具体实施方式
下面结合附图和实施例对本申请的实施方式作进一步详细描述。以下 实施例的详细描述和附图用于示例性地说明本申请的原理，但不能用来限制本申请的范围，即本申请不限于所描述的实施例。
以下结合附图，详细说明本申请各实施例提供的技术方案。
参见图1所示，本申请实施例提供一种链路管理方法，由终端设备执行，该方法可以包括以下内容：
步骤101：接收传输配置指示TCI信息，TCI信息用于指示唤醒信号WUS的M个TCI状态，M为正整数。
可以理解，M的取值为大于或等于1的整数。
步骤103：在处于连接态非连续接收DRX的睡眠期的情况下，基于M个TCI状态，执行链路管理操作，链路管理操作包括波束失败监测操作和无线链路失败监测操作中的至少一个。
该实施例，在网络设备配置了用于指示唤醒信号WUS的至少一个TCI状态的传输配置指示TCI信息的情况下，处于连接态非连续接收DRX的睡眠期的终端设备，在基于该M个TCI状态执行相应的链路管理操作时，至少可以执行波束失败监测和无线链路失败监测中的一个操作。如此，可以解决现有方案中在连接态DXR的睡眠期终端设备无法进行波束失败或无线链路失败监测的问题，从而使得波束失败监测和无线链路失败监测不受WUS解码结果和连接态下DRX配置情况的影响，保证对链路状态的跟踪性能，即能够及时且准确地监测到波束失败和/或无线链路失败的情况，并能够降低终端设备的功耗。进一步地，由于可以及时且准确地监测到波束失败和/或无线链路失败的情况，有助于终端设备在DRX的激活期即将醒来时，提前进行波束恢复或无线链路重建的相关准备，比如提前确定满足波束恢复条件的波束，以避免终端设备醒来进入DRX的激活期后由于确定用于波束恢复或无线链路重建的资源的时延，影响数据接收的效率。
可以理解，对于终端设备来说，在M个TCI状态为多个时，网络设备基于M个TCI状态中的任意两个TCI状态发送的WUS相同，即在对WUS解码成功的情况下其指示终端设备保持在DRX的睡眠期或从DRX的睡眠期进入DRX的激活期的解码结果是相同的，也就是说，终端设备 认为网络设备基于M个TCI状态发送的所有WUS所携带的醒或睡的消息是一致的。同时，借助多个TCI状态可以提高WUS的接收可靠性。
可选的，在本申请实施例的链路管理方法中，对于上述M个TCI状态，可以具有不同的配置方案，使得终端设备基于M个TCI状态对应的波束检测WUS的方案具备多样性。
在一个具体实施例中，上述M个TCI状态中任意两个TCI状态对应的控制资源集(Control Resource Set，CORESET)配置和搜索空间(Search Space，SS)配置相同、时隙相关配置不同。
可以理解，在M个TCI状态为多个的情况下，多个TCI状态中的任意两个TCI状态可以具有相同的CORESET配置和相同的SS配置，但该多个TCI状态中的每个TCI状态可以具有专属的时隙相关配置，即任意两个TCI状态之间的时隙相关配置不同。也就是说，一个CORESET上有一个SS，该SS配置多个不同的时隙相关配置，一个时隙相关配置与一个TCI状态对应。
在另一个具体实施例中，上述M个TCI状态中任意两个TCI状态对应的CORESET配置相同、SS配置不同，每个SS配置有独立的时隙相关配置。
可以理解，在M个TCI状态为多个的情况下，多个TCI状态中的任意两个TCI状态可以具有相同的CORESET配置和不同的SS配置，具体该M个TCI状态对应的M个SS配置中的每个SS配置可以具有独立专属的时隙相关配置。也就是说，一个CORESET上有多个SS，每个SS对应配置一个时隙相关配置，一个时隙相关配置与一个TCI状态对应。
可选的，上述时隙相关配置一方面可以包括时隙周期配置和时隙偏置配置，即任意两个TCI状态或任意两个SS配置对应的时隙周期配置和时隙偏置配置不同；另一方面可以包括时隙周期配置、时隙偏置配置和时隙内的符号偏置配置，即任意两个TCI状态或任意两个SS配置对应的时隙周期配置、时隙偏置配置和时隙内的符号偏置配置不同。
举例来说，如图2所示，图中所示的QCL1和QCL2即指两个TCI状态，该两个TCI状态具有相同的CORESET配置和SS配置，但该两个TCI 状态分别具有专属的时隙周期Periodicity T1_WUS和Periodicity T2_WUS、不同的时隙偏置Slot offset O1_WUS和Slot offset O2_WUS、以及不同的时隙内的符号偏置Symbol offset o1_WUS和Symbol offset o2_WUS。
如图3所示，图中所示的QCL1和QCL2即指两个TCI状态，该两个TCI状态具有相同的CORESET配置，不同的SS配置，且两个SS配置分别具有专属的时隙周期Periodicity T_WUS1和PeriodicityT_WUS2、不同的时隙偏置Slot offset O_WUS1和Slot offset O_WUS2、以及不同的时隙内的符号偏置Symbol offset o_WUS1和Symbol offset o_WUS2。
进一步地，可选的，M个TCI状态对应的WUS的发送时刻集中在小于或等于预设时长的时段内。
