实施例1

在本实施例中提供了一种运行于上述移动终端的波束失败恢复的处理方法，图2是根据本发明实施例的一种波束失败恢复的处理方法的流程图，如图2所示，该流程包括如下步骤：
步骤S202，当频域带宽部分发生切换时，对波束失败恢复过程进行预定操作。
所述计时器包括如下计时器至少之一：波束失败检测计时器，波束失败恢复计时器，响应监听计时器。
所述计数器包括如下计数器至少之一：波束失败检测计数器、参考信号指示信息发送计数器。
在一实施例中，波束失败检测计时器用于控制连续两次波束失败指示之间的间隔。需要说明的是，如果该间隔的时间超过波束失败检测计时器大于该波 束失败检测计时器的计满时间，则说明连续的两次波束失败指示之间时间距离很远，因此，在后续过程中不再进行累加。
在一实施例中，波束失败恢复计时器，用于控制第一次启动新波束上报到本次波束失败恢复过程的时间长度。需要说明的是，如果该波束失败恢复计时器超时的话，即使没有成功发送新波束信息，终端也能够终止向基站发送新波束的信息。
在一实施例中，响应监听计时器，用于控制从终端发送一个PRACH(Physical Random Access Channel，物理随机接入信道)到终止监听基站的响应的时间。需要说明的是，如果该响应监听计时器超时的话，即使没有收到基站的响应，终端也不再进行监听，同时视为该PRACH序列发送失败。
在一实施例中，波束失败检测计数器，用于累计从物理层收到的波束失败指示。当该波束失败检测计数器达到预设的计数数量时，才认为波束失败事件发生，指示终端在选择新波束(即选择参考信号)，并根据选择的新波束关联的PRACH资源，向基站发送PRACH。
在一实施例中，在参考信号指示信息发送计数器计数超时，如果终端发送一个PRACH没有在SS-BFR(Synchronisation Signal-Beam Failure Recovery，同步信号波束失败恢复)中检测到PDCCH(Physical Downlink Control Channel，物理下行控制信道)，则计数加1。
需要说明的是，计时器参数即为计时器对应的最长时长，当计时器启动之后的时长超过所述计时器对应的最大时长，表示计时器超时。计数器参数即为计数器对应的阀值，当计数器的计数大于或者等于所述阀值时，进行预定操作。
在一实施例中，如果终端检测到在波束失败检测参考信号集合中的参考信号中存在至少一个参考信号的性能参数不小于预设的性能阈值，则视为没有检 测到波束失败，同时继续实时检测该波束失败检测参考信号集合中的参考信号。而如果波束失败检测参考信号集合中的全部参考信号的性能参数均小于该预设的性能阈值时，则视为检测到波束失败，同时终端的物理层向MAC(Media Access Control，介质访问控制)层上报波束失败指示信息。此时，波束失败检测计数器的计数值加1。
在此之后，如果选择的新波束的波束失败检测计数器的计数值达到预设的计数阈值的话，终端的MAC层指示物理层在候选参考信号集合中选择参考信号的性能参数大于预设的性能阈值的参考信号，同时将这些参考信号的资源索引信息以及参考信号的RSRP(Reference Signal Receiving Power，参考信号接收功率)上报给MAC层。

基于上述实施例，还提供了如下的应用场景，以便理解技术方案。
场景1:
图11是根据本发明实施例的一种实现波束失败恢复过程的流程图，如图11所示，波束失败恢复过程包括：
操作一：检测波束失败是否发生。终端通过检测波束失败检测参考信号集合中的参考信号，来检测波束失败是否发送。当波束失败检测参考信号集合中的参考信号中所有参考信号的性能都低于预定阀值时，终端的物理层向MAC层上报一个波束失败指示信息，当波束失败检测参考信号集合中的参考信号的性能至少有一个高于预定阀值时，认为没有检测到波束失败，终端的物理层不向MAC层上报波束失败指示信息，终端继续检测波束失败检测参考信号集合中参考信号的性能。MAC层收到物理层的一个波束失败指示信息后，启动或者重启波束失败检测计时器，将波束失败计数器加1，当波束失败检测计时器超时时，将波束失败检测计数器置0。
操作二：选择新波束。如果波束失败计数器达到预定值,终端的MAC层指示物理层在候选参考信号集合参考信号集合中选择参考信号的性能大于预定值的参考信号，将这些参考信号的资源索引信息以及参考信号的RSRP上报给 MAC层。
操作三：上报选择的新波束。MAC层在物理层上报的满足性能的多个参考信号中选择一个，将这个参考信号的索引上报给基站，在这之前基站给终端分配了候选参考信号集合中的参考信号和物理随机接入信道(Physical Random-access Channel，PRACH)资源之间的关联关系，从而终端就可以在选择的参考信号对应的PRACH资源上发送PRACH即发送preamble,基站收到这个PRACH信息之后就知道波束失败检测参考信号集合中的参考信号发生了波束失败，并知道终端在候选参考信号集合中选择的新波束(即所述选择的参考信号资源对应的波束)。以下为了简单将此种PRACH资源称为PRACH-BFR(Physical Random Access Channel-Beam Failure Recovery，物理随机接入信道波束失败恢复)。本文中所述上报参考信号指示信息，包括终端在上报资源(比如PRACH资源，PRACH资源也可以称为PRACH-BFR资源)上发送Preamble，或者终端在PUCCH中上报在候选参考信号集合中选择的参考信号指示信息。
操作四：监听针对上报的新波束信息的确认信息。终端上报选择的新波束信息之后，开启时域监听窗口，即开启监听响应计时器，监听基站发送的确认信息，从而知道基站收到了终端发送的选择的新波束信息，终端在配置的波束失败恢复控制信道资源(Control Resource Set-Beam Failure Recovery，CORESET-BFR)中包括的波束失败恢复搜索空间(Search Space-Beam Failure Recovery，SS-BFR)中监听基站发送的PDCCH。当在SS-BFR中监听到基站发送的PDCCH时，认为波束失败恢复的PRACH过程成功。当在时域监听窗口中即所述监听响应计时器运行期间时，没有在SS-BFR中检测到PDCCH，将PRACH发送次数增1，如果波束失败恢复计时器没有过期且PRACH发送次数没有超过预定值，则可以回到如上操作三继续进行，否则认为本次波束失败恢 复过程失败。从在SS-BFR中监听PDCCH到收到基站对于PDCCH的准共址参考信号的更新之前，终端认为PDCCH和PDSCH(Physical Downlink Shared Channel，物理下行共享信道)的DMRS(Demodulation Reference Signal，解调参考信号)和上报的新波束(即新参考信号)之间满足准共址关系。在波束失败恢复的PRACH过程成功之后直到收到基站对于PDCCH的准共址参考信号的更新之前，终端继续在SS-BFR中侦听PDCCH，PDCCH的准共址参考信号的更新包括如下更新至少之一：MAC-CE(Medium access control-Control Element，控制元素)命令对于PDCCH的准共址参考信号的更新，RRC(Radio Resource Control，无线资源控制)信令对于PDCCH的准共址参考信号列表的更新。终端收到基站对于PDCCH的准共址参考信号的更新之后，停止在SS-BFR中监听PDCCH。
