Furthermore, multiple systems may be combined (for example, a combination of LTE or LTE-A with 5G).

[0278] Optionally, in a communication system, when a terminal reports a beam report to a network device, the network device typically first configures the reporting timing for the beam report for the terminal, and the terminal then reports the beam report based on the reporting timing configured by the network device. Optionally, the network device typically configures the terminal to report beam reports periodically, semi-persistently, or aperiodically. However, in reality, changes in beam quality are most readily known to the terminal, and the reporting timing configured by the network device (such as the periodic reporting period or the aperiodic reporting period) may not be optimal. For example, if the reporting interval is too short, the optimal beam reported twice may be the same, without change, thus wasting signaling. If the reporting interval is too long, a situation may occur where "beam quality changes but the reporting timing has not yet arrived," thereby affecting communication quality. Currently, event-triggered beam reporting has been proposed to address this issue. Specifically, the terminal determines whether a triggering event is met based on its own beam quality. When the triggering event is met, the terminal triggers the reporting of the beam report, thereby achieving timely and accurate reporting of beam reports. However, the above triggering events may be satisfied within a period of time. During this period of time, the terminal will continue to report, which will cause additional signaling overhead and waste of resources.

[0279] FIG2A is an interactive diagram of a beam reporting method according to an embodiment of the present disclosure. As shown in FIG2A , the embodiment of the present disclosure relates to a beam reporting method for a communication system 100, the method comprising:

[0280] Step 2101: The network device configures at least one trigger event.

[0281] Optionally, the network device may configure the at least one trigger event for the terminal, and the terminal may receive the at least one trigger event configured by the network device.

[0282] In some embodiments, the trigger event can be used to trigger the terminal to send a beam report. Optionally, the trigger event can correspond to a trigger condition, and the "trigger event is used to trigger the terminal to send a beam report" here can be understood as: when the terminal meets the trigger condition corresponding to the trigger event, the terminal can send a beam report.

[0283] Optionally, the above mentioned concepts of "triggering the terminal to send a beam report" and "terminal sending a beam report" are different. Specifically, "triggering the terminal to send a beam report" means: the terminal determines that it is going to send a beam report, but the beam report has not been generated at this time, or the beam report has been generated but has not been sent, that is, the terminal only knows that it is going to send a beam report, but has not yet performed the action of "sending a beam report", but is about to perform the action of "sending a beam report". To execute the sending of a beam report, a specific triggering condition for sending a beam report needs to be met, that is, when the specific triggering condition for sending a beam report is met, the beam report can be sent, that is, "the terminal sending a beam report" means: the terminal is performing the action of "sending a beam report".

[0284] Optionally, the triggering condition corresponding to the triggering event may include an entering condition corresponding to the triggering event and / or a leaving condition corresponding to the triggering event. The triggering event and the triggering condition corresponding to the triggering event are introduced below with examples.

[0285] Optionally, in some embodiments, the at least one triggering event may include one or more of the following:

[0286] The first event is: the beam quality of the current beam is lower than the first threshold;

[0287] The second event is: the beam quality of the candidate beam is higher than a second threshold value;

[0288] The third event is: the beam quality of the candidate beam is higher than the beam quality of the current beam by a preset offset value.

[0289] Optionally, in some embodiments, the entry condition corresponding to the first event may include: a sum of a beam quality of a current beam and the first value is less than a third threshold value;

[0290] Optionally, in some embodiments, the exit condition corresponding to the first event may include: a difference between the beam quality of the current beam and the second value is greater than a fourth threshold value.

[0291] Optionally, in some embodiments, the entry condition corresponding to the second event may include: a difference between the beam quality of the candidate beam and the third value is greater than a fifth threshold value;

[0292] Optionally, in some embodiments, the exit condition corresponding to the second event may include: the sum of the beam quality of the candidate beam and the fourth value is less than a sixth threshold value.

[0293] Optionally, in some embodiments, the entry condition corresponding to the third event may include: a difference between the beam quality of the candidate beam and the fifth value is greater than a sum of the beam quality of the current beam and the first offset value;

[0294] Optionally, in some embodiments, the exit condition corresponding to the third event may include: the sum of the beam quality of the candidate beam and the sixth value is less than the sum of the beam quality of the current beam and the second offset value.

