[0032] The following describes in detail the terminal configuration deactivation method provided by the embodiment of the present application through some embodiments and their application scenarios in combination with the accompanying drawings.

[0033] like Figure 2 As shown, an embodiment of the present application provides a beam failure recovery processing method, including:

[0034] Step 201: When a scheduling request SR triggering condition is met, the terminal triggers and sends the SR in a preset manner.

[0035] In this step, the triggered SR can be the SR in the prior art, or it can be an SR dedicated to beam failure recovery, such as a dedicated SR. The dedicated SR is used to notify the network that a beam failure recovery request information will be sent to the network, that is, the dedicated SR is used to trigger the uplink resource of sending MAC CE for BFRQ, and the dedicated SR can also be used for sharing other logical channels, and the SR in this step is in a pending state.

[0036] Step 202: The terminal generates a MAC CE containing beam failure recovery information in a preset format according to the size of the available uplink resources allocated by the network side, and transmits the MAC CE and at least one of the first uplink information on the available uplink resources according to a preset priority rule. The available uplink resources are allocated by the network side according to the SR.

[0037] In this step, the available uplink resources may be uplink resources triggered by a dedicated SR (dedicated SR), that is, uplink resources indicated by the network through DCI after receiving the dedicated SR.

[0038] Specifically, the above-mentioned first uplink information is the uplink information corresponding to the available uplink resources. When the first uplink information conflicts with the above-mentioned MAC CE, the information transmitted on the available uplink resources is determined according to the above-mentioned preset priority rules. For example, the first uplink information or MAC CE can be multiplexed or discarded according to the above-mentioned preset priority rules.

[0039] Here, the above-mentioned conflict may refer to the complete or partial overlap between the uplink resource corresponding to the above-mentioned first uplink information and the uplink resource corresponding to the MAC CE containing beam failure recovery information. The above-mentioned discarding refers to sending high-priority information and discarding low-priority information; the above-mentioned multiplexing refers to determining the uplink information that can be carried by the uplink resources based on priority relationships, etc., and sending this uplink information on the uplink resources, and discarding the lower-priority uplink information that cannot be carried. In addition, when determining the uplink information to be multiplexed, it can also be determined based on factors such as the size of the uplink resources and the size of the uplink information.

[0040] In an embodiment of the present application, when the scheduling request SR triggering condition is met, the terminal triggers and sends the SR in a preset manner, the network side allocates available uplink resources according to the SR, and the terminal generates a MAC CE containing beam failure recovery information in a preset format according to the size of the available uplink resources allocated by the network side, and transmits at least one of the MAC CE and the first uplink information on the available uplink resources according to the preset priority rules, thereby achieving the purpose of triggering, sending SR and transmitting the above-mentioned MAC CE and first uplink information when beam failure occurs in a multi-TRP scenario.

[0041] Optionally, the first uplink information includes at least one of the following:

[0042] Data corresponding to the uplink control channel or MAC CE scrambled by the cell radio network temporary identifier C-RNTI (C-RNTI MAC CE or data from UL-CCCH);

[0043] MAC CE containing configuration authorization confirmation information (Configured Grant Confirmation MAC CE);

[0044] MAC CE containing beam failure recovery information (BFR MAC CE);

[0045] MAC CE containing multiple configured authorization confirmation information (Multiple Entry Configured GrantConfirmation MAC CE);

[0046] MAC CE containing the sidelink configured grant confirmation information (Sidelink Configured Grant Confirmation MAC CE);

[0047] MAC CE for BSR, with exception of BSR included for padding;

[0048] A MAC CE containing one power headroom report information or a MAC CE containing multiple power headroom report information (Single Entry PHR MAC CE or Multiple Entry PHR MAC CE);

[0049] Data from any Logical Channel, except data from UL-CCCH;

[0050] MAC CE for Recommended bit rate query;

[0051] MAC CE for BSR included for padding (MAC CE for BSR included for padding) is used to report the buffer status including padding.

[0052] Optionally, the preset priority relationship includes at least one of the following:

[0053] The priority of the data corresponding to the uplink control channel or the MAC CE scrambled by the cell radio network temporary identifier C-RNTI is higher than the priority of the MAC CE;

[0054] The priority of the first MAC CE is higher than the priority of the second MAC CE. The first MAC CE is a MAC CE including beam failure recovery information corresponding to a high-priority TRP, and the second MAC CE is a MAC CE including beam failure recovery information corresponding to a low-priority TRP.

