波束失败恢复请求的发送、接收方法、终端及基站

本申请主张在2019年9月30日在中国提交的中国专利申请号No.201910945686.4的优先权，其全部内容通过引用包含于此。
技术领域
本公开涉及通信技术领域，尤其涉及一种波束失败恢复请求的发送、接收方法、终端及基站。
背景技术
对于无线通信系统，采用模拟波束赋形进行下行信号的传输可以实现更高赋形增益和更大覆盖。对于高频段系统的模拟波束赋形面临的一个重要挑战是传输信号的传播损耗大、被遮挡概率高。当物理下行控制信道(Physical Downlink Control Channel，PDCCH)信号被遮挡时，终端将无法准确获得下行传输的控制信息，从而接收性能下降，如速率下降、调度时延增加、用户体验下降等。
在长期演进(Long Term Evolution，LTE)等通信系统中，当为PDCCH配置的下行波束都失败时，就认为无线链路失败，开启无线链路重建的过程。这种方式除了增加时延外，还有可能会造成资源的浪费，因为换个发送波束和/或接收波束就有可能使得下行控制信号的接收质量可以满足要求。为了避免这种资源浪费和时延，目前有主小区(Primary cell，PCell)的波束失败恢复过程，以及辅小区(Secondary Cell，SCell)的波束失败恢复过程。
如果基站在一个或多个小区(可以为PCll或SCell)为终端(UE)配置了配置准许的物理上行共享信道(Physical Uplink Shared Channel，PUSCH)(即基于configured grant的PUSCH)，终端将用于携带波束失败恢复(beam failure recovery,BFR)信息的媒体接入控制层控制单元MAC-CE(Medium Access Control-Control Element)发送在这个已经分配的PUSCH资源上。由于基站在为终端配置配置准许的PUSCH时，无法预测发生波束失败的SCell， 因此，可能存在这样的情况：基站在为终端配置了配置准许的PUSCH，而这个已经分配的PUSCH资源对应的SCell发生了波束失败，导致UE在这个发生波束失败的SCell上发送携带BFR信息的MAC-CE时，可能由于上行波束性能差，导致UE发送的携带BFR信息的MAC-CE有可能无法被基站正确接收。而目前针对这种SCell发生波束失败的情况，终端在哪个小区发送波束失败恢复的请求信息还没有具体方案。

第一实施例
如图1所示，本公开的实施例提供了一种波束失败恢复请求的发送方法，应用于终端，包括：
步骤11：在检测到波束失败事件的情况下，按照预设优先级规则确定至少一个第一目标小区。
具体的，一个终端在进行了初始接入后可以被配置一个或多个SCell，一个SCell可以被配置为只有下行链路(downlink，DL)，或者包含下行链路DL和上行链路UL(Uplink)，每个SCell都可以进行BFR过程。上行波束和下行波束的质量通常是相关联的。上行波束管理(UL beam management)可以具有波束对应性(beam correspondence)或者不具有波束对应性(beam correspondence)。如果UE的上行和下行不具备波束对应性，UE独立于下行接收波束选择上行发送波束。如果UE的上行和下行具备波束对应性，UE可以根据下行接收波束确定上行发送波束，上行发送波束与下行接收波束使用 相同的空间滤波(spatial filter)。
BFR的目的是测量下行控制信道PDCCH的下行波束质量，或者认为测量控制资源集合(Control Resource SET，CORESET)的信道质量。UE通过检测用来进行SCell波束失败检测(Beam failure detection，BFD)的下行参考信号的质量来进行SCell的波束失败检测。用来进行SCell BFD的下行参考信号可以通过无线资源控制(Radio Resource Control，RRC)显式配置或者通过传输配置指示(Transmission Configuration Indicator，TCI)状态隐式配置。每个SCell最多可以配置8个下行波束(例如：最多8个TCI状态或者最多8个用于BFD的下行参考信号)。下行控制信道的波束是激活TCI状态的一个子集。
UE在检测到波束失败事件的情况下，向基站发送波束失败事件的上报信息。可选的，该上报信息可以通过专门配置给BFR的PUCCH资源发送，如通过发送类似于调度请求(schedule request，SR)的PUCCH的方式发送；当然，还可以通过专门配置给BFR的PUCCH资源之外的方式，来上报波束失败事件，本公开不以此为限。
可选地，在检测到波束失败事件的情况下，按照预设优先级规则确定一个第一目标小区。
步骤12：在所述至少第一目标小区上发送波束失败恢复的请求信息。
可选的，所述波束失败恢复的请求信息包括：发生波束失败的小区标识的指示信息和至少部分发生波束失败的小区对应的新波束的指示信息中的至少一项。
上述方案中，在检测到波束失败事件的情况下，按照预设优先级规则确定至少一个第一目标小区，实现通过至少一个第一目标小区发送波束失败恢复的请求信息的。解决了相关技术中在小区发生波束失败的情况，终端以何种小区发送波束失败恢复的请求信息还没有具体方案的问题。
可选的，上述步骤11可以具体包括：按照预设优先级规则，从第一小区集合中确定至少一个第一目标小区。
其中，作为一种实现方式，所述第一小区集合为基站为终端分配了上行共享信道PUSCH资源的所有小区所组成的集合的全集或子集，也即可以是 由基站为终端分配了PUSCH资源的所有小区组成该第一小区集合，或者是由基站为终端分配了PUSCH资源的所有小区中的一部分小区组成该第一小区集合。
由基站为终端分配了PUSCH资源的小区可以是由基站为终端分配了可用的PUSCH资源的小区，如：由基站根据终端发送的用于上报BFR请求的PUCCH为终端分配的PUSCH资源所在的小区以及其他已经存在了PUSCH资源的小区；或者，由基站为终端分配了PUSCH资源的小区可以是除基站根据专门配置给BFR的SR-like的PUCCH分配的PUSCH资源所在的小区之外的，其他已经存在了PUSCH资源分配的小区。
其中，可用的PUSCH资源的小区可以是基站通过下行控制信息(Downlink Control Information，DCI)调度的PUSCH资源、激活的配置准许类型2(configured grant Type 2)的PUSCH资源和配置准许类型1(configured grant Type 1)的PUSCH资源。或者，可用的PUSCH资源为基站分配的PUSCH资源。
