下面结合附图对本公开所提供的用于终端设备UE到UE中继场景中的目标UE确定方法及其装置进行详细地介绍。
请参见图2，图2是本公开实施例提供的一种用于终端设备UE到UE中继场景中的目标UE确定方法的流程示意图。该方法由第一UE执行。如图2所示，该方法可以包括但不限于以下步骤。
步骤S201：测量第一UE与第二UE之间的信号强度。
其中，在本公开的实施例中，信号强度可以是SD-RSRP(sidelinkdiscovery reference signal receiving power，侧行链路发现参考信号接收功率)或SL-RSRP(sidelink reference signal receiving power，侧行链路参考信号接收功率)，该SD-RSRP为sidelink第二UE发送的发现信号的RSRP，该SL-RSRP为与第二UE的sidelink通信信号的RSRP。
作为一种示例，当第一UE接收到第二UE的发现信号时，第一UE测量与第二UE之间的SD-RSRP。
作为另一种示例，当第一UE已经与第二UE建立侧链路sidelink单播连接时，第一UE测量与第二UE之间的SL-RSRP。
需要说明的是，在本公开的实施例中，第一UE为UE到UE中继场景中的中继UE，第二UE为UE到UE中继场景中的远端UE。
步骤S202：将信号强度满足第一条件的第二UE确定可为目标UE。
可选地，在终端设备UE到UE中继场景中，第一UE可以发送发现信号，该发现信号中携带能够与该第一UE建立侧链路sidelink连接的目标UE的sidelink标识。第二UE收到第一UE发送的发现信号之后，可以根据其中携带的sidelink标识，确定自身是否为与该第一UE建立侧链路sidelink连接的目标UE，从而确定是否选择与该第一UE进行UE到UE中继通信。
可选地，第一UE可以将信号强度满足第一条件的第二UE，确定为可以目标UE，也就是说，第一UE能够将信号强度满足第一条件的第二UE确定为可以建立sidelink连接的目标UE。
在本公开的一些实现方式中，可以将信号强度满足第一条件的第二UE确定为能够通过第一UE的中继功能进行中继通信的目标UE，并与第二UE建立sidelink链接以使第二UE使用第一UE的中继功能进行通信。
在本公开的另一些实现方式中，可以将信号强度满足第一条件的第二UE确定为能够通过第一UE的中继功能进行中继通信的候选目标UE。在第二UE需要通过第一UE进行中继通信时，可以直接与第二UE建立sidelink链接。
通过实施本公开实施例，第一UE可以基于与第二UE之间的信号强度，确定第二UE能否作为目标UE，解决了UE到UE中继场景中中继UE无法确定目标UE的问题。
在本公开的一些实施例中，该信号强度满足第一条件可包括：信号强度满足第一门限的要求；或者，信号强度在第一时间长度内持续满足所述第一门限的要求。可选地，请参见图3，图3是本公开实施例提供的一种用于终端设备UE到UE中继场景中的目标UE确定方法的流程示意图。该方法由第一UE执行。如图3所示，该方法可以包括但不限于以下步骤。
步骤S301：测量第一UE与第二UE之间的信号强度。
在本公开的实施例中，步骤S301可分别采用本公开的各实施例中的任一种方式实现，本公开实施例并不对此作出限定，也不再赘述。例如，可以采用如步骤201中的方式测量测量第一UE与第二UE之间的信号强度，随后不再赘述。
步骤S302：将信号强度满足第一门限的要求，或者信号强度在第一时间长度内持续满足第一门限的要求的第二UE确定可为目标UE。
作为一种示例，将与第一UE之间的信号强度满足第一门限的要求(例如，大于或等于第一门限)的第二UE，确定可以作为目标UE。
作为另一种示例，将与第一UE之间的信号强度满足第一门限的要求的时长，大于或等于第一时间长度的第二UE，确定可以作为目标UE。
在一种可选地实现方式中，第一门限为最低门限，信号强度满足第一门限的要求包括：信号强度大于或等于最低门限；或者，第一门限包括最低门限和最高门限，信号强度满足第一门限的要求包括：信号强度大于或等于最低门限且小于或等于最高门限。
作为一种示例，以第一门限为最低门限为例，将与第一UE之间的信号强度大于或等于第一门限的第二UE，确定可以作为目标UE。
作为另一种示例，以第一门限为最低门限为例，将与第一UE之间的信号强度大于或等于第一门限的持续时长，大于或等于第一时间长度的第二UE，确定可以作为目标UE。
作为又一种示例，以第一门限包括最低门限和最高门限为例，将与第一UE之间的信号强度大于或等于最低门限，并且小于或等于最高门限的第二UE，确定可以作为目标UE。
作为又一种示例，以第一门限包括最低门限和最高门限为例，将与第一UE之间的信号强度大于或等于第一门限并且小于或等于最高门限的持续时长，大于或等于第一时间长度的第二UE，确定可以作为目标UE。
