背景技术
在高频段通信系统中，由于无线信号的波长较短，较容易发生信号传播被阻挡等情况，导致信号传播中断，因此目前在波束赋形的波束测量机制上引入波束失败恢复机制。波束失败恢复机制中，网络侧设备为用户侧设备(User Equipment，UE)配置波束失败检测参考信号(Beam Failure Detection Reference Signal，BFD RS)资源，UE根据配置的BFD RS资源对BFD RS进行测量，并在确定发生波束失败事件后，向网络侧设备上报波束失败恢复请求，以便于进行波束失败恢复。
相关技术中，BFD RS资源由网络侧设备进行配置，然而，在网络侧设备没有为UE配置BFD RS资源的情况下，UE如何确定BFD RS资源还没有得到解决。

下面将结合本公开实施例中的附图，对本公开实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本公开一部分实施例，而不是全部的实施例。基于本公开中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本公开保护的范围。说明书以及权利要求中使用“和/或”表示连接对象至少其中之一。

本公开一实施例提供了一种确定BFD RS资源的方法，该方法应用于UE，可以由UE执行。图1为本公开一实施例提供的确定BFD RS资源的方法的流程示意图，如图1所示，该方法包括：
步骤102，在未被配置用于进行BFD RS测量的BFD RS资源时，根据CORESET的TCI状态，确定BFD RS资源。
通过本公开实施例，用户侧设备在未被配置用于进行BFD RS测量的BFD RS资源时，可以根据CORESET的TCI状态，确定BFD RS资源，从而便于用户侧设备进行波束失败检测以及波束失败恢复，避免用户侧设备因无法进行波束失败检测和波束失败恢复而需要执行无线链路失败与重建过程的问题，减少用户侧设备恢复数据传输所需的时延，提升通信系统的数据传输性能。
本实施例中，TCI状态用于指示RS集合，相应地，上述步骤102中，根据CORESET的TCI状态，确定BFD RS资源，具体为：根据TCI状态指示的RS集合，确定BFD RS资源。
本实施例中，RS集合包括至少一个RS索引和该RS索引对应的QCL类型，相应地，上述根据TCI状态指示的RS集合，确定BFD RS资源，具体 为：
(1)将RS集合中对应的QCL类型为指定QCL类型的RS索引，确定为BFD RS资源索引；
(2)根据BFD RS资源索引，确定BFD RS资源。
表1为本公开一实施例提供的TCI状态与RS集合的对应关系示意表，如表1所示，不同的TCI状态对应有不同的RS集合。本公开实施例中TCI状态可以指示一个或多个RS集合，这里不做限制。
表1
TCI状态 RS集合
状态1 集合A
状态2 集合B
表2为本公开一实施例提供的RS集合所包括的具体内容的示意表，如表2所示，RS集合中包括至少一个RS索引和该RS索引对应的QCL类型。
表2
Figure PCTCN2019077652-appb-000001
RS集合中包含的RS索引的数量为至少一个，其数量上限本实施例不做限定。
以表1表2为例，本实施例中，在RS集合中，将对应的QCL类型为指定QCL类型的RS索引，确定为BFD RS资源索引，然后根据BFD RS资源索引，确定BFD RS资源。
一个具体的实施方式中，指定QCL类型包括：类型D，也即type D，则上述表1表2中，将CSI-RS资源索引2(CSI-RS resource index 2)确定为BFD RS资源索引，然后根据BFD RS资源索引，确定BFD RS资源。
进一步地，本实施例中，在确定BFD RS资源后，还将上述指定QCL类型对应的QCL参数，确定为BFD RS资源的QCL参数。
一个实施例中，上述指定QCL类型包括：类型D，则上述指定QCL类型对应的QCL参数包括：空间接收参数(Spatial Rx parameter)。因此，BFD  RS资源的QCL参数包括空间接收参数。
一个实施例中，空间接收参数至少包括以下一项：