[0295] Optionally, the first value, second value, third value, fourth value, fifth value, sixth value, first threshold value, second threshold value, third threshold value, fourth threshold value, fifth threshold value, sixth threshold value, first offset value, second offset value, and preset offset value may be configured by the network device, or may be agreed upon by a protocol. Furthermore, the first value, second value, third value, fourth value, fifth value, and sixth value may be the same or different, the first threshold value, second threshold value, third threshold value, fourth threshold value, fifth threshold value, and sixth threshold value may be the same or different, and the first offset value, second offset value, and preset offset value may be the same or different.

[0296] Optionally, the meaning of the entry condition corresponding to the triggering event can be understood as, for example, the conditions under which the terminal is considered to have entered the scene corresponding to the triggering event, that is, when the terminal meets the entry condition of a certain triggering event, it is said that the terminal has entered the scene corresponding to the triggering event. Optionally, the meaning of the exit condition corresponding to the triggering event can be understood as, for example, the conditions under which the terminal is considered to have left the scene corresponding to the triggering event, that is, when the terminal meets the exit condition of a certain triggering event, it is said that the terminal has left the scene corresponding to the triggering event.

[0297] For example, the meaning of the above-mentioned entry conditions and exit conditions is introduced by taking the first event as an example. Optionally, the scenario corresponding to the above-mentioned first event "the beam quality of the current beam is lower than the first threshold value" may be: the beam quality of the current beam of the terminal is low. On this basis, when the terminal meets the entry condition corresponding to the first event, that is, when the sum of the beam quality of the current beam of the terminal and the first value is less than the third threshold value, it means that the terminal has entered the scenario corresponding to the first event, that is, the beam quality of the current beam of the terminal is low; and when the terminal meets the exit condition corresponding to the first event, that is, when the difference between the beam quality of the current beam of the terminal and the second value is greater than the fourth threshold value, it means that the terminal has left the scenario corresponding to the first event, that is, the beam quality of the current beam of the terminal is not low, or the beam quality of the current beam is acceptable.

[0298] That is to say, the network device may need a beam report from the terminal in specific situations, for example, to determine whether the quality of the current beam is good, or whether the candidate beam is better than the quality of the current beam, so as to perform beam switching, cell reselection and other behaviors. Take the first event that the beam quality of the current beam is lower than the first threshold value as an example. The network device needs to obtain the beam quality of the current beam, and uses the beam quality of the current beam lower than the first threshold value as a trigger event. When the trigger condition is the entry condition, the terminal evaluates the beam quality of the current beam. If the sum of the current beam quality and the first value is less than the third threshold value (the third threshold value can be the same as or different from the first threshold value), it means that the current beam quality is less than a certain value. It can be considered that the current beam quality is poor, and the beam report is sent to the network device to inform the network device of the current beam quality. The network device can determine that the beam quality of the current beam is poor based on the beam report. Similarly, when the trigger condition is the leaving condition, the terminal evaluates the beam quality of the current beam. If the difference between the current beam quality and the second value is greater than the fourth threshold value (the fourth threshold value may be the same as or different from the first threshold value), it means that the current beam quality is greater than a certain value. It can be considered that the current beam quality is not bad, or the current beam quality is acceptable, so the beam report is sent to the network device to inform the network device of the current beam quality. The network device can determine that the beam quality of the current beam is acceptable based on the beam report, or that the current beam quality is no longer bad. The network device does not need to perform the operations expected to be performed when the current beam quality is poor.

[0334] Step 2102: The network device configures a reporting threshold and / or a reporting interval.

[0335] Optionally, the network device may configure a reporting number threshold value and / or a reporting interval value for the terminal, and the terminal may receive the reporting number threshold value and / or the reporting interval value configured by the network device.

[0336] Optionally, in some embodiments, the aforementioned reporting threshold may be used to indicate the maximum number of beam reports that may be reported while the trigger condition corresponding to the trigger event is satisfied. Optionally, the total number of beam reports that may be reported while the trigger condition corresponding to the trigger event is satisfied must be less than or equal to the reporting threshold.

