For example, when it is detected that the BLER of TRP 0 is greater than BLER 0 at a certain moment, it is considered that a physical layer beam failure event has occurred, and the first counter of TRP 0 is started and incremented by 1, and every subsequent detection that the BLER of TRP 0 is greater than BLER 0 , Then the first counter of TRP 0 is incremented by 1.
- the first counter of TRP 1 is started and incremented by 1.
- Each subsequent detection that the BLER of TRP 1 is greater than BLER 1 Then increment the first counter of TRP 1 by 1.
- the first counters of TRP 0 and TRP 1 count independently, and when the count of the corresponding first counter exceeds the first maximum count threshold, it is considered that the corresponding TRP has a beam failure event.

- the first maximum count threshold of the first counter of each TRP may also be the same or different. These can be configured by the base station.
- one reference signal can be configured for one TRP (as described in the above example).

Specifically, the first counter is still set for each TRP.
- the TRP When the BLER values of the beams corresponding to all reference signals of a TRP are greater than the corresponding BLER threshold, it is considered that the TRP has a physical layer beam failure event, and the TRP is the first The counter is incremented by one. If the BLER value of the beam corresponding to only a part of the reference signal exceeds the corresponding BLER threshold, the first counter of the TRP does not accumulate 1.

- the determination unit 103 determines that multiple TRPs have a joint physical layer beam failure, that is, an instance of a joint beam failure event is generated.
- the UE reports the instance of the joint beam failure event to its upper layer.
- the determining unit 103 determines that the corresponding TRP has a joint beam failure event.
- the reporting unit 102 reports to the base station to trigger the BFR process.
- the beam failure event is determined based on the joint BLER of multiple TRPs. Since in a multi-TRP scenario, the performance of the UE is determined based on the joint transmission performance of multiple TRPs, the beam failure determination based on the joint BLER can accurately reflect the degradation of the UE's performance and improve reliability.
- the determining unit 103 may perform a weighted summation of the BLER of each TRP in the plurality of TRPs according to the weighting parameter, and use the result as the joint BLER.
- the weighting parameter is set for each TRP and can be a constant in the range of 0 to 1.
- the sum of all weighting parameters is 1.
- the joint BLER is obtained by the weighted summation of the BLERs of two TRPs, and the weighting parameter is obtained by the second configuration.
- the joint BLER can be calculated by the following formula (1).
- BLER 0 is the BLER of TRP 0
- BLER 1 is the BLER of TRP 1
- w 0 and w 1 are weighting parameters corresponding to TRP 0 and TRP 1 , respectively
- BLER joint is the calculated joint BLER.
- this embodiment can also be applied to a situation where a TRP is configured with multiple reference signals.

