具体实施方式
这里将详细地对示例性实施例进行说明，其示例表示在附图中。下面的描述涉及附图时，除非另有表示，不同附图中的相同数字表示相同或相似的要素。以下示例性实施例中所描述的实施方式并不代表与本公开相一致的所有实施方式。相反，它们仅是与如所附权利要求书中所详述的、本公开的一些方面相一致的装置和方法的例子。
在本公开实施例使用的术语是仅仅出于描述特定实施例的目的，而非旨在限制本公开实施例。在本公开实施例和所附权利要求书中所使用的单数形式的“一种”和“该”也旨在包括多数形式，除非上下文清楚地表示其他含义。还应当理解，本文中使用的术语“和/或”是指并包含一个或多个相关联的列出项目的任何或所有可能组合。

侧链通信(sidelink，SL)：两个终端设备之间的直连通信方式，两个终端设备之间接口为PC-5，其中，sidelink通信支持三种传输方式，单播，组播和广播。
请参考图2，图2本申请实施例提供的信道测量方法的流程示意图。该信道测量方法由第一设备执行，如图2所示，该方法包括但不限于下述步骤：
S201，对候选中继设备进行信道测量，以获取候选中继设备的第一信道测量结果。
可选地，候选中继设备包括设备到网络(UE to NW，U2N)中继场景下的中继设备和设备到设备(UEto UE，U2U)中继场景下的中继设备。候选中继设备可以为一个，也可以为多个。
在U2N中继场景下，第一设备可以不直接与基站连接而通过另外一个中继设备实现与基站的通信，其中与基站没有连接的第一设备称为远端设备。例如，UE A可以不直接与基站连接而通过另外一个UEB的中继实现与基站的通信，其中与基站没有连接的UEA称为远端UE(remote UE)，而提供中继功能的UE B称为中继UE(relay UE)，远端UE与中继UE之间通过sidelink单播通信。其中，UE直接与基站连接称为直接链路，UE通过中继UE与基站连接称为间接链路。
在U2U中继场景下，第一设备可以通过sidelink与另一个设备进行通信，也可以通过中继设备实现两个设备之间的通信。例如，UE A可以不直接与UE B连接，而是通过UE C的中继实现与UE B的连接。其中UE A与UE C为远端UE，提供中继功能的UE B为中继UE，所有UE之间通过sidelink单播 通信。其中，UE A直接与UE B保持单播连接时称为sidelink直接链路，UE A通过中继UE与UE B保持单播连接时称为sidelink间接链路。
第一设备在上述两种场景下的工作过程中，随着第一设备的移动或者网络情况的变化，可能会有对应第一设备来说信道情况更好的候选中继设备。第一设备可以对候选中继进行信道测量，以获取候选中继设备对应的第一测量结果。
可选地，第一测量结果可以反映第一设备与候选中继设备间的信道质量。可选地，第一信道测量结果可以包括以下参数中的至少一种：SL通信信号的RSRP和SL发现信号的RSRP。
S202，第一信道测量结果满足设定事件，将第一测量结果上报给第二设备和/或进行链路切换。
为了实现第一设备可以从工作的间接链路或者Sidelink直接链路，切换到更好的候选中继设备提供的链路，本申请实施例中，预先设定事件，通过该设定事件判断是否对第一测量结果进行上报，和/或判断是否进行链路切换，当进行链路切换时，可以不上报测量结果，也可以上报测量结果。可选地，设定事件可以基于协议约定或者网络配置或者预定义的方式确定。
在满足第一信道测量结果满足设定事件的情况下，说明候选中继设备的信道质量较好，此时为了提高通信的稳定性或者信息传输的安全性，作为一种可能的实现方式，第一设备向第二设备上报第一测量结果，以便于由第二设备判断是否进行链路切换。
在一些实现中，第一设备工作在间接链路的情况下，第二设备为网络设备，第一设备可以将第一测量结果上报给网络设备。可选地，第一设备通过无线资源控制(Radio Resource Control，RRC)消息向网络设备上报该第一信道测量结果。
在另一些实现中，第一设备工作在sidelink直连链路的情况下，对端设备为第二设备，第一设备可以将第一测量结果上报给对端设备。可选地，第一设备通过SL RRC消息向对端设备上报第一信道测量结果。可选地，对端设备还可以向网络设备上报第一信道测量结果。
可选地，由第一设备触发进行链路切换。本申请实施例中，满足设定条件的候选中继设备可以称为目标中继设备，可以用于为第一设备提供中继服务。在一些实现中，第一设备工作在间接链路的情况下，第一设备可以从当前工作的第一间接链路切换至包括目标中继设备的另一个第二间接链路。第一设备可以从服务中继设备切换至目标中继设备，通过目标中继设备与网络设备继续通信。在另一些实现中，第一设备工作在sidelink直连链路的情况下，第一设备与对端设备不再直接连接，而是通过目标中继设备的中继，与对端设备进行连接。也就是说，第一设备从当前工作的SL直连链路切换至包括目标中继设备的SL间接链路。