NR允许基于频域带宽部分机制进行通信，一个上行CC中，最多可以配置4个候选频域带宽部分,一个时刻只能一个上行频域带宽部分处于激活状态，一个下行CC中，最多可以配置4个候选频域带宽部分，一个时刻只能一个下行频域带宽部分处于激活状态。
场景2：
在本场景中，假设N个下行频域带宽部分中都有各自对应的{波束失败检测参考信号集合，候选参考信号集合，波束失败恢复搜索空间}，N个频域带宽部分中的一个频域带宽部分切换到另一个频域带宽部分时，波束失败恢复过程提出如下增强方案。
波束失败恢复过程方式一：N个下行频域带宽部分对应相同的计时器和计数器，其中所述计时器包括：波束失败检测计时器、波束失败恢复计时器、监听响应计时器，计数器包括波束检测失败计数器、参考信号指示信息发送计数 器。当下行频域带宽部分切换之后，计时器、计数器不因为频域带宽部分切换而进行任何操作，实现无缝过度。计时器、计数器不因为频域带宽部分切换而进行终止或重启操作，只是波束失败恢复过程中的{波束失败检测参考信号集合，候选参考信号集合}进行更新替换。
图12是根据本发明实施例的波束失败指示信息上报周期中包括BWP切换的示意图一。如图12所示，从频域带宽部分BWPD0切换到频域带宽部分BWPD1，波束失败恢复过程中的{波束失败检测参考信号集合，候选参考信号集合}从频域带宽部分BWPD0中的{波束失败检测参考信号集合0，候选参考信号集合0}更新为频域带宽部分BWPD1中的{波束失败检测参考信号集合1，候选参考信号集合1}，即在频域带宽部分BWPD0处于激活态时，只有波束失败检测参考信号集合0中的参考信号的性能都低于预定阀值时，物理层向MAC层上报波束失败指示信息，波束失败计数器累积到预定值时，从候选参考信号集合0中选择新波束。从频域带宽部分BWPD0切换到频域带宽部分BWPD1之后，只有波束失败检测参考信号集合1中的参考信号的性能都低于预定阀值时，物理层向MAC层上报波束失败指示信息，波束失败计数器累积到预定值时，从候选参考信号集合1中选择新波束。从而频域带宽部分BWPD0切换到频域带宽部分BWPD1之前，如果波束失败计数器已经累积到一个值比如为3，只是这个值小于预定阀值6，切换到频域带宽部分BWPD1之后，在原来波束失败计数器的基础上继续累积，即切换到频域带宽部分BWPD1之后波束失败计数器的值初始值为3。
此时存在如下情况，一个波束失败指示信息的上报周期中包括频域带宽部分切换，此时可以约定终端根据新频域带宽部分中的波束失败检测参考信号集合决定是否上报波束失败指示信息，或者约定根据波束失败指示信息的上报周 期包括的对应处于激活状态时间长度的频域带宽部分中的波束失败检测参考信号集合决定是否上报波束失败指示信息。如图7中所示，一个波束失败指示信息的上报周期中频域带宽部分BWPD0处于激活状态的时间大于频域带宽部分BWPD1处于激活状态的时间，从而在此上报周期中，根据频域带宽部分BWPD0中配置的波束失败检测参考信号集合0中的参考信号的性能是否都低于预定值，判断是否上报波束失败指示信息给MAC层。
图13是根据本发明实施例的波束失败指示信息上报周期中包括BWP切换的示意图二。如图13所示，图13中一个波束失败指示信息的上报周期中频域带宽部分BWPD2处于激活状态的时间大于频域带宽部分D0处于激活状态的时间，从而在此上报周期中，根据频域带宽部分BWPD2中配置的波束失败检测参考信号集合2中的参考信号的性能是否都低于预定值，判断是否上报波束失败指示信息给MAC层。
此时的另一种实施方式，通过建立新旧频域带宽部分中的波束失败检测参考信号集合、候选参考信号集合之间的对应关系，比如旧频域带宽部分中的波束失败检测参考信号集合中包括的参考信号(1,2)，新频域带宽部分中的波束失败检测参考信号集合中包括参考信号(3,4)，其中参考信号1和3之间满足QCL(Quasi-co-location，准共址)关系，参考信号2和4之间满足QCL关系，认为存在QCL关系的两个参考信号对应基站的同一个发送波束，可以虚拟为一个参考信号，从而综合参考信号(1,3)得到一个链路性能称为第一链路性能，综合参考信号(2,4)得到一个链路性能称为第二链路性能，当第一链路性能和第二链路性能都低于预定链路性能阀值时，物理层向MAC层发送波束失败指示信息。上述是通过QCL关系建立两个新旧频域带宽部分中的波束失败检测参考信号集合中的参考信号之间的对应关系，当然也可以通过其他规则或者基站通知的显式信令 建立参考信号之间的对应关系。
类似地，候选参考信号集合的检测也可以采用上述波束失败检测参考信号集合的检测方法，比如建立新旧频域带宽部分中的候选参考信号集合中的参考信号之间的对应关系，比如旧频域带宽部分中的候选参考信号集合包括参考信号(5,6)，新频域带宽部分中的候选参考信号集合包括参考信号(7,8)，通过QCL关系或者显式信令，得知参考信号(5,7)存在对应关系(比如对应相同的发送波束1)，参考信号(6,8)存在对应关系(比如对应相同的发送波束2)，从而终端就可以基于参考信号(5,7)综合得到这个发送波束1对应的性能，基于参考信号(6,8)得到参考信号(6,8)对应的发送波束2的性能，从而在发送波束1和发送波束2之间选择一个优选发送波束发送给基站。
建立新旧频域带宽部分中的参考信号之间的对应关系，也可以是当两个或者两个以上的候选参考信号(所述候选参考信号即为候选参考信号集合中的参考信号)关联到同一个PRACH资源时，认为所述两个或者两个以上的候选参考信号存在对应关系，当终端在所述一个PRACH资源上发送Preamble码之后(本场景发送PRACH即在PRACH信道上发送preamble码)，基站就知道终端是基于与这个PRACH关联的两个或者两个以上的参考信号得到的新波束选择结果。上述关联到同一个PRACH资源的两个或者两个以上的参考信号对应不同的频域带宽部分。