[0055] The priority of the third MAC CE is higher than the priority of the fourth MAC CE, the third MAC CE is a MAC CE associated with a high-priority SR, and the fourth MAC CE is a MAC CE associated with a low-priority SR;

[0056] The priority of the fifth MAC CE is higher than the priority of the sixth MAC CE, the fifth MAC CE is a MAC CE including beam failure recovery information of some TRPs or all TRPs in the primary cell, and the sixth MAC CE is a MAC CE including beam failure recovery information of some TRPs or all TRPs in the secondary cell;

[0057] The priority of the seventh MAC CE is higher than the priority of the eighth MAC CE. The seventh MAC CE is a MAC CE containing the beam failure recovery information of the secondary cell where a cell beam failure event occurs, and the eighth MAC CE is a MAC CE containing the beam failure recovery information of the secondary cell where a beam failure event occurs in some TRPs.

[0058] In addition, the above-mentioned priority rules for MAC CE and first uplink information can be reused in the following situations:

[0059] When beam failure occurs, there are available uplink resources. In this case, the terminal directly sends the above MAC CE on the uplink resources, and does not trigger a beam failure recovery scheduling request.

[0060] If there is no PUCCH resource for transmitting SR for BFR when beam failure occurs, BFR is performed through RACH. The above MAC CE is transmitted in Msg3 or in the data transmission scheduling after random access.

[0061] Optionally, the SR triggering condition includes at least one of the following:

[0062] A beam failure event occurs in some transmission reception points TRPs of at least one first cell;

[0063] All TRPs with at least one secondary cell experience a beam failure event;

[0064] The terminal generates a media access control element MAC CE including beam failure recovery information of at least one TRP or cell.

[0065] Specifically, the SR triggering condition includes at least one of the following:

[0066] Within the preset time window, a beam failure event occurs in some transmission reception points TRPs of at least one first cell;

[0067] Within the preset time window, all TRPs with at least one second cell experience a beam failure event;

[0068] The terminal generates a media access control element MAC CE including beam failure recovery information of at least one TRP or cell.

[0069] In an embodiment of the present application, a beam failure event refers to a terminal detecting a beam failure detection (BFD) reference signal (RS). If the measurement values ​​of all BFD RSs in a BFD RS set are always lower than a threshold value preset by the network side within a time window, the physical layer reports a beam failure indication of the BFD RS set to the MAC layer. After receiving the beam failure indication of the BFD RS set, the MAC layer adds 1 to the value of the beam failure statistical counter corresponding to the BFD RS set. When the value of the beam failure statistical counter corresponding to the BFD RS set is greater than the threshold configured by the network, the MAC layer will declare that a beam failure event has occurred in the TRP or cell associated with the BFD RS set.

[0070] In an embodiment of the present application, the network is configured with multiple BFD RS sets, where each BFD RS set corresponds to a TRP.

[0071] The TRP in the embodiments of the present application is represented by at least one of the following:

[0072] Beam Failure Detection Reference Signal (BFD RS) set identifier;

[0073] NBI reference signal set identifier;

[0074] Control resource pool index (CORESET Pool index);

[0075] Control resource group identifier (CORESET Group ID).

[0076] The beam failure recovery processing method of the embodiment of the present application is that when the scheduling request SR triggering condition is met, the terminal triggers the SR in a preset manner. For example, when a beam failure event occurs in at least some transmission receiving points TRP of a first cell within a preset time window, the SR is triggered in a preset manner; or, when a beam failure event occurs in all TRPs of at least one second cell within a preset time window, the SR is triggered in a preset manner; or, when the terminal generates a media access control unit MAC CE containing beam failure recovery information of at least one TRP or cell, the SR is triggered in a preset manner, thereby achieving the purpose of triggering SR in a multi-TRP scenario.

[0077] Optionally, the terminal triggers the SR in a preset manner, including:

[0078] Trigger SR at the first opportunity;

[0079] Alternatively, the terminal triggers an SR according to an uplink request resource priority rule;

[0080] The first time includes one of the following:

[0081] A time that is after a preset time window, where the preset time window is configured by the network;

[0082] The time after a beam failure event occurs in any TRP of the first cell;

[0083] The time after a beam failure event occurs for all TRPs of the second cell.

