为了便于本领域内技术人员理解，本公开实施例列举了多个实施方式以对本公开实施例的技术方案进行清晰地说明。当然，本领域内技术人员可以理解，本公开实施例提供的多个实施例，可以被单独执行，也可以与本公开实施例中其他实施例的方法结合后一起被执行，还可以单独或结合后与其他相关技术中的一些方法一起被执行；本公开实施例并不对此作出限定。
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，对波束失败检测(BFD，Beam Failure Detection)的应用场景进行说明：
在一个实施例中，针对主小区(Pcell，Primary Cell)、辅主小区(PSCell，Primary Secondary Cell)和辅小区(Scell，Secondary Cell)设计了BFD机制。终端对物理下行控制信道(PDCCH，Physical Downlink Control Channel)进行测量，确定下行发送波束对应的链路质量；如果对应的链路质量小于质量阈值，则认为下行发送波束发生波束失败。
在一个实施例中，终端周期性地测量用于波束失败检测的周期性信道状态信息参考信号(CSI-RS，Channel State Information Reference Signal)。测量结果是CSI-RS的信号与干扰加噪声比(SINR,Signal to Interference plus Noise Ratio)值，将SINR对应的块误码率(BLER，Block Error Ratio)值与门限Q out_LR进行比较，确定服务波束质量。物理层将结果上报媒体接入控制(MAC，Media Access Control)层。
在一个实施例中，在评估周期T Evaluate_BFD内评估测量结果是否低于阈值Q out_LR，如果所有测量结果都低于Q out_LR，则触发一次物理层向MAC层上报波束失败实例指示(BFI，Beam Failure Indication)。
在一个实施例中，定义指示间隔T indication-BFD，在每T indication-BFD时间内，终端都会触发一次物理层向MAC层上报BFI。
在一个实施例中，MAC层维护相关的波束失败检测定时器(BFD timer，beamFailureDetectionTimer)和波束失败计数器BFI_counter。当MAC层收到一次BFI，则启动BFD timer；同时BFI_counter进行加1计数，如果BFD timer超时，则BFI_counter会被重置为0。若在BFD timer运行期间BFI_counter达到规定的 最大值(beamFailureInstanceMaxCount)，则终端确定发生波束失败。
这里，上述方案并未考虑终端的功耗问题，当终端满足某些条件时，终端可以放松BFD的测量行为，从而节省终端用电。
如图2所示，本实施例中提供一种放松测量的方法，其中，该方法被终端执行，该方法，包括：

在一个实施例中，宽松度，可以是用于表征参考信号在数量上的放松程度。例如，第一放松方式对应的测量的参考信号的数量为10个；第二放松方式对应的测量的参考信号的数量为20个，则基于第二放松方式进行放松测量的宽松度为基于第一放松方式进行放松测量的宽松度的1/2倍。
在一个实施例中，宽松度，可以是用于表征频域范围的放松程度。例如，第一放松方式对应的频域范围为BWP1；第二放松方式对应的频域范围为BWP2，BWP1为BWP2的1/2。则基于第二放松方式进行放松测量的宽松度为基于第一放松方式进行放松测量的宽松度的1/2倍。
