Description

下行无线链路质量的评估方法及装置 技术领域
本申请涉及通信领域。
背景技术
在RRC连接(RRC_CONNECTED)中，基于参考信号(例如同步信号和PBCH块SSB或信道状态信息参考信号CSI-RS)和网络配置的参考信号阈值，终端设备在激活的BWP(Bandwidth Part)里执行无线链路监听(Radio Link Monitoring，RLM)。
无线链路监听适用于SA NR、NR-DC和NE-DC操作模式下的主小区(PCell)和NR-DC和EN-DC操作模式下的主辅小区(PSCell)。
基于SSB的RLM基于初始下行BWP(DL BWP)关联的SSB，且仅能为初始DL BWP和包括初始DL BWP关联的SSB的DL BWPs配置。对于其他DL BWPs，RLM仅基于CSI-RS执行。不要求终端设备在激活DL BWP之外执行RLM。
在双激活协议栈(Dual Active Protocol Stack，DAPS)切换的情况下，终端设备继续源小区上的无线链路失败(RLF)检测，直到在目标小区成功完成随机接入过程。
另外，对于波束失败检测(Beam Failure Detection，BFD)过程，终端设备将会基于参考信号评估一个服务小区的下行无线链路质量，以检测波束失败。这适用于SA、NR-DC和NE-DC操作模式下的PCell，NR-DC和EN-DC操作模式下的PSCell，和SA、NR-DC，NE-DC或EN-DC操作模式下的SCell。不要求终端设备在一个去激活的SCell上执行波束失败检测，也不要求在隐式配置给一个去激活SCell的资源上执行波束失败检测。
基于SSB的波束失败检测基于初始DL BWP关联的SSB，且仅能配置给初始DL BWPs和包括初始DL BWP关联的SSB的DL BWPs。对于其他DL BWPs，波束失败检测仅基于CSI-RS执行。不要求终端设备在激活DL BWP之外执行波束失败检测。
通过计算低层到MAC实体的波束失败实例(instance)指示的数量，检测波束失败。
对于RRC_CONNECTED下的物理层问题的检测，终端设备将会：

无线链路失败的检测，包括终端设备将会：

2>一旦MCG MAC指示持续上行LBT失败同时T304未运行：
3>如果这个指示来自MCG RLC且配置了CA duplication且对MCG激活，且对于相应的逻辑信道，allowedServingCells仅包括辅小区：

6>发起MCG失败信息过程以上报MCG无线链路失败
5>否则：

波束失败检测过程使用终端设备(UE)变量BFI_COUNTER，这个变量是波束失败实例指示的计数器，初始设置为0，每个服务小区有一个。
图1是服务小区波束失败的检测或波束失败恢复的触发的一流程图。如图1所示，
对于每个配置了波束失败检测的服务小区，MAC实体将会：
如果从低层收到了波束失败实例指示：
启动或重启beamFailureDetectionTimer；
BFI_COUNTER加1；
如果BFI_COUNTER大于或等于beamFailureInstanceMaxCount：
如果服务小区是辅小区(SCell)，触发这个服务小区的一个BFR；
否则，在这个特殊小区(SpCell)上发起随机接入过程。
如果beamFailureDetectionTimer超时；或
如果高层重配了这个服务小区的beamFailureDetectionTimer，beamFailureInstanceMaxCount或用于波束失败检测的任何参考信号：
设置BFI_COUNTER为0。
这个过程适用于Rel-15和Rel-16的特殊小区和辅小区。
MAC实体可以被RRC每服务小区配置波束失败恢复过程，这个过程用于当在服务SSB(s)或CSI-RS(s)上检测到波束失败时，向服务网络设备指示一个新的SSB或CSI-RS。
应该注意，上面对技术背景的介绍只是为了方便，对本发明的技术方案进行清楚、完整的说明，并方便本领域技术人员的理解而阐述的。不能仅仅因为这些方案在本发 明的背景技术部分进行了阐述而认为上述技术方案为本领域技术人员所公知。