可以理解，通过上述与M个TCI状态对应的时隙相关配置，使得与M个TCI状态对应的WUS的发送时刻集中在小于或等于预设时长的时段内。如此，可以确保WUS的发送时刻保持在一个便于终端设备接收的范围内，比如所有M个TCI状态对应的WUS的发送时刻集中在5ms的范围内，当然也可以为其他取值。
可选的，在本申请实施例的链路管理方法中，上述M的取值小于或等于M个TCI状态对应的波束恢复参考信号全集或无线链路监测参考信号全集中的参考信号的总数。
可以理解，网络设备为了便于终端设备实现相关链路管理操作，相应的配置了波束恢复参考信号全集或无线链路监测参考信号全集，并通过TCI信息为WUS指示所述全集中的M个参考信号作为与上述M个TCI状态对应的参考信号，也就是说，该M个参考信号构成所述全集的一个子集，该子集中的参考信号的总数小于或等于所述全集中的参考信号的总数。
可选的，在本申请实施例的链路管理方法中，上述步骤103可以执行为不同的具体实施例。
在一个具体实施例中，可选的，上述步骤103可以执行为如下内容：
监测与WUS相关的参考信号的信号质量；
若信号质量监测结果满足目标触发事件，则执行目标触发事件相关的链路管理操作。
在该具体实施例中，可以在监测到与WUS相关的参考信号的信号质量的结果时，即基于信号质量监测结果是否满足目标触发事件的判断，并在判定信号质量监测结果满足条件时，直接唤醒终端设备执行与该具体的目标触发事件相关的链路管理操作。如此，可以在无需考虑WUS解码结果以及解码结果具体的指示内容、以及DRX的激活期是否到达的情况下，即终端设备可以在信号质量监测结果满足目标触发事件的情况下，不进行WUS解码，直接进入DRX的激活期，以实现相应的链路管理操作，比如波束恢复操作或无线链路重建操作，从而提高链路管理效率，同时也可以降低WUS解码开销。
进一步地，在该具体实施例中，本申请实施例的链路管理方法还包括：
若信号质量监测结果不满足目标触发事件，则对基于M个TCI状态检测到的WUS进行解码；
在对WUS解码成功且解码结果指示进入DRX的激活期的情况下，执行进入激活期的操作；
在对WUS解码成功且解码结果指示保持在睡眠期的情况下，执行继续处于睡眠期的操作。
可以理解，在上述信号质量监测结果是否满足目标触发事件的判断中，若判定信号质量监测结果不满足条件时，则需要先对WUS进行解码，并在解码成功的情况下，根据解码结果的具体指示内容相应的操作，即在对WUS的解码结果指示唤醒终端设备的情况下，即刻唤醒其进入DRX的激活期以进行数据接收，而无需等待DRX的激活期到达，否则在解码结果指示保持睡眠的情况下，继续处于DRX的睡眠期以进入下一轮的监测与WUS相关的参考信号的信号质量的操作，直至根据相应的信号质量监测结果是否满足目标触发事件的判断结果，确定是否唤醒终端设备执行相应的链路管理操作。
在另一个具体实施例中，可选的，上述步骤103可以执行为如下内 容：
对基于M个TCI状态检测到的WUS进行解码；
在对WUS解码成功且解码结果指示保持在睡眠期的情况下，监测与WUS相关的参考信号的信号质量；
若信号质量监测结果满足目标触发事件，则执行目标触发事件相关的链路管理操作。
可以理解，在该具体实施例中，可以先对基于M个TCI状态检测到的WUS进行解码，并根据解码成功得到的解码结果进一步确定是否需要监测与该WUS相关的参考信号的信号质量，具体的，在信号质量监测结果满足目标触发事件的情况下，执行相应的链路管理操作，也就是说，在暂时不唤醒终端设备的情况下，依然可以基于与WUS相关的参考信号的信号质量监测结果执行相应的链路管理操作，而不受终端设备仍处于DRX的睡眠期的影响。
需要说明的是，若上述对WUS的解码结果指示进入DRX的激活期，则可以直接唤醒终端设备进入激活期以进行数据接收。
可选的，对于上述任一具体实施例中的监测与所述WUS相关的参考信号的信号质量的操作，可以基于不同的参考信号实现，具体如下：
在一个具体实施例中，可选的，上述与WUS相关的参考信号包括：与M个TCI状态对应的CORESET中的解调参考信号(Demodulation Reference Signal，DMRS)，DMRS与用于表征宽带波束信息的同步信号块(Synchronization Signal Block，SSB)或信道状态信息(Channel State Information，CSI)参考信号准共址。
进一步地，上述监测与WUS相关的参考信号的信号质量的步骤，可以具体执行为：
在WUS对应的带宽部分(Bandwidth Part，BWP)上，监测信号质量。
可以理解，在进行信号质量监测时，可以借助WUS的M个TCI状态对应的CORESET中的解调DMRS实现；也就是说，终端设备可以在M个不同的TCI状态对应的CORESET上监听WUS，进而可以通过 CORESET中的DMRS获取承载WUS的波束对应的信号质量，具体在网络设备为WUS配置了专属的带宽部分BWP的情况下，可以在该BWP上实现与WUS相关的参考信号的信号质量的监测，从而可以在信号质量监测结果满足目标触发事件的情况下，执行目标触发事件相关的链路管理操作。