Perform weighted summation of the BLER, and when the finally obtained BLER exceeds the joint BLER threshold, it is considered that a joint physical layer beam failure event has occurred, that is, an instance of a joint beam failure event has occurred.
- the same weighting parameter can also be set for multiple beams of the same TRP, which is not restrictive.
- the UE can operate in one of the first configuration and the second configuration, or can operate by combining the first configuration and the second configuration.
- the obtaining unit 101 may only obtain information of one of the first configuration and the second configuration from the base station.
- the obtaining unit 101 may obtain information of both the first configuration and the second configuration.
- the acquiring unit 101 may acquire one or more of the following: for the BLER threshold of each TRP, a first counter that counts the number of physical layer beam failures of each TRP, and the first maximum count threshold of the first counter , Used to calculate the weighting parameter of the joint BLER of the multiple TRPs, the threshold of the joint BLER, the second counter that counts the number of joint physical layer beam failures of the multiple BLERs, and the second maximum count threshold of the second counter.
- the determining unit 103 may be configured to perform the following operations in response to the first configuration and the second configuration: when one TRP of the multiple TRPs has a physical layer beam failure, increase the first counter of the TRP by 1; When the joint physical layer beam fails, the second counter is increased by 1; and when the count value of any one of the multiple first counters first reaches the first maximum count threshold, it is determined that the TRP corresponding to the first counter has a beam failure event And report to the base station. When the count value of the second counter reaches the second maximum count threshold first, it is determined that multiple TRPs have a joint beam failure event and report to the base station.
- the TRP has a physical layer beam failure
- the joint BLER of multiple TRPs is higher than the joint BLER threshold, it is considered that multiple TRPs have a joint physical layer beam. fail.
- the second counter and the multiple first counters are used to count the instances of joint beam failure and the instances of beam failure of each TRP respectively, and when any counter reaches its threshold, the base station Report the corresponding beam failure event. That is, regardless of the occurrence of a single TRP beam failure event or a joint beam failure event, the reporting unit 102 sends a report to the base station to trigger the BFR process. This can further improve the reliability of the transmission and reduce the delay.
- TRP 0 and TRP 1 The following still uses two TRPs (TRP 0 and TRP 1 ) as an example for description.
- Each TRP is configured with one reference signal (that is, corresponding to one beam).
- two first counters and one second counter will be configured to count the instances of the beam failure events of TRP 0 and TRP 1 and the instances of joint beam failure events respectively.
- These three counters work independently and are respectively denoted as Counter_0, Counter_1 and Counter_m in the following, and their corresponding maximum count thresholds are MaxCount_Num_0, MaxCount_Num_1 and MaxCount_Num_m.
- Fig. 4 shows an example of changes in the detected BLER over time.