作为另一种实现方式，所述第一小区集合为基站为终端配置了配置准许的PUSCH资源的所有小区所组成的集合的全集或子集。也即可以是由基站为终端配置了配置准许的PUSCH资源的所有小区组成该第一小区集合，或者是由基站为终端配置了配置准许的PUSCH资源的所有小区中的一部分小区组成该第一小区集合。
可选的，基站为终端配置了配置准许的PUSCH资源的小区可以是基站为终端配置了可用的配置准许的PUSCH资源的小区。其中，可用的配置准许的PUSCH资源可以是激活的configured grant Type 2的PUSCH资源和configured grant Type 1的PUSCH资源。或者，可用的配置准许的PUSCH资源可以是configured grant Type 1的PUSCH资源。
进一步地，所述第一小区集合中的所有小区均可以是发生了波束失败事件的小区所在的小区组内的小区。
可选的，第一小区集合为发生了波束失败事件的SCell所在的小区组，例如，主小区组(Master cell group，MCG)或辅小区组(Secondary cell group，SCG)里所有分配了PUSCH资源的小区所组成的集合。
可选地，第一小区集合为发生了波束失败事件的SCell所在的小区组，例如，MCG或SCG里不包含基站根据专门配置给BFR的SR-like的PUCCH分配的PUSCH资源所在的小区，为所有其他已经存在了PUSCH资源分配的小区。
可选地，第一小区集合为发生了波束失败事件的SCell所在的小区组，例如，MCG或SCG里所有配置了配置准许(configured grant)的PUSCH资源的小区。
可选的，作为一种实现方式，上述步骤11可以具体包括：
根据一个优先级条件，确定至少一个第一目标小区。
具体的，根据一个优先级条件确定至少一个第一目标小区，可以是存在一个优先级条件的情况下，根据该一个优先级条件，确定至少一个第一目标小区；也可以是存在多个优先级条件的情况下，根据这多个优先级条件中优先级等级最高的优先级条件确定至少一个第一目标小区。
其中，当根据该一个优先级条件，确定的至少一个小区的数量满足第一预设条件(如第一小区的数量不低于所需小区的数量)时，可以从该至少一个小区中确定所需数量的小区，作为第一目标小区，具体确定方式可以由UE实现，本公开不作具体限定；特别的，当该至少一个小区的数量与所需小区的数量先相同时，直接确定该至少一个小区全部为第一目标小区。
例如：优先级条件可以为未检测到波束失败事件的小区的优先级，高于检测到波束失败事件的小区的优先级；根据该优先级条件确定了2个小区：小区1、小区2；当所需小区的数量为1时，则可以从这2个小区中选择其中1个作为第一目标小区，如：选择小区1作为第一目标小区，或者选择小区2作为第一目标小区；当所需小区的数量为2时，则确定小区1和小区2为第一目标小区。
需要说明的是，该优先级条件还可以是除此之外的其他优先级条件，本公开实施例应不以此为限。
作为另一种实现方式，上述步骤12可以具体包括：根据N个优先级条件以及所述优先级条件的优先级等级，确定至少一个第一目标小区，其中N为大于1的正整数。
可选的，根据N个优先级条件以及所述优先级条件的优先级等级，确定至少一个第一目标小区，可以是根据N个优先级条件中的最高优先级等级的优先级条件，确定优先级最高的至少一个小区作为第一目标小区。
可选的，根据N个优先级条件以及所述优先级条件的优先级等级，确定至少一个第一目标小区，还可以通过以下步骤实现：
步骤一：按照所述N个优先级条件中第1优先级等级对应的优先级条件，确定第1优先级等级对应的小区数量K 1；
在K 1＝M时，确定所述第一目标小区为第1优先级等级对应的所有小区；
在K 1<M时，确定所述第一目标小区包括第1优先级等级对应的所有小区，令m＝2，X m＝M-K 1,进行步骤二；
在K 1>M时，令m＝2,X m＝M,进行步骤；
其中，所述步骤二为：
按照所述N个优先级条件中第m优先级等级对应的优先级条件，确定第m优先级等级对应的小区数量K m；
在K m＝X m时，确定所述第一目标小区包括第m优先级等级对应的所有小区；
在m＝N时且K m>X m时，从第m优先级等级对应的小区中确定所述第一目标小区；在m＝N且在K m<X m时，确定第一目标小区包括第m优先级对应的所有小区，再在优先级第m-1高的小区内再选择X m-K m个小区作为第一目标小区
在m<N且K m>X m时，令m＝m+1,重复步骤二；
在m<N且K m<X m时，进行步骤三；
其中，所述步骤三为：
确定第一目标小区包括第m优先级等级对应的所有小区，令m＝m+1，令X m＝X m-K m，重复步骤二。
例如：上述N个优先级条件为3个，等级由高到低依次为：第一优先级条件，第二优先级条件和第三优先级条件；M为1，则上述方法可以具体实现为：
根据第一优先级条件，确定得到第一目标小区集合(例如可以从第一小 区集合中按照第一优先级条件确定第一目标小区集合)；
作为第一种情况：在得到第一目标小区集合的情况下，若第一目标小区集合中的小区数量为3，则根据第二优先级条件从该第一目标小区结合中确定第二目标小区集合；
在得到第二目标小区集合的情况下，包含三种情况：作为一种子情况：若第二目标小区集合中小区的数量为1，则确定这个小区为第一目标小区，且流程结束(即不按照第三优先级等级的优先级条件进行选择)；作为另一种子情况：若第二目标小区集合中小区的数量为0，则按照第三优先级条件从第一目标小区中确定第三目标小区集合；作为再一种子情况，若第二目标小区集合中的小区数量为2，则按照第三优先级条件从第二目标小区结合中确定第三目标小区集合；
在得到第三目标集合的情况下，还包含三种情况：作为一种子情况：若第三目标小区集合中小区的数量为1，则确定这个小区为第一目标小区；作为另一种子情况：若第三目标小区集合中小区的数量为0，则从第一目标小区集合或第二目标小区集合(若第二目标小区集合存在的情况下)中选择一个小区作为第一目标小区；作为再一种子情况，若第三目标小区集合中的小区数量为2，则从这两个小区中选择一个作为第一目标小区(其中，具体选择方式可以由终端实现，这里不作具体限定)；
作为第二种情况：在得到第一目标小区集合的情况下，若第一目标小区集合中的小区数量为1，则确定这一个小区为第一目标小区，且流程结束(即不按照第二优先级条件和第三优先级条件进行选择)；
