy of the L1-RSRP.

[0132] The step of the L1-RSRP differential value refers to the difference between two adjacent reportable L1-RSRP differential values. The smaller the step, the higher the accuracy of the L1-RSRP differential value. The increase in the accuracy of the L1-RSRP differential value leads to an increase in the required bitwidth.

[0133] Thus, by designing a dedicated beam report format for Event-1, the network device 102 can identify Event-1 based on the dedicated beam report format and / or the differential value with a bitwidth of 4 bits.

[0134] S260, if the event type is Event-2 or Event-7, a third beam report is sent to the network device 102.

[0135] The third beam report includes first identification information indicating Event-2 or Event-7.

[0136] Specifically, to avoid the influence of the first identification information on other beam information, the third beam report adds a padding field of the first identification information relative to the current beam report, which is used to fill the first identification information. Further, the coding specification of the padding field can be limited, for example, the occupied bitwidth is 1 bit. For example, as shown in Table 6, a format of the third beam report provided by an embodiment of the present application adds the first identification information at the end of the beam report.

[0137] Table 6

[0138] Thus, after the network device 102 receives the third beam report, the event type can be determined based on the first identification information.

[0139] S270, the network device 102 parses the beam report to determine the event type corresponding to the beam event.

[0140] After the network device 102 receives the beam report, the network device can parse the beam report. If the beam report received by the network device 102 is a beam report, the network device can parse the beam report to obtain the priority value of the beam report. Based on the priority value of the beam report, the event type corresponding to the beam report can be determined. In an example, if the event type associated with the reportConfigID is 1, the network device 102 can determine the unique reportConfigID corresponding to the event based on the CSI report priority value associated with the event, and then determine the event type associated with the reportConfigID.

[0141] For example, the network device 102 parses the beam report, obtains the CSI report priority value associated with the event, and uniquely determines the reportConfigID based on the correspondence between the CSI report priority value associated with the event and the reportConfigID, and then determines the event type associated with the reportConfigID.

[0142] In another example, if the event type associated with the reportConfigID is greater than 1, the network device 102 can parse the beam report, obtain the CSI report priority value associated with the event, and then determine the reportConfigID. The network device 102 determines the multiple event types associated with the reportConfigID. Then, the network device 102 can determine the specific event type corresponding to the beam report based on the first identification information and / or the format of the beam report. In addition, the network device 102 can also determine the specific event type based on a pre-defined configuration strategy or other ways. Alternatively, the network device 102 can determine the event type associated with the CSI report based on the resource configuration information parsed from the beam report.

[0143] In addition, the network device can determine whether the event type of the beam report is Event-1 based on the measurement value of only one RS in the beam report. Alternatively, the network device can determine whether the event type of the beam report is Event-1 based on the measurement value of only one RS in the beam report and the measurement value being a differential value with a bit width of 4 bits. For example, if the beam report only contains a differential value of L1-RSRP with a bit width of 4 bits or a differential value of L1-SINR with a bit width of 4 bits, it is determined that the event type of the corresponding beam report is Event-1.

[0144] In this way, after receiving the differential value of L1-RSRP with a bit width of 4 bits or the differential value of L1-SINR with a bit width of 4 bits, the network device 102 can calculate the absolute value of L1-RSRP or the absolute value of L1-SINR according to the known threshold value, which saves 3 bits of overhead and achieves the same effect compared to directly receiving 7 bits of L1-RSRP value or L1-SINR value.

[0145] If the beam report is a third beam report, the first identification information indicating Event-2 or Event-7 is obtained by parsing the third beam report. In this way, the network device 102 can determine the event type of the beam report based on the first identification information.

[0146] Thus, in the case that the terminal device reports the beam report associated with multiple events at the first available transmission occasion, the CSI report priority value related to the event type priority of the event is used to determine the first beam report, the first beam report is sent, and in the case that the beam report is associated with one event at the first available transmission occasion and the event type is the first event type, the event type corresponding to the beam report is sent to the network device by including the measurement value of the RS of Event-1 in the second beam report. Thus, the network device can determine the event type corresponding to the received beam report, and the terminal device can improve the effect of the network device adjusting the beam direction and obtain the beam configuration with the best call quality in the case of uplink control information conflict or limited uplink transmission resources, thereby improving the communication quality.

[0147] In addition, in the case that one beam is associated with multiple event types, the beam reports of multiple events can be reported in a combined manner. That is, the first beam report includes the combined beam reports of multiple events. Thus, the signaling overhead can be reduced and the transmission quality can be improved by using the beam report.

