图2所示为本申请实施例提供的一种波束失败恢复方法的流程图,如图2所示,本实施例提供的波束失败恢复方法包括:
步骤201、终端对网络侧设备配置的至少两个波束失败检测参考信号BFD RS集合进行测量,获得测量结果。
终端对至少两个波束失败检测参考信号(Beam Failure Detection Reference Signal,BFD RS)集合进行测量,其中,网络侧设备可通过显式或 者隐式的方式对BFD RS集合地配置,例如,显示指示方式实现中,在BFR RS集合中新增一个域指示控制资源集池索引(即控制资源集(Control resource set,CORESET)Poolindex),或控制资源组标识(CORESETGroupID);在隐式指示方式中,根据BFD RS隐式配置获取BFD RS与CORESETPoolindex或CORESETGroupID关联关系。
所述至少两个BFD RS集合包括如下至少一项:
对应相同小区的一个或者多个发射接收点TRP的BFD RS集合;
对应不同小区的一个或者多个发射接收点TRP的BFD RS集合;
对应一个或多个小区的BFD RS集合。
也就是说,所述至少两个BFD RS集合中至少存在一个BFD RS集合可以对应一个TRP或者多个TRP,和/或,所述至少两个BFD RS集合中至少存在一个BFD RS集合对应主小区中的部分TRP、或者对应辅小区中的部分TRP、或者对应主小区、或者对应辅小区、或者对应多个小区。
上述BFD RS集合对应的TRP可通过控制资源集池索引(即CORESETPoolindex),和/或控制资源组标识(CORESETGroupID)进行指示,进一步的,TRP还可通过BFD RS集合标识(即BFD RS set ID)或者NBI RS集合的标识指示。
步骤202、在根据所述测量结果,确定所述至少两个BFD RS集合满足波束失败条件的情况下,所述终端发送目标波束失败恢复请求(Beam failure recovery request,BFRQ)。
终端对所述至少两个BFD RS集合中的每个BFD RS集合进行测量,根据测量结果来判定各BFD RS集合是否发生波束失败事件。波束失败条件可为所述至少两个BFD RS集合中的一个或多个BFD RS集合发生波束失败。在所述至少两个BFD RS集合满足波束失败条件的情况下,终端向网络侧设备发送目标BFRQ。
步骤203、所述终端接收所述目标BFRQ对应的波束失败恢复响应(Beam Failure Recovery Response,BFRR)。
步骤204、所述终端根据所述目标BFRQ携带的目标波束信息对部分信道或者所有信道的传输配置指示(Transmission Configuration Indication,TCI) 状态进行重置,和/或,根据所述目标波束信息对上行功率控制的配置参数进行重置。

需要说的是,当存在可用上行资源时所述目标BFRQ包括BFR媒体接入控制(Medium Access Control,MAC)控制单元(Control Element,CE),BFR MAC CE包括发生波束失败的BFD RS集合的波束失败恢复信息;在终端当前无可用的上行链路授权,且网络侧设备配置了传输调度请求的物理上行控制信道(Physical Uplink Control Channel,PUCCH)资源的情况下,则目标BFRQ包括调度请求和BFR MAC CE;在终端当前无可用的上行链路授权且网络侧设备未配置传输调度请求的PUCCH资源的情况下,则目标BFRQ包括RACH序列、调度请求和BFR MAC CE。
以下对本申请提供的不同情况下的波束失败恢复方法进行说明。
第一种情况:所述至少两个BFD RS集合包括第一BFD RS集合和第二BFD RS集合,所述第一BFD RS集合和所述第二BFD RS集合对应第一小区的不同TRP。

步骤301、网络侧设备为终端配置至少两个波束失败检测参考信号BFD RS集合。
网络侧设备可通过显式或者隐式的方式对BFD RS集合地配置,例如,显示指示方式实现中,在BFR RS集合中新增一个域指示控制资源集池索引(即CORESETPoolindex),或控制资源组标识(CORESETGroupID);在隐式指示方式中,根据BFD RS隐式配置获取BFD RS与CORESETPoolindex或CORESETGroupID关联关系。

步骤303、所述网络侧设备发送所述目标BFRQ对应的波束失败恢复响应BFRR,使得终端根据所述目标BFRQ携带的目标波束信息对部分信道或者所有信道的传输配置指示(Transmission Configuration Indication,TCI)状态进行重置,和/或,根据所述目标波束信息对上行功率控制的配置参数进行重置。
本实施例中,网络侧设备为终端配置至少两个波束失败检测参考信号BFD RS集合;接收目标波束失败恢复请求BFRQ;发送所述目标BFRQ对应的波束失败恢复响应BFRR,使得终端根据所述目标BFRQ携带的目标波束信息对部分信道或者所有信道的传输配置指示(Transmission Configuration Indication,TCI)状态进行重置,和/或,根据所述目标波束信息对上行功率控 制的配置参数进行重置。上述过程可使得网络侧设备和终端能够快速恢复被中断的波束链路,提高数据传输的可靠性。
