为了方便理解，以下对本申请实施例涉及的一些内容进行说明：
一、反向散射通信。
反向散射通信是指反向散射通信设备利用其它设备或者环境中的射频信号进行信号调制来传输自己信息，是一种比较典型的无源物联设备。
二、单基地反向散射通信系统(Monostatic Backscatter Communication System,MBCSs)。
如图2所示为MBCS，比如传统的射频识别(Radio Frequency Identification，RFID)系统就是典型的MBCS，系统中包含BSC发送端(比如标签(Tag))和读写器(Reader)。读写器中包含无线电频率(Radio Frequency，RF)射频源和BSC接收端，其中RF射频源用于产生RF射频信号从而来给BSC发送端/Tag供能。BSC发送端通过反向散射经过调制后的RF射频信号，Reader中的BSC接收端接收到该反向散射信号后进行信号解调。由于RF射频源和BSC接收端是在同一个设备中，比如这里的Reader，因此成为单站反向散射通信系统。MBCSs系统中，由于从BSC发送端发送出去的RF射频信号会经过往返信号的信号衰减引起的双倍远近效应，因而信号的能量衰减大，因而MBCS系统一般用于短距离的反向散射通信，比如传统的RFID应用。
三、双基地反向散射通信系统(Bistatic Backscatter Communication Systems,BBCSs)。
不同于MBCS，BBCS中的RF射频源、BSC发送设备和BSC接收设备是分开的，如图3所示为BBCS系统的示意图。因而，BBCS避免了往返信号衰减大的问题，另外通过合理的放置RF射频源的位置可以进一步提高BBCS通信系统的性能。值得注意，环境反向散射通信系统(Ambient Backscatter Communications Systems，ABCSs)也是双基地反向散射通信的一种，但与BBCS系统中的射频源为专用的信号射频源，ABCS系统中的射频源可以是可用的环境早的射频源，比如：电视塔、蜂窝基站、WiFi信号、蓝牙信号等。
四、反向散射通信中的覆盖。
受限于网络节点的发送功率、双程链路衰减、储能电路的储能效率与储能容量、反向散射通信设备的接收灵敏度、收发天线增益以及信号干扰的影响，反向散射通信的前向和反向覆盖都面临较大的技术挑战。具体地，对于从网络节点到反向散射通信设备的前向链路中，由于驱动能量采集电路工作需要几uW到几十uW能量，因此反向散射通信设备接收用于供能的射频信号的信号强度或灵敏度大约为-20dBm左右，而传统终端设备的接收机灵敏度为-100dBm左右。如果反向散射通信设备具备储能能力的话，则其接收用于供能的射频信号的接收灵敏度可以放松至-30dBm。另外，考虑到能量采集电路的特性，即输入信号的功率越低能量转化效率也会越低，因此当输入的射频信号功率低于-23dBm的情况下，能量采集电路很难有效的采集信号并整流成可用的直流电压。另一方面，从反向散射通信设备到网络节点的反向链路中，由于部分信号能量被用于供能，因此反向散射的信号强度比入射供能信号的信号强度低3dB～5dB。另外，低硬件成本反向散射通信设备的天线增益一般也不会太大，大约为0dBi～2dBi。
采用分离式架构(即双基地反向散射通信系统)以及集成低功耗放大器都是提升反向散射通信覆盖的有效方式。除此之外，通过使用多输入多输出(Multiple Input Multiple Output，MIMO)波束成形技术可以使得射频信号的能量更集中，并结合高能量转化效率的能量采集电路，也可以有效的改善反向散射通信覆盖的问题。在满足反向散射设备能量采集最大化的约束条件下，结合射频源混合波束成形以及反向散射设备中被动式波束成形的收发端联合波束成形方案，可有效增强前向覆盖。
相关技术中，波束传输主要是为通信业务设计的，因此在波束测量过程中，是以参考信号的层1参考信号接收功率(Layer 1 reference signal received power，L1-RSRP)、层1信干噪比(Layer 1signal-to-noise and interference ratio，L1-SINR)等参量作为波束测量和波束选择的信号质量评估准则的。然而在反向散射通信等需要射频能量的系统中，由于反向散射通信设备需要依赖于其它设备的射频信号供能才能进行数据传输，并且受到反向散射通信设备接收灵敏度的影响，反向散射通信设备的接收供能信号的灵敏度约为-20dBm～-30dBm，而接收通信数据的灵敏度约为-50dBm～-60dBm，因此射频供能成为制约反向散射通信传输距离的瓶颈。与NR中的基于定向波束进行传输相同，供能设备也可以采用定向波束进行波束赋形beamforming传能，从而提高反向散射通信设备的能量转化效率与射频供能覆盖受限的问题。但不同于NR系统中采用通信信号的L1-RSRP、L1-SINR等参量作为波束测量和波束选择的信号质量评估准则，基于能量传输的能量波束不需要考虑选择的波束的信号质量最优，而只需要考虑选择的能量赋形波束能够提供功率最强的能量供应。更进一步，受限于储能能力与能量转化效率，基于射频能量采集的UE设备的上行同样也存在通信覆盖的问题。为了提升覆盖距离，接收端也可以采用波束赋形技术来获得波束赋形增益，从而提升通信覆盖。
相关技术的波束训练方法大多是针对于单基地架构下的波束训练，即提供下行发送 波束的设备与提供上行接收波束的设备是同一个设备，比如基站设备等。但针对于双基地架构，提供下行发送波束的设备、提供上行接收波束的设备以及接收下行发送波束的设备是不同的设备，从而产生了级联信道下的波束训练问题。以图4为例，提供下行能量发送波束的设备(即第三设备)是UE，提供上行接收波束的设备(即第一设备)是基站设备，接收下行发送波束的设备(即第二设备)是需要供能的UE设备或BSC设备，这样第一设备-第二设备-第三设备构成了级联链路。由于第一设备与第三设备不是同一个设备，因此第一设备与第三设备需要进行信令交互以最终确定具有最好波束赋形增益的收发波束。为此，提出本申请的级联链路中的信号测量处理方法。值得指出，除了反向散射通信，一些不适用电池供电或者更换电池成本高的终端设备也可以基于射频能量进行供能。此类设备可以基于网络节点的无线射频能量进行能量收割与能量存储，并且利用收割到的能量自主生成载波信号来进行通信传输。因此本申请的级联链路中的信号测量处理方法同样适用于第二设备具有自主生成载波能力的场景。
下面结合附图，通过一些实施例及其应用场景对本申请实施例提供的级联链路中的信号测量处理方法进行详细地说明。
参照图5，本申请实施例提供了一种级联链路中的信号测量处理方法，如图5所示，该级联链路中的信号测量处理方法，包括：

步骤502，所述第一设备执行第一操作；
其中，所述第一操作包括以下任一项：