上述波束失败恢复过程方式一中，随着频域带宽部分的切换，波束失败过程不因此而中断，即多个频域带宽部分之间的波束失败检测参考信号集合、候选参考信号集合之间有关联，对应同一套波束失败恢复过程。
图14是根据本发明实施例的多个频域带宽部分对应一个波束失败过程的示意图一。如图14所示，频域带宽部分BWPD0和频域带宽部分BWPD1共享一 个波束失败恢复过程，即对应同一个波束失败检测计时器。波束失败恢复计时器、监听计时器、波束失败计数器、参考信号指示信息发送计数器，这些计时器、计数器不因为频域带宽部分的切换而进行额外的操作，比如不进行如下的操作置0/停止/暂停/重启等，只是频域带宽部分切换之后，将波束失败恢复过程中的波束失败检测参考信号集合、候选参考信号集合更新为切换之后的频域带宽部分中的波束失败检测参考信号集合、候选参考信号集合。当然，如果切换之后的频域带宽部分中没有波束失败检测参考信号集合(或者候选参考信号集合)，在一实施例中，波束失败检测参考信号集合和候选参考信号集合中至少一个就不进行更新。比如频域带宽部分切换之后，在旧频域带宽部分中发送了Preamble之后，在新频域带宽部分的SS-BFR中侦听PDCCH，从而确定终端发送的PRACH基站有没有收到。旧频域带宽部分中已经发送了PRACH，但是监听计时器到期时，还没有在旧频域带宽部分中的SS-BFR中监听到PDCCH，而且参考信号指示信息发送计数器还没有达到预定次数，基站在其他SS(Search Space，搜索空间)中的DCI中又触发了频域带宽部分切换，此时终端在新频域带宽部分中可以继续PRACH的发送。
波束失败恢复过程方式二：图15是根据本发明实施例的一种多个频域带宽部分对应一个波束失败过程的示意图二。如图15所示，下行频域带宽部分切换之后，波束失败检测计时器、波束失败恢复计时器停止，波束失败计数器置0，参考信号指示信息发送计数器置0，终端在新的频域带宽部分中重新启动图1所示的波束失败恢复过程，直到在新的频域带宽部分中，终端的MAC层收到物理层反馈的波束失败指示信息之后，采用图1中的流程，启动波束失败检测计时器、波束失败恢复计时器，对于波束失败计数器进行累加。类似地，当频域带宽部分切换之后，也是在新频域带宽部分中的候选参考信号集合中选择参考信 号。
上述波束失败恢复过程方式一和方式二中，可以理解多个下行频域带宽部分对应一套波束失败检测计时器、波束失败恢复计时器、监听计时器、波束失败计数器、参考信号指示信息发送计数器，不同之处是频域带宽部分切换之后，不同频域带宽部分上的计数器/计时器是否有关联，比如波束失败计数器是否在新频域带宽部分中进行继续累加，如果可以累加就是方式一，否则为方式二，频域带宽部分切换之后PRACH的发送过程是否要重启，如果重启就是方式二，如果不重启就是方式一。不同下行频域带宽部分中对应的如下配置信息至少之一要相同：波束失败检测计时器、监听计时器、波束失败恢复计时器、波束失败计数器、参考信号指示信息发送计数器。或者多个下行频域带宽部分中只有一个频域带宽部分中配置了一套波束失败检测计时器、监听计时器、波束失败恢复计时器、波束失败计数器、参考信号指示信息发送计数器，所述多个下行频域带宽部分共享此参数。终端上报的preamble信息中不需要携带频域带宽部分信息。在下面的实施方式中，不同频域带宽部分各自对应各自的波束失败恢复过程。各个频域带宽部分中这些参数的配置之间不需要满足约束条件。
波束失败恢复过程方式三：图16是根据本发明实施例的多个下行频域带宽部分各自对应各自波束失败恢复过程的示意图一。图17是本发明实施例的多个下行频域带宽部分各自对应各自波束失败恢复过程的示意图二。如图16和17所示，如有2个下行频域带宽部分，各自对应一个波束失败过程，即各自有对应的{波束失败检测计时器、波束失败恢复计时器、监听计时器、波束失败计数器、参考信号指示信息发送计数器}。当发生频域带宽部分切换时，旧频域带宽部分中的波束失败检测计时器不因为频域带宽部分切换而进行操作，旧频域带宽部分中的波束失败计数器暂停累加，直到重新切换到这个旧频域带宽部分中， 如图17所示。在重新切换到旧频域带宽部分之前，如果旧频域带宽部分对应的波束失败检测计时器过期，则此频域带宽部分对应的波束失败计数器置0，如图16所示。新频域带宽部分中的波束失败检测计时器不因为频域带宽部分切换而做任何操作，新频域带宽部分中之前被暂停累加的波束失败计数器可以开启继续累加，当然如果这个暂停的波束失败计数器在这个频域带宽部分连续两次处于激活状态的间隔内，这个频域带宽部分的波束失败检测计时器已经过期，则该新频域带宽部分被暂停累加的波束失败计数器已经置0。如果当前切换到的新频域带宽部分是第一次处于激活状态，则对于新频域带宽部分启动图16所示的流程，直到收到基于新频域带宽部分中的波束失败检测参考信号集合得到的波束失败指示信息之后，按照图16所示的流程，进行波束失败检测计时器、波束失败恢复计时器、波束失败计数器的相关操作。总之认为此时各个频域带宽部分各自对应一套独立的图16中的流程。在上述实施方式中，在新BWP(即切换后的BWP，如图16至17中的BWPD1)处于激活状态的时间段，针对旧BWP(即切换前的BWP，如图16至17中的BWPD0)的波束失败恢复过程除波束失败检测计时器继续运行之外，其余的计时器(包括波束失败恢复计时器、监听计时器)是暂停的，计数器(包括波束失败检测计数器，参考信号指示信息发送次数计数器)也是暂停累加的，等到再次切换到BWPD0之后，再开启这些计时器、计数器。比如图16中的t1至t5时间段(或者t11至t5时间段)中和图17中t1至t4时间段(或者t11至t4时间段)中，0(即所示波束失败恢复计时器0),0(即所示监听计时器0)是暂停的，0(即所示波束失败检测计数器0),0(即所示参考信号指示信息发送次数计数器)也是暂停累加的，图16中的t6时刻和图17中的t2时刻，0,0,0,0]解锁。