发明内容
第一方面，对于多TRP(发送接收点，Transmission Reception Point)操作下的波束失败检测，网络设备为终端设备配置2组波束失败检测参考信号，每组关联一个TRP，在配置的定时器超时前，当来自物理层的波束失败检测参考信号相应组关联的波束失败实施例指示数达到一个配置的阈值时，终端设备宣布这个TRP的波束失败。
检测到服务小区的一个TRP的波束失败后，终端设备：
- 通过发起这个TRP的BFR MAC CE的传输，触发波束失败恢复；
- 为这个TRP选择一个合适的波束(如果可用)并在这个TRP的这个BFR MAC CE里指示是否找到合适的(新)波束以及波束失败的信息。
当收到指示用于一个TRP的BFR MAC CE的传输的HARQ进程的一个新传的上行授权的PDCCH时，认为这个TRP的波束失败恢复完成。
检测到特殊小区的两个TRPs的波束失败后，终端设备：
- 通过发起特殊小区上的随机接入过程，触发波束失败恢复；
- 为每个失败的TRP选择一个合适的波束(如果可用)并在每个失败的TRP的BFR MAC CE里指示是否找到合适的(新)波束以及波束失败的信息；
- 当完成随机接入过程时，认为特殊小区的两个TRPs波束失败恢复完成。
具体的，
针对TRP特定的波束失败恢复的触发，RRC配置了一些参数，例如：
- 配置了2个BFD-RS组的服务小区的每BFD-RS组的波束失败检测的beamFailureInstanceMaxCount
- 配置了2个BFD-RS组的服务小区的每BFD-RS组的波束失败检测的beamFailureDetectionTimer
以下UE变量用于波束失败检测过程：
- BFI_COUNTER(配置了2个BFD-RS组的服务小区的每BFD-RS组)：波束失败实施例指示的计数器，其初始设置为0
对于每个配置了波束失败检测的服务小区，MAC实体将会：
1>如果这个服务小区被配置了两个BFD-RS组，对于这个服务小区的每个BFD-RS组，MAC实体将会：
2>如果从低层收到了一个BFD-RS组的波束失败实例指示：
3>启动或重启beamFailureDetectionTimer；
3>这个BFD-RS组的BFI_COUNTER加1；
3>如果BFI_COUNTER大于或等于beamFailureInstanceMaxCount：
4>触发这个服务小区的这个BFD-RS组的BFR；
2>如果这个特殊小区的两个BFD-RS组都触发了BFR且尚未成功完成：
3>在这个特殊小区上发起随机接入过程；
2>如果这个服务小区是特殊小区且为这个特殊小区的两个BFD-RS组的波束失败恢复发起的随机接入过程成功完成：
3>设置特殊小区的每个BFD-RS组的BFI_COUNTER为0；
3>认为这个波束失败恢复过程成功完成。
2>如果这个BFD-RS组的beamFailureDetectionTimer超时；或
2>如果高层重配了这个服务小区这个BFD-RS组的beamFailureDetectionTimer，beamFailureInstanceMaxCount或用于波束失败检测的任何参考信号：
3>设置这个BFD-RS组的BFI_COUNTER为0。
2>如果收到一个C-RNTI寻址的PDCCH，指示用于传输包括这个服务小区的这个BFD-RS组的波束失败恢复信息的Enhanced BFR MAC CE或Truncated Enhanced BFR MAC CE的HARQ进程的一个新传的上行授权：
3>设置这个BFD-RS组的BFI_COUNTER为0；
3>认为这个波束失败恢复过程成功完成并取消这个服务小区这个BFD-RS组所有触发的BFRs。
2>如果这个服务小区是辅小区，且这个辅小区去激活：
3>设置辅小区的每个BFD-RS组的BFI_COUNTER为0；
3>认为这个波束失败恢复过程成功完成并取消这个服务小区所有BFD-RS组所有触发的BFRs。