- the solid line represents the BLER of TRP 1 (BLER 1 )
- the dash-dotted line represents the joint BLER (BLER joint )
- BLER_m on the vertical axis represents the joint BLER threshold
- BLER_s represents the BLER threshold for TRP 0 and TRP 1 .
- the BLER thresholds for the two TRPs are the same, but this is not limiting, and the two can also be different.
- the three counters do not start counting, and the determining unit 103 will not determine that a beam failure event has occurred, so the BFR process will not be triggered.
- Fig. 5 shows another example of changes in the detected BLER over time. Among them, the meaning of the coordinates and each curve is the same as that in Fig. 4, and will not be repeated here.
- the BLER 0 detected at point A exceeds the threshold BLER_s, so TRP 0 has a physical layer beam failure, and the counter Counter_0 is started and the count is increased by 1.
- MaxCount_Num_0 assuming that the count value of the counter Counter_0 reaches its first maximum count threshold MaxCount_Num_0 (Count_Num_0 in the figure represents the current value of the counter Counter_0)
- MaxCount_Num_0 in the figure represents the current value of the counter Counter_0
- Fig. 6 shows another example of changes in the detected BLER over time. Among them, the meaning of the coordinates and each curve is the same as that in Fig. 4, and will not be repeated here.
- the joint BLER exceeds the threshold BLER_m at point A, that is, a joint physical layer beam failure occurs, and the counter Counter_m is started and the count is increased by one.
- the count value of the counter Counter_m reaches the second maximum count threshold MaxCount_Num_m, it is determined that a joint beam failure event has occurred at this time, and the BFR process is triggered. Note that in the example of FIG.
- enhanced Mobile Broadband eMBB
- ultra-reliable low-latency communications Ultra Reliable Low Latnecy Communications, URLLC
- massive machine communications eMBB
- Type Communications mTTC
- eMBB can provide high-traffic mobile bandwidth services
- URLLC provides low-latency and high-reliability services.
- eMBB can be made to transmit different transport blocks to increase the transmission rate
- URLLC different TRPs can be made to transmit the same transport block to reduce transmission delay and increase reliability.
- the first configuration may be adopted.
- the URLLC scenario because different TRPs transmit the same transport block, it is possible to determine whether BFR needs to be performed based on the joint transmission performance of multiple TRPs. In addition, if a TRP has a beam failure event, BFR is executed immediately, which will further improve the transmission performance. Reliability, so the second configuration or a combination of the first configuration and the second configuration can be used.
- the base station determines the transmission scenario type, and provides the corresponding beam failure recovery configuration for the UE according to the transmission scenario type.
- the base station provides the UE with the first configuration, that is, the configuration information obtained by the obtaining unit 101 includes the first configuration; in the URLLC scenario, the base station provides the UE with the first configuration and the second configuration, that is, obtains The configuration information obtained by the unit 101 includes the first configuration and the second configuration; in the URLLC scenario, the base station provides the second configuration to the UE, that is, the configuration information obtained by the obtaining unit 101 includes the second configuration, and so on.
- the configuration information further includes information indicating the type of transmission scene, and the type of transmission scene includes one of eMBB and URLLC.
- the determining unit 103 is configured to determine, according to the indicated transmission scenario type, to report the beam failure event based on the first configuration and/or based on the second configuration. Similarly, for example, in the eMBB scenario, the beam failure event is reported based on the first configuration; in the URLLC scenario, the beam failure event is reported based on the second configuration or based on the first configuration and the second configuration.
- the BFR process also includes the identification of new candidate beams and the sending of BFRQ.
- This embodiment proposes a new way of sending BFRQ for a multi-TPR scenario.
- the reporting unit 102 is configured to report the beam failure event to the base station through a Link Recovery Request (LRR).
- LRR is a special physical layer message, carried by the physical uplink control channel (PUCCH), and is used by the UE to request an uplink grant (UL grant) from the network side so that the UE can send the physical uplink shared channel (PUSCH). Therefore, LRR is information that can be triggered by the UE at any time, and reporting beam failure events through LRR can ensure the timeliness of the report.
- the LRR may have a specific sequence format to indicate that a beam failure event has occurred.
- the specific sequence format may be, for example, a sequence of all 0s or a sequence of all 1s.
- the reporting unit 102 is also configured to send to the base station information indicating the TRP in which the beam failure event has occurred and the candidate beam information of the TRP in which the beam failure event has occurred to the base station through the MAC CE. That is, the sending of BFRQ includes two steps: one is to send a special sequence LRR indicating the occurrence of a beam failure event; the other is to send a MAC CE indicating the information of the involved TRP and the corresponding candidate beam.
- the MAC CE is, for example, carried on the PUSCH resource.
- the control resource collection pool index (CORESETPoolIndex) can be used to indicate the TRP in which the beam failure event occurs.
- CORESETPoolIndex is a concept proposed for multiple TRP scenarios and is configured on the control resource set to distinguish different TRPs with the same cell ID.
- the Scell index reported in the second step of the BFRQ process in Rel-16 is unnecessary, so these bits can be multiplexed to send the CORESETPoolIndex of the TRP where the beam failure event occurred.
- the reporting unit 102 may first send a special sequence of all 0s or all 1s to the base station, and then send the two CORESETPoolIndex corresponding to TRP 0 and TRP 1 and the information of the respective candidate beams to the base station .
- the LRR may include information indicating the TRP that the beam failure event occurred.
- CORESETPoolIndex can be used to indicate the TRP where the beam failure event occurred.
- the reporting unit 102 is also configured to send the information of the candidate beam of the TRP of the beam failure event to the base station through the MAC CE.
- the sending of BFRQ also includes two steps: one is the information of the TRP (LRR) indicating the occurrence of the beam failure event; the other is the information of the candidate beam (MAC CE) of the involved TRP.
- LRR the information of the TRP indicating the occurrence of the beam failure event
- MAC CE the information of the candidate beam
- the reporting unit 102 first carries the CORESETPoolIndex (for example, 0) corresponding to TRP 0 in the LRR and sends it to the base station, and then carries the information of the candidate beam of TRP 0 in the MAC The CE is sent to the base station.
- CORESETPoolIndex for example, 0