其中，可以在该BWP上监测到的信号质量结果换算成全带宽上进行物理下行控制信道(Physical Downlink Control Channel，PDCCH)接收的BLER，并进一步根据该BLER是否满足目标触发事件的结果，确定是否执行相应的链路管理事件。其中，该DMRS需与用于表征宽带波束信息的SSB或CSI参考信号一致，即该DMRS与SSB或CSI-RS具有QCL-D类型和QCL-A类型的准共址关系。这样，使得终端设备可以进行更加浅度的唤醒，使得终端设备的芯片内更多的寄存器、时钟等处于睡眠状态，从而进一步降低终端设备的功耗。
需要说明的是，在该与WUS相关的参考信号为与M个TCI状态对应的CORESET中的DMRS的具体实施例中，上述目标触发事件可以包括以下之一：
(1)终端设备的物理层向无线资源控制RRC层上报失步指示，并启动第一计时器。
(2)终端设备的媒体接入控制MAC层的波束失败计数器的计数大于或等于预设次数。
(3)参考信号接收功率RSRP在第一时长内持续小于第一门限，第一门限由网络设备配置或基于第一预设条件确定。
可以理解，用做参考信号接收功率RSRP的评估标准的第一门限可以基于第一预设条件隐式的确定，具体的，该第一预设条件可以包括BLER大于一个设定的比例。
(4)目标信道质量参数在第一时长内持续小于第二门限，目标信道质量参数包括信噪比SINR或信道质量指示CQI，第二门限由网络设备配置或基于第二预设条件确定。
可以理解，用做目标信道质量参数的评估标准的第二门限可以基于第 二预设条件隐式的确定，具体的，该第二预设条件可以包括BLER大于一个设定的比例。
(5)参考信号接收质量RSRQ小于第三门限。
(6)误块率BLER大于第三比例。
需要说明的是，针对上述各目标触发事件可以分别执行相应的链路管理操作，举例来说：
对于上述触发事件(1)，当信号质量监测结果指示链路质量持续低于某一设定门限时，终端设备的物理层向RRC层上报失步指示(Out-Of-Sync，OOS)，并触发RRC层启动第一计时器(即T310计时器)时，可以认为信号质量监测结果满足目标触发事件；进一步可以基于此执行无线链路失败监测操作，进一步在监测到无线链路失败后，比如在第一计时器到时前，终端设备发现没有足够的同步指示(In-Sync，IS)上报，则可以执行无线链路重建操作，也就是说，此时链路管理操作除了包括无线链路失败监测操作外还可以包括无线链路重建操作。
对于上述触发事件(2)，当信号质量监测结果指示链路质量持续低于某一设定门限时，终端设备的物理层向MAC层上报波束失败，即基于信号质量监测结果执行波束监测失败操作时判定波束失败时，由物理层向MAC层上报，并触发MAC层启动波束失败计时器(即BeamFailureDetectionTimer)，在该波束失败计时器到时前的过程中，物理层每向MAC层上报一次BeamFailure，都会使得波束失败计数器(即寄存器BFI_COUNTER)的计数值会增加1；进一步地，如果在波束失败计时器到时的时刻，寄存器的计数值没有达到预设次数BeamFailureInstanceMaxCount，则将寄存器的计数值清零，而如果波束失败计时器到时的时刻，寄存器的计数值大于或等于该预设次数，进一步则可以启动波束恢复流程，也就是说，此时链路管理操作除了包括波束失败监测操作外还可以包括波束恢复操作。
对于上述触发事件(3)～(6)，当信号质量监测结果包括RSRP、目标信道质量参数即SINR或CQI、RSRQ或BLER的情况下，可以基于前述参数的监测结果执行波束失败监测操作和/或无线链路失败监测操作，进 一步在监测到波束失败后可以执行波束失败恢复操作和/或在监测到无线链路失败后可以执行无线链路重建操作。进一步地，在终端设备唤醒进入DRX的激活期后，可以不再使用上述M个TCI状态对应的CORESET中的DMRS监测链路的信号质量，即恢复正常的波束状态和/无线链路状态的监测流程。
需要说明的是，在本申请的其他具体实施例中，与WUS相关的参考信号除了上述DMRS，还可以为与WUS准共址(Quasi Co-Location，QCL)的其他参考信号RS。
在另一个具体实施例中，可选的，上述与WUS相关的参考信号包括：与M个TCI状态对应的M个目标参考信号，M个目标参考信号与WUS准共址。
进一步地，上述M个目标参考信号中的每个目标参考信号可以包括以下之一：
波束失败监测参考信号(Beam Failure Detection RS，BFD-RS)和无线链路监测参考信号(Radio Link Monitoring RS，RLM-RS)中的一个；
与BFD-RS或RLM-RS准共址的其他参考信号。
可选的，参见图4，每个目标参考信号包括BFD-RS和RLM-RS。
进一步地，上述监测与WUS相关的参考信号的信号质量的步骤，可以具体执行为：监测M个目标参考信号的信号质量。
可选的，在该与WUS相关的参考信号为M个目标参考信号，以及每个目标参考信号为上述不包括波束失败恢复参考信号(Beam Failure Recovery RS，BFR-RS)的具体实施例中，上述目标触发事件可以包括以下之一：
