本申请实施例中的配置信息通过以下信令中的至少一种发送：系统消息、物理层信令(例如下行控制信息(Downlink Control Information，DCI))、无线资源控制(Radio Resource Control，RRC)信令和媒体接入控制单元(Media Access Control Control Element，MAC CE)。
为便于理解本申请实施例的技术方案，对本申请相关的无线链路监测(Radio Link Monitoring，RLM)机制进行说明。
RLM用于监听评估服务小区的下行链路的信道质量，产生同步(In-Sync，IS)指示和不同步(Out-Of-Sync，OSS)指示。
在一些实施例中，RLM包括但不限于对下行带宽部分(BandWidth Part，BWP)上的无线链路监测参考信号(RLM-RS)进行测量，该RLM-RS可以包括但不限于(Synchronization Signal Block，SSB)或信道状态信息参考信号(Channel State Information Reference Signal，CSI-RS)。
RLM可以适用于主小区(PCell)或主辅小区(PSCell)，例如，SA NR、NR-DC和NE-DC模式的主小区，或者，NR-DC和EN-DC模式的主辅小区。
在一些实施例中，网络设备可以给终端设备配置N个无线链路监测参考信号(Radio link monitoring reference signal，RLM-RS)用来进行无线链路监测，评估无线链路质量，其中，无线链路 质量通过假设的物理下行控制信道(Physical Downlink Control Channel，PDCCH)误块率(Block Error Rate，BLER)进行判断。
在一些实施例中，以RLM-RS为SSB为例，RLM的测量时间(或称，测量评估时间，评估时间，测量评估周期，评估周期Evaluation period)可以以SSB的周期T SSB为单位(不用配置测量间隔(gap))。可选地，在该测量评估时间内，终端设备可以根据SSB的测量结果确定是否上报IS，或是否上报OSS指示。
在一些实施例中，对于FR1频段，若SSB的周期与测量间隔的周期(MGRP)不重叠，无需对测量评估时间进行缩放。此情况下，可选地，OOS的测量评估周期为10*T SSB，IS的测量评估周期为10*T SSB)；否则，对测量评估时间进行缩放，缩放因子为P＝1/(1–T SSB/MGRP)倍。
在一些实施例中，对于FR2频段，由于T SSB可能与同步信号块测量时间配置(synchronization signal block measurement timing configuration，SMTC)的周期T SMTCperiod或MGRP发生重叠，因此，需要对测量评估时间进行缩放。
在一些实施例中，网络设备可以配置IS门限Q in和OSS门限Q out，Q out定义为下行无线链路无法可靠接收的级别，Qin定义为下行无线链路质量能够可靠接收的级别，其中，该Qin的接收可靠性显著高于Q out。
在一些实施例中，IS门限Q in和OSS门限Q out通过PDCCH BLER表征。例如，Q in为2％PDCCH BLER，Q out为10％PDCCH BLER。
在一些实施例中，对于RLM，终端设备的物理层可以执行如下操作：
例如，若RLM-RS的信号质量低于Q out，终端设备发送一个层1(L1)的OSS指示给终端设备的高层(例如层3(L3))。
例如，若RLM-RS的信号质量高于Q in，终端设备发送一个L1的IS指示给终端设备的高层，例如L3。其中，IS指示和OSS指示统称为L1指示。
例如，终端设备的L3对测量评估周期内的所有指示(包括IS指示和OSS指示)做L3滤波。
在一些实施例中，层1可以指物理层，层3可以指无线资源控制(Radio Resource Control，RRC)成。
在一些实施例中，两个连续的L1指示至少间隔T Indication_interval。
可选地，T Indication_interval可以为max(10ms,T RLM-RS,M)或者，在使用DRX的情况下，T Indication_interval也可以为max(10ms,1.5*DRX周期长度(DRX_cycle_length),1.5*T RLM-RS,M)，其中，T RLM-RS,M是用于被监测的小区的所有RLM-RS资源中的最小的参考信号周期。
其中，T RLM-RS,M表示RLM-RS的周期。
在一些实施例中，L3滤波的方法可以是基于RRC配置的，或者也可以是基于网络实现的。例如，可以按照向前做卷积平均的方法。
结合图2，说明RLM中，从物理层到高层的整体流程。
