为了更好地理解本公开任一个实施例所描述的技术方案，首先，对相关技术中的应用场景进行说明：
在一个实施例中，波束失败探测(BFD，Beam Failure Detection)包括：检测对象是终端当前的服务波束(特殊小区和辅助小区)的激活带宽部分(BWP，Bandwidth Part)上配置的BFD参考信号资源集(BFD RS set),该资源集可以是同步信号块参考信号SSB-RS和/或信道状态信息参考信号CSI-RS，在评估周期TEvaluate_BFD内的测量结果与Qout_LR(块误码率BLER＝10％)门限比较，如果所有测量结果都低于门限，则触发一次波束失败实例指示(Beam Failure Instance Indication)，同时波束失败探测定时器(beamFailureDetectionTimer)开始运行。
在一个实施例中，在配置的beamFailureDetectionTimer超时之前，如果Beam Failure Instance Indication数量达到配置门限beamFailureInstanceMaxCount，终端声明波束失败，启动候选波束探测 (CBD，Candidate Beam Detection)。
在一个实施例中，候选波束探测(CBD，Candidate Beam Detection)包括：检测对象是网络给终端配置的候选波束集，测量内容是对应候选波束的SSB-RS和/或CSI-RS，检测依据是在评估周期TEvaluate_CBD内测量结果与配置门限Qin_LR(L1-RSRP)的比较，将候选波束中测量结果高于门限的，作为可用的新波束。终端通知网络找到的可用的新波束，以便网络知道能够使用该新波束进行下行传输。
在一个实施例中，引入了对于BFD的放松机制。即对于满足放松准则(低移动性和/或信道状态好)的用户，将进行BFD放松机制。例如，可以将终端周期性测量每个对应服务波束的周期拉长等。
在一个实施例中，放松准则(低移动性和/或信道状态好)可以通过协议约定，将准则涉及到的参数通过测量触发事件方式下发：
低移动性准则：下发参数包括TsearchDeltaP和SsearchDeltaP；判断标准包括参考信号的L3-RSRP；
小区信号质量好准则：下发参数包括偏移量Offset；判断标准包括参考信号的L1-SINR。
针对低移动性准则，在一定时间内(T SearchDeltaP)，若参考的接收信号质量与终端当前的RSRP的差值小于某预设门限值(S SearchDeltaP)，即代表信号变化幅度不大，则可认为当前终端处于低移动性状态。值得注意的是，该判决仅在信号下降时才需要进行考虑，具体判决条件如下：
低移动性准则的进入条件包括：
(Srxlev Ref–Srxlev)<S SearchDeltaP；
其中：
Srxlev＝当前服务小区的Srxlev，单位为dB；
Srxlev Ref＝当前服务小区的Srxlev参考值，单位为dB。根据如下方式进行设置：
1、终端切换到了一个新小区；
2、Srxlev-Srxlev Ref>0；
3、在T SearchDeltaP内没有满足判决条件；
在满足上述任一条件时,UE将Srxlev Ref设为当前的服务小区的Srxlev。
低移动性准则的退出条件：不满足进入条件则退出。
针对小区信号质量好准则，一个小区若配置了多个参考信号，对每个参考信号的信号与干扰加噪声比(SINR，Signal to Interference plus Noise Ratio)值与阈值进行比较，任意参考信号满足进入条件，则认为该小区满足小区信号质量好准则，若终端计时器beamFailureDetectionTimer正在运行，或者终端接收到非连续接收(DRX,Discontinuous Reception)配置发生变化(由配置了DRX变成不配置DRX，或者DRX周期配置为＞80ms)，则认为该小区不满足小区信号质量好准则。
小区信号质量好的进入条件包括：
全部的参考信号RS,都满足SINR measured＞ Qout+Offset；
小区信号质量好的退出条件包括：
