下面结合附图，通过一些实施例及其应用场景对本申请实施例提供的终端配置的去激活方法进行详细地说明。
如图2所示，本申请实施例提供了一种波束失败恢复处理方法，包括：
步骤201：在满足调度请求SR触发条件的情况下，终端按照预设方式触发并发送SR。
本步骤中，触发的SR可以是现有技术中的SR，也可以是专用于波束失败恢复的SR，如专用SR(dedicated SR)，该dedicated SR用于通知网络将有波束失败恢复请求信息发送给网络，也即该dedicated SR用于触发发送MAC CE for束失败恢复请求(BFR Request，BFRQ)的上行资源，且所述dedicated SR也可用于其他逻辑信道的共享，且本步骤中的SR处于挂起(pending)状态。
步骤202：终端根据网络侧分配的可用上行资源的大小，按照预设格式生成包含波束失败恢复信息的MAC CE，并在所述可用上行资源上按照预设优先级规则传输所述MAC CE和第一上行信息中的至少一项，所述可用上行资源是网络侧根据所述SR分配的。
本步骤中，上述可用上行资源可为专用SR(dedicated SR)触发的上行资源，即网络接收到dedicated SR后通过下行控制信息(Downlink Control Information，DCI)指示的上行资源。
具体的，上述第一上行信息为可用上行资源对应的上行信息，在所述第 一上行信息与上述MAC CE发生冲突时，按照上述预设优先级规则确定所述可用上行资源上传输的信息，如，根据上述预设优先级规则可对第一上行信息或MAC CE进行复用或者丢弃。
这里，上述冲突可以是指上述第一上行信息对应的上行资源与包含波束失败恢复信息的MAC CE对应的上行资源存在全部或部分重叠。上述丢弃是指发送高优先级的信息，丢弃低优先级的信息；上述复用是指根据优先级关系等，确定上行资源能够承载的上行信息，并在上行资源发送这些上行信息，对于无法承载的较低优先级的上行信息，则丢弃掉。另外，在确定复用的上行信息时，还可以依据上行资源的大小、上行信息的大小等因素进行确定。
在本申请实施例中，在满足调度请求SR触发条件的情况下，终端按照预设方式触发并发送SR，网络侧根据所述SR分配可用上行资源，终端根据网络侧分配的可用上行资源的大小，按照预设格式生成包含波束失败恢复信息的MAC CE，并在所述可用上行资源上按照预设优先级规则传输所述MAC CE和第一上行信息中的至少一项，从而实现了多TRP场景中发生波束失败时触发、发送SR以及传输上述MAC CE和第一上行信息的目的。
可选地，所述第一上行信息包括以下至少一项：
上行控制信道对应的数据或由小区无线网络临时标识(Cell Radio Network Temporary Identifier，C-RNTI)加扰的MAC CE(C-RNTI MAC CE or data from UL-CCCH)；
包含配置授权确认信息的MAC CE(Configured Grant Confirmation MAC CE)；
包含波束失败恢复信息的MAC CE(BFR MAC CE)；
包含多个配置授权确认信息的MAC CE(Multiple Entry Configured Grant Confirmation MAC CE)；
包含副链路配置授权确认信息的MAC CE(Sidelink Configured Grant Confirmation MAC CE)；
用于报告不含填充的缓冲状态的MAC CE(MAC CE for BSR,with  exception of BSR included for padding)；
包含一个功率余量报告信息的MAC CE或者包含多个功率余量报告信息的MAC CE(Single Entry PHR MAC CE or Multiple Entry PHR MAC CE)；
除上行控制信道之外的逻辑信道的数据(data from any Logical Channel,except data from UL-CCCH)；
用于推荐比特率查询的MAC CE(MAC CE for Recommended bit rate query)；
用于报告含有填充的缓冲状态的MAC CE(MAC CE for BSR included for padding)。
可选地，所述预设优先级关系包括以下至少一项：
上行控制信道对应的数据或由小区无线网络临时标识C-RNTI加扰的MAC CE的优先级高于所述MAC CE的优先级；
第一MAC CE的优先级高于第二MAC CE的优先级，所述第一MAC CE为包含高优先级TRP对应的波束失败恢复信息的MAC CE，所述第二MAC CE为包含低优先级TRP对应的波束失败恢复信息的MAC CE；
第三MAC CE的优先级高于第四MAC CE的优先级，所述第三MAC CE为与高优先级SR关联的MAC CE，所述第四MAC CE为与低优先级关联SR的MAC CE；
第五MAC CE的优先级高于第六MAC CE的优先级，所述第五MAC CE为包含主小区中部分TRP或所有TRP的波束失败恢复信息的MAC CE，所述第六MAC CE为包含辅小区中部分TRP或所有TRP的波束失败恢复信息的MAC CE；
第七MAC CE的优先级高于第八MAC CE的优先级，所述第七MAC CE为包含发生小区波束失败事件的辅小区的波束失败恢复信息的MAC CE，所述第八MAC CE为包含部分TRP发生波束失败事件的辅小区的波束失败恢复信息的MAC CE。
此外，上述MAC CE和第一上行信息的优先级规则可复用于以下几种情 况：
在发生波束失败时便存在可用上行资源的情况，在此情况下终端直接在上行资源上发送上述MAC CE，不会触发波束失败恢复调度请求；
在发生波束失败时若不存在用于传输SR for BFR的物理上行控制信道(Physical Uplink Control Channel，PUCCH)资源，此时通过随机接入信道(Random Access Channel，RACH)进行BFR，上述MAC CE在Msg3中或者随机接入后的数据传输调度中进行传输。