如图2所示，终端设备可以对每个被监测的小区上的参考信号进行测量，得到该小区上的每个参考信号的测量结果，进一步基于该参考信号的测量结果可以得到针对该参考信号的评估结果，例如是IS还是OOS，然后根据被监测的小区上的所有参考信号的评估结果，得到该小区的评估结果，进一步根据所有小区的评估结果，确定是否触发RLF，若确定不触发RLF，则解除T310定时，或者，若，触发RLF，则触发RRC连接重建立。
结合图3，说明在RLM中，终端设备的高层的计数操作：
1、网络设备预先配置给终端设备针对IS和OOS的门限值，即Q in和Q out，该门限值以PDCCH BLER大小的形式给出。
2、网络设备预先配置终端设备针对RLM的测量资源(包括参考信号资源)，终端设备通过在给定资源上进行测量，判断当前的信道质量。
3、当终端设备检测发现所有的RLM-RS的质量均小于OOS门限Q out时，终端设备的物理层上报L1的OOS指示至终端设备的高层。
4、当终端设备检测发现至少有一个RLM-RS大于IS门限Q in时，终端设备的物理层上报L1的IS指示至终端设备的高层。
5、当终端设备的高层检测到N310(或称，OSS计数器)连续的OOS指示上报后，启动定时器T310(或称RLF定时器)，并在T310定时器内检测是否有N311(或称，IS计数器)个连续的IS指示上报，如果有，则停止定时器T310，如果没有，则认为发生了无线链路失败(Radio Link Failure，RLF)事件，并上报RLF，以及触发后续的流程，比如RRC连接重建立。
在一些情况中，在终端设备确定发送RLF事件时，需要在40ms内关闭发射射频单元(Tx RF)。
为便于理解本申请实施例的技术方案，对本申请相关波束检测(Beam Detection，BD)机制进行说明。
在一些场景中，针对主小区(PCell)和辅主小区(PSCell)设计了波束失败恢复(Beam Failure Recovery，BFR)机制。主要包括如下步骤：
波束失败检测(Beam Failure Detection，BFD)；
新波束选择(New Beam Identification，NBI)，或者，候选波束检测(Candidate Beam Detecion，CBD)；
波束失败恢复请求(Beam Failure Recovery ReQest，BFRQ)；
终端设备监听网络侧对BFRQ的响应。
在一些实施例中，波束检测可以包括BFD和CBD。
对于BFR，终端设备的物理层对波束失败检测参考信号(BFD-RS)进行测量，并根据测量结果来判断是否发生波束失败事件。BFD-RS可以是周期性的CSI-RS或SSB。判断条件可以为：如果检测出全部服务波束(serving beam)对应的链路质量均很差(例如均小于一个门限)时，则确定为一次波束失败实例(beam fai1ure instance，BFI)，终端设备的物理层上报给终端设备的高层(例如媒体接入控制(Media Access Control，MAC)层)一个BFI指示。反之，如果终端设备的物理层确定没有发生BFI，则不向高层发送BFI指示。终端设备的高层使用计数器(记为BFD计数器)和定时器(记为BFD定时器)对终端设备的物理层上报的BFI指示进行计数，每收到一个BFI则重启定时器，定时器超时则计数器重新计数，当计数器达到网络配置的最大次数时，终端设备认为发生了波束失败事件。
对于NBI或CBD，终端设备会对一组候选波束进行测量，从中选择满足一定门限的波束作为新波束。然后终端设备通过波束失败恢复请求流程BFRQ，通知网络设备发生了波束失败，并且上报新波束。网络设备收到一个终端设备发送的BFRQ信息后，确定所述终端发生了波束失败，选择从新波束上发送PDCCH，终端设备在新波束上收到网络设备发送的PDCCH则认为正确接收了网络侧的响应信息。至此，波束失败恢复流程成功完成。
图4是本申请相关的一种波束失败恢复流程的示意性图。如图4所示，可以包括如下步骤：
S201，终端设备进行波束失败检测。
S202，确定是否发生波束失败事件。
若是，则执行S203，若否，则返回S201。
S203，确定是否配置专属BFR资源。
若是，则执行S204，若否，则执行S205。
S204，执行新波束选择确定是否选择到满足条件的新波束。
若是，则执行S206，否则，执行S205。
S205，基于该新波束发起非竞争的随机接入。
S206，发起基于竞争的随机接入。
S207，对于基于竞争的随机接入，确定是否随机接入成功。
若是，则执行S210，否则，执行S211。
S208，对于非竞争的随机接入，确定是否接收到网络的响应。
若是，则执行S210，否则执行S209。
S209，确定发起随机接入的次数是否超过规定次数。
若是执行S211，否则返回S206。