作为第三种情况：在得到第一目标小区集合的情况下，若第一目标小区集合中小区的数量为0，则直接根据第二优先级条件确定第二目标小区集合(例如可以从第一小区集合中按照第二优先级条件确定第二目标小区集合)；进而在得到第二目标小区集合后如何得到第一目标小区的方式可参见第一种情况中的方式，这里不再赘述。
再例如：上述N个优先级条件为2个，等级由高到低依次为：第一优先级条件，第二优先级条件；M为1，则上述方法可以具体实现为：
根据第一优先级条件，确定得到第一目标小区集合(例如可以从第一小 区集合中按照第一优先级条件确定第一目标小区集合)；
作为第一种情况：在得到第一目标小区集合的情况下，若第一目标小区集合中的小区数量为3，则根据第二优先级条件从该第一目标小区结合中确定第二目标小区集合；
在得到第二目标小区集合的情况下，作为一种子情况：若第二目标小区集合中的小区数量为2(当然也可以能是3)，则从这两个小区中选择一个作为第一目标小区(其中，具体选择方式可以由终端实现，这里不作具体限定)；作为另一种子情况：若第二目标小区集合中小区的数量为1，则确定这一个小区为第一目标小区；作为再一种子情况：若第二目标小区集合中小区的数量为0，则从第一目标小区集合中选择一个小区作为第一目标小区；
作为第二种情况：在得到第一目标小区集合的情况下，若第一目标小区集合中的小区数量为1，则确定这一个小区为第一目标小区；
作为第三种情况：在得到第一目标小区集合的情况下，若第一目标小区集合中小区的数量为0，则可以直接确定这一个小区作为第一目标小区，或者，直接根据第二优先级条件确定第二目标小区集合(例如可以从第一小区集合中按照第二优先级条件确定第二目标小区集合)；进而在得到第二目标小区集合后如何得到第一目标小区的方式可参见第一种情况中的方式，这里不再赘述。
可选的，根据N个优先级条件以及所述优先级条件的优先级等级，确定至少一个第一目标小区，还可以通过以下步骤实现：
步骤一：按照所述N个优先级条件中第i＝1优先级等级对应的优先级条件，确定优先级最高的小区组成的集合为第i个目标小区集合；
在第i个目标小区集合中的小区数量满足第一预设条件的情况下，确定所述第i个目标小区集合中的至少一个小区为所述第一目标小区；
在第i个目标小区集合中的小区数量不满足第一预设条件且不满足第二预设条件的情况下，执行以下步骤二；
在第i个目标小区集合中的小区数量不满足第一预设条件且满足第二预设条件的情况下，按照所述N个优先级条件中第i+1优先级等级对应的优先级条件，确定优先级最高的小区组成的集合为第i个目标小区集合，并重复 执行上述判断第i个目标小区集合的步骤；
步骤二：按照所述N个优先级条件中第i+1优先级等级对应的优先级条件，从第i个目标小区集合中确定至少一个小区作为第i+1个目标小区集合；其中，i为正整数，i小于N；
在i+1小于N时，在第i+1个目标小区集合中的小区数量满足所述第一预设条件的情况下，确定所述第i+1个目标小区集合中的至少一个小区为所述第一目标小区；在第i+1个目标小区集合中的小区数量满足第二预设条件的情况下，确定所述第i+1个目标小区集合和第i个目标小区集合中的至少一个小区为所述第一目标小区；在第i+1个目标小区集合中的小区数量不满足所述第一预设条件和所述第二预设条件的情况下，使得i＝i+1，重复执行所述步骤二；
在i+1等于N的情况下，在第i+1个目标小区集合中的小区数量满足所述第一预设条件的情况下，确定所述第i+1个目标小区集合中的至少一个小区为所述第一目标小区；在第i+1个目标小区集合中的小区数量满足第二预设条件的情况下，确定所述第i+1个目标小区集合和第i个目标小区集合中的至少一个小区为所述第一目标小区。
其中，第一预设条件可以是小区集合中的小区数量等于所述至少一个第一目标小区的数量，第二预设条件可以是小区集合中的小区数量低于所需小区的数量。
例如：上述N个优先级条件为3个，等级由高到低依次为：第一优先级条件，第二优先级条件和第三优先级条件；M为1，则上述方法可以具体实现为：
根据第一优先级条件，确定得到第一目标小区集合(例如可以从第一小区集合中按照第一优先级条件确定第一目标小区集合)；
作为第一种情况：在得到第一目标小区集合的情况下，若第一目标小区集合中的小区数量为3，则根据第二优先级条件从该第一目标小区结合中确定第二目标小区集合；
在得到第二目标小区集合的情况下，包含三种情况：作为一种子情况：若第二目标小区集合中小区的数量为1，则确定这个小区为第一目标小区，且 流程结束(即不按照第三优先级等级的优先级条件进行选择)；作为另一种子情况：若第二目标小区集合中小区的数量为0，则从第一目标小区集合中选择一个小区作为第一目标小区；作为再一种子情况，若第二目标小区集合中的小区数量为2，则按照第三优先级条件从第二目标小区结合中确定第三目标小区集合；
在得到第三目标集合的情况下，还包含三种情况：作为一种子情况：若第三目标小区集合中小区的数量为1，则确定这个小区为第一目标小区；作为另一种子情况：若第三目标小区集合中小区的数量为0，则从第一目标小区集合中选择一个小区作为第一目标小区；作为再一种子情况，若第二目标小区集合中的小区数量为2，则从这两个小区中选择一个作为第一目标小区(其中，具体选择方式可以由终端实现，这里不作具体限定)；
作为第二种情况：在得到第一目标小区集合的情况下，若第一目标小区集合中的小区数量为1，则确定这一个小区为第一目标小区，且流程结束(即不按照第二优先级条件和第三优先级条件进行选择)；
作为第三种情况：在得到第一目标小区集合的情况下，若第一目标小区集合中小区的数量为0，则可以直接从待选的小区中(如第一小区集合)确定一个小区作为第一目标小区，或者，直接根据第二优先级条件确定第二目标小区集合(例如可以从第一小区集合中按照第二优先级条件确定第二目标小区集合)；进而在得到第二目标小区集合后如何得到第一目标小区的方式可参见第一种情况中的方式，这里不再赘述。
再例如：上述N个优先级条件为2个，等级由高到低依次为：第一优先级条件，第二优先级条件；M为1，则上述方法可以具体实现为：
根据第一优先级条件，确定得到第一目标小区集合(例如可以从第一小区集合中按照第一优先级条件确定第一目标小区集合)；
作为第一种情况：在得到第一目标小区集合的情况下，若第一目标小区集合中的小区数量为3，则根据第二优先级条件从该第一目标小区结合中确定第二目标小区集合；