波束失败恢复过程方式四：新旧BWP分别对应一个波束失败恢复过程，和 方式三不同的是，在新BWP处于激活状态时间段中，针对旧BWP的波束失败过程还在继续允许，比如图16中的t1至t5时间段(或者t11至t5时间段)中和图17中t1至t4时间段(或者t11至t4时间段)中,0,0是继续运行的，和/或0,0也是继续运行的，比如旧BWP的波束失败检测参考信号在新BWP中对应的参考信号，旧BWP的候选参考信号在新BWP中对应的参考信号。从而在新BWP中，至少有两个波束失败恢复过程在并行运行，因为可能旧BWP之前的BWP的波束失败恢复过程也可能在当前新BWP中运行，当然也可以规定一个BWP中并行运行的波束失败恢复过程的最大数目个数，比如针对旧BWP的波束失败恢复过程称为过程1，针对新BWP的波束失败恢复过程称为过程2，在新BWP中需要有至少两套上报资源、两套波束失败恢复搜索空间，分别针对过程1和过程2。比如有两套PRACH资源{PRACH-BFR1，PRACH-BFR-2}、两套SS-BFR{SS-BFR1，SS-BFR-2}，分别针对过程1和过程2，SS-BFRi的准共址参考信号和SS-BFRi中的DCI调度的PDSCH的准共址参考信号都为过程i中上报的参考信号指示信息，i＝1,2，SS-BFRi中的DCI调度的PUSCH/PUCCH的空间滤波参数为过程i中上报参考信号指示信息所用的空间滤波参数，即在PRACH-BFR资源中发送preamble所用的preamble。其中SS-BFRi中的DCI调度的PUCCH包括SS-BFRi中的DCI调度的PDSCH的ACK/NACK(Acknowledgement/Negative Acknowledgement，应答/非应答)消息所在的PUCCH。另一种实施方式是在新BWP中只有一套PRACH-BFR和一套SS-BFR针对过程2，新BWP中运行的针对其他BWP的波束失败恢复过程的参考信号指示信息上报可以在新BWP中的高层信令中携带，比如MAC-CE/RRC信令。第三种实施方式中，{波束失败检测参考信号集合，候选参考信号集合，PRACH-BFR}是新旧BWP各对应一套，SS-BFR只有一套，SS-BFR的DCI中 或者SS-BFR中的DCI调度的PDSCH中携带过程索引信息，或者候选参考信号集合的套索引信息。
图16中BWP切换时的波束失败恢复过程相关操作是在t1时刻进行，当然也可以是在t11时刻进行。类似地，t5时刻进行的动作也可以在t6时刻进行。图17中BWP切换时的波束失败恢复过程相关操作是在t1时刻进行，当然也可以是在t11时刻进行，类似地，t4时刻进行的动作也可以在t2时刻进行。
在图16至17中，各个BWP分别对应一套独立的波束失败恢复过程，当一个PRACH资源关联多于一个候选参考信号时，不同候选参考信号属于不同BWP中的候选参考信号集合，终端在这个PRACH发送preamble之后，终端和基站约定距离当前PRACH资源最近的处于激活状态的下行BWP是哪个，PRACH资源上报的参考信号指示信息就是针对哪个下行BWP中的候选参考信号集合的。
在上述三种波束失败恢复过程中，波束失败检测计时器、监听计时器、波束失败恢复计时器、波束失败计数器、参考信号指示信息发送计数器都按照上述三种波束失败恢复过程中的其中一种进行，当然本场景也不排除，部分计时器和部分计数器中至少之一按照上述方式i做，部分计时器和部分计数器中至少之一按照上述方式j做，其中i、j是属于{1,2,3}且不相等的正整数。比如波束失败检测计时器、波束失败计数器按照方式一做，波束失败恢复计时器、监听计时器、参考信号指示信息发送计数器按照关联关系建立方式二操作。
场景3：
在本场景中，N个下行频域带宽部分中配置了{波束失败检测参考信号集合，波束失败检测计时器，波束失败计数器}，M个上行频域带宽部分中配置了{候选参考信号集合，PRACH，候选参考信号集合与PRACH之间的关联关系，波束失败恢复计时器，SS-BFR，监听计时器，参考信号指示信息发送计数器}，目 的在于需要确认它们之间的对应关系。其中，计时器的参数用于配置计时器的时长，所述计数器的参数用于配置计数器对应的预定阀值，当计数器的计数达到与所述计数器对应的预定阀值时，进行预定操作。
在TDD(Time Division Duplexing，时分双工)的一个激活CC中下行频域带宽部分的个数和上行频域带宽部分的个数应该是相同的，但是还是会存在N和M不同的情况，比如只有部分上行频域带宽部分中配置了波束失败恢复参数和只有部分下行频域带宽部分中配置波束失败恢复参数中至少之一的情况，需要确定M个上行频域带宽部分中的波束失败恢复参数和N个下行频域带宽部分波束失败恢复参数之间的对应关系。从而可以确定终端在一个PRACH资源发送Preamble是因为以下至少之一：在哪些下行频域带宽部分中检测到了波束失败检测参考信号集合中的参考信号的性能低于预定门限；在哪些下行频域带宽部分中检测到了候选参考信号集合。比如，上行频域带宽部分(即表1中的频域带宽部分U)和下行频域带宽部分(即表1中的频域带宽部分D)中BFR参数的配置如表1所示。在表1中为了描述简单，将一个上行频域带宽部分中配置的七个参数{候选参考信号集合，PRACH，候选参考信号集合与PRACH之间的关联关系，波束失败恢复计时器，SS-BFR，监听计时器，参考信号指示信息发送计数器}称为一个BFR-U参数集合(即所述第二类波束失败恢复参数)，将一个下行频域带宽部分中配置的三个参数{波束失败检测参考信号集合，波束失败检测计时器，波束失败计数器}称为一个BFR-D参数集合(即所述第一类波束失败恢复参数)。在表1中BFR-Ui表示第i套BFR-U参数集合，其中i＝0,1，BFR-Dj表示第j套BFR-D参数集合，其中j＝0,1,2。表1中频域带宽部分Ui表示第i个频域带宽部分U，i＝0至3，表1中频域带宽部分Uj表示第j个频域带宽部分D，j＝0至3。
在FDD(Frequency Division Duplexing，频分双工)系统中，上行CC中的4个候选频域带宽部分U中的一个频域带宽部分U和下行CC中的4个候选频域带宽部分D中的每个频域带宽部分D都可能在相同时刻处于激活状态。
表1
频域带宽部分索引 BFR的配置情况
频域带宽部分U0 BFR-U0
频域带宽部分U1 BFR-U1
频域带宽部分U2 没有配置BFR参数
频域带宽部分U3 没有配置BFR参数
频域带宽部分D0 BFR-D0
频域带宽部分D1 BFR-D1
频域带宽部分D2 没有配置BFR参数
频域带宽部分D3 BFR-D3
可以采用如下方式中的一种或者多种确定N个BFR-U和M个BFR-D之间的对应关系，比如表1中的2个BFR-U参数集合和3个BFR-D参数集合之间的对应关系。确定了对应关系之后，基站在哪个频域带宽部分U上收到PRACH，就可以通过上述对应关系确定以下至少之一：终端通过检测哪个频域带宽部分D中的波束失败检测参考信号集合检测到了波束失败事件发生(即哪个频域带宽部分D对应的波束失败计数器的计数达到预定值)；终端在哪个频域带宽部分D中的候选参考信号集合选择到了新波束。确定对应关系之后，终端也知道当基于一个波束失败检测参考信号集合检测到波束失败事件发生之后，执行以下至少之一操作：要求到哪个频域带宽部分D上的候选参考信号集合中选择新波束和要求到哪个频域带宽部分U上报新波束。