[0084] Optionally, the terminal triggering the SR at the first time includes:

[0085] The terminal triggers a first SR at a first time;

[0086] Alternatively, the terminal triggers the second SR at the first time;

[0087] The first SR is an SR corresponding to the first TRP determined according to the association relationship between the SR and the TRP, and the first TRP is a TRP in which a beam failure event occurs or a TRP in which no beam failure event occurs; or the first SR is a TRP beam failure recovery scheduling request configured on all network sides;

[0088] The second SR is a secondary cell beam failure recovery scheduling request (SR for SCell BFR);

[0089] The first SR and the second SR may be the same.

[0090] In the embodiment of the present application, the network side configures the association relationship between the SR and the TRP, wherein the association relationship between the SR and the TRP includes the following:

[0091] One SR is associated with multiple PUCCH resources, where one PUCCH resource is associated with one TRP;

[0092] One SR is associated with one PUCCH resource, and each SR is associated with one TRP.

[0093] In an embodiment of the present application, the uplink request resource priority rule may be the priority of non-competitive random access (CFRA) resources > the priority of scheduling request resources > the priority of competitive random access (CBRA) resources; wherein, CFRA resources are associated with TRP, and CBRA resources are associated with TRP.

[0094] Optionally, before the terminal triggers the second SR for the first time, the terminal further includes:

[0095] In the second cell where beam failure occurs in all TRPs, all pending SRs associated with the TRPs in the second cell are canceled, and the corresponding SR transmission prohibition timers are stopped.

[0096] In an embodiment of the present application, when beam failure occurs in all TRPs of at least one cell, the pending SRs associated with all TRPs of the cell are canceled, and all corresponding SR prohibit transmission timers (SR-ProhibitTimer) are stopped, and the SR for SCell BFR is directly triggered, or the SR is triggered according to the above-mentioned uplink request resource priority rules.

[0097] Optionally, the terminal triggers an SR according to an uplink request resource priority rule, including:

[0098] When the network side device is not configured with the first transmission resource, triggering the SR;

[0099] The transmission priority corresponding to the first transmission resource is higher than the transmission priority of the transmission resource corresponding to the SR.

[0100] Specifically, if the network is configured with CFRA resources, SR is not triggered; otherwise, SR is triggered; or, if the network is not configured with CFRA resources and SR transmission resources, a beam failure recovery request is sent through CBRA resources.

[0101] The above-mentioned process of triggering SR is described below with reference to specific embodiments.

[0102] Example 1:

[0103] Within the preset time window, all TRPs have beam failure events, and each TRP triggers the corresponding SR when a beam failure event occurs. Figure 3 As shown, there are four TRPs, namely TRP1, TRP2, TRP3 and TRP4, among which TRP1 corresponds to SR1, TRP2 corresponds to SR2, TRP3 corresponds to SR3, and TRP4 corresponds to SR4. SR1, SR2, SR3 and SR4 can be the same, that is, SR1, SR2, SR3 and SR4 are the same SR, or SR4 can also be a secondary cell beam failure recovery scheduling request (SR for SCell BFR).

[0104] Example 2:

[0105] Within the preset time window, all TRPs have beam failure events, and each TRP triggers the corresponding SR after the preset time window ends, such as Figure 4 As shown, there are four TRPs, namely TRP1, TRP2, TRP3 and TRP4, among which TRP1 corresponds to SR1, TRP2 corresponds to SR2, TRP3 corresponds to SR3, and TRP4 corresponds to SR4. SR1, SR2, SR3 and SR4 can be the same, that is, SR1, SR2, SR3 and SR4 are the same SR, or SR4 can also be a secondary cell beam failure recovery scheduling request (SR for SCell BFR).

[0106] Example 3:

[0107] Within the preset time window, all TRPs have beam failure events. After all TRPs have beam failure events or after the preset time window ends, all pending SRs are canceled and the secondary cell beam failure recovery scheduling request is triggered. Figure 5 and Figure 6As shown in the figure, there are four TRPs: TRP1, TRP2, TRP3, and TRP4. TRP1 corresponds to SR1, TRP2 corresponds to SR2, TRP3 corresponds to SR3, and TRP4 corresponds to SR4. When a beam failure event occurs in TRP1, TRP2, and TRP3, each triggers the corresponding SR, namely SR1, SR2, and SR3, respectively. If a beam failure event occurs in TRP4, all pending SRs are canceled, and SR for SCell BFR is triggered. Alternatively, if a beam failure event occurs in TRP4, all pending SRs are canceled after the preset window ends, and SR for SCell BFR is triggered.