在得到第二目标小区集合的情况下，作为一种子情况：若第二目标小区集合中的小区数量为2(当然也可以能是3)，则从这两个小区中选择一个作 为第一目标小区(其中，具体选择方式可以由终端实现，这里不作具体限定)；作为另一种子情况：若第二目标小区集合中小区的数量为1，则确定这个一个小区为第一目标小区；作为再一种子情况：若第二目标小区集合中小区的数量为0，则从第一目标小区集合中选择一个小区作为第一目标小区；
作为第二种情况：在得到第一目标小区集合的情况下，若第一目标小区集合中的小区数量为1，则确定这一个小区为第一目标小区；

示例一：第一优先级等级的优先级条件为：未检测到波束失败事件的小区的优先级，高于检测到波束失败事件的小区的优先级；
第二优先级等级的优先级条件为：主小区的优先级高于辅小区的优先级；
其中，第一优先级等级高于第二优先级等级；
场景一：候选的小区包括：PCell和一个SCell，且该PCell和一个SCell均未检测到波束失败事件；
根据第一优先级等级的优先级条件，确定的至少一个小区包括：PCell和一个SCell，则确定该PCell和一个SCell所组成的小区集合为第1个目标小区集合；
若所需小区的数量为2，即第1个目标小区集合中的小区数量满足第一预设条件，则确定该PCell和一个SCell为第一目标小区；
若所需小区的数量为1，即第1个目标小区集合中的小区数量不满足第一预设条件，则根据第二优先级等级的优先级条件，从第1个目标小区集合中确定1个小区为：PCell；则确定该PCell为第一目标小区。
场景二：候选的小区包括：PCell和一个SCell，且该PCell检测到了波束失败事件，该SCell未检测到波束失败事件；
根据第一优先级等级的优先级条件，确定的至少一个小区包括：该SCell， 则确定该SCell所组成的小区集合为第1个目标小区集合；
若所需小区的数量为1，即第1个目标小区集合中的小区数量满足第一预设条件，则确定该SCell为第一目标小区。
若所需小区的数量为2，则可以根据该第二优先级等级的优先级条件从候选的所有小区中确定一个小区，与该SCell共同作为第一目标小区。
场景三：候选的小区包括：PCell和一个SCell，且该PCell均检测到了波束失败事件；
根据第一优先级等级的优先级条件，确定的小区数量为0；则可以将该PCell和一个SCell组成的小区集合作为第1个目标小区集合；
根据第一优先级等级的优先级条件，从第1个目标小区集合中确定的至少一个小区为PCell；
若所需小区的数量为1，则确定该PCell为第一目标小区。
示例二：第一优先级等级的优先级条件为：第一频段小区的优先级高于第二频段小区的优先级；
第二优先级等级的优先级条件为：未检测到波束失败事件的小区的优先级，高于检测到波束失败事件的小区的优先级；
第三优先级等级的优先级条件为：小区序号较低的小区优先级高于小区序号较高的小区优先级；
场景一：候选的小区有：小区1、小区2、小区3和小区4，其中，小区1、小区3的频段为频段1(Frequency Range 1，5G NR系统中的FR 1)，小区2和小区4的频段为频段2(Frequency Range 2，5G NR系统中的FR 2)；小区1、小区2、小区4均未检测到波束失败事件，小区3检测到了波束失败事件；所需小区数量为1；
根据第一优先级等级的优先级条件，确定的至少一个小区为：小区1、小区3；则将小区1、小区3所组成的集合作为第1个目标小区集合；
根据第二优先级等级的优先级条件，从第1个目标小区集合中确定的至少一个小区为：小区1，则将该小区1作为第一目标小区。
场景二：候选的小区有：小区1、小区2、小区3和小区4，其中，小区1、小区3的频段为频段1(Frequency Range 1，FR 1)，小区2和小区4的频 段为频段2(Frequency Range 2，FR 2)；小区1、小区2、小区4均未检测到波束失败事件，小区3检测到了波束失败事件；所需小区数量为2；
根据第一优先级等级的优先级条件，确定的至少一个小区为：小区1、小区3；则将小区1、小区3所组成的集合作为第1个目标小区集合；
根据第二优先级等级的优先级条件，从第1个目标小区集合中确定的至少一个小区为：小区1，则根据该小区1和第1个目标小区集合确定第2个目标小区集合为：小区1、小区3；
根据第三优先级等级的优先级条件，从第2个目标小区集合中选择两个小区即为小区1和小区3。
可选的，上述虽然给出了几种优先级条件的示例，但是应该理解的是，上述示例为说明确定第一目标小区的方法之用，即除上述优先级条件及优先级等级的设定外，还可以设定优先级条件：主小区的优先级高于辅小区的优先级，总是具有最高的优先级等级，即当PCell上分配了PUSCH资源时，UE总是在PCell上发送BFR信息，本公开实施例不以此为限。
可选的，所述优先级条件包括以下至少一项：
未进行波束失败检测的小区的优先级，高于已进行波束失败检测的小区的优先级；
未检测到波束失败事件的小区的优先级，高于检测到波束失败事件的小区的优先级；
主小区的优先级高于辅小区的优先级(如：可以是主小区的优先级高于主辅小区的优先级，主辅小区的优先级高于辅小区的优先级；或者还可以是主小区和主辅小区的优先级相同，主辅小区的优先级高于辅小区的优先级)；
小区序号较低的小区优先级高于小区序号较高的小区优先级；
第一频段小区的优先级高于第二频段小区的优先级；
载波频率较低的小区优先级高于载波频率较高的小区优先级；
第一小区的优先级高于第一目标小区集合中所述第一小区之外的小区优先级；其中，所述第一小区为基站根据终端所传输的专门配置给BFR的PUCCH所分配的PUSCH资源所在的小区；所述第一目标小区集合为基站分配了PUSCH资源的所有小区所构成的集合，或者所述目标小区集合为按照 具有更高优先级的优先级条件确定的至少一个小区所构成的集合；(具有更高优先级的优先级条件可以是指：在包括优先级条件为第一小区的优先级高于第一目标小区集合中所述第一小区之外的小区优先级的多个优先级条件中，比优先级条件为第一小区的优先级高于第一目标小区集合中所述第一小区之外的小区优先级的优先级等级高的其他优先级条件)；
第二小区的优先级高于第二目标小区集合中除所述第二小区之外的小区优先级；其中，所述第二小区为基站在接收到终端发送的波束失败事件上报后分配的PUSCH资源所在的小区；所述第二目标小区集合为基站分配了PUSCH资源的所有小区所构成的集合，或者所述第二目标小区集合为按照具有更高优先级的优先级条件确定的至少一个小区所构成的集合；(具有更高优先级的优先级条件可以是指：在包括优先级条件为第二小区的优先级高于第二目标小区集合中除所述第二小区之外的小区优先级的多个优先级条件中，比优先级条件为第二小区的优先级高于第二目标小区集合中除所述第二小区之外的小区优先级的优先级等级高的其他优先级条件)。