[0337] Optionally, in some embodiments, the aforementioned reporting interval value may be used to indicate: during the period when the trigger condition corresponding to the trigger event is satisfied, the interval value required to be satisfied between two adjacent beam reports. Optionally, during the period when the trigger condition corresponding to the trigger event is satisfied, the time interval between two adjacent beam reports must be greater than or equal to the reporting interval value.

[0338] Optionally, in some embodiments, the entry condition and exit condition of the same trigger event each correspond to a reporting number threshold value and / or a reporting interval value; wherein the entry condition and exit condition of the same trigger event satisfy at least one of the following:

[0339] The reporting thresholds corresponding to the entry and exit conditions of the same trigger event are the same or different

[0340] The reporting interval values ​​corresponding to the entry condition and the exit condition of the same trigger event are the same or different.

[0341] For example, in some embodiments, the reporting number threshold values ​​corresponding to the entry condition and exit condition of the same trigger event can be, for example, 3 times and 1 time respectively, and the reporting interval values ​​corresponding to the entry condition and exit condition of the same trigger event can be, for example, 5 milliseconds (ms) and 6 milliseconds (ms) respectively.

[0342] Optionally, when the reporting number threshold values ​​corresponding to the entry conditions and exit conditions of the same triggering event are the same, the reporting number threshold values ​​corresponding to the entry conditions and exit conditions of the same triggering event can be determined based on the same parameter value in the same indication information, or, the reporting number threshold values ​​corresponding to the entry conditions and exit conditions of the same triggering event can be determined based on the same parameter value agreed upon in the protocol; when the reporting number threshold values ​​corresponding to the entry conditions and exit conditions of the same triggering event are different, the reporting number threshold values ​​corresponding to the entry conditions and exit conditions of the same triggering event can be determined based on different parameter values ​​in the same indication information; or, the reporting number threshold values ​​corresponding to the entry conditions and exit conditions of the same triggering event can be determined based on different parameter values ​​agreed upon in the protocol.

[0343] Optionally, when the reporting interval values ​​corresponding to the entry conditions and exit conditions of the same trigger event are the same, the reporting interval values ​​corresponding to the entry conditions and exit conditions of the same trigger event can be determined based on the same parameter value in the same indication information, or the reporting interval values ​​corresponding to the entry conditions and exit conditions of the same trigger event can be determined based on the same parameter value agreed upon in the protocol; when the reporting interval values ​​corresponding to the entry conditions and exit conditions of the same trigger event are different, the reporting interval values ​​corresponding to the entry conditions and exit conditions of the same trigger event can be determined based on different parameter values ​​in the same indication information, or; the reporting interval values ​​corresponding to the entry conditions and exit conditions of the same trigger event can be determined based on different parameter values ​​agreed upon in the protocol.

[0344] Optionally, in some embodiments, the entry conditions and exit conditions of different triggering events correspond to reporting number thresholds and / or reporting intervals, respectively; wherein the entry conditions and exit conditions of different triggering events satisfy at least one of the following:

[0345] The reporting number thresholds corresponding to the entry conditions of different trigger events are the same or different;

[0346] The reporting interval values ​​corresponding to the entry conditions of different trigger events are the same or different;

[0347] The reporting number thresholds corresponding to the leaving conditions of different triggering events are the same or different;

[0348] The reporting interval values ​​corresponding to the departure conditions of different triggering events are the same or different.

[0349] Optionally, in some embodiments, when the reporting number threshold values ​​corresponding to the entry conditions of different triggering events are the same, the reporting number threshold values ​​corresponding to the entry conditions of different triggering events can be determined based on the same parameter value in the same indication information, or the reporting number threshold values ​​corresponding to the entry conditions of different triggering events can be determined based on the same parameter value agreed upon in the protocol; when the reporting number threshold values ​​corresponding to the entry conditions of different triggering events are different, the reporting number threshold values ​​corresponding to the entry conditions of different triggering events can be determined based on different parameter values ​​in the same indication information or different indication information, or the reporting number threshold values ​​corresponding to the entry conditions of different triggering events can be determined based on different parameter values ​​agreed upon in the protocol.