确定方式一：具有相同频域带宽部分-ID中的上行频域带宽部分的BFR-U参数集合和下行频域带宽部分的BFR-D参数之间具有对应关系。即终端要在上行频域带宽部分U0中的PRACH-BFR上发送Preamble，只因为在频域带宽部分D0中的波束失败检测参考信号集合中的参考信号性能都低于预定值。从而频域带宽部分D3中配置的波束失败检测参考信号集合终端就不需要检测，因为BFR-D参数集合3中的波束失败检测参考信号集合中的参考信号都低于预定门限时，因为没有BRACH-BFR与此波束失败检测参考信号集合对应，从而终端不能在任何PRACH-BFR上发送preamble，从而终端也不需要检测BFR-D参数集合3中的波束失败检测参考信号集合，即此时要求一个下行频域带宽部分中配置了BFR-D参数集合，和这个下行频域带宽部分具有相同频域带宽部分-ID的上行频域带宽部分中就需要配置BFR-U参数集合。终端不希望收到如下的配置，一个下行频域带宽部分中配置了BFR-D参数集合，和这个下行频域带宽部分具有相同频域带宽部分-ID的上行频域带宽部分中没有配置BFR-U参数集合，即要求一个上行频域带宽部分中配置了BFR-U参数集合，和这个上行频域带宽部分具有相同频域带宽部分-ID的下行频域带宽部分中就需要配置BFR-D参数集合。终端不希望收到如下的配置，一个上行频域带宽部分中配置了BFR-U参数集合，和这个上行频域带宽部分具有相同频域带宽部分-ID的下行频域带宽部分中没有配置BFR-D参数集合，即配置了BFR-D的频域带宽部分D集合和配置了BFR-U的频域带宽部分U集合中的频域带宽部分之间存在一一对应关系。
确定方式二：一个配置了BFR-U参数集合的频域带宽部分U和一个CC中配置了BFR-D参数集合的所有频域带宽部分D之间存在对应关系，任意一个BFR-D中的波束失败检测参考信号集合中的参考信号低于预定阀值，就可以在这个BFR-U参数集合中配置的PRACH资源上发送preamble。比如当前处于激 活状态的是频域带宽部分D3和频域带宽部分U3，通过检测频域带宽部分D3中的BFR-D3中的参数检测得到波束失败事件发生，即BFR-D-3中的波束失败计数器达到波束失败计数器对应的预定阀值。此时由于频域带宽部分U3中没有配置BFR-U参数集合，从而终端需要切换到一个配置了BFR-U参数集合的频域带宽部分U中，但是由于有2个频域带宽部分U:{频域带宽部分U0，频域带宽部分U1}配置了BFR-U参数集合，为此终端可以基于频域带宽部分索引信息，选择切换到哪个频域带宽部分U中，比如切换到配置了BFR-U参数集合的多个频域带宽部分中具有较低频域带宽部分-ID的频域带宽部分U中，比如切换到频域带宽部分U0中，在频域带宽部分U0中终端根据在候选参考信号集合中选择的新参考信号指示信息确定在哪个PRACH资源上发送preamble。终端需要切换到配置了BFR-U参数集合的频域带宽部分U集合的哪个频域带宽部分U的另一种决策方式是，终端根据选择的新参考信号指示信息确定切换到哪个频域带宽部分U中，比如表1中的BFR-U0中的候选参考信号集合包括参考信号(1,2)，BFR-U1中的候选参考信号集合包括参考信号(2,3)，终端可以在参考信号(1,2,3)中选择参考信号(即新的参考信号指示信息)，基于选择的参考信号确定切换到哪个频域带宽部分U中，比如选择的参考信号只有一个频域带宽部分U中有，则切换到这个频域带宽部分U中，比如选择参考信号1则切换到频域带宽部分U0中，选择参考信号3，则切换到频域带宽部分U1中，选择参考信号2则可以切换到具有最低频域带宽部分-ID的频域带宽部分U中。
确定方式三：相同时刻处于激活状态的频域带宽部分U和频域带宽部分D之间具有对应关系，或者更确切地说，相同时刻处于激活状态的频域带宽部分U和频域带宽部分D，频域带宽部分U中的BFR-U参数集合和频域带宽部分D中的BFR-D参数集合之间具有对应关系。在FDD中，一个下行频域带宽部分可 以和上行CC中的候选频域带宽部分中的每一个频域带宽部分在相同时刻处于激活状态，因为它们是独立进行频域带宽部分切换的，比如下行CC中包括4个频域带宽部分，上行CC中包括3个上行频域带宽部分，一个上行频域带宽部分处于激活状态期间的不同时间段下行处于激活状态的频域带宽部分可以不同。图18是根据本发明实施例的多个下行频域带宽部分各自对应各自波束失败恢复过程的示意图三。如图18所示，只要终端在频域带宽部分D0、频域带宽部分D1、频域带宽部分D2、频域带宽部分D3中的任何一个频域带宽部分D中的BFR-D参数集合检测到波束失败事件，都可以在BFR-U0中配置的候选参考信号集合中选择的参考信号指示信息中选择新参考信号指示信息，并根据选择的新参考指示信息在频域带宽部分U0中的对应的PRACH资源发送preamble。频域带宽部分U0中配置的BFR-U0中一个PRACH资源需要关联x个候选参考信号集合，不同的候选参考信号对应{频域带宽部分D0，频域带宽部分D1，频域带宽部分D2，频域带宽部分D3}中的不同频域带宽部分D，其中x为小于或者等于4的正整数。即x为小于或者等于一个CC中包括的下行候选频域带宽部分集合中包括的频域带宽部分个数。类似地，图19是根据本发明实施例的下行BWP的示意图。如图19所示，一个下行BWP处于激活状态期间的不同时间段上行处于激活状态的BWP可以不同。
确定方式四：根据频域带宽部分U中配置的SS-BFR信息确定这个频域带宽部分U中的BFR-U参数集合和BFR-D参数集合之间的对应关系。比如频域带宽部分U0中的BFR-U参数集合中的SS-BFR搜索空间位于频域带宽部分D1中，则频域带宽部分U0中的BFR-U参数集合和频域带宽部分D1中的BFR-D参数集合之间具有对应关系。
确定方式五：根据频域带宽部分U中配置的候选参考信号集合信息确定这 个频域带宽部分U中的BFR-U参数集合和BFR-D参数集合之间的对应关系。比如频域带宽部分U0中的BFR-U参数集合中的候选参考信号集合包括的参考信号位于频域带宽部分D1中，则频域带宽部分U0中的BFR-U参数集合和频域带宽部分D1中的BFR-D参数集合之间具有对应关系。
确定方式六：显式信令确定。比如通过显式信令确定N个BFR-U参数集合和M个配置BFR-D参数集合之间的对应关系，比如在BFR-Ui的配置信息中包括BFR-Dj的索引信息。
上述实施方式中，第一类波束失败恢复参数为BFR-D参数集合，第二类波束失败恢复参数为BFR-U参数集合。类似地，上述N套第一类波束失败恢复参数和M套第二类波束失败恢复参数的对应关系的确定方法，还可以包括如下情况：
情况一：第一类波束失败恢复参数属于{波束失败检测参考信号集合，波束失败检测计时器，波束失败计数器}，第二类波束失败恢复参数属于{候选参考信号集合}。当基于一套参数{波束失败检测参考信号集合，波束失败检测计时器，波束失败计数器}检测到了波束失败事件发生，终端就知道基于哪一套{候选参考信号集合}去选择新波束。
