请参考图1，其示出了本公开实施例提供的一种无线通信系统的结构示意图。如图1所示，无线通信系统是基于蜂窝移动通信技术的通信系统，该无线通信系统可以包括：若干个终端11以及若干个基站12。

基站12可以是无线通信系统中的网络侧设备。其中，该无线通信系统可以是第四代移动通信技术(the 4th generation mobile communication，4G)系统，又称长期演进(Long Term Evolution，LTE)系统；或者，该无线通信系统也可以是5G系统，又称新空口(new radio，NR)系统或5G NR系统。或者，该无线通信系统也可以是5G系统的再下一代系统。其中，5G系统中的接入网可以称为NG-RAN(New Generation-Radio Access Network，新一代无线接入网)。或者，MTC系统。
其中，基站12可以是4G系统中采用的演进型基站(eNB)。或者，基站12也可以是5G系统中采用集中分布式架构的基站(gNB)。当基站12采用集中分布式架构时，通常包括集中单元(central unit，CU)和至少两个分布单元(distributed unit，DU)。集中单元中设置有分组数据汇聚协议(Packet Data Convergence Protocol，PDCP)层、无线链路层控制协议(Radio Link Control，RLC)层、媒体访问控制(Media Access Control，MAC)层的协议栈；分布单元中设置有物理(Physical，PHY)层协议栈，本公开实施例对基站12的具体实现方式不加以限定。
基站12和终端11之间可以通过无线空口建立无线连接。在不同的实施方式中，该无线空口是基于第四代移动通信网络技术(4G)标准的无线空口；或者，该无线空口是基于第五代移动通信网络技术(5G)标准的无线空口，比如该无线空口是新空口；或者，该无线空口也可以是基于5G的更下一代移动通信网络技术标准的无线空口。