[0350] Optionally, when the reporting interval values ​​corresponding to the entry conditions of different trigger events are the same, the reporting interval values ​​corresponding to the entry conditions of different trigger events can be determined based on the same parameter value in the same indication information, or, the reporting interval values ​​corresponding to the entry conditions of different trigger events can be determined based on the same parameter value agreed upon in the protocol; when the reporting interval values ​​corresponding to the entry conditions of different trigger events are different, the reporting interval values ​​corresponding to the entry conditions of different trigger events can be determined based on different parameter values ​​in the same indication information or different indication information; or, the reporting interval values ​​corresponding to the entry conditions of different trigger events can be determined based on different parameter values ​​agreed upon in the protocol.

[0351] The exit conditions for different trigger events are similar and will not be elaborated here.

[0352] In addition, in some embodiments, the at least one triggering event, reporting threshold, and reporting interval may be configured simultaneously by the network device to the terminal. For example, the network device may use the same signaling to configure the at least one triggering event, reporting threshold, and reporting interval. In other embodiments, the at least one triggering event, reporting threshold, and reporting interval may be configured separately by the network device to the terminal. For example, the network device may use different signaling to configure the at least one triggering event, reporting threshold, and reporting interval. This disclosure is not limited to this.

[0353] Step 2103: The terminal determines at least one triggering event.

[0354] For a detailed introduction to the triggering events, please refer to the above step description.

[0355] Optionally, in some embodiments, the terminal may determine at least one triggering event based on a protocol agreement; in other embodiments, the terminal may receive at least one triggering event configured by a network device.

[0356] Step 2104: The terminal determines a reporting times threshold value and / or a reporting interval value.

[0357] For detailed description of the reporting number threshold and / or reporting interval value, please refer to the above step description.

[0358] Optionally, in some embodiments, the terminal may determine the reporting number threshold value and / or reporting interval value based on protocol agreement; in other embodiments, the terminal may receive the reporting number threshold value and / or reporting interval value configured by the network device.

[0359] Step 2105: When the terminal meets the trigger condition corresponding to at least one trigger event, the terminal sends a beam report.

[0360] Optionally, the terminal may send a beam report based on a trigger condition corresponding to at least one trigger event. For example, the beam report may be sent based on whether the trigger condition is met or not met.

[0361] In some embodiments, when the terminal sends a beam report, the beam report may be sent based on a reporting number threshold value and / or a reporting interval value of a trigger condition corresponding to a satisfied trigger event.

[0362] Specifically, in some embodiments, when the terminal satisfies at least one entry condition or exit condition corresponding to a triggering event, the number of times beam reports are sent may be set to 0. For example, when the terminal switches from the state of "not satisfying the entry condition corresponding to the triggering event" to the state of "satisfying the entry condition corresponding to the triggering event", the number of times beam reports are sent may be set to 0; or, when the terminal switches from the state of "not satisfying the exit condition corresponding to the triggering event" to the state of "satisfying the exit condition corresponding to the triggering event", the number of times beam reports are sent may be set to 0. Furthermore, after the number of times beam reports are sent is set to 0, the number of times beam reports are sent is counted by 1 each time a beam report is sent. When the counted number of times beam reports are sent is not less than the reporting number threshold corresponding to the currently satisfied entry condition or exit condition, beam reports are stopped from being sent. Also, during the period when the entry condition or exit condition corresponding to at least one triggering event is met, when the beam report is sent for the i-th time (i is a positive integer greater than 1), a first time point can be determined. When the time interval between the first time point and the time point when the beam report was last sent is greater than or equal to the reporting interval value corresponding to the currently met entry condition or exit condition, the i-th beam report is sent at the first time point.

[0363] For example, assuming that the sum of the beam quality of the current beam of the terminal and the first value is less than the third threshold value, it is determined that the terminal meets the entry conditions of the first event. At this time, if the reporting number threshold value corresponding to the entry conditions of the first event is 5 times, and the reporting interval value corresponding to the entry conditions of the first event is 5ms, then when the terminal switches from the state of "not meeting the entry conditions corresponding to the first event" to the state of "meeting the entry conditions corresponding to the first event", the number of beam reports sent can be set to 0, and after setting the number of beam reports sent to 0, if the terminal sends the first beam report to the network device at the first moment n, the number of beam reports sent will be counted as 1, and the terminal can determine the "n+5 (ms) moment" as the second moment, and can then send a second beam report to the network device at a time point after the second moment (that is, the aforementioned first time point), and count the number of beam reports sent to 2, and so on, until the number of beam reports sent is counted to 5, then stop sending beam reports.