例如，第一设备(UE A)可以与第二设备(UEB)通过SL单播方式连接，在确定出目标中继设备UE C后，可以进行链路切换，即UE A不再与UE B直接连接，而是通过UE C进行连接，即将SL直连链路，切换至包括UE C的SL间接链路。
再例如，第一设备(UEA)可以通过服务中继设备(UE D)与网络设备(基站)连接，在确定出目标中继设备UE C后，可以进行链路切换，即UE A不再通过UE D与基站连接，而是通过UE C与基站连接。
作为又一种可能的实现方式，第一设备在进行链路切换的同时，向第二设备上报第一测量结果。
本申请实施例中，可以对候选中继设备进行信道测量，并通过设定事件进行上报或切换的触发判断，通过信道测量可以确定出更适合提供中继服务的中继设备，而且可以通过上报或主动链路切换，能够实 现中继设备间的切换，即间接链路间的切换，还可以实现直连链路到包括中继设备的间接链路的切换，增强了设备的切换链路的模式。
请参考图3，图3本申请实施例提供的信道测量方法的流程示意图。该信道测量方法由第一设备执行，如图3所示，该方法包括但不限于下述步骤：
S301，对候选中继设备进行信道测量，以获取候选中继设备的第一信道测量结果。
关于步骤S301的具体介绍，可参见上述实施例中相关内容的记载，此处不再赘述。
S302，对第三设备进行信道测量，以获取第三设备的第二信道测量结果。
其中，第三设备包括以下类型中的一种：服务第一设备的中继设备、与第一设备之间SL单播连接的设备。在一些实现中，第一设备工作在间接链路的情况下，第三设备可以服务第一设备的中继设备。在另一些实现中，第一设备工作在sidelink直连链路的情况下，第三设备是与第一设备之间SL单播的对端设备。
可选地，第二测量结果可以反映第一设备与第三设备间的信道质量。可选地，第二信道测量结果可以包括以下参数中的至少一种：SL通信信号的RSRP(SL-RSRP)和SL发现信号的RSRP(SD-RSRP)。
可选地，第一设备可以通过SL设备标识和/或设备特征，确定第三设备，其中，设备特征包括以下特征中一种：服务中继设备或主要服务中继设备或辅助服务中继设备。第一设备可以接收第三设备发送的配置信令，在该配置信令中携带SL设备标识和/或设备特征。
S303，若第一信道测量结果大于或者等于第一门限值，且第二信道测量结果小于第二门限值，则确定第一信道测量结果满足设定事件。
可选地，可以预先设置第一门限值和第二门限值。其中，第一门限值和第二门限值由以下方式中的一种确定：协议约定、网络配置、预定义或预配置。本公开对此不作限定
可选地，第一门限值和第二门限值可以在信道测量的配置过程同步配置给第一设备，也可以独立于信道测量的配置过程进行配置。
本申请实施例中，第一测量结果和第二测量结果包括测量目标的各自的测量值。其中，测量目标可以包括SL通信信号和SL发现信号。
可以将第一测量结果中每个测量目标的第一测量值与各自的第一门限值进行比较。进一步地，可以将第二测量结果中每个测量目标的第二测量值与各自的第二门限值进行比较。
一些实现中，当每个测量目标均满足设定事件时，则可以确定第一信道测量结果满足设定事件。也就是说，第一测量结果中每个测量目标的第一测量值均大于或者等于第一门限值，且第二测量结果中每个测量目标的第二测量值均小于第二门限值，则可以确定第一信道测量结果满足设定事件。
另一些实现中，当部分测量目标满足设定事件时，例如，80％的测量目标的测量值满足设定事件，则可以确定第一信道测量结果满足设定事件。也就是说，第一测量结果中80％的测量目标的第一测量值大于或者等于第一门限值，且第二测量结果中80％的测量目标的第二测量值小于第二门限值，则可以确定第一信道测量结果满足设定事件。
S304，将第一测量结果上报给第二设备和/或进行链路切换。
作为一种可能的实现方式，第一设备向第二设备上报第一测量结果，以便于由第二设备判断是否进行链路切换。
在一些实现中，第一设备工作在间接链路的情况下，第二设备为网络设备，第一设备可以将第一测 量结果上报给网络设备。可选地，第一设备通过RRC消息向网络设备上报该第一信道测量结果。
在另一些实现中，第一设备工作在sidelink直连链路的情况下，对端设备为第二设备，第一设备可以将第一测量结果上报给对端设备。可选地，第一设备通过SL RRC消息发送向对端设备上报第一信道测量结果。可选地，对端设备还可以向网络设备上报第一信道测量结果。
作为另一种可能的实现方式，由第一设备触发进行链路切换。在一些实现中，第一设备工作在间接链路的情况下，第一设备可以从当前工作的间接链路切换至包括候选中继设备的另一间接链路。第一设备可以从服务中继设备切换至满足设定条件的候选中继设备，通过候选中继设备与网络设备继续通信。在另一些实现中，第一设备工作在sidelink直连链路的情况下，第一设备与对端设备不再直接连接，而是通过满足设定事件的候选中继设备的中继，与对端设备进行连接。
作为另一种可能的实现方式，第一设备在进行链路切换的同时，向第二设备上报第一测量结果。
可选地，第一测量结果包括以下一种或多种：
候选中继设备的第一测量结果；