通过实施本公开实施例，第一UE可以基于与第二UE之间的信号强度、第一门限和第一时间长 度，确定第二UE能否作为目标UE，解决了UE到UE中继场景中中继UE无法确定目标UE的问题。
在本公开的一些实施例中，上述用于终端设备UE到UE中继场景中的目标UE确定方法还可以包括：基于第二UE确定第一门限和/或第一时间长度。

在一种可选地实现方式中，上述基于第二UE确定第一门限和/或第一时间长度，可以包括以下步骤：确定门限和/或时间长度与业务之间的对应关系；接收第二UE发送的业务指示信息；根据业务指示信息和对应关系，确定第一门限和/或第一时间长度。
作为一种示例，以基于第二UE确定第一门限为例，预先为不同的业务信息对应设定不同的门限，得到不同业务信息和不同门限的对应关系；第一UE接收第二UE发送的业务指示信息后，确定该业务指示信息指示的业务信息，从而根据该业务信息和上述对应关系，确定该业务信息对应的门限，将该业务信息对应的门限确定为第一门限。
作为另一种示例，以基于第二UE确定第一时间长度为例，预先为不同的业务信息对应设定不同的时间长度，得到不同业务信息和不同时间长度的对应关系；第一UE接收第二UE发送的业务指示信息后，确定该业务指示信息指示的业务信息，从而根据该业务信息和上述对应关系，确定该业务信息对应的时间长度，将该业务信息对应的时间长度确定为第一时间长度。
作为又一种示例，以基于第二UE确定第一门限和第一时间长度为例，预先为不同的业务信息对应设定不同的门限，得到不同业务信息和不同门限的对应关系，并预先为不同的业务信息对应设定不同的时间长度，得到不同业务信息和不同时间长度的对应关系，并且不同的门限对应的业务信息与不同的时间长度对应的业务信息不相同；第一UE接收第二UE发送的用于指示第一门限的业务指示信息，和用于指示第一时间长度的业务指示信息，从而根据上述业务信息和上述对应关系，确定对应的门限和时间长度，将上述业务信息对应的门限确定为第一门限，并将上述业务信息对应的时间长度确定为第一时间长度。
作为又一种示例，预先为每种业务信息设定对应的门限和时间长度，并且不同业务信息对应的门限和时间长度不同，从而得到不同业务信息与不同门限和时间长度的对应关系；第一UE接收第二UE发送的业务指示信息，确定该业务指示信息指示的业务信息，从而根据该业务信息和上述对应关系，确定该业务信息对应的门限和时间长度，将该业务信息对应的门限确定为第一门限，并将该业务信息对应的时间长度确定为第一时间长度。
需要说明的是，在本公开的实施例中，业务指示信息可以是RSC(relay servicecode，中继业务代码)。
可选地，上述门限和/或时间长度与业务之间的对应关系可以由网络侧设备、高层与应用层中的至少一方提供。

步骤S402：将信号强度满足第一条件的第二UE确定可为目标UE。
在本公开的实施例中，步骤S402可分别采用本公开的各实施例中的任一种方式实现，本公开实施例并不对此作出限定，也不再赘述。
步骤S403：在发现信号中携带目标UE的标识信息和/或目标UE的测量结果。
其中，该标识信息可以包括能够与第一UE建立sidelink连接的目标UE的sidelink标识。当该发现信号携带标识信息时，远端UE收到中继UE的发现信号之后，根据其中携带的UE标识，确定自身是否为目标UE，从而决定是否选择第一UE作为中继UE进行UE到UE中继通信。
作为一种示例，第一UE在发送的发现信号中携带目标UE的标识信息。
作为另一种示例，第一UE在发送的发现信号中携带目标UE的测量结果。
作为又一种示例，第一UE在发送的发现信号中携带目标UE的标识信息和目标UE的测量结果。
在本公开实施例的一种可选地实现方式中，上述测量结果为强弱指示信息；上述方法还可以包括 以下步骤：将第一UE与目标UE间的信号强度，和第二门限进行大小比较；根据第一UE与目标UE间的信号强度和第二门限的比较结果，确定目标UE的强弱指示信息。
举例而言，第一UE将与目标UE间的信号强度和第二门限进行大小比较得到比较结果；响应于比较结果为与目标UE间的信号强度大于或等于第二门限，确定目标UE的强弱指示信息为强指示信息；或者，响应于比较结果为与目标UE间的信号强度小于第二门限，确定目标UE的强弱指示信息为弱指示信息。
可选地，上述在发现信号中携带目标UE的标识信息可以包括：按照目标UE的强弱指示信息，将目标UE的标识信息携带在发现信号之中对应的列表中。
举例而言，预先为不同的强弱指示信息设置对应的不同列表，根据得到的目标UE的强弱指示信息，确定该目标UE的强弱指示信息对应的列表，将该目标UE的标识信息携带在该目标UE的强弱指示信息对应的列表中。
可选地，上述第二门限可以由网络侧设备、高层、应用层和目标UE中的至少一方提供。