(1)终端设备的物理层向无线资源控制RRC层上报失步指示，并启动第一计时器。
(2)终端设备的媒体接入控制MAC层的波束失败计数器的计数大于或等于预设次数。
(3)参考信号接收功率RSRP在第一时长内持续小于第一门限，第一门限由网络设备配置或基于第一预设条件确定。
可以理解，用做参考信号接收功率RSRP的评估标准的第一门限可以基于第一预设条件隐式的确定，具体的，该第一预设条件可以包括BLER大于一个设定的比例。
(4)目标信道质量参数在第一时长内持续小于第二门限，目标信道质量参数包括信噪比SINR或信道质量指示CQI，第二门限由网络设备配置或基于第二预设条件确定。
可以理解，用做目标信道质量参数的评估标准的第二门限可以基于第二预设条件隐式的确定，具体的，该第二预设条件可以包括BLER大于一个设定的比例。
(5)参考信号接收质量RSRQ小于第三门限。
(6)误块率BLER大于第三比例。
需要说明的是，针对上述各目标触发事件可以分别执行相应的链路管理操作，举例来说：
对于上述触发事件(1)，当信号质量监测结果指示链路质量持续低于某一设定门限时，终端设备的物理层向RRC层上报OOS，并触发RRC层启动第一计时器(即T310计时器)时，可以认为信号质量监测结果满足目标触发事件；进一步可以基于此执行无线链路失败监测操作，进一步在监测到无线链路失败后，比如在第一计时器到时前，终端设备发现没有足够的IS上报，则可以执行无线链路重建操作，也就是说，此时链路管理操作除了包括无线链路失败监测操作外还可以包括无线链路重建操作。
对于上述触发事件(2)，当信号质量监测结果指示链路质量持续低于某一设定门限时，终端设备的物理层向MAC层上报波束失败，即基于信号质量监测结果执行波束监测失败操作时判定波束失败时，由物理层向MAC层上报，并触发MAC层启动波束失败计时器(即BeamFailureDetectionTimer)，在该波束失败计时器到时前的过程中，物理层每向MAC层上报一次BeamFailure，都会使得波束失败计数器(即寄存器BFI_COUNTER)的计数值会增加1；进一步地，如果在波束失败计时器到时的时刻，寄存器的计数值没有达到预设次数BeamFailureInstanceMaxCount，则将寄存器的计数值清零，而如果波束失 败计时器到时的时刻，寄存器的计数值大于或等于该预设次数，进一步则可以启动波束恢复流程，也就是说，此时链路管理操作除了包括波束失败监测操作外还可以包括波束恢复操作。
对于上述触发事件(3)～(6)，当信号质量监测结果包括RSRP、目标信道质量参数即SINR或CQI、RSRQ或BLER的情况下，可以基于前述参数的监测结果执行波束失败监测操作和/或无线链路失败监测操作，进一步在监测到波束失败后可以执行波束失败恢复操作和/或在监测到无线链路失败后可以执行无线链路重建操作。进一步地，在终端设备唤醒进入DRX的激活期后，可以不再使用上述M个TCI状态对应的CORESET中的DMRS监测链路的信号质量，即恢复正常的波束状态和/无线链路状态的监测流程。
在又一个具体实施例中，可选的，上述与WUS相关的参考信号包括：与M个TCI状态对应的M个目标参考信号，M个目标参考信号与WUS准共址。
进一步地，上述M个目标参考信号中的每个目标参考信号可以包括以下之一：

与BFD-RS、RLM-RS或BFR-RS准共址的其他参考信号。
可选的，参见图5，每个目标参考信号包括BFD-RS和BFR-RS，以及参见图6，每个目标参考信号包括BFD-RS、BFR-RS和RLM-RS。
进一步地，上述监测与WUS相关的参考信号的信号质量的步骤，可以具体执行为：监测M个目标参考信号的信号质量。
可选的，在该与WUS相关的参考信号为M个目标参考信号，以及每个目标参考信号为上述包括BFR-RS的具体实施例中，上述目标触发事件可以包括以下之一：
参考信号接收功率RSRP在第一时长内持续小于第一门限，第一门限由网络设备配置或基于第一预设条件确定。
可以理解，用做参考信号接收功率RSRP的评估标准的第一门限可以 基于第一预设条件隐式的确定，具体的，该第一预设条件可以包括BLER大于一个设定的比例。
目标信道质量参数在第一时长内持续小于第二门限，目标信道质量参数包括信噪比SINR或信道质量指示CQI，第二门限由网络设备配置或基于第二预设条件确定。
可以理解，用做目标信道质量参数的评估标准的第二门限可以基于第二预设条件隐式的确定，具体的，该第二预设条件可以包括BLER大于一个设定的比例。
参考信号接收质量RSRQ小于第三门限。
误块率BLER大于第三比例。
需要说明的是，针对上述各目标触发事件可以分别执行相应的链路管理操作，举例来说：
当信号质量监测结果包括RSRP、目标信道质量参数即SINR或CQI、RSRQ或BLER的情况下，可以基于前述参数的监测结果执行波束失败监测操作和/或无线链路失败监测操作，进一步在监测到波束失败后可以执行波束失败恢复操作和/或在监测到无线链路失败后可以执行无线链路重建操作。