第二方面，对于多RAT双连接的进一步增强，在Rel-16里，3GPP已经了NR和LTE的移动性增强，以减少切换期间数据传输中断，并改善切换健壮性。在Rel-16里，3GPP已经引入一些增强以提高高效的MR-DC配置并改善MR-DC性能，例如 通过早期的测量上报、通过SCG的快速MCG失败恢复。
在EN-DC里，由于同时维持2个无线链路，终端设备和网络能耗是一个大问题。在一些情况下，NR UE能耗比LTE高3到4倍。在EN-DC部署里，MN提供基本覆盖。当终端设备数据速率的需求动态变化时，如从高到低，(去)激活SN以节省网络和终端设备能耗，是值得考虑的。因此，在Rel-17里，应该定义一种高效的SCG(去)激活机制，这种机制也适用于其他MR-DC操作，例如NGEN-DC和NR-DC。
发明人发现，基于现有技术和上面的第一点，为了检测无线链路失败和/或波束失败，要求终端设备：
- 对用于无线链路失败检测的参考信号进行无线链路质量的监听，以向高层(RRC)提供“in-sync”指示或“out-of-sync”指示；
- 评估用于波束失败检测的参考信号的无线链路质量，以向高层(MAC)提供波束失败实施例指示，其中用于波束失败检测的参考信号可以是：为一个特殊小区或一个激活的SCell的一个激活DL BWP配置的；或为一个小区的一个TRP配置的。
基于上面的第二点，Rel-17支持SCG激活和去激活机制，其中SCG的特殊小区PSCell可以被去激活。当SCG被去激活时，PSCell和SCG的所有SCell被去激活，如果网络配置，终端设备在PSCell上执行RLM和波束失败检测。SCG去激活期间，对于PSCell波束失败，当PSCell波束失败时，终端设备停止波束失败检测；当重配置BFD-RS时，恢复波束失败检测。当收到网络SCG激活命令时，如果宣布了RLF或波束失败，终端设备将会向SCG执行随机接入过程。
发明人发现，对于现有技术，存在以下问题：
如果仅支持SCG去激活下小区级的波束失败检测：PSCell可能未配置用于小区波束失败检测的参考信号，而是配置了用于TRP特定的波束失败检测的参考信号，在这种情况下，当SCG去激活时，即便网络配置终端设备进行波束失败检测，终端设备无法进行小区级的波束失败检测，从而无法评估波束质量，使得终端设备使用无线链路质量差的波束进行通信，降低通信质量；
如果支持SCG去激活下小区级/TRP特定的波束失败检测：按照现有机制，当波束失败时，终端设备停止波束失败检测，且在SCG去激活时向SCG发起随机接入过程。如果波束失败仅发生在PSCell的一个TRP，另外一个TRP仍能使用，那么SCG去激活时的随机接入过程是不必要的，导致增加能耗，降低用户体验。

在本申请实施例中，术语“通信网络”或“无线通信网络”可以指符合如下任意通信标准的网络，例如长期演进(LTE，Long Term Evolution)、增强的长期演进(LTE-A，LTE-Advanced)、宽带码分多址接入(WCDMA，Wideband Code Division Multiple Access)、高速报文接入(HSPA，High-Speed Packet Access)等等。
并且，通信系统中设备之间的通信可以根据任意阶段的通信协议进行，例如可以包括但不限于如下通信协议：1G(generation)、2G、2.5G、2.75G、3G、4G、4.5G以及未来的5G、新无线(NR，New Radio)等等，和/或其他目前已知或未来将被开发的通信协议。
在本申请实施例中，术语“网络设备”例如是指通信系统中将用户设备接入通信网络并为该用户设备提供服务的设备。网络设备可以包括但不限于如下设备：IAB架构下的“节点(node)”和/或“宿主(donor)”、基站(BS，Base Station)、接入点(AP、Access Point)、发送接收点(TRP，Transmission Reception Point)、广播发射机、移动管理实体(MME、Mobile Management Entity)、网关、服务器、无线网络控制器(RNC，Radio Network Controller)、基站控制器(BSC，Base Station Controller)等等。