[0364] In addition, it should be noted that when the terminal satisfies the trigger conditions corresponding to multiple trigger events, and the reporting number threshold values ​​and / or reporting interval values ​​of the trigger conditions corresponding to the multiple trigger events are different, the terminal can send beam reports corresponding to each trigger event based on the reporting number threshold value and / or reporting interval value of the trigger conditions corresponding to each trigger event that is satisfied, or the terminal can merge and report the beam reports corresponding to each trigger event that is satisfied, and when merging and reporting, the beam reports corresponding to each trigger event can be merged and reported based on the reporting number threshold value and / or reporting interval value of the trigger conditions corresponding to any trigger event among the multiple trigger events satisfied by the terminal.

[0365] For example, assuming that the terminal satisfies both the entry condition of the first event and the entry condition of the second event, the beam report corresponding to the entry condition of the first event may include at least one of the following:

[0366] At least one first identifier, where the first identifier is used to indicate a reference signal resource corresponding to a current beam;

[0367] The beam quality of the current beam;

[0368] The terminal's SRS port support capability;

[0369] The power headroom of the terminal;

[0370] The power backoff amount corresponding to the terminal's MPE;

[0371] The terminal's uplink transmission power;

[0372] a second identifier, the second identifier being used to indicate the first event;

[0373] A third identifier is used to indicate a report configuration identifier, and the report configuration identifier is associated with the second identifier indicating the first event.

[0374] Furthermore, the beam report corresponding to the entry condition of the second event may include at least one of the following:

[0375] At least one first identifier, where the first identifier is used to indicate a reference signal resource corresponding to the candidate beam;

[0376] Beam quality of candidate beams;

[0377] The terminal's SRS port support capability;

[0378] The power headroom of the terminal;

[0379] The power backoff amount corresponding to the terminal's MPE;

[0380] The terminal's uplink transmission power;

[0381] a second identifier, the second identifier being used to indicate a second event;

[0382] A third identifier is used to indicate a report configuration identifier, and the report configuration identifier is associated with the second identifier indicating the second event.

[0383] At this time, if the reporting number threshold value and / or reporting interval value of the entry condition of the first event is different from the reporting number threshold value and / or reporting interval value of the entry condition of the second event, the terminal can report the beam report corresponding to the entry condition of the first event based on the reporting number threshold value and / or reporting interval value of the entry condition of the first event, and report the beam report corresponding to the entry condition of the second event based on the reporting number threshold value and / or reporting interval value of the entry condition of the second event. Alternatively, the terminal can merge the beam report corresponding to the entry condition of the first event and the beam report corresponding to the entry condition of the second event, and can perform the above-mentioned merged reporting based on the reporting number threshold value and / or reporting interval value of the entry condition of the first event, or based on the reporting number threshold value and / or reporting interval value of the entry condition of the second event.

[0384] Step 2106: The network device receives the beam report and sends the first information to the terminal.

[0385] Optionally, the first information can be used to inform the terminal that the network device has received the beam report.

[0386] Optionally, the first information may include at least one of the following:

[0387] Hybrid Automatic Repeat request Acknowledgement (HARQ ACK) feedback;

[0388] Hybrid Automatic Repeat request Negative Acknowledgement (HARQ NACK) feedback;

[0389] First signaling; the first signaling is used to schedule a HARQ process number of a physical uplink shared channel (PUSCH), and the HARQ process number of the PUSCH scheduled by the first signaling is the same as the HARQ process number of the previous PUSCH; optionally, the first signaling may be: DCI signaling;

[0390] Second signaling, where the second signaling may be used to activate at least one of a DL TCI state, a joint TCI state, and a UL TCI state, wherein a reference signal (RS) corresponding to the TCI state activated by the second signaling includes an RS in a most recent beam report of the terminal; optionally, the second signaling may be MAC CE signaling;

[0391] The third signaling can be used to indicate at least one of the DL TCI state, the joint TCI state, and the UL TCI state. The RS corresponding to the TCI state indicated by the third signaling includes the RS in the terminal's most recent beam report; optionally, the third signaling can be: DCI signaling.