[0108] Optionally, the terminal sending the SR includes:

[0109] The terminal periodically sends the SR.

[0110] Optionally, the terminal sending the SR includes:

[0111] The terminal sends the SR through a second transmission resource associated with the SR according to a network-configured parameter group and a network-defined high-level operation tool group;

[0112] The second transmission resource includes at least one of the following:

[0113] Physical uplink control channel (PUCCH) resources associated with the SR;

[0114] A PUCCH resource associated with the TRP where the beam failure event occurs among the multiple PUCCH resources associated with the SR;

[0115] The PUCCH resources associated with the TRP in which no beam failure event occurs among the multiple PUCCH resources associated with the SR.

[0116] Optionally, the parameter group includes at least one of the following:

[0117] Maximum number of SR transmissions;

[0118] Cycle and time slot offset, where the cycle and time slot offset indicate two parameters: cycle and time slot offset. The cycle refers to the SR transmission period, and the time slot offset refers to the offset of the actual start time of SR transmission relative to the start position of the cycle.

[0119] The length of the SR prohibition period;

[0120] And / or, the high-level operation tool set includes at least one of the following:

[0121] SR transmission counter;

[0122] SR prohibit transmission timer.

[0123] Optionally, in a case where the SR corresponds to a parameter group and a higher-layer operation tool group, one or more PUCCH resources associated with the SR share the parameter group and the higher-layer operation tool group.

[0124] Optionally, in a case where the SR corresponds to multiple parameter groups and one higher layer operation tool group, multiple PUCCH resources associated with the SR share the higher layer operation tool group;

[0125] Alternatively, in a case where the SR corresponds to multiple parameter groups and multiple higher layer operation tool groups, the multiple PUCCH resources associated with the SR correspond to different higher layer operation tool groups and different parameter groups, respectively;

[0126] The periods and time slot offsets in the multiple parameter groups corresponding to the SR are different.

[0127] For example, multiple parameter groups are configured, each parameter group includes only the period and time slot offset, and the period and time slot offset in different parameter groups are different. Furthermore, a maximum number of SR transmissions and a length of the SR prohibited transmission time are configured. Multiple PUCCH resources associated with the SR can share the maximum number of SR transmissions and the length of the SR prohibited transmission time.

[0128] For another example, multiple parameter groups are configured, each parameter group includes three parameters (maximum SR transmission times, cycle and time slot offset, and length of SR prohibited transmission time). Among them, the cycle and time slot offset in some parameter groups are different, and the first parameter in all parameter groups can be configured to the same value.

[0129] In a case where multiple PUCCH resources associated with the SR share the higher layer operation tool group, the SR transmission prohibition timer is started at a first time within a maximum period of the PUCCH resource, where the first time is a time corresponding to a first symbol after a target symbol, and the target symbol is a last symbol of a last PUCCH resource among the multiple PUCCH resources within the maximum period of the PUCCH resource;

[0130] and / or, when multiple PUCCH resources associated with the SR share the higher layer operation tool group, the SR transmission counter counts after the target symbol; wherein, within the maximum period of the PUCCH resource, if at least one PUCCH resource is transmitted, the value of the SR transmission counter is incremented by 1;

[0131] The maximum PUCCH resource period is the maximum value of the periods of the multiple PUCCH resources.

[0132] The following describes the details in conjunction with specific embodiments.

[0133] Example 4:

[0134] Configure multiple SRs for BFR. Each SR is configured with a PUCCH resource, a high-layer parameter group, and a high-layer operation tool. One SR is associated with one BFD RS set.

[0135] When a BFD RS set fails to be detected, the SR associated with the failed BFD RS set or a BFD RS set that has not been detected to have failed is selected and sent according to its corresponding configuration parameter group and high-level operation work group.

[0136] Embodiment 5:

[0137] Only one SR for BFR is configured, in which multiple PUCCH resources, at least one high-layer parameter group and at least one high-layer operation tool group are configured, and one PUCCH resource is associated with one BFD RS set.