情况二：第一类波束失败恢复参数属于{候选参考信号集合}，第二类波束失败恢复参数属于{候选参考信号集合与PRACH之间的关联关系，波束失败恢复计时器，监听计时器，参考信号指示信息发送计数器}，当基于一套参数{候选参考信号集合}选择到新波束之后，终端就知道基于哪一套{候选参考信号集合与PRACH之间的关联关系，波束失败恢复计时器，监听计时器，参考信号指示信息发送计数器}去上报新波束指示信息。
情况三：第一类波束失败恢复参数属于{候选参考信号集合与PRACH之间 的关联关系，波束失败恢复计时器，监听计时器，参考信号指示信息发送计数器}，第二类波束失败恢复参数属于{SS-BFR}，当基于一套参数{候选参考信号集合与PRACH之间的关联关系，波束失败恢复计时器，监听计时器，参考信号指示信息发送计数器}上报新波束之后，终端就知道基于哪一套{SS-BFR}去上报新波束指示信息。
在本场景中，所述一套第一类波束失败恢复参数对应的频域带宽部分，表示根据所述第一类波束失败恢复参数确定的信号或者信道位于所述频域带宽部分中，所述一套第二类波束失败恢复参数对应的频域带宽部分，表示根据所述第二类波束失败恢复参数确定的信号或者信道位于所述频域带宽部分中。
场景4：
在一个频域带宽部分U中的波束失败恢复配置(Beam Failure Recovery Config)包括：候选参考信号集合、PRACH、候选参考信号集合与PRACH之间的关联关系、波束失败恢复计时器、SS-BFR、监听计时器、参考信号指示信息发送计数器。
如果对于SS-BFR没有限制，那SS-BFR可以位于下行候选频域带宽部分集合中的任意一个频域带宽部分中，这在本场景下并不合适。因为进行PRACH过程中，终端要么不进行频域带宽部分切换，要么切换到新频域带宽部分之后，还要进行新的PRACH过程。为此，当终端在PRACH上发送preamble之后，需要监听基站的响应信息，在此过程中如果终端不切换上行频域带宽部分，在TDD系统中下行频域带宽部分也不能切换，为此就需要限制一个频域带宽部分U中的波束失败恢复配置中配置的SS-BFR所在的频域带宽部分D需要和上述频域带宽部分U具有相同频域带宽部分-ID信息。
在FDD系统中，一个上行频域带宽部分U中配置的SS-BFR可以没有如上 约束，为此可以有如下配置方法：
配置方法一：一个频域带宽部分U中配置多个SS-BFR，其中不同的SS-BFR落在不同的频域带宽部分D中。需要一个频域带宽部分U中包括为下行CC中的每个频域带宽部分D配置的SS-BFR，因为一个频域带宽部分U在其激活状态的不同时间段下行处于激活状态的频域带宽部分D可以不同，从而一个下行频域带宽部分U可以和下行候选频域带宽部分中的任何一个在相同时刻处于激活状态。这样配置之后，终端发送preamble之后，不用切换下行频域带宽部分就可以侦听基站发送的RAR(Random Access Response，随机接入响应)信息。
配置方法二：一个频域带宽部分U中配置的SS-BFR可以位于任意一个频域带宽部分D上，当终端在PRACH-BFR资源上发送preamble之后，如果SS-BFR不位于当前激活的频域带宽部分D中，则将下行频域带宽部分切换到SS-BFR所在的频域带宽部分D。一个频域带宽部分U中只配置一个SS-BFR，也可以配置多个SS-BFR，当终端在PRACH-BFR资源上发送preamble之后，如果这个PRACH-BFR所在的频域带宽部分U中配置的SS-BFR集合中有落在当前激活频域带宽部分D中的SS-BFR，则基于当前激活频域带宽部分D对应的SS-BFR中监听RAR信息，否则将频域带宽部分D切换到该频域带宽部分U中配置的SS-BFR集合中的一个SS-BFR所在的频域带宽部分D上，比如切换到具有最低SS-BFRID的SS-BFR所在的频域带宽部分D中。
场景5
在本实施例中，在第一时间段，比如终端从在SS-BFR中监听PDCCH到收到基站在预定信道中(所述预定信道包括SS-BFR中传输的PDCCH和SS-BFR中的PDCCH调度的PDSCH中至少之一)对于PDCCH的准共址参考信号的更新之前，终端认为SS-BFR中的PDCCH和SS-BFR中调度的PDSCH的DMRS (Demodulation Reference Signal，解调参考信号)和上报的新波束(即新参考信号，也即本文所述参考信号指示信息中指示的参考信号)之间满足准共址关系。在第一时间段中其他控制信道和其他控制信道调度的数据信道的准共址参考信号还是按照原配置进行，不会跟着参考信号指示信息而改变。
在第一时间段中，在其他控制信道或者其他控制信道调度的数据信道中收到对于PDCCH的准共址参考信号的更新，但是没有在SS-BFR或者SS-BFR调度的数据信道中收到对于PDCCH的准共址参考信号的更新之前，第一时间段没有结束，终端认为SS-BFR中的PDCCH和SS-BFR中调度的PDSCH的DMRS和上报的新波束之间满足准共址关系。
在第一时间段中，如果SS-BFR和其他控制信道发生冲突，SS-BFR的优先级更高，或者第一时间段中，如果SS-BFR和第一类控制信道发生冲突，SS-BFR的优先级更高，所述第一类控制信道至少和波束失败检测参考信号集合中的一个参考信号满足准共址关系，比如至少和波束失败检测参考信号集合中的一个参考信号关于空间接收参数满足准共址关系。
在第一时间段中，终端继续在SS-BFR中侦听PDCCH，PDCCH的准共址参考信号的更新包括如下更新至少之一：MAC-CE命令对于PDCCH的准共址参考信号的更新、RRC信令对于PDCCH的准共址参考信号列表的更新。终端收到基站对于PDCCH的准共址参考信号的更新之后，停止在SS-BFR中监听PDCCH。
因为只有在第一时间段中才会在SS-BFR中侦听PDCCH，而且这段时间中SS-BFR中的PDCCH和SS-BFR中的PDCCH调度的PDSCH的准共址参考信号都为参考信号指示信息指示的，为此可以有如下至少之一的约定：SS-BFR中只监听专有PDCCH、SS-BFR中的PDCCH中只监听DCI1_0/DCI1_1、SS-BFR 中的DCI1_1中tci-PresentInDCI不使能、SS-BFR中的DCI0_1中的SRS资源指示(SRS Resource Indicator，SRI)比特域的比特数为0，不根据SRS-set for codebook或者SRS-set for non codebook中包括的SRS资源数确定比特数，其中SRS资源指示(resource indicator)用于指示PUSCH的预编码/空间发送滤波参数根据哪个SRS资源获取，具体地可以参考5G新空口标准协议中的协议38.212。