需要说明的是，在与WUS相关的参考信号为BFD-RS和RLM-RS的情况下，即WUS基于BFD-RS和RLM-RS对应的波束发送，若存在BFR-RS与RLM-RS为基于同一时频资源发送，即符号内的时频域位置、周期和偏置都一致，则上述图2中所示的配置方式中，恢复SS中的周期和符号偏置配置失效，恢复SS采用WUS的配置执行，以及上述图3中所示的配置方式中，可以不再另外配置SS WUS2，而采用恢复SS中的周期和符号偏置配置。
上述各预设的门限、时长、比例、次数等的取值，可以根据链路管理的实际需求设置。
进一步地，需要说明的是，在网络设备为终端设备配置了BFR-RS的情况下，终端设备执行波束恢复操作时，可以基于该BFR-RS、与BFR-RS准共址的参考信号或者目标TCI状态对应的CORESET中的DMRS确定满 足波束恢复条件的波束，其中，目标TCI状态为所述M个TCI状态中与所述BFR-RS对应的TCI状态；其中，具有相同CORESET配置的每个TCI状态，该CORESET与BFR配置中配置的恢复SS的CORESET一致，除了与On-duration中PDCCH一致的TCI状态外，每个TCI状态的SS配置，复用BFR配置中配置的波束恢复SS。而若没有配置BFR-RS，可以从备选波束集合中确定满足波束恢复条件的波束，具体的，备选恢复波束集合基于除M个TCI状态对应的CORESET配置和SS配置外的其他CORESET配置、SS配置或SS周期配置中的解调参考信号DMRS的标识确定，该标识由网络设备通过RRC消息配置。
可选的，在本申请实施例的链路管理方法中，若网络设备为终端设备配置了备选恢复波束集合，则上述步骤103还可以执行为如下操作：
对基于M个TCI状态检测到的WUS进行解码；
在对WUS解码成功且解码结果指示保持在睡眠期、以及存在满足波束恢复条件的备选恢复波束集合的情况下，若波束失败监测判定波束失败，则不执行波束恢复操作；
在对WUS解码失败或者对WUS解码成功且解码结果指示进入DRX的激活期的情况下，若波束失败监测判定波束失败，则基于满足波束恢复条件的备选恢复波束集合执行波束恢复操作。
可以理解，为了进一步降低终端设备的功耗，在对WUS解码成功且解码结果指示保持在睡眠期、以及存在满足波束恢复条件的备选恢复波束集合的情况下，若执行波束失败监测操作的结果为判定波束失败，可以暂时先不执行波束恢复操作，以在终端设备没有业务时，不会因链路状态发生变化而频繁唤醒，从而有效的降低了终端设备的功耗。以及在对WUS解码解码失败或解码成功且解码结果指示进入激活期，且发现已有波束失败的标记时，可以从波束恢复条件的备选恢复波束集合中找到可用的波束，进行波束恢复，并可以通过随机接入信道(Random Access Channel，RACH)通知网络设备进入了波束的恢复重建，如此，可以避免波束的频繁重建。其中，满足波束恢复条件可以指信号质量满足一定的预设条件。
可选的，在本申请实施例的上述备选恢复波束集合的一个具体实施例 中，在波束恢复参考信号全集或无线链路监测参考信号全集包括BFD-RS和RLM-RS中的至少一个的情况下，上述备选恢复波束集合基于除M个TCI状态对应的CORESET配置和SS配置外的其他CORESET配置、SS配置或SS周期配置中的解调参考信号DMRS的标识确定，标识由网络设备通过RRC消息配置，其中，SS周期即指SS配置的一个时隙周期。
其中，该标识对应的DMRS与用于表征宽带波束信息的同步信号块SSB或信道状态信息CSI参考信号一致，即该DMRS与SSB或CSI-RS具有QCL-D类型和QCL-A类型的准共址关系。
可选的，在本申请实施例的上述备选恢复波束集合的另一个具体实施例中，在波束恢复参考信号全集或无线链路监测参考信号全集包括BFR-RS和BFD-RS的情况下、或者在波束恢复参考信号全集或无线链路监测参考信号全集包括BFR-RS、BFD-RS和RLM-RS的情况下，上述备选恢复波束集合基于BFR-RS、与BFR-RS准共址的参考信号或者目标TCI状态对应的CORESET中的DMRS确定，目标TCI状态为M个TCI状态中与BFR-RS对应的TCI状态。
也就是说，网络设备为终端设备配置备选恢复波束集合时，在不存在BFR-RS的情况下，可以从备选波束集合中确定满足波束恢复条件的波束，具体的，备选恢复波束集合基于除M个TCI状态对应的CORESET配置和SS配置外的其他CORESET配置、SS配置或SS周期配置中的解调参考信号DMRS的标识确定，该标识由网络设备通过RRC消息配置。而若存在BFR-RS，则可以基于该BFR-RS、与BFR-RS准共址的参考信号或者目标TCI状态对应的CORESET中的DMRS确定满足波束恢复条件的波束，其中，目标TCI状态为M个TCI状态中与BFR-RS对应的TCI状态；其中，具有相同CORESET配置的每个TCI状态，该CORESET与BFR配置中配置的恢复SS的CORESET一致，除了与On-duration中PDCCH一致的TCI状态外，每个TCI状态的SS配置，复用BFR配置中配置的波束恢复SS。