其中，基站可以包括但不限于：节点B(NodeB或NB)、演进节点B(eNodeB或eNB)以及5G基站(gNB)，等等，此外还可包括远端无线头(RRH，Remote Radio Head)、远端无线单元(RRU，Remote Radio Unit)、中继(relay)或者低功率节点(例如femto、pico等等)。并且术语“基站”可以包括它们的一些或所有功能，每个基站可以对特定的地理区域提供通信覆盖，例如5G基站gNB可以包括一个gNB CU和一个或多个gNB DU，其中CU/DU是具有gNB部分功能的gNB的一个逻辑节点。术语“小区”可以指的是基站和/或其覆盖区域，这取决于使用该术语的上下文。一个gNB-DU支持一个或多个小区，一个小区仅由一个gNB-DU支持。

在本申请实施例中，“当……时”、“在……情况下”、“对于……的情况”以及“如果……”都表示基于某个或某些条件或状态等，另外，这些表述方式可以互相替换。
以下通过示例对本申请实施例的场景进行说明，但本发明不限于此。
图2是本申请实施例的通信系统的一示意图，其示意性说明了以终端设备和网络设备为例的情况，如图2所示，通信系统100可以包括：网络设备101和终端设备102。为简单起见，图1仅以一个终端设备为例进行说明。网络设备101例如为NR的网络设备gNB。
在本申请实施例中，网络设备101和终端设备102之间可以进行现有的业务或者未来可实施的业务。例如，这些业务包括但不限于：增强的移动宽带(eMBB，enhanced Mobile Broadband)、大规模机器类型通信(mMTC，massive Machine Type Communication)和高可靠低时延通信(URLLC，Ultra-Reliable and Low-Latency Communication)，等等。
例如，对于多TRP(mTRP)的场景，网络设备通过TRP-1和TRP-2为终端设备102提供服务。
在本申请实施例中，TRP是从终端设备接收信号和/或向终端设备发送信号的网络设备的一部分。在多TRP(mTRP)操作里，一个服务小区可以从两个TRP调度终 端设备，提供更好的PDSCH覆盖、可靠性和/或数据速率，这两个TRP可以属于同一小区。对于多TRP，有两种不同的操作模式，即单DCI(下行链路控制信息，Downlink Control Information)和多DCI。对于这两种模式，在RRC层提供的配置内，上行和下行操作的控制由物理层和MAC层进行。在单DCI模式下，终端设备由两个TRP通过相同的DCI调度；在多DCI模式下，终端设备由每个TRP的单独的DCI调度。
图3是本申请实施例的多TRP的场景的一示意图。如图3所示，网络设备101部署了两个TRP，即TRP1和TRP2。网络设备101通过TRP1和TRP2与终端设备102进行工作，例如，TRP1和TRP2属于PSCell。即便波束失败仅发生在TRP1，而TRP2仍能使用，按照现有机制，在SCG去激活时，终端设备102也会停止对TRP1和TRP2的波束失败检测，这使得终端设备102无法评估PSCell的波束质量；并且在SCG被激活时，终端设备102将向网络设备101发起随机接入过程。这导致网络和终端增加能耗，并且降低了用户体验。
下面结合附图对本申请实施例的各种实施方式进行说明。这些实施方式只是示例性的，不是对本发明的限制。
实施例1
本申请实施例提供了一种下行无线链路质量的评估方法，该方法应用于终端设备。例如，该方法应用于图2和图3中的终端设备102。
图4是本申请实施例1的下行无线链路质量的评估方法的一示意图。如图4所示，该方法包括：
步骤401：配置了辅小区组(SCG)；
步骤402：在网络指示该辅小区组支持无线链路监听(RLM)的情况下，当该辅小区组被去激活时，在主辅小区(PSCell)上执行无线链路监听；和/或，
步骤403：在网络指示该辅小区组支持波束失败检测的情况下，并且，在为该主辅小区配置了用于小区的波束失败检测的参考信号的情况下，当该辅小区组被去激活时，执行该主辅小区的波束失败检测；和/或，