可选的，上述优先级条件联合使用，即采用多个优先级条件确定至少一个目标小区的情况下，这多个优先级条件中可以不包括：优先级条件为未进行波束失败检测的小区的优先级，高于已进行波束失败检测的小区的优先级，和优先级条件为未检测到波束失败事件的小区的优先级，高于检测到波束失败事件的小区的优先级；或者是这多个优先级条件中包括优先级条件为未进行波束失败检测的小区的优先级，高于已进行波束失败检测的小区的优先级；或者是这多个优先级条件中包括优先级条件为未检测到波束失败事件的小区的优先级，高于检测到波束失败事件的小区的优先级。
可选的，上述优先级条件联合使用，即采用多个优先级条件确定至少一个目标小区的情况下，这多个优先级条件中可以不包括：优先级条件为主小区的优先级高于主辅小区的优先级，主辅小区的优先级高于辅小区的优先级，和优先级条件为主小区和主辅小区的优先级相同，主辅小区的优先级高于辅小区的优先级；或者，这多个优先级条件可以包括：优先级条件为主小区的优先级高于主辅小区的优先级，主辅小区的优先级高于辅小区的优先级；或者，这多个优先级条件中可以包括：优先级条件为主小区和主辅小区的优先 级相同，主辅小区的优先级高于辅小区的优先级。
特别的，当采用了优先级条件为未检测到波束失败事件的小区的优先级，高于检测到波束失败事件的小区的优先级，确定至少一个第一目标小区时，可以避免UE在发生波束失败的小区上发送波束失败恢复请求，从而可以避免在波束失败的小区上发送波束失败恢复请求导致该波束失败恢复请求可能无法被基站接收的问题，从而有利于提高波束失败恢复请求传输的可靠性。
可选的，上述步骤12可以具体包括：在所述第一目标小区上发送发生波束失败的多个小区或发生波束失败的所有小区的波束失败恢复的请求信息。
可选的，UE可以将所有发生波束失败的小区的波束失败恢复的请求信息联合发送(如全部在第一目标小区上发送，或者在第一目标小区和其他小区上发送)。
可选的，UE可以针对每个发生波束失败的小区，分别发送波束失败恢复的请求信息。(例如：针对每个发生波束失败的小区，可以采用上述至少一个实施例的方法确定至少一个第一目标小区，并在该第一目标小区上发送波束失败恢复的请求信息)。
进一步地，在所述第一目标小区上发送发生波束失败的多个小区或发生波束失败的所有小区的波束失败恢复的请求信息，可以具体包括：
在基站为所述第一目标小区分配的可用的PUSCH资源，少于发送所述波束失败恢复的请求信息所需的资源的情况下，按照所述预设优先级规则确定除所述第一目标小区之外的至少一个第二目标小区；
在所述第一目标小区和所述第二目标小区上发送所述波束失败恢复的请求信息。
具体的，UE可以将多个发生了波束失败的波束失败恢复的请求信息联合在同一个小区上发送。
当基站为根据上述实施例的优先级规则确定的具有最高优先级的小区分配的PUSCH资源少于所述波束失败恢复的请求信息所需要的资源时，UE在可以承载所述波束失败恢复的请求信息的资源的小区中优先级最高的小区上发送波束失败恢复的请求信息。
当基站为根据上述实施例中的优先级规则确定的具有最高优先级的小区 分配的PUSCH资源少于所有发生了波束失败事件的小区的波束失败恢复的请求信息上报所需要的资源时，UE在优先级最高的小区上发送一部分波束失败恢复的请求信息，在优先级第二高的小区(可以是根据上述优先级规则从除优先级第一高的小区之外的第一小区集合中确定的至少一个小区)上发送余下的波束失败恢复的请求信息。这种方式可以扩展到更多的小区。例如优先级第二高的小区上不能完全发送余下的波束失败恢复的请求信息时，在优先级第三高的小区(可以是根据上述优先级规则从除优先级第一高和第二高的小区之外的第一小区集合中确定的至少一个小区)上发送在优先级第二高的部分上发送所剩余的一部分，以此类推，直至波束失败恢复的请求信息能够被完全发送。

以上从终端侧介绍了本公开实施例的波束失败恢复请求的发送方法，下面将结合附图对基站侧的波束失败恢复请求的接收方法做进一步说明。
如图4所示，本公开实施例提供了一种波束失败恢复请求的接收方法，应用于基站，包括：
步骤41：在第一目标小区上接收终端发送的波束失败恢复的请求信息。
其中，所述第一目标小区为：基站按照预设优先级规则确定的至少一个小区，或所述终端按照预设优先级规则确定的至少一个小区。
可选的，当第一目标小区为终端按照预设优先级规则确定的至少一个小区的情况下，基站可以在所有小区上接收波束失败恢复的请求信息。
可选的，终端与基站之间可以采用相同的优先级规则各自确定该第一目标小区，即终端在采用优先级规则确定的第一目标小区上发送波束失败恢复的请求信息，基站也可以采用相同的优先级规则确定的第一目标小区上接收波束失败恢复的请求信息，有利于提高接收效率。
所述第一目标小区为：基站按照预设优先级规则从第一小区集合中确定的至少一个小区，或所述终端按照预设优先级规则从第一小区集合中确定的至少一个小区；
其中，作为一种实现方式，所述第一小区集合为基站为终端分配了上行共享信道PUSCH资源的所有小区所组成的集合的全集或子集，也即可以是由基站为终端分配了PUSCH资源的所有小区组成该第一小区集合，或者是 由基站为终端分配了PUSCH资源的所有小区中的一部分小区组成该第一小区集合。
由基站为终端分配了PUSCH资源的小区可以是由基站为终端分配了可用的PUSCH资源的小区，如：由基站为终端分配了PUSCH资源的小区的PUCCH分配的PUSCH资源所在的小区以及其他已经存在了PUSCH资源的小区；或者，由基站为终端分配了PUSCH资源的小区可以是除基站根据专门配置给BFR的SR-like的PUCCH分配的PUSCH资源所在的小区之外的，其他已经存在了PUSCH资源分配的小区。
其中，可用的PUSCH资源的小区可以是基站通过DCI调度的PUSCH资源、激活的配置准许类型2(configured grant Type 2)的PUSCH资源和配置准许类型1(configured grant Type 1)的PUSCH资源。或者，可用的PUSCH资源为基站分配的PUSCH资源。
作为另一种实现方式，所述第一小区集合为基站为终端配置了配置准许的PUSCH资源的所有小区所组成的集合的全集或子集。也即可以是由基站为终端配置了配置准许的PUSCH资源的所有小区组成该第一小区集合，或者是由基站为终端配置了配置准许的PUSCH资源的所有小区中的一部分小区组成该第一小区集合。