综上可知，在本申请实施例的链路管理方法中，上述链路管理操作还可以包括波束恢复操作和无线链路重建操作中的至少一个，也就是说，基 于上述M个TCI状态，不仅可以实现波束是否失败的监测和/或无线链路是否失败的监测，还可以在监测到波束失败的情况下，基于该M个TCI状态执行波束恢复操作，和/或在监测到无线链路失败的情况下，基于该M个TCI状态执行无线链路重建操作。当然，还可以基于该M个TCI状态以外的其他资源，实现波束恢复操作和无线链路重建操作中的至少一个。
参见图7所示，本申请实施例提供一种唤醒信号检测方法，由网络设备执行，该方法可以包括以下内容：

可选的，对于物理层L层或无线资源控制RRC层L3层的信号质量测量，可以基于波束失败监测参考信号BFD-RS全集和无线链路监测参考信号RLM-RS全集中的至少一个进行。
步骤203：根据信号质量监测结果是否满足目标触发事件的判断结果，确定是否检测唤醒信号WUS。
该实施例，对于处于连接态非连续接收DRX的睡眠期的终端设备，可以在检测WUS前，监测物理层或RRC层的信号质量，并可以根据对信号质量监测结果是否满足目标触发事件的判断结果，确定是否检测WUS。如此，可以降低WUS检测的功耗，从而降低终端设备的功耗。
进一步地，在信号质量监测结果满足目标触发事件的情况下，直接唤醒进入DRX的激活期，否则检测WUS。
可选的，上述目标触发事件包括以下之一：
(1)终端设备的物理层向无线资源控制RRC层上报失步指示，并启动第一计时器。
(2)终端设备的媒体接入控制MAC层的波束失败计数器的计数大于或等于预设次数。
(3)参考信号接收功率RSRP在第一时长内持续小于第一门限，第一门限由网络设备配置或基于第一预设条件确定。
可以理解，用做参考信号接收功率RSRP的评估标准的第一门限可以 基于第一预设条件隐式的确定，具体的，该第一预设条件可以包括BLER大于一个设定的比例。
(4)目标信道质量参数在第一时长内持续小于第二门限，目标信道质量参数包括信噪比SINR或信道质量指示CQI，第二门限由网络设备配置或基于第二预设条件确定。

(5)参考信号接收质量RSRQ小于第三门限。
(6)误块率BLER大于第三比例。
需要说明的是，针对上述各目标触发事件可以分别执行相应的链路管理操作，举例来说：
对于上述触发事件(1)，当信号质量监测结果指示链路质量持续低于某一设定门限时，终端设备的物理层向RRC层上报失步指示OOS，并触发RRC层启动第一计时器(即T310计时器)时，可以认为信号质量监测结果满足目标触发事件；进一步可以基于此直接唤醒进入DRX的激活期，不检测WUS，否则检测WUS。
对于上述触发事件(2)，当信号质量监测结果指示链路质量持续低于某一设定门限时，终端设备的物理层向MAC层上报波束失败，并触发MAC层启动波束失败计时器(即BeamFailureDetectionTimer)，在该波束失败计时器到时前的过程中，物理层每向MAC层上报一次BeamFailure，都会使得波束失败计数器(即寄存器BFI_COUNTER)的计数值会增加1；进一步地，如果在波束失败计时器到时的时刻，寄存器的计数值没有达到预设次数BeamFailureInstanceMaxCount，则将寄存器的计数值清零，而如果波束失败计时器到时的时刻，寄存器的计数值大于或等于该预设次数，进一步则可以基于此直接唤醒进入DRX的激活期，不检测WUS，否则检测WUS。
对于上述触发事件(3)～(6)，当信号质量监测结果包括参考信号接收功率RSRP、目标信道质量参数即信噪比SINR或信道质量指示 CQI、参考信号接收质量RSRQ或BLER的情况下，可以在前述参数的监测结果满足相应的门限条件时，直接唤醒进入DRX的激活期，不检测WUS，否则检测WUS。
需要说明的是，上述步骤101，在网络设备配置了用于指示唤醒信号WUS的至少一个TCI状态的传输配置指示TCI信息的情况下，还可以基于与该M个TCI状态对应的M个目标参考信号实现信号质量的监测，其中，M个目标参考信号与WUS准共址。
可选的，在一个具体实施例中，M个目标参考信号中的每个目标参考信号包括以下之一：
波束失败监测参考信号BFD-RS和无线链路监测参考信号RLM-RS中的一个；
与BFD-RS或RLM-RS准共址的其他参考信号。
相应的目标触发事件包括上述(1)～(6)中的一个，在此不再赘述。
可选的，在另一个具体实施例中，M个目标参考信号中的每个目标参考信号包括以下之一：
BFD-RS和波束失败恢复参考信号BFR-RS；
BFD-RS、BFR-RS和RLM-RS；
与BFD-RS、RLM-RS或BFR-RS准共址的其他参考信号。
相应的目标触发事件同上述(3)～(6)中的一个，在此不再赘述。
上述各预设的门限、时长、比例、次数等的取值，可以根据链路管理的实际需求设置。
参见图8所示，本申请实施例提供一种链路管理方法，由网络设备执行，该方法可以包括以下内容：
步骤301：向终端设备发送传输配置指示TCI信息，TCI信息用于指示唤醒信号WUS的M个TCI状态，M为正整数。
