请参见图2，图2是本公开实施例提供的一种发生波束失败的处理方法的流程图，该方法应用于终端，如图2所示，包括以下步骤：
步骤201、若在SCell发生波束失败，则触发发送BFRQ信息和BFRQ的调度请求SR中至少一项；
其中，所述终端针对所述SCell具备如下至少一项特征：
若满足第一条件，则禁止触发发送后续的BFRQ信息和BFRQ的SR中至少一项；
允许触发发送至少一次BFRQ的SR；
限制触发发送一次BFRQ信息；

其中，所述第三条件包括如下至少一项：
波束失败恢复成功；
禁止触发发送后续的BFRQ信息和BFRQ的SR中至少一项；
解除所述触发发送后续的BFRQ信息和BFRQ的SR中至少一项的禁止。
其中，上述若在SCell发生波束失败，则触发发送BFRQ信息和BFRQ的SR中至少一项可以是，若在SCell发生波束失败，触发BFRQ信息和/或触发BFRQ的SR，以及发送BFRQ信息和/或发送BFRQ的SR。例如：当终端检测到在SCell发生波束失败时，触发BFRQ信息和/或触发BFRQ的SR，以及发送BFRQ信息和/或发送BFRQ的SR。
另外，上述检测到在SCell发生波束失败可以是：终端物理层测量SCell的波束失败检测参考信号(beam failure detection reference signal，BFD RS)，并根据测量结果向媒体接入控制(Media Access Control，MAC)层上报BFI指示，MAC层启动或重启该SCell对应的波束失败检测定时器(beamFailureDetectionTimer)，并将BFI计数器(BFI_COUNTER)加1。当BFI_COUNTER大于或等于最大计数值(BFI_COUNTER>＝beamFailureInstanceMaxCount)时，则确定在SCell发生了波束失败事件。
需要说明的是，本公开实施例中，并不限定如何检测到(或者确定)发生波束失败，例如：可以采用类似于协议中已定义针对主小区(Primary Cell，PCell)波束失败的方式，也可以采用后续协议版本新引入的方式。
而上述SCell可以是主小区组(Master Cell Group，MCG)或者辅小区组(Secondary Cell Group，SCG)中的SCell。
上述BFRQ信息可以是用于请求波束失败恢复的相关信息，例如：所述BFRQ信息可以包括如下至少一项：
发生所述波束失败的SCell的索引信息和新波束的信息。
其中，上述新波束信息可以是终端选择的新波束的信息，例如：终端物理层可以测量发生波束失败的SCell的候选波束参考信号(candidate beam RS)，寻找质量满足预设要求的新的候选波束(candidate beam)，以得到上述新波 束。
需要说明的是，本公开实施例中，波束也可以称为空间滤波器(spatial filter)或者空域传输滤波器(spatial domain transmission filter)等。而波束信息也可以使用其它词表示，如：传输配置指示状态(transmission configuration indication state，TCI state)信息、准共址(Quasi-colocation，QCL)信息、空间关系(spatial relation)信息等。
另外，上述BFRQ信息可以在媒体接入控制控制单元(Media Access Control Control Element，MAC CE)中传输，当然，对此不作限定。另外，BFRQ信息也可以称作BFRQ或者BFRQ报告。
而上述BFRQ的SR可以是用于请求网络侧调度资源的SR。进一步地，上述BFRQ的SR可以采用协议中已定义的用于请求网络侧调度传输数据的上行资源的SR，或者采用协议中已定义的BFRQ的SR，例如：针对PCell的BFRQ的SR。或者上述SR可以为专用SR(dedicated SR)，且所述SR在网络配置的专用于BFR的物理上行控制信道(Physical Uplink Control Channel，PUCCH)资源上传输(dedicated SR-like PUCCH resource)。且上述BFRQ的SR可以在PCell、主辅小区(Primary Secondary Cell，PSCell)或SCell上传输。
需要说明的是，上述BFRQ信息和BFRQ的SR可以是在不同或者相同的小区、不同或者相同的资源，或者不同或者相同的时机传输。
需要说明的是，本公开实施例中，由于SCell发生波束失败，触发发送有BFRQ信息和BFRQ的SR中至少一项，这样就可以支持在SCell进行BFR，因为，发送了BFRQ信息和BFRQ的SR中至少一项之后，那么，终端可以在BFRQ信息和BFRQ的SR中至少一项的基础上完成BFR过程。需要说明的是，本公开实施例中，并不限定BFR过程，该过程可以是采用协议中已定义的，例如：针对PCell的BFR过程，或者可以是后续协议中新定义的关于SCell的BFR过程。
本公开实施例中，上述若满足第一条件，则禁止触发发送后续的BFRQ信息和BFRQ的SR中至少一项可以是，在满足上述第一条件的情况下，禁止触发后续的BFRQ和BFRQ的SR中至少一项，以及禁止发送后续的BFRQ 和BFRQ的SR中至少一项。另外，上述后续的BFRQ信息和BFRQ的SR可以是指步骤201触发的BFRQ信息和BFRQ的SR之后的BFRQ信息和BFRQ的SR。
可选地，所述第一条件包括如下至少一项：
触发所述BFRQ信息、发送所述BFRQ信息、所述BFRQ信息发送成功、第一定时器运行。
需要说明的是，上述触发所述BFRQ信息，可以是在步骤201触发BFRQ信息后，则禁止触发发送后续的BFRQ信息和BFRQ的SR中至少一项。也就是说，在该情况下，并不需要执行满足第一条件的判断，即触发了BFRQ信息，就表示满足了第一条件。从而上述若满足第一条件，则禁止触发发送后续的BFRQ信息和BFRQ的SR中至少一项可以是，若触发BFRQ信息，则禁止触发发送后续的BFRQ信息和BFRQ的SR中至少一项，如触发了传输BFRQ的MAC CE，则禁止触发发送后续的BFRQ信息和BFRQ的SR中至少一项。
同理，上述发送所述BFRQ信息，可以是在步骤201发送BFRQ信息后，则禁止触发发送后续的BFRQ信息和BFRQ的SR中至少一项。也就是说，在该情况下，并不需要执行满足第一条件的判断，即发送了BFRQ信息，就表示满足了第一条件。从而上述若满足第一条件，则禁止触发发送后续的BFRQ信息和BFRQ的SR中至少一项可以是，若发送BFRQ信息，则禁止触发发送后续的BFRQ信息和BFRQ的SR中至少一项，如发送了传输BFRQ的MAC CE，则禁止触发发送后续的BFRQ信息和BFRQ的SR中至少一项。

