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申请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、本申请的一些方面相一致的装置和方法的例子。
图1示出了本申请一个示意性实施例提供的通信系统的架构示意图。如图1所示，该系统架构可以包括：用户设备(User Equipment，UE)、下一代无线接入网(Next Generation-Radio Access Network，NG-RAN)、位置管理功能(Location Management Function，LMF)、接入和移动性管理功能(Access and Mobility Management Function，AMF)、增强的服务移动位置中心(Enhanced-Service Mobile Location  Center，E-SMLC)、服务定位协议(Service Location Protocol，SLP)。
UE：是移动用户与网络交互的入口，能够提供基本的计算能力、存储能力，向用户显示业务窗口，接受用户操作输入。UE会采用下一代空口技术，与NG-RAN建立信号连接、数据连接，从而传输控制信号和业务数据到移动网络。UE之间可以通过PC5接口实现侧行链路上的链接。不同UE之间可以通过PC5接口实现侧行链路上的链接和通信。比如，UE1和UE2之间通过基于PC5接口的侧行链路进行通信。
NG-RAN：包括升级后的4G基站(next generation-evolved Node B，ng-eNB)和5G基站(next generation-NodeB，gNB)。其中，ng-eNB是NG-RAN的网络元件，其可以提供用于位置估计的测量结果，并且针对目标UE进行无线信号的测量，并将这些测量结果传送给LMF。ng-eNB响应于来自LMF的请求(按需或定期)进行其测量。ng-eNB可以服务多个TP，包括例如远程无线头和仅定位参考信号(Positioning Reference Signal，PRS)用于演进的通用地面无线接入网(Evolving-Universal Terrestrial Radio Access，E-UTRA)的基于PRS的地面信标系统定位。gNB是NG-RAN的网络元件，其可以为目标UE提供测量信息并将该信息传送给LMF。需要说明的是，gNB和ng-eNB可能不总是都存在。当gNB和ng-eNB都存在时，NG-C接口仅存在其中一个。UE与gNB之间通过新空口-用户设备(New Radio-User equipment，NR-Uu)接口连接，其中，NR-Uu接口是具有对NG-RAN的NR接入的目标UE的LTE定位协议的若干传输链路之一。UE与ng-eNB之间通过长期演进-用户设备(Long Term Evolution-User equipment，LTE-Uu)接口连接，其中，LTE-Uu接口是LTE定位协议的若干传输链路之一。
LMF：用于管理针对目标UE的不同位置服务的支持，包括UE的定位和向UE的辅助数据的递送。LMF可以与服务gNB或服务ng-eNB交互以用于目标UE，以便获得UE的位置测量，包括由ng-eNB进行的上行链路测量和由UE提供给ng-eNB的下行链路测量。基站(evolved Node B，eNB)作为其他功能的一部分，例如用于支持切换。LMF可以与目标UE交互，以便在请求特定位置服务时传送辅助数据，或者如果请求则获得位置估计。
AMF：用于从另一实体接收对与特定目标UE相关联的一些位置服务的请求，或者AMF本身决定代表特定目标UE发起一些位置服务(例如，用于来自该特定目标UE的IMS紧急呼叫)。然后，AMF向LMF发送位置服务请求。LMF处理位置服务请求，其可以包括将辅助数据传送到目标UE以辅助基于UE和/或UE辅助的定位和/或可以包括目标UE的定位。然后，LMF将位置服务的结果返回给AMF请求的位置服务的情况下，AMF返回位置服务结果到此实体。
E-SMLC：用于定位UE的位置。
SLP：是负责在用户平面上定位的安全用户平面(Secure user plane，SUPL)实体。

第一参考信号是侧行链路的定位参考信号。第一参考信号是用于侧行链路的定位参考信号或位置参考信号，或者说，第一参考信号是用于在侧行链路场景下对目标终端进行定位的参考信号。第一参考信号用于确定目标终端的位置信息和/或目标终端的距离信息。该位置信息包括绝对位置或相对位置。

在步骤203中：第一终端根据第一参考信号对目标终端进行定位。
可选地，第一终端采用基于时间差进行定位的定位技术，根据第一参考信号对目标终端进行定位。示例性的，时间差是指不同位置的第二终端发送的参考信号的时间差，或者，同一位置的第二终端的参考信号的收发时间差。
可选地，第一终端采用基于角度进行定位的定位技术，根据第一参考信号对目标终端进行定位。该角度是第一参考信号的发送角度或接收角度。