其中，终端设备用于在处于连接态非连续接收DRX的睡眠期的情况下，基于M个TCI状态，执行链路管理操作，链路管理操作包括波束失败监测操作和无线链路失败监测操作中的至少一个。
在本申请实施例中，通过为终端设备配置用于指示唤醒信号WUS的至少一个TCI状态的传输配置指示TCI信息，使终端设备在处于连接态非连续接收DRX的睡眠期时，可以基于该M个TCI状态执行相应的链路管理操作时，至少可以执行波束失败监测和无线链路失败监测中的一个操作。如此，可以解决现有方案中在连接态DXR的睡眠期终端设备无法进行波束失败或无线链路失败监测的问题，从而使得波束失败监测和无线链路失败监测不受WUS解码结果和连接态下DRX配置情况的影响，保证终端设备对链路状态的跟踪性能，即能够及时且准确地监测到波束失败和/或无线链路失败的情况，并能够降低终端设备的功耗；进一步地，由于终端设备可以及时且准确地监测到波束失败和/或无线链路失败的情况，则有助于终端设备在DRX的激活期即将醒来时，提前进行波束恢复或无线链路重建的相关准备，避免终端设备醒来进入DRX的激活期后由于确定用于波束恢复或无线链路重建的资源的时延，影响数据接收的效率。
可以理解，对于终端设备来说，在M个TCI状态为多个时，网络设备基于M个TCI状态中的任意两个TCI状态发送的WUS相同，即在对WUS解码成功的情况下其指示终端设备保持在DRX的睡眠期或从DRX的睡眠期进入DRX的激活期的解码结果是相同的，也就是说，终端设备认为网络设备基于M个TCI状态发送的所有WUS所携带的醒或睡的消息是一致的。同时，借助多个TCI状态可以提高WUS的接收可靠性。
可选的，在本申请实施例的链路管理方法中，对于上述M个TCI状态，可以具有不同的配置方案，使得终端设备基于M个TCI状态对应的波束检测WUS的方案具备多样性。
在一个具体实施例中，上述M个TCI状态中任意两个TCI状态对应的控制资源集CORESET配置和搜索空间SS配置相同、时隙相关配置不同。
可以理解，在M个TCI状态为多个的情况下，多个TCI状态中的任意两个TCI状态可以具有相同的CORESET配置和相同的SS配置，但该多个TCI状态中的每个TCI状态可以具有专属的时隙相关配置，即任意两个TCI状态之间的时隙相关配置不同。也就是说，一个CORESET上有一 个SS，该SS配置多个不同的时隙相关配置，一个时隙相关配置与一个TCI状态对应。
在另一个具体实施例中，上述M个TCI状态中任意两个TCI状态对应的CORESET配置相同、SS配置不同，每个SS配置有独立的时隙相关配置。
可以理解，在M个TCI状态为多个的情况下，多个TCI状态中的任意两个TCI状态可以具有相同的CORESET配置和不同的SS配置，具体该M个TCI状态对应的M个SS配置中的每个SS配置可以具有独立专属的时隙相关配置。也就是说，一个CORESET上有多个SS，每个SS对应配置一个时隙相关配置，一个时隙相关配置与一个TCI状态对应。
可选的，上述时隙相关配置一方面可以包括时隙周期配置和时隙偏置配置，即任意两个TCI状态或任意两个SS配置对应的时隙周期配置和时隙偏置配置不同；另一方面可以包括时隙周期配置、时隙偏置配置和时隙内的符号偏置配置，即任意两个TCI状态或任意两个SS配置对应的时隙周期配置、时隙偏置配置和时隙内的符号偏置配置不同。
具体可以参见前述图2和图3中的示例，如图2所示，图中所示的QCL1和QCL2即指两个TCI状态，该两个TCI状态具有相同的CORESET配置和SS配置，但该两个TCI状态分别具有专属的时隙周期Periodicity T1_WUS和Periodicity T2_WUS、不同的时隙偏置Slot offset O1_WUS和Slot offset O2_WUS、以及不同的时隙内的符号偏置Symbol offset o1_WUS和Symbol offset o2_WUS。如图3所示，图中所示的QCL1和QCL2即指两个TCI状态，该两个TCI状态具有相同的CORESET配置，不同的SS配置，且两个SS配置分别具有专属的时隙周期Periodicity T_WUS1和PeriodicityT_WUS2、不同的时隙偏置Slot offset O_WUS1和Slot offset O_WUS2、以及不同的时隙内的符号偏置Symbol offset o_WUS1和Symbol offset o_WUS2。
进一步地，可选的，M个TCI状态对应的WUS的发送时刻集中在小于或等于预设时长的时段内。
可以理解，通过上述与M个TCI状态对应的时隙相关配置，使得与 M个TCI状态对应的WUS的发送时刻集中在小于或等于预设时长的时段内。如此，可以确保WUS的发送时刻保持在一个便于终端设备接收的范围内，比如所有M个TCI状态对应的WUS的发送时刻集中在5ms的范围内，当然也可以为其他取值。
可选的，在本申请实施例的链路管理方法中，上述M的取值小于或等于M个TCI状态对应的波束恢复参考信号全集或无线链路监测参考信号全集中的参考信号的总数。