当然本实施例也不排除SS-BFR中的DCI中其他比特域进行简化处理，比如时域资源指示域，CSI(Channel State Information，信道状态信息)请求(request)域等，甚至SS-BFR中在响应计时器运行期间只发送一个序列，仅指示基站收到了终端发送的preamble。比如可以发送一个DMRS序列，当PDCCH的DMRS序列为第一序列时，表示基站只发送了这个序列，没有发送PDCCH，当PDCCH的DMRS序列为第二序列时，表示基站不但发送了DMRS，也发送了PDCCH，从而可以适应当基站收到preamble之后，只是给终端一个响应，并不调度PDSCH/PUSCH/PUCCH。在波束失败恢复计时器运行期间按照此规则进行，所述终端收到所述参考信号序列，表示根据所述参考信号序列(也可以称为参考信号端口)得到的SINR(Signal to Interference plus Noise Ratio，信号与干扰加噪声比)，根据控制信道的传输参数假设，得到控制信道BLER的预测值低于预定门限。当终端在SS-BFR中收到预定参考信号序列或者PDCCH就表示preamble的发送成功，停止波束失败恢复计时器。
当然第一时间段还可以是如下时间段之一：响应监听计时器运行期间、波束失败恢复计时器运行期间、从发送参考信号指示信息之后直到收到控制信道的准共址参考信号的更新消息之前、从发送参考信号指示信息之后直到在波束失败恢复控制信道中收到控制信道。
多个下行信道或信号有冲突包括如下情况至少之一：
情况一：多个信道或信号占有的资源的交集非空，所述资源包括如下至少之一：时域资源、频域资源、码域资源、空域资源、天线端口，其中一个空域资源对应一个准共址参考信号。
情况二：所述多个信道或信号占有的空域资源终端不能同时产生或者多个信道或信号占有的空域资源的差集非空，比如一个时刻终端只能产生1个接收波束，当这多个信道或信号不满足准共址关系时，这多个信道或信号就发生冲突。比如一个时刻终端只能产生2个接收波束，当这多个信道或信号的准共址参考信号不满足准共址关系且多于2个时，这多个信道或信号发生冲突。
情况三：多个控制信道资源有冲突还包括多个控制信道资源中包括候选控制信道的个数和超过第一通信节点在一个时间单元中能够盲检的候选控制信道的个数。
当多个信道或信号发生冲突时，只接收优先级高的信道或信号，或者以优先级高的信道或信号的参数接收所述多个信道或信号。
场景6
在本实施例中，在第二时间段中，携带参考信号指示信息的信道或信号与其他信道或信号有冲突时，携带参考信号指示信息的信道或信号优先级更高，比如PRACH-BFR中的preamble和其他控制信道调度的上行信道或信号发生冲突，或者Preamble和之前已经配置的周期性PUCCH发生冲突。
在第二时间段中，波束失败恢复控制信道资源中的控制信道调度的上行信道或信号的空间滤波参数根据发送参考信号指示信息的空间滤波参数获取，其中波束失败控制信道资源表示SS-BFR，或者SS-BFR所在的CORESET(Control-resource Set，控制资源集)。其中所述上行信道包括PUCCH和PUSCH中至少之一，上行信号包括SRS、PRACH、SR(Scheduling Request，调度请求)。 比如在第二时间段中，PUSCH对应的SRS-set(for non codeboo和codebook中至少之一)更新为只包括发送参考信号指示信息的preamble。
其中第二时间段包括以下时间段至少之一：响应监听计时器运行期间、波束失败恢复计时器运行期间、从发送参考信号指示信息之后直到收到上行信道或信号的空间滤波参数的更新消息之前、从发送参考信号指示信息之后直到在波束失败恢复控制信道资源中的控制信道的数据信道中收到上行信道或信号的空间滤波参数的更新消息之前、从发送参考信号指示信息之后直到在波束失败恢复控制信道中收到控制信道。
其中所述多个上行信道或信号有冲突包括如下情况至少之一：
情况一：多个信道或信号占有的资源的交集非空，所述资源包括如下至少之一：时域资源、频域资源、码域资源、空域资源、天线端口、天线资源。其中一个空域资源关联一个空间发送滤波参数的参考信号。
情况二：所述多个信道或信号占有的空间发送滤波参数终端不能同时产生，比如多个信道或信号的空间滤波参数关联的参考信号终端不能同时发送，比如多个空间发送滤波参数的参考信号属于一个SRS set。
当多个信道或信号发生冲突时，只发送优先级高的信道或信号，或者以优先级高的信道或信号的参数发送所述多个信道或信号。
场景7
在本实施例中，波束失败检测参考信号集合q 0通过隐式方法获取，比如通过CORESET中的配置的关联空间接收滤波参数的准共址参考信号获取。一个BWP中或者一个CC中配置了H个CORESET，每个CORESET中可以配置该CORESET传输的PDCCH的准共址参考信号，而q 0中最多包括F个参考信号， 如何从H个CORESET中选择F个CORESET，从而得到q 0中包括的参考信号，可以采用如下规则中的一种或者多种选择所述F个CORESET。
规则一：所述F个控制信道资源不包括波束失败恢复控制信道资源。
规则二：所述F个控制信道资源中的不同控制信道资源的关联一类准共址参数的准共址参考信号不满足准共址关系，即所述F个控制信道资源中关联一类准共址参数的准共址参考信号不满足准共址关系，比如H个控制信道资源中两个控制信道资源关联所述一类准共址参数的准共址参考信号满足准共址关系，则视为一个控制信道资源，只选择这两个控制信道资源其中一个控制信道资源就可以。
规则三：所述F个控制信道资源是专有控制信道资源，即公共控制信道资源不包括在所述F个控制信道资源中。
规则四：所述F个控制信道资源是所述H个控制信道资源中最新配置的控制信道资源。
规则五：所述F个控制信道资源关联一类准共址参数的准共址参考信号是所述H个控制信道资源关联所述一类准共址参数的准共址参考信号构成的集合中带宽最大的F个准共址参考信号和密度最大的F个准共址参考信号中至少之一。
规则六：所述H个控制信道资源关联所述一类准共址参数的准共址参考信号集合中包括的SSB(SS/PBCH Block：Synchronization Signal and PBCH Block，同步信号/物理广播信道块)控制信道资源优先选为所述F个控制信道资源。
规则七：所述F个控制信道资源配置了关联一类准共址参数的准共址参考信号。