可选的，基站为终端配置了配置准许的PUSCH资源的小区可以是基站为终端配置了可用的配置准许的PUSCH资源的小区。其中，可用的配置准许的PUSCH资源可以是激活的configured grant Type 2的PUSCH资源和configured grant Type 1的PUSCH资源。或者，可用的配置准许的PUSCH资源可以是configured grant Type 1的PUSCH资源。
其中，当所述第一目标小区为所述终端按照预设优先级规则从第一小区集合中确定的至少一个小区的情况下，所述第一小区集合中的所有小区均可以是发生了波束失败事件的小区所在的小区组内的小区。
可选的，第一小区集合为发生了波束失败事件的SCell所在的小区组，例如，主单元组(Master cell group，MCG)或辅单元组(Secondary cell group，SCG)里所有分配了PUSCH资源的小区所组成的集合。
可选地，第一小区集合为发生了波束失败事件的SCell所在的小区组，例 如，MCG或SCG里不包含基站根据专门配置给BFR的SR-like的PUCCH分配的PUSCH资源所在的小区，为所有其他已经存在了PUSCH资源分配的小区。
可选地，第一小区集合为发生了波束失败事件的SCell所在的小区组，例如，MCG或SCG里所有配置了配置准许(configured grant)的PUSCH资源的小区。
如图5，发明实施例还提供了一种波束失败恢复请求的接收方法，应用于基站，包括：
步骤51：接收终端发送的波束失败事件的上报信息。
该实施例中，终端检测到发生波束失败事件的情况下，向基站上报波束失败事件的上报信息。
步骤52：按照预设优先级规则，确定至少一个第一目标小区。
步骤53：在所述第一目标小区为所述终端分配PUSCH资源，所述PUSCH资源可用于所述终端传输波束失败恢复的请求信息。
该实施例中，终端可以在基站根据预设优先级规则确定的至少一个第一目标小区上所分配的PUSCH资源上发送波束失败恢复的请求信息。即确定第一目标小区可以由基站实现，解决了相关技术中在小区发生波束失败的情况，终端以何种小区发送波束失败恢复的请求信息还没有具体方案的问题。
根据以上至少一个基站测波束失败恢复请求的接收方法，可选的按照预设优先级规则，确定至少一个第一目标小区，包括：
根据一个优先级条件，确定至少一个第一目标小区；
或者，根据N个优先级条件以及所述优先级条件的优先级等级，确定至少一个第一目标小区，其中N为大于1的正整数。
该实施例的具体实现方式可参考终端侧的按照预设优先级规则，确定至少一个第一目标小区的具体实现方式，只是基站侧的优先级条件与终端侧的优先级条件略有不同，此处不再赘述。
可选的，根据N个优先级条件以及所述优先级条件的优先级等级，确定至少一个第一目标小区，还可以通过以下步骤实现：
步骤一：按照所述N个优先级条件中第1优先级等级对应的优先级条件， 确定第1优先级等级对应的小区数量K 1；
在K 1＝M时，确定所述第一目标小区为第1优先级等级对应的所有小区；
在K 1<M时，确定所述第一目标小区包括第1优先级等级对应的所有小区，令m＝2，X m＝M-K 1,进行步骤二；
在K 1>M时，令m＝2,X m＝M,进行步骤；
其中，所述步骤二为：
按照所述N个优先级条件中第m优先级等级对应的优先级条件，确定第m优先级等级对应的小区数量K m；
在K m＝X m时，确定所述第一目标小区包括第m优先级等级对应的所有小区；
在m＝N时且K m>X m时，从第m优先级等级对应的小区中确定所述第一目标小区；在m＝N且在K m<X m时，确定第一目标小区包括第m优先级对应的所有小区，再在优先级第m-1高的小区内再选择X m-K m个小区作为第一目标小区
在m<N且K m>X m时，令m＝m+1,重复步骤二；
在m<N且K m<X m时，进行步骤三；
其中，所述步骤三为：
确定第一目标小区包括第m优先级等级对应的所有小区，令m＝m+1，令X m＝X m-K m，重复步骤二。
例如：上述N个优先级条件为3个，等级由高到低依次为：第一优先级条件，第二优先级条件和第三优先级条件；M为1，则上述方法可以具体实现为：
根据第一优先级条件，确定得到第一目标小区集合(例如可以从第一小区集合中按照第一优先级条件确定第一目标小区集合)；
作为第一种情况：在得到第一目标小区集合的情况下，若第一目标小区集合中的小区数量为3，则根据第二优先级条件从该第一目标小区结合中确定第二目标小区集合；
在得到第二目标小区集合的情况下，包含三种情况：作为一种子情况：若第二目标小区集合中小区的数量为1，则确定这个小区为第一目标小区，且 流程结束(即不按照第三优先级等级的优先级条件进行选择)；作为另一种子情况：若第二目标小区集合中小区的数量为0，则按照第三优先级条件从第一目标小区中确定第三目标小区集合；作为再一种子情况，若第二目标小区集合中的小区数量为2，则按照第三优先级条件从第二目标小区结合中确定第三目标小区集合；
在得到第三目标集合的情况下，还包含三种情况：作为一种子情况：若第三目标小区集合中小区的数量为1，则确定这个小区为第一目标小区；作为另一种子情况：若第三目标小区集合中小区的数量为0，则从第一目标小区集合或第二目标小区集合(若第二目标小区集合存在的情况下)中选择一个小区作为第一目标小区；作为再一种子情况，若第三目标小区集合中的小区数量为2，则从这两个小区中选择一个作为第一目标小区(其中，具体选择方式可以由终端实现，这里不作具体限定)；
作为第二种情况：在得到第一目标小区集合的情况下，若第一目标小区集合中的小区数量为1，则确定这一个小区为第一目标小区，且流程结束(即不按照第二优先级条件和第三优先级条件进行选择)；
作为第三种情况：在得到第一目标小区集合的情况下，若第一目标小区集合中小区的数量为0，则直接根据第二优先级条件确定第二目标小区集合(例如可以从第一小区集合中按照第二优先级条件确定第二目标小区集合)；进而在得到第二目标小区集合后如何得到第一目标小区的方式可参见第一种情况中的方式，这里不再赘述。
再例如：上述N个优先级条件为2个，等级由高到低依次为：第一优先级条件，第二优先级条件；M为1，则上述方法可以具体实现为：
根据第一优先级条件，确定得到第一目标小区集合(例如可以从第一小区集合中按照第一优先级条件确定第一目标小区集合)；
作为第一种情况：在得到第一目标小区集合的情况下，若第一目标小区集合中的小区数量为3，则根据第二优先级条件从该第一目标小区结合中确定第二目标小区集合；