[0392] Optionally, after receiving the beam report, the network device can perform some scheduling based on the beam report. For example, the network device can determine a beam with higher beam quality based on the beam report, and schedule the beam with higher beam quality for sending and receiving channels and / or signals, thereby ensuring communication quality; or, when the network device determines that the beam quality of the terminal's current beam is higher based on the beam report, the terminal can be scheduled to stop measuring other candidate beams, thereby avoiding the terminal from performing some unnecessary measurements and saving terminal power consumption.

[0393] Step 2107: The terminal stops sending beam reports.

[0394] Optionally, when the terminal receives the first information after sending the beam report, the terminal stops sending the beam report.

[0395] Optionally, in some embodiments, the above steps 2107 and 2105 may be performed either one or in combination.

[0396] In some embodiments, the above-mentioned step 2105 may be performed, that is, whether to stop sending the beam report is determined based on the reporting number threshold value and / or reporting interval value in step 2105. For example: when the terminal determines that the trigger condition corresponding to at least one trigger event is met and sends a beam report, the terminal may determine the reporting number and reporting frequency of the beam report based on the reporting number threshold value and / or reporting interval value. The sending of the beam report is stopped only when the number of beam reports sent reaches the reporting number threshold value. During this period, even if the first information is received, if the number of beam reports sent does not reach the reporting number threshold value, the beam report is still sent until the number of beam reports sent reaches the reporting number threshold value.

[0397] In some other embodiments, the above-mentioned step 2107 may be performed, that is, whether to stop sending the beam report is determined based on whether the first information is received. For example: when the terminal determines that the trigger condition corresponding to at least one trigger event is satisfied and sends the beam report, the number of reports and the reporting frequency of the beam report may be determined based on the reporting number threshold value and / or the reporting interval value, or the terminal may report the beam report in real time when determining that the trigger condition corresponding to at least one trigger event is satisfied; and, once the terminal receives the first information, even if the number of reports of the beam report has not reached the reporting number threshold value, or even if the reporting interval value is satisfied between the current time point and the time point when the beam report was last sent, the beam report will be stopped from being sent.

[0398] In some other embodiments, the above steps 2105 and 2107 may be performed, that is, whether to stop sending the beam report is determined based on whether the first information is received and the reporting number threshold value and / or reporting interval value. For example, when the terminal determines that the trigger condition corresponding to at least one trigger event is met and sends the beam report, the terminal may determine the reporting number and reporting frequency of the beam report based on the reporting number threshold value and / or reporting interval value, and only when the number of times the beam report is sent reaches the reporting number threshold value and the terminal receives the first information, the terminal stops sending the beam report.

[0399] It can be seen from this that the terminal will determine the reporting number threshold value and / or reporting interval value, and when the terminal meets the entry condition or exit condition corresponding to at least one triggering event, the terminal will limit the terminal's reporting number and reporting frequency for beam reports based on the reporting number threshold value and / or reporting interval value, thereby avoiding the terminal from frequently and unnecessarily sending beam reports, reducing signaling overhead, and avoiding waste of resources. At the same time, in some embodiments, after the terminal sends a beam report, if the network device receives the beam report, it will send a first message to the terminal to inform the terminal that the network device has received the beam report. At this time, the terminal will stop sending beam reports to reduce unnecessary signaling overhead and save unnecessary resource waste.

[0400] In the above embodiment, the terminal will determine the triggering event for triggering the beam report, and when the triggering conditions of at least one triggering event are met, the terminal will send the beam report. It can be seen that in the beam reporting method provided by the present disclosure, the terminal determines the reporting time of the beam report based on whether the triggering conditions corresponding to the triggering event are met. By flexibly setting the specific triggering conditions of the triggering event, the terminal can report the beam report in a timely and accurate manner at the appropriate time, avoiding the situation where "the beam reporting interval configured by the network device is too short, which may make the best beams reported twice the same and unchanged, thereby wasting signaling, and the beam reporting interval configured by the network device is too long, which may cause the beam quality to change. The beam report is not sent because the reporting time has not arrived, thereby affecting the communication quality." This can reduce signaling overhead and ensure that when the beam quality changes, it can be reported in time to ensure communication quality.