规则八：所述F个控制信道资源的控制信道资源索引在一个控制信道资源 集合中满足预定特征，比如为一个控制信道资源集合中最低F个控制信道资源索引对应的控制信道资源(当然也可以是一个控制信道资源集合中最高F个控制信道资源索引对应的控制信道资源，或者一个控制信道资源集合中满足其他预定特征的控制信道资源)，所述一个控制信道资源集合为一个BWP或者一个CC中配置的控制信道资源构成的集合，或者为一个BWP或者一个CC中配置的控制信道资源中满足预定特征的控制信道资源构成的集合，比如为满足上述规则一至七中任意一个或者多个的控制信道资源构成的集合。
上述控制信道资源是CORESET，当然如果可以搜索空间级别/每个搜索空间集合级别配置准共址参考信号时，上述一个控制信道资源也可以是一个搜索空间或者一个搜索空间集合。
在本场景下，所述一类准共址参数包括空间接收参数。
在本文中，所述一个频域带宽为一个频域带宽部分或者一个成员载波对应的频域带宽。
场景8
图20是根据本发明实施例的发送接收节点(Transmission Reception Point，TRP)的交互示意图。
如图20所示，有两个TRP给一个终端服务，当然也可以是多于两个的TRP给终端服务。特别是这两个TRP中没有理想回程线路(Backhaul)，从而两个TRP到终端(User Equipment，UE)的通信相对独立进行，比如TRP1发送DCI1调度PDSCH1/PUSCH1，TRP2发送DCI2调度PDSCH2/PUSCH2，两个TRP之间交互信息需要考虑时延。
为此可以让CORESET组i/SS(搜索空间)组i/CC组i对应TRPi，i＝0,1，当终端检测到一个TRP对应的波束失败检测参考信号集合中的参考信号发生波束 失败事件时，就应该告知基站(包括TRP1和TRP2中至少一个)，而不是等到两个TRP的PDCCH都无法到达终端时，才认为发生波束失败事件。
如图20所示，每个TRP对应一套波束失败恢复参数，即比如每个CORESET组/SS(搜索空间)组/CC组/CC/BWP/TRP对应一套波束失败恢复参数，其中波束失败恢复参数包括如下参数至少之一：波束失败检测参考信号集合(即所述波束失败检测参考信号集合i，i＝0,1)、候选参考信号集合(即所述候选参考信号集合i，i＝0,1)、波束失败检测计数器(即所述波束失败检测计数器i，i＝0,1)、参考信号指示信息发送次数计数器(即所述参考信号指示信息发送次数计数器i，i＝0,1)、波束失败检测计时器(即所述波束失败检测计时器i，i＝0,1)、波束失败恢复计时器(即所述波束失败恢复计时器i，i＝0,1)、监听计时器(即所述监听计时器i，i＝0,1)、参考信号指示信息上报资源(即所述PRACH-BFRi，i＝0,1)、波束失败恢复控制信道资源(即所述SS-BFRi，i＝0,1)。
图20中是每个CORESET组/SS(搜索空间)组/CC组/TRP都对应一套独立的波束失败恢复参数，即分别对应一个独立的波束失败恢复过程，本场景中的第二种实施方式中，每个CORESET组/SS(搜索空间)组/CC组/TRP的部分波束失败恢复参数是独立的，部分失败恢复参数是共享的，比如有两套波束失败检测参考信号集合(比如波束失败检测参考信号集合i，i＝0,1)、两套候选参考信号集合(比如候选参考信号集合i，i＝0,1)，只要任意一个波束失败检测参考信号集合检测到波束失败事件，就在该波束失败检测参考信号集合对应的候选参考信号集合中选择新参考信号，两套候选参考信号集合中的每个参考信号在PRACH-BFR中都有PRACH资源与其对应。进一步可以限定一个时间单元中只上报一套候选参考信号集合中选择的参考指示信息。上述两个TRP独立对应的波束失败恢复参数包括波束失败检测参考信号集合和候选参考信号集合，当然 本实施例也不排除两个TRP独立对应的波束失败恢复参数包括的是其他波束失败恢复参数，SS-BFR的DCI中(或者SS-BFR中的DCI调度的PDSCH中)需要指示候选参考信号集合套数索引信息，用于指示基站在该SS-BFR中的发送PDCCH是因为基站收到了哪个候选参考信号集合(候选参考信号集合0还是候选参考信号集合1)，或者不同候选参考信号集合{候选参考信号集合0，候选参考信号集合1}对应SS-BFR中的PDCCH的不同时间段/不同RNTI(Radio Network Tempory Identity，无线网络临时标识)加扰序列/不同解调参考信号序列。
本场景中的第三种实施方式中，两个TRP分别对应两套波束失败检测参考信号集合(比如波束失败检测参考信号集合i，i＝0,1)、两套候选参考信号集合(比如候选参考信号集合i，i＝0,1)中的一套，PRACH-BFR只和一套候选参考信号集合中的参考信号建立关联，比如和候选参考信号集合0建立关联。当终端通过检测波束失败检测参考信号集合1中参考信号发现波束失败事件发生时，终端可以通过发送给TRP0的SR/MAC-CE命令中告知TRP0如下信息至少之一：TRP1对应的波束失败检测参考信号集合1发生了波束失败事件、终端在候选参考信号集合1中选择的参考信号指示信息、TRP0将上述信息转发给TRP1。
场景9
在本实施例中，除了有针对SPcell的波束失败恢复过程，也有针对Scell(Secondary Cell，辅小区)的波束失败过程，从而检测Scell的波束运行状况。为此可以有如下方案：
方案一：Pcell/SPcell与Scell分别对应一套独立的波束失败恢复参数，各自对应图11中的一个波束失败恢复过程。
方案二：Pcell/SPcell与Scell分别对应的一套部分波束失败恢复参数，其他波束失败恢复参数是Pcell/SPcell与Scell共享的，比如Pcell/SPcell对应{波束失败检测参考信号集合0，候选参考信号集合0}，Scell对应{波束失败检测参考信号集合1，候选参考信号集合1}。通过一个波束失败检测参考信号集合中的参考信号检测到波束失败事件时，在与这个波束失败检测参考信号集合对应的候选参考信号集合中选择参考信号。PRACH-BFR和SS-BFR中至少之一只在Pcell/SPcell中，比如两套候选参考信号集合{候选参考信号集合0，候选参考信号集合1}中的每个参考信号在Pcell/SPcell中的PRACH-BFR中至少有一个PRACH资源与其关联，从而PRACH-BFR资源关联的候选参考信号的配置信息中需要携带CC信息。
方案三：Pcell/SPcell对应同一个波束失败恢复过程，只是在波束失败检测参考信号集合中可以包括Pcell中的参考信号。
在本实施例中，所述频域带宽包括频域带宽部分和成员载波(Component Carrior，CC)中至少一个，即一个频域带宽包括一个频域带宽部分和一个成员载波对应的频域带宽中至少一个，频域带宽索引包括频域带宽部分BWP索引和CC索引中至少一个。