在得到第二目标小区集合的情况下，作为一种子情况：若第二目标小区集合中的小区数量为2(当然也可以能是3)，则从这两个小区中选择一个作 为第一目标小区(其中，具体选择方式可以由终端实现，这里不作具体限定)；作为另一种子情况：若第二目标小区集合中小区的数量为1，则确定这一个小区为第一目标小区；作为再一种子情况：若第二目标小区集合中小区的数量为0，则从第一目标小区集合中选择一个小区作为第一目标小区；
作为第二种情况：在得到第一目标小区集合的情况下，若第一目标小区集合中的小区数量为1，则确定这一个小区为第一目标小区；
作为第三种情况：在得到第一目标小区集合的情况下，若第一目标小区集合中小区的数量为0，则可以直接确定这一个小区作为第一目标小区，或者，直接根据第二优先级条件确定第二目标小区集合(例如可以从第一小区集合中按照第二优先级条件确定第二目标小区集合)；进而在得到第二目标小区集合后如何得到第一目标小区的方式可参见第一种情况中的方式，这里不再赘述。
可选的，所述根据N个优先级条件以及所述优先级条件的优先级等级，确定至少一个第一目标小区，包括：
步骤一：按照所述N个优先级条件中第i＝1优先级等级对应的优先级条件，确定优先级最高的小区组成的集合为第i个目标小区集合；
在第i个目标小区集合中的小区数量满足第一预设条件的情况下，确定所述第i个目标小区集合中的至少一个小区为所述第一目标小区；
在第i个目标小区集合中的小区数量不满足第一预设条件且不满足第二预设条件的情况下，执行以下步骤二；
在第i个目标小区集合中的小区数量不满足第一预设条件且满足第二预设条件的情况下，按照所述N个优先级条件中第i+1优先级等级对应的优先级条件，确定优先级最高的小区组成的集合为第i个目标小区集合，并重复执行上述判断第i个目标小区集合的步骤；
步骤二：按照所述N个优先级条件中第i+1优先级等级对应的优先级条件，从第i个目标小区集合中确定至少一个小区作为第i+1个目标小区集合；其中，i为正整数，i小于N；
在i+1小于N时，在第i+1个目标小区集合中的小区数量满足所述第一预设条件的情况下，确定所述第i+1个目标小区集合中的至少一个小区为所 述第一目标小区；在第i+1个目标小区集合中的小区数量满足第二预设条件的情况下，确定所述第i+1个目标小区集合和第i个目标小区集合中的至少一个小区为所述第一目标小区；在第i+1个目标小区集合中的小区数量不满足所述第一预设条件和所述第二预设条件的情况下，使得i＝i+1，重复执行所述步骤二；
在i+1等于N的情况下，在第i+1个目标小区集合中的小区数量满足所述第一预设条件的情况下，确定所述第i+1个目标小区集合中的至少一个小区为所述第一目标小区；在第i+1个目标小区集合中的小区数量满足第二预设条件的情况下，确定所述第i+1个目标小区集合和第i个目标小区集合中的至少一个小区为所述第一目标小区。
该实施例的具体实现方式可参考终端侧的按照预设优先级规则，确定至少一个第一目标小区的具体实现方式，只是基站侧的优先级条件与终端侧的优先级条件略有不同。
例如：上述N个优先级条件为3个，等级由高到低依次为：第一优先级条件，第二优先级条件和第三优先级条件；M为1，则上述方法可以具体实现为：
根据第一优先级条件，确定得到第一目标小区集合(例如可以从第一小区集合中按照第一优先级条件确定第一目标小区集合)；
作为第一种情况：在得到第一目标小区集合的情况下，若第一目标小区集合中的小区数量为3，则根据第二优先级条件从该第一目标小区结合中确定第二目标小区集合；
在得到第二目标小区集合的情况下，包含三种情况：作为一种子情况：若第二目标小区集合中小区的数量为1，则确定这个小区为第一目标小区，且流程结束(即不按照第三优先级等级的优先级条件进行选择)；作为另一种子情况：若第二目标小区集合中小区的数量为0，则从第一目标小区集合中选择一个小区作为第一目标小区；作为再一种子情况，若第二目标小区集合中的小区数量为2，则按照第三优先级条件从第二目标小区结合中确定第三目标小区集合；
在得到第三目标集合的情况下，还包含三种情况：作为一种子情况：若 第三目标小区集合中小区的数量为1，则确定这个小区为第一目标小区；作为另一种子情况：若第三目标小区集合中小区的数量为0，则从第一目标小区集合中选择一个小区作为第一目标小区；作为再一种子情况，若第二目标小区集合中的小区数量为2，则从这两个小区中选择一个作为第一目标小区(其中，具体选择方式可以由终端实现，这里不作具体限定)；
作为第二种情况：在得到第一目标小区集合的情况下，若第一目标小区集合中的小区数量为1，则确定这一个小区为第一目标小区，且流程结束(即不按照第二优先级条件和第三优先级条件进行选择)；
作为第三种情况：在得到第一目标小区集合的情况下，若第一目标小区集合中小区的数量为0，则可以直接从待选的小区中(如第一小区集合)确定一个小区作为第一目标小区，或者，直接根据第二优先级条件确定第二目标小区集合(例如可以从第一小区集合中按照第二优先级条件确定第二目标小区集合)；进而在得到第二目标小区集合后如何得到第一目标小区的方式可参见第一种情况中的方式，这里不再赘述。
再例如：上述N个优先级条件为2个，等级由高到低依次为：第一优先级条件，第二优先级条件；M为1，则上述方法可以具体实现为：
根据第一优先级条件，确定得到第一目标小区集合(例如可以从第一小区集合中按照第一优先级条件确定第一目标小区集合)；
作为第一种情况：在得到第一目标小区集合的情况下，若第一目标小区集合中的小区数量为3，则根据第二优先级条件从该第一目标小区结合中确定第二目标小区集合；
在得到第二目标小区集合的情况下，作为一种子情况：若第二目标小区集合中的小区数量为2(当然也可以能是3)，则从这两个小区中选择一个作为第一目标小区(其中，具体选择方式可以由终端实现，这里不作具体限定)；作为另一种子情况：若第二目标小区集合中小区的数量为1，则确定这个一个小区为第一目标小区；作为再一种子情况：若第二目标小区集合中小区的数量为0，则从第一目标小区集合中选择一个小区作为第一目标小区；

第二优先级等级的优先级条件为：主小区的优先级高于辅小区的优先级；
其中，第一优先级等级高于第二优先级等级；
场景一：候选的小区包括：PCell和一个SCell，且该PCell和一个SCell均未检测到波束失败事件；
根据第一优先级等级的优先级条件，确定的至少一个小区包括：PCell和一个SCell，则确定该PCell和一个SCell所组成的小区集合为第1个目标小区集合；