步骤404：在网络指示该辅小区组支持波束失败检测的情况下，并且，在为该主辅小区配置了用于TRP特定的波束失败检测的参考信号的情况下，当该辅小区组被去激活时，执行该主辅小区的TRP特定的波束失败检测。
在本申请实施例中，在步骤401之后，该方法可以包括步骤402-404中的至少一 个步骤，并且，在包括步骤402-404中的多个步骤时，不对这些步骤之间的执行顺序进行限制。
这样，在网络指示SCG支持波束失败检测的情况下，并且，在为PSCell配置了用于小区的波束失败检测的参考信号的情况下，当该SCG被去激活时，执行该PSCell的波束失败检测，因此，当该SCG被去激活时，终端设备能够进行小区级的波束失败检测，从而评估波束质量，使得终端设备能够使用无线链路质量较好的波束进行通信，保证通信质量；
另外，在网络指示该SCG支持波束失败检测的情况下，并且，在为PSCell配置了用于TRP特定的波束失败检测的参考信号的情况下，当该SCG被去激活时，执行该PSCell的TRP特定的波束失败检测，因此，在波束失败仅发生在PSCell的一个TRP，另外一个TRP仍能使用的情况下，当该SCG被去激活时，终端设备不会停止波束失败检测以及发起随机接入过程，从而能够避免能耗的增加，提升用户体验。
在一些实施例中，“TRP特定的”可以替换为“BFD-RS组的”或“BFD-RS组关联的”。
在一些实施例中，“波束失败”可以替换为“波束失败恢复”或“触发了波束失败恢复”。
在步骤401中，配置了辅小区组(SCG)是指终端设备配置了辅小区组。
在一些实施例中，该主辅小区是终端设备配置了的辅小区组的主辅小区。
在一些实施例中，指示支持或是否支持无线链路监听(RLM)和/或波束失败检测的该配置可以包括在小区组配置(CellGroupConfig)IE里。
在一些实施例中，网络可以通过共用的配置或单独的配置指示支持该辅小区组去激活时的无线链路监听或是否支持该辅小区组去激活时的无线链路监听，和/或，指示支持该辅小区组去激活时的波束失败检测或是否支持该辅小区组去激活时的波束失败检测。例如，该共用的配置或单独的配置可以包括在小区组配置(CellGroupConfig)IE里。
在一些实施例中，该共用的配置用于配置SCG去激活时，指示终端设备执行无线链路监听和/或波束失败检测，或指示终端设备是否执行无线链路监听和/或波束失败检测，该波束失败检测包括小区的波束失败检测或TRP特定的波束失败检测。
在一些实施例中，该共用的配置可以是布尔型(BOOLEAN)数据或枚举型 (ENUMERATED)数据。
在一些实施例中，在该共用的配置是布尔型(BOOLEAN)数据的情况下，如果值为“true”，表示当SCG被去激活时，终端设备执行无线链路监听和/或波束失败检测，如果值为“false”，表示当SCG被去激活时，终端设备不/停止执行无线链路监听和/或波束失败检测。在该情况下，该共用的配置的域是强制的(mandatory)域。
例如，在该共用的配置是布尔型(BOOLEAN)数据的情况下，该共用的配置用于配置SCG去激活时，指示终端设备是否执行无线链路监听和/或波束失败检测，该波束失败检测包括小区的波束失败检测或TRP特定的波束失败检测。
在一些实施例中，在该共用的配置是枚举型(ENUMERATED)数据的情况下，其值为“true”。也就是说，如果配置了这个域，表示当SCG被去激活时，终端设备执行无线链路监听和/或波束失败检测；在该情况下，该共用的配置的域是可选的(optional)域，而不是必需的。
例如，在该共用的配置是枚举型(ENUMERATED)数据的情况下，该共用的配置用于配置SCG去激活时，指示终端设备执行无线链路监听和/或波束失败检测，该波束失败检测包括小区的波束失败检测或TRP特定的波束失败检测。
在一些实施例中，该单独的配置包括以下中的至少一个：
用于配置该辅小区组去激活时，指示终端设备是否执行主辅小区上的无线链路监听和小区的波束失败检测，或指示终端设备执行主辅小区上的无线链路监听和小区的波束失败检测；