[0148] In the embodiment of the present application, the terminal device 101 defines a combination rule.

[0149] In an example, the combination rule can be that the terminal device 101 reports the L1-RSRP of the beam and the target candidate beam of the target priority event in multiple events. The target priority event can be the highest priority event or a specified priority event in multiple events, and the embodiment of the present application does not make a specific limitation. Thus, the event with higher user demand can be reported in priority, and therefore the network device 102 can obtain the key information in time.

[0150] For example, the target priority event is the highest priority event in multiple events. Relative to Event-7 and Event-1, Event-2 is the highest priority event, and the target priority event is Event-2. The N candidate beams of Event-2 and the L1-RSRP#1 of the RS are reported.

[0151] Example: The first beam report is shown in Table 7. Wherein #1-#N1 is the beam of Event-2, #N1-#N is the beam of other events. And the reported L1-RSRP#1 for Event-2 is the measurement value L1-RSRP#1 of Event-2, the beam information further includes the L1-RSRP differential value of the current beam of Event-2, the L1-RSRP differential value of the current beam of Event-7, and the L1-RSRP differential value of the current beam of Event-1.

[0152] Table 7

[0153] In another example, the merging specification can be: the multiple events reported by the terminal include Event-1, and the L1-RSRP differential value of the current beam of Event-1 is reported. For Event-1, only the L1-RSRP differential value of the current beam of Event-1 is reported, which can reduce the reporting content and reduce the transmission data amount.

[0154] In yet another example, the merging specification is: if the L1-RSRP differential value of the current beam must be reported, and there are multiple events whose current beams are the same RS and the same measurement result, they can be merged into one L1-RSRP differential value of the current beam for reporting. By merging the L1-RSRP differential values of the current beams of multiple events, the transmission of repeated data can be reduced, and the transmission efficiency can be improved.

[0155] The merging method is introduced as follows:

[0156] If the current beams of Event-2+Event-1 / Event-2+Event-7 / Event-7+Event-1 are merged, only one L1-RSRP differential value is reported.

[0157] If the current beams of Event-2+Event-7+Event-1 are all merged, only one L1-RSRP differential value is reported.

[0158] If the current beams of Event-2+Event-7+Event-1 are partially merged, the L1-RSRP differential values of the merged current beams and the L1-RSRP differential values of the current beams of the events that are not merged are reported, etc.

[0159] Further, in order to enable the network device 102 to fully understand which events are merged, an event type indication is added to indicate the merging of the event type.

[0160] For example, if the current beams of Event-2+Event-1 / Event-2+Event-7 / Event-7+Event-1 are merged, only one L1-RSRP differential value is reported, and the two events used for merging are determined according to the event identifier. If the current beams of Event-2+Event-7+Event-1 are partially merged, 2 bits of additional indication are also needed to indicate which two events are merged, or in this case, no merging. By using additional indication bits to indicate which events are merged, the network device 102 can more easily understand and process.

[0161] In yet another example, the merging rule includes that the terminal device 101 reports the L1-RSRP of the beam and RS of the target priority event in multiple events, and the multiple events reported by the terminal include Event-1, and the terminal reports the differential value of the L1-RSRP of the current beam of Event-1, and in addition, if the differential value of the L1-RSRP of the current beam must be reported, and there are multiple events whose current beam is the same RS and the same measurement result, they can be merged into one differential value of the L1-RSRP of the current beam for reporting. Thus, the information of the first beam report can be made more comprehensive, and the network device 102 can thus accurately obtain the event type and the beam information of each event.

[0162] In addition, the terminal device 101 can also add an event type indication in the first beam report, which is used to indicate the event type. Further, the encoding rule for indicating the event type can be limited, for example, bitwidth is 2 bits, indicating 4 combinations, if 1 bit is to indicate 2 single events, and if bitwidth is 3 bits, it is used to indicate all 7 event types.

[0163] Further, the terminal device 101 can also add second identification information for each beam in the beam report, which is used to indicate whether the beam satisfies the event condition.

[0164] In an example, the second identification information is the sign of the L1-RSRP differential value. For example, if the value of the L1-RSRP differential value is positive, it is determined that the event condition is satisfied, and if the value of the L1-RSRP differential value is negative, it is determined that the event condition is not satisfied. Thus, the network device 102 can determine whether the current beam satisfies the event condition based on the second beam information, and further determine the event type of the current event. For example, the value of L1-RSRP differential value #2 is positive, and the values of L1-RSRP differential value #3 to L1-RSRP #N are negative, it is determined that the candidate beam 2 satisfies the event condition.