至少存在一个第一小区的部分发送接收点TRP发生波束失败事件；
至少存在一个第二小区的所有TRP均发生波束失败事件；
所述终端生成了包含至少一个TRP或小区的波束失败恢复信息的媒体接入控制单元MAC CE。

本申请实施例中，波束失败事件是指终端检测到波束失败检测(Beam Failure Detection，BFD)参考信号(Reference Signal，RS)，若一个BFD RS集合中的所有BFD RS的测量值在一个时间窗内一直低于网络侧预设的门限值，物理层向MAC层上报所述BFD RS集合的波束失败指示，MAC层在收到所述BFD RS集合的波束失败指示后，与所述BFD RS集合对应的波束失败统计计数器的值加1。当与所述BFD RS集合对应的波束失败统计计数器的数值大于网络配置的阈值后，MAC层将宣布所述BFD RS集合关联的TRP或小区发生波束失败事件。
本申请实施例中，网络配置多个BFD RS集合，其中，每个BFD RS集合对应一个TRP。
本申请实施例中的TRP通过以下至少一项表示：
波束失败检测参考信号(BFD RS)集合标识；
新波束标识(New Beam Identification，NBI)参考信号集合标识；
控制资源池索引(CORESET Pool index)；
控制资源组标识(CORESET Group ID)。

其中，所述第一SR为根据SR与TRP的关联关系确定的与第一TRP对应的SR，所述第一TRP为发生波束失败事件的TRP或者未发生波束失败事件的TRP；或者，所述第一SR为所有网络侧配置的TRP波束失败恢复调度 请求；
所述第二SR为辅小区波束失败恢复调度请求(SR for SCell BFR)；
所述第一SR和第二SR可相同。
本申请实施例中，网络侧配置SR与TRP的关联关系，其中，SR与TRP的关联关系包括如下一种：

可选地，所述终端根据上行请求资源优先级规则，触发SR，包括：
在网络侧设备未配置第一传输资源的情况下，触发SR；
其中，所述第一传输资源对应的传输优先级高于所述SR对应的传输资源的传输优先级。

实施例四：
配置多个SR for BFR，每个SR中配置一个PUCCH资源，一个高层参数组和一个高层操作工具，且一个SR与一个BFD RS集合关联。
当一个BFD RS集合检测失败时，选择与失败的BFD RS集合或者未检测到失败的一个BFD RS集合关联的SR，按照其对应的配置参数组和高层操作工作组进行发送。
实施例五：
仅配置一个SR for BFR，该SR中配置多个PUCCH资源，至少一个高层参数组和至少一个高层操作工具组，且一个PUCCH资源与一个BFD RS集合关联。
当BFD RS集合检测失败时，选择与失败的BFD RS集合或者未失败的一个BFD RS集合关联的PUCCH资源发送SR，所有PUCCH资源用至少一个高层参数组和至少一个高层操作工具组。具体实施的方式至少包括以下三种：