UE端计时器beamFailureDetectionTimer正在运行。
针对同时配置低移动性准则(R1事件)和小区信号质量好准则(R2事件)，进入条件包括：
进入条件为同时满足两个准则的进入条件，
即R1事件的进入条件和R2事件的进入条件同时满足；
退出条件包括：
离开条件为任意一个准则满足离开条件，或者两个都不满足才退出；
即：
满足R1事件的退出条件，或者
满足R2事件的退出条件同时满足，或者
同时满足R1事件和R2事件的退出条件。
以上测量触发事件，可以触发终端上报是满足进入还是离开事件，其通知网络的方式可以是通过用户辅助信息(UAI，User Assistance Information)。对于UAI的配置和上报是基于以小区为单位上报的。此时用了一个bitmap，每个bit对应了一个小区。其中，取值为1意味着终端在执行放松，而取值为0，则意味着没有在放松。
可以理解的是，上述小区信号质量好准则和低移动性准则均为移动通信和无线通信领域常见名词，具备清楚明确的含义。
在一个实施例中，mTRP的增强，终端可以同时连接到两个TRP，网络可以以TRP为单位给终端配置用于波束失败检测的资源，每个BFD参考资源集对应一个TRP，即BFD RS set。对于需要波束失败检测的小区，网络侧可以配置2个BFD RS Set。每个BFD RS Set可以包括1个或多个BFD RS。
但是，在mTRP引入之后，此时将存在2个资源集合(BFD-RS sets)，因此，需要考虑在mTRP场景下的如何判断BFD放松状态。

为了更好地理解本公开实施例，以下通过一个实施例性实施例对本公开技术方案进行进一步说明：
本公开实施例提供一种mTRP场景下终端判断BFD放松状态的方法：
在一个实施例中，终端基于低移动性准则和小区信号质量好准则判断BFD放松状态；
在一个实施例中，对于小区信号质量好准则，可以采用per BFD-RS set的判断方法：
1、进入条件：该BFD-RS set内至少存在一个BFD RS满足小区信号质量好准则；
2、退出条件：
2.1、该BFD-RS set对应的beamFailureDetectionTimer正在运行，或者，
2.2、UE接收到DRX配置发生变化：由配置了DRX变成不配置DRX，或者DRX周
期配置为＞80ms。
在一个实施例中，对于小区信号质量好准则，也可以采用per cell的判断方法：
1、进入条件：
1.1、UE连接的两个BFD RS set中，任意存在一个BFD RS满足小区信号质量好准则，或者，
1.2、UE连接的两个BFD RS set中，分别存在一个BFD RS满足小区信号质量好准则。
2、退出条件：
2.1、两个BFD RS set分别对应的beamFailureDetectionTimer均正在运行，或者，
2.2、两个BFD-RS set其中一个对应的beamFailureDetectionTimer正在运行，或者
2.3、UE接收到DRX配置发生变化：由配置了DRX变成不配置DRX，或者DRX周期配置为＞80ms。
在一个实施例中，对于mTRP的BFD放松，小区信号质量好准则对应的offset可以单独配置。
在一个实施例中，利用扩展的offset信息域来指示第二个BFD-RS set的配置(即原来的IE用于指示第一个BFD-RS set的配置)。
在一个实施例中，对于低移动性准则，基于per UE的方法判断UE的移动性，若PCell满足基于L3 RSRP的低移动性准则则认为该UE处于低移动性，即此UE的所有serving cell均满足低移动性准则。
在一个实施例中，若UE同时配置了低移动性和小区信号质量好准则，则同时满足两种准则时，才可以执行per BFD RS set或者per Cell的BFD放松；若UE只配置了小区信号质量好准则，则根据小区信号质量好准则，判断是否可以执行per BFD RS set或者per Cell的BFD放松。
在一个实施例中，使用放松系数，扩展BFD对应的评估周期；这里，该放松系数可以由协议约定，该放松系数也可以是网络可配的。
在一个实施例中，对于per BFD set的放松，可以per set配置放松系数。