可以理解，网络设备为了便于终端设备实现相关链路管理操作，会相应的配置波束恢复参考信号全集或无线链路监测参考信号全集，并通过TCI信息为WUS指示所述全集中的M个参考信号作为与上述M个TCI状态对应的参考信号，也就是说，该M个参考信号构成所述全集的一个子集，该子集中的参考信号的总数小于或等于所述全集中的参考信号的总数。
可选的，在本申请实施例的链路管理方法中，上述与M个TCI状态对应的M个目标参考信号与WUS准共址；
其中，M个目标参考信号用于终端设备进行信号质量监测，并在信号质量监测结果满足目标触发事件的情况下，执行目标触发事件相关的链路管理操作。
可选的，在本申请实施例的链路管理方法中，对于与M个TCI状态对应的M个目标参考信号中的每个目标参考信号可以通过不同的具体实施例进行配置。
在一个具体实施例中，上述每个目标参考信号包括以下之一：
波束失败监测参考信号BFD-RS和无线链路监测参考信号RLM-RS中的一个；
与BFD-RS或RLM-RS准共址的其他参考信号。
可选的，参见图4，每个目标参考信号包括BFD-RS和RLM-RS。
其中，相应的，目标触发事件可以包括如下之一：
(1)终端设备的物理层向无线资源控制RRC层上报失步指示，并启动第一计时器。
(2)终端设备的媒体接入控制MAC层的波束失败计数器的计数大于或等于预设次数。
(3)参考信号接收功率RSRP在第一时长内持续小于第一门限，第一门限由网络设备配置或基于第一预设条件确定。
可以理解，用做参考信号接收功率RSRP的评估标准的第一门限可以基于第一预设条件隐式的确定，具体的，该第一预设条件可以包括BLER大于一个设定的比例。
(4)目标信道质量参数在第一时长内持续小于第二门限，目标信道质量参数包括信噪比SINR或信道质量指示CQI，第二门限由网络设备配置或基于第二预设条件确定。
可以理解，用做目标信道质量参数的评估标准的第二门限可以基于第二预设条件隐式的确定，具体的，该第二预设条件可以包括BLER大于一个设定的比例。
(5)参考信号接收质量RSRQ小于第三门限。
(6)误块率BLER大于第三比例。
需要说明的是，针对上述各目标触发事件可以分别执行相应的链路管理操作，举例来说：
对于上述触发事件(1)，当信号质量监测结果指示链路质量持续低于某一设定门限时，终端设备的物理层向RRC层上报OOS，并触发RRC层启动第一计时器(即T310计时器)时，可以认为信号质量监测结果满足目标触发事件；进一步可以基于此执行无线链路失败监测操作，进一步在监测到无线链路失败后，比如在第一计时器到时前，终端设备发现没有足够的IS上报，则可以执行无线链路重建操作，也就是说，此时链路管理操作除了包括无线链路失败监测操作外还可以包括无线链路重建操作。
对于上述触发事件(2)，当信号质量监测结果指示链路质量持续低于某一设定门限时，终端设备的物理层向MAC层上报波束失败，即基于信号质量监测结果执行波束监测失败操作时判定波束失败时，由物理层向MAC层上报，并触发MAC层启动波束失败计时器(即BeamFailureDetectionTimer)，在该波束失败计时器到时前的过程中，物 理层每向MAC层上报一次BeamFailure，都会使得波束失败计数器(即寄存器BFI_COUNTER)的计数值会增加1；进一步地，如果在波束失败计时器到时的时刻，寄存器的计数值没有达到预设次数BeamFailureInstanceMaxCount，则将寄存器的计数值清零，而如果波束失败计时器到时的时刻，寄存器的计数值大于或等于该预设次数，进一步则可以启动波束恢复流程，也就是说，此时链路管理操作除了包括波束失败监测操作外还可以包括波束恢复操作。
对于上述触发事件(3)～(6)，当信号质量监测结果包括RSRP、目标信道质量参数即SINR或CQI、RSRQ或BLER的情况下，可以基于前述参数的监测结果执行波束失败监测操作和/或无线链路失败监测操作，进一步在监测到波束失败后可以执行波束失败恢复操作和/或在监测到无线链路失败后可以执行无线链路重建操作。
在另一个具体实施例中，上述每个目标参考信号包括以下之一：

需要说明的是，在与WUS相关的参考信号为BFD-RS和RLM-RS的情况下，即WUS基于BFD-RS和RLM-RS对应的波束发送，若存在BFR-RS与RLM-RS为基于同一时频资源发送，即符号内的时频域位置、周期和偏置都一致，则上述图2中所示的配置方式中，恢复SS中的周期和符号偏置配置失效，恢复SS采用WUS的配置执行，以及上述图3中所示的配置方式中，可以不再另外配置SS WUS2，而采用恢复SS中的周期和符号偏置配置。

上述各预设的门限、时长、比例、次数等的取值，可以根据链路管理的实际需求设置。
可选的，在本申请实施例的链路管理方法中，与M个TCI状态对应的CORESET中的解调参考信号DMRS，也可以用于终端设备进行信号质量监测，并在信号质量监测结果满足上述目标触发事件的情况下，执行目标触发事件相关的链路管理操作，其中，DMRS与用于表征宽带波束信息的同步信号块SSB或信道状态信息CSI参考信号准共址。进一步地，网络设备可以为WUS配置BWP，以使终端设备在在WUS对应的带宽部分BWP上，监测与M个TCI状态对应的CORESET中的DMRS的信号质量。