每个PUCCH资源按照配置的高层参数组发送SR，且SR禁止传输定时器和SR计数器以PUCCH资源为单位进行操作，若一个BFD RS集合检测失败，则发送与所述发生波束失败的BFD RS集合关联的PUCCH。在所述PUCCH资源发送后，开启其对应的SR禁止传输定时器，且在定时器结束之前，禁止发送与所述发生波束失败的BFD RS集合关联的PUCCH，但可发送网络配置的其它用于传输波束失败恢复调度请求的PUCCH资源，且所述PUCCH资源对应的SR传输计数器的值加1。当所述SR传输计数器的值大于网络配置的与所述BFD RS集合关联的PUCCH资源的SR最大传输次数时，则取消对应pending SR。
第二种：多个高层参数组(除周期和时隙偏置外，所述多套高层参数组中的其余参数可分别共用一个数值)、多个SR禁止传输定时器和一个SR传输计数器；
每个PUCCH资源按照配置的高层参数组发送SR，SR禁止传输定时器以PUCCH资源为单位进行操作，但SR传输计数器统计与所述SR关联的所有PUCCH资源的传输次数。若一个BFD RS集合检测失败，则发送与所述发生波束失败的BFD RS集合关联的PUCCH。在所述PUCCH资源发送后，则开启其对应的SR禁止传输定时器，在SR禁止传输定时器结束之前，禁止发送与所述发生波束失败的BFD RS集合关联的PUCCH，但可发送网络配置的其它用于传输波束失败恢复调度请求的PUCCH资源，且整体SR传输计数器的值加1。当所述整体SR传输计数器的值大于网络配置的SR最大传输次 数时，则取消对应pending SR。
第三种：多个高层参数组(除周期和时隙偏置外，所述多套高层参数组中的其余参数可分别共用一个数值)，一个SR传输计数器，一个SR禁止传输定时器，存在以下两种方式：
方式1：每个PUCCH资源按照配置的高层参数组发送SR，但SR禁止传输定时器和SR计数器统计与所述SR关联的所有PUCCH资源相关，即当发送任一PUCCH时，若SR禁止传输定时器处于关闭状态，则开启SR禁止传输定时器，且在SR禁止传输定时器结束之前，禁止发送所有PUCCH资源；且SR传输计数器的值加1。当整体SR传输计数器的值大于网络配置的SR最大传输次数时，则取消对应pending SR；
方式2：每个PUCCH资源按照配置的高层参数组发送SR，但SR禁止传输定时器和SR传输计数器统计以所述SR关联的所有PUCCH资源为单位进行，即若在所有PUCCH资源的最大周期内发送了传输SR的PUCCH，则SR禁止传输定时器在PUCCH资源最大周期内的上述第一时间开启；所述SR传输计数器在上述目标符号之后统计计数：在所述周期内，若发送了至少一个PUCCH资源，则SR传输计数器的值增加1。当所述SR传输计数器的值大于网络配置的SR最大传输次数时，则取消对应pending SR。具体时序图如下。
如图7所示，一个SR共关联4个PUCCH资源，且4个PUCCH周期相同，但4个PUCCH资源对应的上述周期与时隙偏置不同，若在周期T中发送了PUCCH#2，则在最后一个资源PUCCH#4的最后一个符号后的第一个符号开启SR禁止传输定时器，同时SR传输计数器的值加1。同理，也可在最大周期结束后的第一个符号开启SR禁止传输定时器，同时SR传输计数器的值加1。

AC域指示关联发生波束失败的BFD RS集合的新波束识别过程是否完成；
R域为保留比特；
Candidate RS ID为新波束在候选波束列表的标识。
其中，当C i和C j为“11”时，对应两行含AC域的字段，其中，i＝1、2、3、4、5、6或7，j＝9、10、11、12、13、14或15；当SP0和SP1为“11”，SpCell的波束失败恢复信息对应第一行含AC域的字段。
实施例八：
1个MAC CE可携带部分发生波束失败的BFD RS集合对应的波束失败恢复信息，所述部分发生波束失败的BFD RS集合的集合标识相同，或者关联同一个控制资源集池索引(CORESET Pool index)。
该实施例中，C i的排列不再按照网络配置的SCell列表，而是根据当前Cell对应的BFD RS集合进行排列，其中，i表示C i对应的小区标识。如图9所示，假设此BFR MAC CE只携带第二个BFD RS集合的波束失败恢复信息，由于SCell#3和SCell#4只配置了一个BFD RS集合(第一个BFD RS集合)，因此其小区标识不会出现在比特映射序列中。