[0401] The beam reporting method involved in the embodiments of the present disclosure may include at least one of steps 2101 to 2107. For example, step 2101 may be implemented as an independent embodiment, step 2102 may be implemented as an independent embodiment, step 2103 may be implemented as an independent embodiment, and step 2101+S2102 may be implemented as an independent embodiment, but the present invention is not limited thereto.

[0402] In this embodiment or example, unless there is any contradiction, each step can be independent, arbitrarily combined or exchanged in order, the optional methods or optional examples can be arbitrarily combined, and can be arbitrarily combined with any steps of other embodiments or other examples.

[0531] In this embodiment or example, unless there is any contradiction, each step can be independent, arbitrarily combined or exchanged in order, the optional methods or optional examples can be arbitrarily combined, and can be arbitrarily combined with any steps of other embodiments or other examples.

[0532] The following is an exemplary introduction to the above method.

[0533] Optional Example 1: The terminal determines a triggering event, where the triggering event is used to trigger a beam report. If the terminal determines that a triggering condition corresponding to the triggering event is satisfied, the beam report is triggered.

[0534] a) The beam can be called beam, spatial Rx parameter, QCL (quasi-co location) Type D, spatial setting, spatial reception filter, spatial transmission filter, spatial domain filter, TCI state, joint TCI state, DL TCI state, UL TCI state, unified TCI state, common TCI state, spatialrelationinfo, etc.

[0535] Optional Example 2: The beam report includes at least one of the following:

[0536] i.SSB resource ID, CSI-RS resource ID;

[0537] ii.L1-RSRP, L1-SINR;

[0539] iv.Power headroom;

[0540] v.MPE:Power backoff;

[0541] vi.UL transmission power: for example, power headroom–power backoff;

[0542] vii.Event ID;

[0543] Optional Example 3. Based on Optional Example 1, the trigger condition includes an entering condition or a leaving condition corresponding to the trigger event. For example, the entering condition and leaving condition for the following events are as follows:

[0544] a) Event 1: The current beam quality is lower than the threshold;

[0545] 1. The entering condition is the quality of the current beam plus a value of 1 less than a threshold value of 1;

[0546] 2. The Leaving condition is that the quality of the current beam minus a value of 1 is greater than a threshold value of 1;

[0547] b) Event 2: The quality of the candidate beam is higher than the threshold;

[0548] 1. The entering condition is that the quality of the candidate beam minus a value of 2 is greater than a threshold value of 2;

[0549] 2. The Leaving condition is the quality of the candidate beam plus a value of 2 less than a threshold value of 2;

[0550] c) Event 3: The candidate beam quality is one offset higher than the current beam quality;

[0551] i. The entering condition is that the candidate beam quality minus a value of 3 is greater than the current beam quality plus an offset of 1;

[0552] ii. The Leaving condition is that the candidate beam quality plus a value of 3 is less than the current beam quality plus an offset of 1;

[0553] d) Event 4: Event 1 and Event 2 are satisfied at the same time.

[0554] Optional Example 4. Based on Optional Example 3, when the entering condition or leaving condition of the triggering event is met, the number of beam report transmissions is set to 0. If a beam report is sent once, the number of beam report transmissions is increased by 1. If the number of beam report transmissions is less than the reporting number threshold, the terminal can send a beam report. Otherwise, no beam report needs to be sent again.

[0555] a) When the number of beam reports sent is less than the reporting number threshold, it is also necessary to determine whether the time interval between two beam reports meets the interval value. Only when the time interval is greater than or equal to the interval value can the beam report be sent again.

[0556] b) The reporting number threshold and the interval value are based on the base station configuration or the protocol preset.

[0557] Optional Example 5. Based on Optional Example 4, the reporting threshold or interval value corresponding to the entering condition or the leaving condition can be set independently. For example, the reporting threshold value for the leaving condition can be set to 1.

[0558] Optional Example 6. Based on any one of Optional Examples 1-5, the terminal sends a beam report. If it receives indication information from the base station, where the indication information is used to inform the terminal that the beam report has been received, the terminal stops sending the beam report.

[0559] a) The indication information includes HARQ ACK / NACK feedback;

[0560] b) The indication information includes DCI, for example, the HARQ process number of the PUSCH scheduled by DCI is the same as the previous one;

[0562] i. The RS corresponding to the activated TCI state includes the RS in the terminal's most recent beam report;