[0165] Further, to improve the identification accuracy, the range of the L1-RSRP differential value is updated, for example, the previous range of the L1-RSRP differential value is 0-30 dB, which is updated to -15-15 dB or -30-30 dB. Thus, by making the updated range of the L1-RSRP differential value about the origin, the identification accuracy is improved.

[0166] In addition, the step of the L1-RSRP differential value can also be updated as needed, for example, the step of 2 dB is updated to 4 dB, etc.

[0167] Further, if the beam report is only associated with one event, a first preset bit width is added to indicate whether the event is satisfied. The first preset bit width is a bit width set by a person skilled in the art as needed, for example, the preset bit width is or wherein, N i is the N value configured by Event-i, i = 2 or i = 7.

[0168] Further, if the beam report is associated with n events, a second preset bit width indication is added after the last L1-RSRP differential value of each event. The second preset bit width indication is used to indicate the event type. The second preset bit width is a bit width set by a person skilled in the art according to needs. For example, the second preset bit width is N MAX is the maximum value of Event-j, 7 > j > 1.

[0169] Further, Event-1 does not need to be indicated.

[0170] It should be noted that whether the added indication information meets the event needs the L1-RSRP differential value to be arranged in ascending order or descending order.

[0171] Therefore, by adding the bit width indication, the network device 102 can clearly know which beams meet the requirements of the event, and understand the event type associated with the beam report.

[0172] In summary, by adding the indication information or the second identification information in the beam report, the network device 102 can better understand which beams meet the requirements and which beams do not meet the requirements of the event, thereby improving the communication quality between the network device 102 and the terminal device 101.

[0173] Further, the embodiment of the present application provides a specific implementation of reporting a beam report. The following will be described in detail in combination with FIG. 3-FIG. 4.

[0174] FIG. 3 is a communication method interaction diagram provided by the embodiment of the present application, the method is shown in the communication system of FIG. 1, and the method comprises the following steps:

[0175] S310, the terminal device 101 sends a first PUCCH request resource to the network device 102.

[0176] The first PUCCH request resource is used to request the terminal device to bear the beam report resource of the second uplink channel. The second uplink channel is different from the first PUCCH. The second uplink channel can be PUCCH or PUSCH, and the embodiment of the present application does not specifically limit it.

[0177] In an example, if the bit width of the beam report is less than a first bit width threshold, the beam report can be directly transmitted through the PUCCH. If the beam report is greater than the first bit width threshold, the beam report needs to be transmitted through the PUSCH. In some cases, part of the control information can be transmitted through the PUCCH, and detailed data can be transmitted through the PUSCH. The first bit width threshold is an optimal threshold set by the art as needed.

[0178] The first PUCCH request resource format can be a scheduling request (SR) type or an uplink control information (UCI) type, and the embodiments of the present application are not specifically limited.

[0179] In an example, if the terminal device 101 needs to transmit a beam report on the second uplink channel, but the link resources do not meet the resource needs of the beam report, the terminal device 101 can transmit an SR type first PUCCH request resource through the first PUCCH. If the terminal device 101 needs to request to carry control information, the terminal device 101 can use a UCI type first PUCCH request resource.

[0180] S320, the network device 102 sends an indication of a resource carrying a beam report to the terminal device 101.

[0181] The indication of the resource carrying the beam report is used to instruct the terminal device to carry the beam report through the resource of the second uplink channel.

[0182] S330, the terminal device 101 transmits a beam report to the network device 102 through the second uplink channel.

[0183] The beam report is one of the first beam report, the second beam report, or the third beam report obtained in the manner described in FIG. 2.

[0184] S340, the network device 102 parses the beam report and obtains beam information.

[0185] In the embodiments of the present application, by transmitting a PUCCH request, resource management can be optimized, and it can be ensured that the beam report can be transmitted in a timely and accurate manner. Requesting resources on the PUCCH can reduce the risk of conflict when the beam report is transmitted on the PUSCH, because the resources have been allocated in advance. Then, through the explicit beam report indication information, it can be ensured that the terminal device 101 transmits the beam report on the correct resource, and the transmission efficiency is improved.

Wherein, the format of the first PUCCH notifying the preconfigured resource can be an SR type or a UCI type, and the embodiments of the present application do not specifically limit.

[0188] Wherein, the UCI is located in the preconfigured resource of the second uplink channel.

[0189] S420, the terminal device 101 sends a beam report through the preconfigured resource of the second uplink information.