S210，确定波束恢复成功。
S211，确定无线链路失。
综上，判断RLF可以包括如下两种方式：
方式1：根据前述定时器T310，计数器N310和N311判断是否发生RLF。
方式2：波束检测失败，即BFD失败并且CBD失败。
从上述RLM和BD流程可以看出，RLM和BD都属于L1测量，测量模型主要包括如下参数：
L1测量评估时间，参考信号配置，L1上报配置(包括滤波器配置，计数器配置和定时器配置)和事件的判断准则(包括事件对应的门限)。
1、L1测量评估时间及参考信号配置。
以基于SSB的RLM和BFD(对于FR1，不配置DRX时)为例：
1.1、RLM对应的测量评估时间：
用于上报OSS指示的测量评估时间T Evaluate_out_SSB(ms)＝Max(200，Ceil(10×P)×T SSB)， 其中，P表示缩放因子，Ceil表示向上取整。
用于上报IS指示的测量评估时间T Evaluate_in_SSB(ms)＝Max(100，Ceil(5×P)×T SSB)，其中，P表示缩放因子，Ceil表示向上取整。
1.2、BFD对应的测量评估时间：
用于BFD的测量评估时间T Evaluate_BFD_SSB＝Max(50，Ceil(5×P)×T SSB)，其中，P表示缩放因子，Ceil表示向上取整。
由上可见，RLM比BFD的测量评估周期要长，BFD的执行更频繁更密集。
2、上报L1指示的时间间隔(或称L1指示的上报周期)：
2.1、RLM对应的上报周期
例如，上报周期T Indication_interval可以为max(10ms,T RLM-RS,M)。
2.2、BFD对应的上报周期
BFD的上报周期T Indication_interval＝max(2ms,T SSB-RS,M))或max(2ms,T CSI-RS,M)。其中，T SSB-RS,M是用于被监测的小区的所有SSB资源中的最小的周期，T CSI-RS,M是用于被监测的小区的所有CSI-RS资源中的最小的周期。
3、事件的判断准则
3.1、RLM对应的门限包括前述Q in和Q out。
例如，终端设备根据Q in是否上报IS，根据Q out确定是否上报OOS。
RLM中，OOS的判断是基于假想的PDCCH的信号干扰噪声比(Signal to Interference plus Noise Ratio，SINR)评估(例如10％的门限)，OOS指示由终端设备的层3来统计。在小区对应的所有参考信号资源(如CSI-RS resource)上的测量结果均满足OOS门限时才判断该小区为链路失败。
3.2、BFD对应的门限和CBD对应的门限对于BFD，终端设备基于假想的PDCCH的信号干扰噪声比(Signal to Interference plus Noise Ratio，SINR)低于一个门限判断评估BFD。
例如，终端设备根据BFD对应的门限确定是否发生波束失败实例。
候选波束检测用于寻找新波束，CBD可以是测量层1参考信号接收功率(Layer1-Reference Signal Receiving Power，L1-RSRP)来选择新beam，RSRP的门限可以由媒体接入控制(Media Access Control，MAC)层决定。
因此，RLM和BD的流程大致相同，但是执行测量所基于的参数不同，因此，如何执行RLM和BD以降低终端设备的复杂度是一项亟需解决的问题。
有鉴于此，本申请实施例提供的一种技术方案，由于RLM和BD都是对L1的参考信号进行测量，且大概率采用相同的参考信号配置进行测量，因此考虑RLM和BD采用统一的测量模型进行测量，有利于降低终端设备的复杂度。
为便于理解本申请实施例的技术方案，以下通过具体实施例详述本申请的技术方案。以上相关技术作为可选方案与本申请实施例的技术方案可以进行任意结合，其均属于本申请实施例的保护范围。本申请实施例包括以下内容中的至少部分内容。
图5是根据本申请实施例的无线通信的方法300的示意性交互图，如图5所示，该方法300包括如下内容：
S310，终端设备根据第一测量模型执行无线链路监测RLM和波束检测，其中，所述波束检测包括波束失败检测BFD和候选波束检测CBD。
因此，终端设备可以采用统一的测量模型执行RLM和波束检测，有利于降低终端设备的复杂度。
需要说明的是，在本申请实施例中，终端设备基于统一的测量模型执行RLM和波束检测，可以指终端设备执行RLM和波束检测的模型结构相同，或者说，执行RLM和波束检测的流程相同。
应理解，在本申请实施例中，波束可以替换为参考信号，对应的，波束检测也可以表述为参考信号检测，波束失败检测也可以表述为参考信号失败检测，候选波束检测也可以表述为候选参考信号检测。

