随着通信技术的发展及需求的丰富，无线通信的应用场景日益广泛，其中比较典型的是车联网(vehicle-to-everything，V2X)，其希望实现车辆与一切可能影响车辆的实体实现信息交互，目的是减少事故发生，减缓交通拥堵，降低环境污染以及提供其他信息服务。根据车辆对端通信节点类型不同，V2X例如可以包含车对车(vehicle-to-vehicle，V2V)、车辆到基础设备(vehicle-to-infrastructure，V2I)、车对网(vehicle-to-network，V2N)以及车对行人(vehicle-to-pedestrian，V2P)。

NR支持3种Sidelink通信模式：单播(Unicast)、组播(Groupcast)和广播(Broadcast)，如下表1所示。
例如，对于单播模式，终端之间可以通过交互PC5-S和PC5-RRC消息来建立、 修改和释放Sidelink单播链路。
为了减少SL场景中，多个终端定位的信令开销较大的问题，本申请实施例的方法，通过第一终端向网络侧设备发送多个第二终端各自的用于定位的测量结果，接收网络侧设备发送的多个第二终端的定位结果，并分别将定位结果转发给对应的第二终端，能够减少终端与网络侧交互的信令开销。