该实施方式中，可以及时解除所述触发发送后续的BFRQ信息和BFRQ的SR中至少一项的禁止，使得终端可以再次对SCell执行波束失败恢复过程，即在SCell再次发生波束失败时及时发送BFRQ信息和BFRQ的SR中至少一项，以及时进行恢复。
本公开实施例中，允许触发发送至少一次BFRQ的SR可以是，限定了终端触发发送SR的次数，这样可以避免终端发送过多的BFRQ的SR。
可选地，所述允许触发发送至少一次BFRQ的SR是指：完成BFR之前，MAC层允许触发发送至少一个等待的SR(pending SR)，且若完成所述BFR，则取消等待的SR。
其中，上述允许触发发送至少一个pending SR可以是，MAC层允许发送全部或者部分的pending SR。
该实施方式可以是，终端MAC层允许根据BFI_COUNTER大于或等于最大计数值来至少一次触发BFRQ的SR发送。其中，这里的至少一次可以是网络配置的、协议约定的或者终端预配置的。由于允许触发发送至少一个等待的SR(pending SR)，且若完成所述BFR，则取消等待的SR，这样可以避免终端发送过多等待的SR，以造成资源浪费。
本公开实施例中，限制触发发送一次BFRQ信息可以是，针对发生波束失败的SCell，终端只允许触发发送一次BFRQ信息，或者可以是，在对所述SCell的一个BFR过程中仅作一次触发发送BFRQ信息，从而避免因BFI_COUNTER不停计数导致的多次触发BFRQ信息，而影响到当前正在进行的SCell BFR过程。
可选地，所述限制触发发送一次BFRQ信息是指：完成BFR之前，限制 触发发送一次BFRQ信息。
例如：对于等待的用于发送BFRQ的MAC CE(pending MAC CE for BFRQ)，在SCell BFR完成之前，且在触发了MAC CE for BFRQ之后，终端的MAC层仅仅允许对所述发生波束失败的SCell只发送一个MAC CE for BFRQ。
该实施方式中，由于限制触发发送一次所述BFRQ信息，这样可以避免因BFI_COUNTER不停计数导致的多次触发BFRQ信息，而影响到当前正在进行的SCell BFR过程。
本公开实施例中，满足第二条件，则BFI计数器不计数可以是，在满足第二条件下，BFI计数器不计数，或者禁止BFI计数器计数，这样可以避免因BFI_COUNTER不停计数导致的多次触发BFRQ信息，而影响到当前正在进行的SCell BFR过程。

本公开实施例中，上述若满足第三条件，则重置BFI计数器可以是，若满足一定条件，则BFI计数器重置，从而可以减少BFI_COUNTER触发发生波束失败的资源，以避免发送过多的BFRQ信息和BFRQ的SR，影响到当前正在进行的SCell BFR过程，并且通过对BFI计数器重置，可以对该SCell进行再次的波束失败检测以及波束失败恢复。
可选地，上述若满足第三条件，则重置BFI计数器是指：在未满足所述第二条件的情况下，若满足所述第三条件，则重置所述BFI计数器；和/或
在满足所述第二条件，所述BFI计数器不计数的情况下，若满足所述第三条件，则解除所述BFI计数器不计数。
其中，上述解除所述BFI计数器不计数可以是解除计数器计数的禁止，或不禁止BFI计数器计数，从而后续满足计数器计数条件时，仍计数。
由于满足所述第三条件，则解除所述BFI计数器不计数，这样可以及时 地检测到再次发生的波束失败，及时发送BFRQ信息，以进行BFR。
本公开实施例中，若在SCell发生波束失败，则触发发送BFRQ信息和BFRQ的调度请求SR中至少一项；其中，所述终端针对所述SCell具备如下至少一项特征：若满足第一条件，则禁止触发发送后续的BFRQ信息和BFRQ的SR中至少一项；允许触发发送至少一次BFRQ的SR；限制触发发送一次BFRQ信息；若满足第二条件，则BFI计数器不计数；若满足第三条件，则重置BFI计数器；所述第三条件包括如下至少一项：波束失败恢复成功、禁止触发发送后续的BFRQ信息和BFRQ的SR中至少一项、解除所述触发发送后续的BFRQ信息和BFRQ的SR中至少一项的禁止。