在一些实施例中，对于BFD，层1测量可以指对用于BFD的参考信号进行测量，或者说，对用于BFD的波束进行测量。
在一些实施例中，对于BFD，层1指示可以包括波束失败实例BFI指示。
在一些实施例中，RLM对应的OOS指示和BFD对应的BFI指示可以采用统一的模型参数，例如统一的判断门限，和/或，统一的计数器门限等。
在一些实施例中，对于CBD，层1测量可以指对用于CBD的参考信号进行测量，或者说，对用于CBD的波束进行测量以选择新波束。
在一些实施例中，RLM对应的IS评估和CBD中的新波束选择可以采用统一的模型参数，例如，IS的判断和新波束选择可以采用统一的判断门限，和/或，统一的计数器门限等。
在一些实施例中，用于RLM的参考信号配置和用于BFD的参考信号配置可以采用相同的配置，这样，RLM和BFD可以统一测量，有利于降低终端设备的复制度。
例如，用于RLM和BFD的参考信号配置可以配置一组信号质量较优(根据历史数据判断)的参考信号，这样，在这些参考信号的质量变差时，可以认为发生无线链路失败或波束失败。
又例如，用于RLM和BFD的参考信号配置可以配置PCell和PSCell上的参考信号。
在一些实施例中，对于RLM，根据上报的层1指示进行事件的判断可以包括：
根据终端设备的物理层上报的OOS指示确定是否触发RLF；或者
根据终端设备的物理层上报的OOS指示和IS指示确定是否触发RLF。
作为示例，在上报的OOS指示的数量达到计数器门限时，认为发生了RLF事件，或者，根据物理层上报的OOS指示和IS指示触发RLF，例如，当终端设备的高层检测到N310个连续的OOS指示上报后，启动定时器，并在定时器内检测是否有N311个连续的IS指示上报，如果有，则停止定时器，如果没有，则认为发生了RLF事件。
在一些实施例中，对于BFD，根据上报的层1指示进行事件的判断可以包括：
根据终端设备的物理层上报的BFI指示确定是否波束失败。
例如，在终端设备的物理层上报的BFI指示的数量达到计数器门限时，确定波束失败。

进一步地，在统一的LR模型中，对于波束检测，终端设备可以对参考信号集合2进行测量以选择新波束，对于RLM，终端设备可以继续对参考信号集合2中的参考信号进行测量，以确定这些参考信号对应的链路质量。
进一步地，若在定时器运行期间，终端设备未发现新波束或者不存在质量好的链路，则触发RLF。
即，BFD失败且CBD失败，则确定RLF，或者，若参考信号配置中的所有参考信号对应的链路质量均不满足上述门限1，则确定RLF。

例如，基于相同的测量评估时间信息执行RLM和波束检测。
又例如，基于相同的参考信号配置执行RLM和波束检测。
又例如，基于相同的门限(包括门限1，可选还包括门限2)确定是否上报层1指示。

可选地，对于RLM，在参考信号的质量高于门限2(对应前述实施例中的Q in)时，上报IS指示。
作为示例，对于BFD，在参考信号的质量低于该门限1时，上报BFI指示。
在一些实施例中，用于RLM和波束检测的参考信号配置用于配置参考信号集合1和参考信号集合2，例如，在统一的LM模型中，终端设备可以基于参考信号集合1进行RLM和BFD。
进一步可选地，基于相同的计数值门限进行事件判断。
例如，在终端设备的物理层上报的层1指示的数量达到计数值门限时，可以认为链路质量不好，或者波束质量不好。
在一些实施例中，对于RLM，在参考信号集合1中的所有参考信号对应的链路质量或波束质量均不好时，可以触发RLF。
在一些实施例中，对于BFD，在参考信号集合2中的所有参考信号对应的链路质量或波束质量均不好时，可以触发执行CBD。
进一步基于统一的LR模型进行链路恢复或波束恢复。
在一些实施例中，对于波束检测，终端设备执行CBD，例如，对参考信号集合2中的参考信号进行测量以选择新波束，并基于选择的新波束发起随机接入过程。
在一些实施例中，对于RLM，终端设备基于参考信号集合2中的参考信号，或者，在参考信号集合2中的参考信号对应的小区上发起随机接入过程。
进一步地，终端设备监听网络设备的响应，若接收到网络设备的响应，确定波束失败恢复成功，或者，链路恢复成功。若未收到网络设备的响应，通过其他参考信号或波束重新发起随机接入过程。
综合本申请实施例，终端设备可以基于统一的测量模型进行RLM和波束检测，例如，基于统一的测量模型和统一的模型参数进行RLM和波束检测，有利于减少L1采样的复杂度，缩短了RLM的时间，降低了终端设备的复杂度。又例如，基于统一的测量模型和差异化的模型参数进行RLM和波束检测，有利于减少L1采样的复杂度，缩短了RLM的时间，降低了终端设备的复杂度。并且，采用差异化的模型参数，例如不同的计数器配置或定时器配置，有利于避免因配置的用于测量的参考信号集合不具有代表性而导致遗漏监测一些波束的问题，或者，将链路质量不够差的情况误判为小区的 链路失败的问题。