用于配置该辅小区组去激活时，指示终端设备是否执行主辅小区上的无线链路监听，或指示终端设备执行主辅小区上的无线链路监听；
用于配置该辅小区组去激活时，指示终端设备是否执行主辅小区上小区的或TRP特定的波束失败检测，或指示终端设备执行主辅小区上小区的或TRP特定的波束失败检测；
用于配置该辅小区组去激活时，指示终端设备是否执行主辅小区上小区的波束失败检测，或指示终端设备执行主辅小区上小区的波束失败检测；以及
用于配置该辅小区组去激活时，指示终端设备是否执行主辅小区上TRP特定的波束失败检测，或指示终端设备执行主辅小区上TRP特定的波束失败检测。
在一些实施例中，该单独的配置可以是布尔型(BOOLEAN)数据或枚举型 (ENUMERATED)数据。
在一些实施例中，在该单独的配置是布尔型(BOOLEAN)数据的情况下，如果值为“true”，表示当SCG被去激活时，终端设备执行无线链路监听和/或波束失败检测，如果值为“false”，表示当SCG被去激活时，终端设备不执行无线链路监听和/或波束失败检测。在该情况下，该单独的配置的域是强制的(mandatory)域。
例如，在该单独的配置是布尔型(BOOLEAN)数据的情况下，
该单独的配置包括以下中的至少一个：用于配置该辅小区组去激活时，指示终端设备是否执行主辅小区上的无线链路监听和小区的波束失败检测；用于配置该辅小区组去激活时，指示终端设备是否执行主辅小区上的无线链路监听；用于配置该辅小区组去激活时，指示终端设备是否执行主辅小区上小区的或TRP特定的波束失败检测；用于配置该辅小区组去激活时，指示终端设备是否执行主辅小区上小区的波束失败检测；以及用于配置该辅小区组去激活时，指示终端设备是否执行主辅小区上TRP特定的波束失败检测。
在一些实施例中，在该单独的配置是枚举型(ENUMERATED)数据的情况下，其值为“true”。也就是说，如果配置了这个域，表示当SCG被去激活时，终端设备执行无线链路监听和/或波束失败检测；在该情况下，该单独的配置的域是可选的(optional)域，而不是必需的。
例如，在该单独的配置是枚举型(ENUMERATED)数据的情况下，
该单独的配置包括以下中的至少一个：用于配置该辅小区组去激活时，指示终端设备执行主辅小区上的无线链路监听和小区的波束失败检测；用于配置该辅小区组去激活时，指示终端设备执行主辅小区上的无线链路监听；用于配置该辅小区组去激活时，指示终端设备执行主辅小区上小区的或TRP特定的波束失败检测；用于配置该辅小区组去激活时，指示终端设备执行主辅小区上小区的波束失败检测；以及用于配置该辅小区组去激活时，指示终端设备执行主辅小区上TRP特定的波束失败检测。
在一些实施例中，对于配置的该辅小区组，当上层指示该辅小区组的激活时，MAC实体将会应用以下至少之一的辅小区组激活操作：激活主辅小区；主辅小区上的SRS传输；主辅小区上的CSI上报；主辅小区上的PDCCH监听；主辅小区上的PUCCH传输；如果触发，执行主辅小区上的随机接入；以及初始化主辅小区关联的每个逻辑信道的Bj为0。
在一些实施例中，对于配置的该辅小区组，当上层指示该辅小区组被去激活时，MAC实体将会执行以下至少之一：去激活配置的该辅小区组所有的辅小区(SCells)；去激活主辅小区；以及重置MAC。
在一些实施例中，该重置MAC可以包括以下至少之一：停止第一定时器以外的其他所有正在运行的定时器或停止正在运行的所有定时器；停止正在进行的随机接入过程；清空Msg3缓存(buffer)；清空MSGA缓存(buffer)；取消触发的波束失败恢复(BFR)；以及重置第一计数器。
在步骤402中，在网络指示该辅小区组支持无线链路监听(RLM)的情况下，当该辅小区组被去激活时，在主辅小区(PSCell)上执行无线链路监听。
在一些实施例中，在主辅小区(PSCell)上执行无线链路监听，可以包括：在网络配置了在去激活的主辅小区上执行无线链路监听的情况下，终端设备在激活DL BWP之外的BWP上执行无线链路监听。也就是说，不要求终端设备在在激活DL BWP之外的BWP上执行无线链路监听，除非网络配置了在去激活的主辅小区上执行无线链路监听。
