下面参考附图对本公开提供的测距方法、装置、UE及存储介质进行详细描述。
图1为本公开实施例所提供的一种测距方法的流程示意图，应用于测距UE中，如图1所示，测距方法可以包括以下步骤：
步骤101，测距UE(User Equipment，终端设备)接收测距发起UE发送的测距服务请求，其中，测距服务请求包括标识和测距参数。
需要说明的是，本公开实施例的测距方法可以应用在任意的UE中。UE可以是指向用户提供语音和/或数据连通性的设备。UE可以经RAN(Radio Access Network，无线接入网)与一个或多个核心网进行通信，UE可以是物联网终端，如传感器设备、移动电话(或称为“蜂窝”电话)和具有物联网终端的计算机，例如，可以是固定式、便携式、袖珍式、手持式、计算机内置的或者车载的装置。例如，站(Station，STA)、订户单元(subscriber unit)、订户站(subscriber station)，移动站(mobile station)、移动台(mobile)、远程站(remote station)、接入点、远程终端(remoteterminal)、接入终端(access terminal)、用户装置(user terminal)或用户代理(useragent)。或者，UE也可以是无人飞行器的设备。或者，UE也可以是车载设备，比如，可以是具有无线通信功能的行车电脑，或者是外接行车电脑的无线终端。或者，UE也可以是路边设备，比如，可以是具有无线通信功能的路灯、信号灯或者其它路边设备等。
其中，测距参数可以包括测距内容(例如观察UE与目标UE之间的距离值、角度值、目标UE到观察UE的方向等)、QoS(Quality of Service，服务质量)要求、以及报告周期性等。在本公开一个实施例之中，测距服务请求的标识可以包括观察UE的标识和目标UE的标识，其中，观察UE可以为用于执行测距操作的UE，观察UE用于对目标UE进行测距。在本公开的一个实施例之中，观察UE可以基于测距参数对目标UE进行测距以生成测距结果。当然在本公开的其他实施例之中，测距服务请求的标识可以仅包括观察UE的标识或目标UE的标识。例如，如果测距服务请求只发给观察UE，则测距服务请求的标识可以仅包括目标UE的标识，使得观察UE可以根据目标UE的标识确定目标UE。
作为一种示例，图2为本公开实施例所提供的一种观察UE与目标UE相对位置的结构示意图，如图2所示，观察UE具有参考平面和参考方向。以及，目标UE到观察UE的方向可以是从观察UE和目标UE的连线指向参考方向的方向，也即是，图2所示的方向A。其中，目标UE到观察UE的方向可以由目标UE的方位角方向和高程方向表示，参考图2可知，目标UE的方位角方向是从参考方向指向与从观察者UE到目标UE的线投影在与正交于天顶的参考方向相同的平面上的线之间形成的角度。以及，目标UE还具备仰角方向，仰角方向为从水平面指向观察UE与目标UE的连线的方向。
则观察UE通过测量图2所示的目标UE与观察UE之间的距离和目标UE到观察UE的方向即可实现对目标UE的测距。并且，测距服务无论有无5G覆盖都可以进行。
进一步地，在本公开的一个实施例中，测距发起UE可以为观察UE。在本公开的另一个实施例中，测距发起UE可以为目标UE。在本公开的再一个实施例中，测距发起UE可以不为目标UE和观察UE中的任一个。