AoA、主导AoA(Dominant AoA)、平均AoA(average AoA)、AoA的功率角度谱(Power Angular Spectrum of AoA，PAS of AoA)、平均AoD(average AoD)、AoD的功率角度谱(Power Angular Spectrum of AoD，PAS of AoD)、发射信道相关性(transmit channel correlation)、接收信道相关性(receive channel correlation)、发射波束成形(transmit beamforming)、接收波束成形(receive beamforming)、空间信道相关性(spatial channel correlation)等。
本实施例中，设置指定QCL类型为类型D，其有益效果包括：根据RS集合中QCL类型为QCL type D的RS索引确定BFD RS资源时，还可以确定出BFD RS资源的空间接收参数，UE根据该空间接收参数调整接收波束，使接收波束对准gNB发射BFD RS资源的发射方向，从而可以准确地测量BFD RS资源的质量，并根据测量结果判断是否发生波束失败事件。
一个实施例中，CORESET的TCI状态包括：当前小区当前BWP的CORESET的TCI状态。
具体地，网络侧设备通过RRC信令为UE所在的当前小区当前BWP的每个CORESET配置和指示CORESET的TCI状态，CORESET的TCI状态指示用于监听CORESET上的PDCCH的QCL参数，CORESET上传输的每个PDCCH的TCI状态均相同。
以上表1表2为例，UE监听PDCCH时采用与CSI-RS资源索引1(CSI-RS resource index 1)相对应的QCL type A的参数，包括多普勒频移，多普勒扩展、平均时延、时延扩展(Doppler shift,Doppler spread,average delay,delay spread)等，以及采用与CSI-RS resource index 2相对应的QCL type D的参数，包括空间接收参数(Spatial Rx parameter)。当UE确定BFD RS资源索引为CSI-RS resource index 2时，则UE根据该BFD RS资源索引确定BFD RS资源，检测该BFD RS资源所在波束的质量。
本实施例中，设置CORESET的TCI状态包括当前小区当前BWP的CORESET的TCI状态，可以使得UE根据所述TCI状态确定当前小区当前BWP的BFD RS资源，从而根据对BFD RS资源的测量结果判断当前小区当 前BWP上是否发生波束失败事件，所述当前BWP即为当前激活BWP(active BWP)。
本实施例中，BFD RS包括：周期CSI-RS、SSB中的至少一项。
图2为本公开一实施例提供的波束失败恢复方法的流程示意图，该方法可以应用于用户侧设备，由用户侧设备执行，如图2所示，该方法包括：
步骤202，判断是否被配置BFD RS资源；
若是，执行步骤206，否则，执行步骤204。
步骤204，根据CORESET的TCI状态，确定BFD RS资源及其QCL参数。
该步骤同图1中的方法，具体不在重复。
步骤206，根据BFD RS资源及其QCL参数，检测在当前小区当前BWP上是否发生波束失败事件。
具体地，UE在物理层根据BFD RS资源及其QCL参数，对BFD RS进行测量，并根据测量结果来判断是否发生波束失败事件。若发生，执行步骤208，否则，结束流程。
步骤208，查找候选波束。
具体地，UE在物理层测量候选波束参考信号(candidate beam RS)，寻找新的候选波束。当UE物理层收到来自UE高层的请求或指示或通知时，将满足预设条件的测量结果上报给UE高层，UE高层基于物理层的上报，来选择候选波束。其中，UE高层可以为MAC层，满足预设条件包括：对候选波束参考信号的测量质量超过预设门限，上报内容包括候选波束参考信号索引及其质量(如RSRP)。
步骤210，根据查找到的候选波束向网络侧设备发送波束失败恢复请求，以进行波束失败恢复。
UE高层根据所选的候选波束来确定PRACH资源(PRACH resource)。如果UE判断满足波束失败恢复请求的触发条件，则UE在所确定的PRACH资源上向网络侧设备发送波束失败恢复请求。UE需要根据网络侧设备配置的请求发送次数和/或请求发送时间来发送波束失败恢复请求，以进行波束失败恢复。
通过图2中的方法，当网络侧设备没有为UE配置BFD RS资源时，UE可以根据CORESET的TCI状态，确定BFD RS资源及其QCL参数，使得UE在网络侧设备没有配置BFD RS资源时，仍然可以执行波束失败检测与恢复机制，不会因无法进行波束失败检测和波束失败恢复而需要执行无线链路失败与重建过程，减少恢复数据传输所需的时延，提升通信系统的数据传输性能。