[0138] When the BFD RS set detection fails, the PUCCH resource associated with the failed BFD RS set or a non-failed BFD RS set is selected to send the SR. All PUCCH resources use at least one high-level parameter group and at least one high-level operation tool group. The specific implementation methods include at least the following three:

[0139] The first type: multiple high-level parameter groups, multiple SR transmission prohibition timers, and multiple SR transmission counters (except for the period and slot offset, the remaining parameters in the multiple high-level parameter groups can share the same value);

[0140] Each PUCCH resource sends an SR according to the configured high-level parameter group, and the SR prohibit transmission timer and SR counter operate in units of PUCCH resources. If a BFD RS set fails to be detected, the PUCCH associated with the BFD RS set where the beam failure occurred is sent. After the PUCCH resource is sent, the corresponding SR prohibit transmission timer is started, and before the timer expires, the PUCCH associated with the BFD RS set where the beam failure occurred is prohibited from being sent. However, other PUCCH resources configured by the network for transmitting beam failure recovery scheduling requests can be sent, and the value of the SR transmission counter corresponding to the PUCCH resource is increased by 1. When the value of the SR transmission counter is greater than the maximum number of SR transmissions for the PUCCH resource associated with the BFD RS set configured by the network, the corresponding pending SR is canceled.

[0141] The second type: multiple high-level parameter groups (except for the period and slot offset, the remaining parameters in the multiple high-level parameter groups can share the same value), multiple SR prohibition transmission timers and one SR transmission counter;

[0142] Each PUCCH resource sends an SR according to the configured high-level parameter group. The SR prohibit transmission timer operates in units of PUCCH resources, but the SR transmission counter counts the number of transmissions of all PUCCH resources associated with the SR. If a BFD RS set fails to detect, the PUCCH associated with the BFD RS set where the beam failure occurred is sent. After the PUCCH resource is sent, the corresponding SR prohibit transmission timer is started. Before the SR prohibit transmission timer ends, the PUCCH associated with the BFD RS set where the beam failure occurred is prohibited from being sent, but other PUCCH resources configured by the network for transmitting beam failure recovery scheduling requests can be sent, and the value of the overall SR transmission counter is increased by 1. When the value of the overall SR transmission counter is greater than the maximum number of SR transmissions configured by the network, the corresponding pending SR is canceled.

[0143] The third method is to use multiple high-level parameter groups (except for the period and slot offset, the remaining parameters in the multiple high-level parameter groups can share the same value), an SR transmission counter, and an SR transmission prohibition timer. There are two methods:

[0144] Method 1: Each PUCCH resource sends an SR according to the configured high-level parameter group, but the SR prohibit transmission timer and SR counter statistics are related to all PUCCH resources associated with the SR. That is, when sending any PUCCH, if the SR prohibit transmission timer is in the off state, the SR prohibit transmission timer is turned on, and all PUCCH resources are prohibited from being sent before the SR prohibit transmission timer ends; and the value of the SR transmission counter is increased by 1. When the value of the overall SR transmission counter is greater than the maximum number of SR transmissions configured by the network, the corresponding pending SR is canceled;

[0145] Mode 2: Each PUCCH resource sends an SR according to the configured high-level parameter group, but the SR transmission prohibition timer and SR transmission counter are counted in units of all PUCCH resources associated with the SR, that is, if a PUCCH transmitting an SR is sent within the maximum period of all PUCCH resources, the SR transmission prohibition timer is turned on at the first time within the maximum period of the PUCCH resource; the SR transmission counter counts after the target symbol: within the period, if at least one PUCCH resource is sent, the value of the SR transmission counter increases by 1. When the value of the SR transmission counter is greater than the maximum number of SR transmissions configured by the network, the corresponding pending SR is canceled. The specific timing diagram is as follows. Figure 7 As shown in the figure, an SR is associated with four PUCCH resources, and the four PUCCH periods are the same, but the periods and slot offsets corresponding to the four PUCCH resources are different. If PUCCH#2 is sent in period T, the SR prohibit transmission timer is started in the first symbol after the last symbol of the last resource PUCCH#4, and the SR transmission counter value is incremented by 1. Similarly, the SR prohibit transmission timer can also be started in the first symbol after the end of the maximum period, and the SR transmission counter value is incremented by 1.