若所需小区的数量为2，即第1个目标小区集合中的小区数量满足第一预设条件，则确定该PCell和一个SCell为第一目标小区；

根据第一优先级等级的优先级条件，从第1个目标小区集合中确定的至少一个小区为PCell；
若所需小区的数量为1，则确定该PCell为第一目标小区。
示例二：第一优先级等级的优先级条件为：第一频段小区的优先级高于第二频段小区的优先级；
第二优先级等级的优先级条件为：终端未上报发生波束失败事件的小区的优先级，高于终端已上报发生波束失败事件的小区的优先级；
第三优先级等级的优先级条件为：小区序号较低的小区优先级高于小区序号较高的小区优先级；
场景一：候选的小区有：小区1、小区2、小区3和小区4，其中，小区1、小区3的频段为频段1(Frequency Range 1，5G NR系统中的FR 1)，小区2和小区4的频段为频段2(Frequency Range 2，5G NR系统中的FR 2)；针对小区1、小区2、小区4终端均未为上报检测到波束失败事件，针对小区3终端上报检测到了波束失败事件；所需小区数量为1；

可选的，上述虽然给出了几种优先级条件的示例，但是应该理解的是，上述示例为说明确定第一目标小区的方法之用，即除上述优先级条件及优先级等级的设定外，还可以设定优先级条件：主小区的优先级高于辅小区的优先级，总是具有最高的优先级等级，即当接收到终端的波束失败上百时，总是在PCell上分配PUSCH资源，以使UE总是在PCell上发送BFR信息，本公开实施例不以此为限。可选的，所述优先级条件包括以下至少一项：
终端未上报发生波束失败事件的小区的优先级，高于终端已上报发生波束失败事件的小区的优先级；

可选的，上述优先级条件联合使用，即采用多个优先级条件确定至少一个目标小区的情况下，这多个优先级条件中可以不包括：优先级条件为主小区的优先级高于主辅小区的优先级，主辅小区的优先级高于辅小区的优先级，和优先级条件为主小区和主辅小区的优先级相同，主辅小区的优先级高于辅小区的优先级；或者，这多个优先级条件可以包括：优先级条件为主小区的优先级高于主辅小区的优先级，主辅小区的优先级高于辅小区的优先级；或者，这多个优先级条件中可以包括：优先级条件为主小区和主辅小区的优先级相同，主辅小区的优先级高于辅小区的优先级。
特别的，当采用优先级条件为终端未上报发生波束失败事件的小区的优先级，高于终端已上报发生波束失败事件的小区的优先级，确定至少一个目标小区时，可以在一定程度上避免UE在发生波束失败的小区上发送波束失败恢复请求，从而可以避免终端在波束失败的小区上发送波束失败恢复请求 导致该波束失败恢复请求可能无法被基站接收的问题，从而有利于提高波束失败恢复请求传输的可靠性。

以下结合具体示例，对上述终端和基站的交互过程具体说明：
示例一：
终端(UE)监测波束失败事件，当UE监测到波束失败事件时，通过BFR专属的SR-like的PUCCH向基站(例如gNB)发送波束失败恢复事件上报。
基站接收到终端发送的波束失败事件上报，根据所述PUCCH为终端分配PUSCH资源。
终端根据第一优先级规则确定分配了PUSCH资源的小区的优先级，在优先级最高的小区上发送发生了波束失败事件的小区序号。
其中，第一优先级规则为：FR 1(如小于6GHz的频段)的小区(Cell) 相对于FR 2(如大于6GHz的频段)的Cell具有更高的优先级；在所有Cell都为相同频段的情况下，具有较低小区序号(index)的Cell的优先级高于具有较高小区序号的Cell的优先级。
如：一个小区组中包含SCell 1、SCell 2、SCell 3和SCell 4，其中SCell 1和SCell 3为FR 1的小区，SCell 2和SCell 4为FR 2的小区。当UE确定SCell 1和SCell 2发生了波束失败事件，UE向基站发送波束失败事件上报。基站为终端分配了承载波束失败事件上报的PUCCH所对应的PUSCH资源。
若基站将该PUSCH资源分配在了SCell 4上，在SCell 3上存在可用的配置准许的PUSCH资源。则UE根据第一优先级规则，确定SCell 3的优先级高于SCell 4的优先级，则在SCell 3上报SCell 1和SCell 2的BFR信息(如小区序号)。
其中，第一优先级规则为：基站根据基于终端传输的专门配置给BFR的SR-like的PUCCH所分配的PUSCH资源所在的小区相对于其他分配了PUSCH资源的小区具有更高的优先级，在同为基于终端传输的专门配置给BFR的SR-like的PUCCH所分配的PUSCH资源的情况下，具有较低小区序号(index)的Cell的优先级高于具有较高小区序号的Cell的优先级。
如：一个小区组中包含SCell 1、SCell 2、SCell 3和SCell 4，其中SCell 1和SCell 3为FR 1的小区，SCell 2和SCell 4为FR 2的小区。当UE确定SCell 1和SCell 2发生了波束失败事件，UE向基站发送波束失败事件上报。基站为终端分配了承载波束失败事件上报的PUCCH所对应的PUSCH资源。
若基站将该PUSCH资源分配在了SCell 3和SCell 4上。则UE根据第一优先级规则，确定小区序号更小的SCell 3的优先级高于SCell 4的优先级，则在SCell 3上报SCell 1和SCell 2的BFR信息(如小区序号)。
示例二：
UE监测波束失败事件，当UE监测到波束失败事件时，通过物理随机接入信道(Physical Random Access Channel，PRACH)信号向基站(如gNB)发送波束失败恢复事件上报。
终端根据第一优先级规则确定第一小区集合中小区的优先级，在优先级最高的小区上发送发生了波束失败事件的小区序号。
可选地，第一小区集合是所有配置了配置准许的PUSCH的小区组成的集合。
其中，第一优先级规则为：未检测到波束失败事件的小区相对于检测到了波束失败事件的小区具有更高的优先级。
如：一个小区组中包含SCell 1、SCell 2、SCell 3和SCell 4，其中SCell 1、SCell 3和SCell 4上都配置了可用的配置准许的PUSCH。当UE确定SCell 1和SCell 2发生了波束失败事件，UE向基站发送波束失败事件上报。则UE根据第一优先级规则，确定SCell 3和SCell 4的优先级高于SCell 1的优先级，则在SCell 3和SCell 4中选择一个SCell上报SCell 1和SCell 2的BFR信息(如小区序号)。