例如，在网络配置了在去激活的主辅小区上执行无线链路监听且未检测到该主辅小区或该主辅小区所在辅小区组的无线链路失败的情况下，终端设备在激活DL BWP之外的BWP上执行无线链路监听。
在步骤403中，
在一些实施例中，停止第一定时器以外的其他所有正在运行的定时器或停止正在运行的所有定时器，可以包括：
在网络指示该辅小区组支持无线链路监听和/或波束失败检测，且为该辅小区组的主辅小区配置了用于小区的波束失败检测的参考信号的情况下，停止第一定时器以外的其他所有正在运行的定时器，该第一定时器包括TA定时器(例如TA timer)和该主辅小区关联的波束失败检测定时器(例如beamFailureDetectionTimer)。
在一些实施例中，TRP特定的波束失败检测定时器也可以替换为：BFD-RS组关联的波束失败检测定时器。
在一些实施例中，配置了用于TRP特定的波束失败检测的参考信号也可以替换为：配置了多个(例如2个)BFD-RS组。
在一些实施例中，取消触发的波束失败恢复(BFR)可以包括以下至少之一：取 消主辅小区触发的波束失败恢复；取消主辅小区的一个BFD-RS组触发的波束失败恢复。
例如，在网络指示该辅小区组支持无线链路监听和/或波束失败检测，且为该辅小区组的主辅小区配置了用于TRP特定的波束失败检测的参考信号的情况下，停止该主辅小区的一个BFD-RS组的波束失败检测。
在一些实施例中，第一计数器可以是波束失败指示的计数器，例如BFI_COUNTER。

和/或，处理器2310可以被配置为：为终端设备配置了辅小区组(SCG)；其中，在未指示该辅小区组或该辅小区组的辅小区(SCell)支持无线链路监听(RLM)的情况下，当该辅小区组被去激活时，该终端设备停止该辅小区上的无线链路监听；和/或，在未指示该辅小区组或该辅小区组的辅小区支持波束失败检测，或者，未为该辅小区配置用于小区的波束失败检测的参考信号的情况下，当该辅小区组被去激活时，该终端设备停止该辅小区上的波束失败检测；和/或，在未指示该辅小区组或该辅小区组的辅小区支持波束失败检测，或者，未为该辅小区配置用于TRP特定的波束失败检测的参考信号的情况下，当该辅小区组被去激活时，该终端设备停止该辅小区上的TRP特定的波束失败检测。
在另一个实施方式中，下行无线链路质量的评估装置可以与处理器2310分开配置，例如可以将下行无线链路质量的评估装置配置为与处理器2310连接的芯片，通过处理器2310的控制来实现下行无线链路质量的评估装置的功能。
此外，如图23所示，网络设备2300还可以包括：收发机2340和天线2350等；其中，上述部件的功能与现有技术类似，此处不再赘述。值得注意的是，网络设备2300也并不是必须要包括图23中所示的所有部件；此外，网络设备2300还可以包括图23中没有示出的部件，可以参考现有技术。
由上述实施例可知，在网络指示SCG支持波束失败检测的情况下，并且，在为PSCell配置了用于小区的波束失败检测的参考信号的情况下，当该SCG被去激活时，执行该PSCell的波束失败检测，因此，当该SCG被去激活时，终端设备能够进行小区级的波束失败检测，从而评估波束质量，使得终端设备能够使用无线链路质量较好的波束进行通信，保证通信质量；
另外，在网络指示该SCG支持波束失败检测的情况下，并且，在为PSCell配置了用于TRP特定的波束失败检测的参考信号的情况下，当该SCG被去激活时，执行该PSCell的TRP特定的波束失败检测，因此，在波束失败仅发生在PSCell的一个TRP，另外一个TRP仍能使用的情况下，当该SCG被去激活时，终端设备不会停止波束失败检测以及发起随机接入过程，从而能够避免能耗的增加，提升用户体验；
另外，在网络指示该SCG支持辅小区的无线链路监听和/或波束失败检测的情况下，当该SCG被去激活时，执行该辅小区的无线链路监听和/或波束失败检测，因此，当该SCG被去激活时，终端设备能进行辅小区的无线链路监听和/或波束失败检测，从而评估无线链路和/或波束质量，使得终端设备能够使用质量较好的无线链路和/或波束进行通信，保证通信质量。