测距信号可以是未携带具体信息内容，只用于进行信号测量的无信息信号。例如，测距信号可以是具有没有特定含义的预定编码的信号，UE可以根据预定编码确定接收到的信号为测距信号。该预定编码没有特定含义。
测距信号还可以是携带具体信息内容的信号。
基站可以主动为驻留的UE配置通信资源，并发送测距资源配置。基站也可以响应于UE的测距请求配置通信资源，并发送测距资源配置。UE可以向基站发送测距请求，并携带需要进行测距测量的UE的标识，基站接收到测距请求后，为测距请求携带的标识所指示的UE配置通信资源，并发送测距资源配置。
这里，基站可以为两个以上的UE分配通信资源，即第一UE可以同时与多个第二UE进行测距信号的交互。从而实现第一UE与多个UE之间的测距测量，进而确定第一UE与多个UE之间的相对位置。
第一UE和第二UE之间的测距测量，可以第一UE和第二UE基于相互传输的测距信号的测量结果，确定第一UE和第二UE相对位置的过程。相对位置可以包括：第一UE与第二UE之间的距离，和/或，第一UE与第二UE之间连线相对预定参考线的夹角等。这里，测量结果可以是UE测量到的测距信号的接收质量参数、测距信号的往返时间、UE针对测距信号的响应时间等。
示例性的，第二UE可以基于预定的发送功率(例如，通过广播)发送测距信号，第一UE可以对第二UE发送的测距信号进行测量，基于测距信号的强度等参数，确定信号的衰减状况，进而推算第一UE和第二UE之间 的距离。第二UE也可以采用相似的方式，推算第一UE和第二UE之间的距离。
如此，第一UE和第二UE不需要建立通信连接，通过基站分配的资源实现测距信号的传输，实现相对位置的确定，进而为UE确定位置提供了多样化的选择。
在一个实施例中，所述方法还包括至少以下之一：
向所述基站发送所述第一UE通过所述测距信号进行测距测量得到的第一测量结果以用于确定所述第一UE与所述第二UE的相对位置；
接收基站发送的所述第二UE提供的所述测距信号进行测距测量得到的第二测量结果；基于所述第二测量结果，确定所述第一UE与第二UE的相对位置。
传输第一测量结果和/或第二测量结果的通信资源可以不同于测距资源配置所配置的通信资源。
在测距测量过程中，第一UE和第二UE通常需要获取对对方的测量结果，进而确定第一UE与所述第二UE的相对位置。
示例性的，第二UE可以采用某一发送功率发送测距信号，第一UE可以对第二UE发送的测距信号进行测量，基于测距信号的强度等参数，确定信号的衰减状况，进而推算第一UE和第二UE之间的距离。第一UE需要获取到发送功率，才能进行距离的推算。
由于测距信号可以是未携带具体信息内容，只用于进行信号测量的无信息信号。对于第一UE和第二UE才测距测量中需要交互的测量结果等数据内容，可以通过基站进行转发。
第一UE可以将自身测量到的测量结果，发送给基站，由基站将测量结果发送给第二UE。第二UE可以将自身测量到的测量结果，发送给基站，由基站将测量结果发送给第一UE。
例如，第二UE可以将自身测距信号的发送功率，发送给基站，由基站将发送功率发送给第一UE。
如此，针对第一UE和第二UE不建立通信连接的情况，实现在测距测量中第一UE和第二UE数据的交换。
在一个实施例中，在一个实施例中，所述方法还包括：
根据所述测距信号在所述第一UE与所述第二UE之间传输的传输总时长，以及所述第一UE对所述测距信号的响应延迟和/或所述第二UE对所述测距信号的响应延迟，确定所述第一UE和所述第二UE之间的距离。
这里，在测距信号交互过程中，测距信号可以是一种触发信号。第一UE可以向第二UE发送测距信号，第二UE受到测距信号的触发，向第一UE发送测距信号。第一UE接收的测距信号后，同样可以受到触发向第二UE返回测距信号。第一UE和第二UE响应测距信号并触发返回测距信号的次数可以预先约定或由通信协议规定。一次测距过程中，测距信号由第一UE或第二UE发送至少一次，测距信号第一次被UE1或UE2发送的时刻，到测距信号最后一次被UE1或UE2接收的时刻之间的时长，可以称为传输总时长。传输总时长可以包括一个或多个RTT。
示例性的，可以约定第一UE不被测距信号触发，第二UE可以被触发一次，则第一UE发送测距信号后，第二UE响应该测距信号向第一UE发送测距信号，第一UE接收到第二UE发送的测距信号后，不再返回测距信号。这种情况下第一UE和第二UE各发送一次测距信号，完成测距信号的单次往返。
相似的，也可以由第二UE首先发送测距信号，完成测距信号的单次往返。
RTT可以是第一UE从发送一个测距信号的时刻，到接收到第二UE基于第一UE发送的测距信号的响应的时刻之间的时长，其中第二UE发送的 响应可以为测距信号。或者，RTT也可以是第二UE从发送一个测距信号的时刻，到接收到第一UE基于第二UE发送的测距信号的响应的时刻之间的时长，其中第一UE发送的响应可以为测距信号。
第一UE对所述测距信号的响应延迟，可以是第一UE接收到测距信号，并对测距信号做出响应，向第二UE发送测距信号所需的时间。
第二UE对所述测距信号的响应延迟，可以是第二UE接收到测距信号，并对测距信号做出响应，再向第一UE发送测距信号所需的时间。
将测距信号的传输总时长减去，在测距信号往返过程中实际产生的第一UE对所述测距信号的响应延迟和/或第二UE对所述测距信号的响应延迟，可以得到测距信号时间在空间中传输的时长。最后根据测距信号在第一UE和第二UE之间传输的次数，得到单次测距信号在第一UE和第二UE之间传输的时长。进而根据测距信号在空间中的传播速度确定第一UE和第二UE之间的距离。
如此，实现第一UE和第二UE之间的距离的确定。
在一个实施例中，所述根据所述测距资源配置，与第二UE进行测距信号的通信以进行所述第一UE和第二UE之间的测距测量，包括：
在所述测距资源配置所配置的发送资源上发送测距信号；
在所述测距资源配置所配置的接收资源上接收所述第二UE基于所述第一UE的测距信号返回的测距信号。
可以由基站配置资源池。发送测距信号时，UE可以根据需求在配置的资源池中选择的资源上发送测距信号，或者UE可以在基站指定的具体资源上发送测距信号。监听测距信号时，UE可以在配置的资源池中监听测距信号，或者UE可以在基站指定的具体资源上监听测距信号。针对由第一UE发起的测距信号的情况，第一UE可以在测距资源配置所配置的发送资源上发送测距信号，并启动定时器进行计时。
第二UE可以在该发送资源上进行监听。当第二UE监听到测距信号后，可以返回测距信号。第二UE可以通过定时等方式记录自身响应接收到的测距信号至向第一UE发送测距信号的响应延迟。

当第一UE监听到测距信号后，可以在测距资源配置所配置的发送资源上返回测距信号。第一UE可以通过定时等方式记录自身响应接收到的测距信号至向第二UE发送测距信号的响应延迟。
第二UE可以监听第一UE响应于第二UE的测距信号所返回的测距信号，并根据第二UE发送测距信号的时刻以及接收到返回的测距信号的时刻确定第二RTT。
在一个实施例中，所述传输总时长包括：所述第二UE发送测距信号的发送时刻，与所述第二UE接收到所述第一UE基于所述第二UE的测距信号返回的测距信号的接收时刻之间的第二RTT。

相似的，如图4所示，针对由第二UE发起的测距信号的单次往返的情况，传输总时长即为第二RTT。
如图5所述，由第一UE发送的测距信号1，第二UE接收到测距信号1后向第一UE发送测距信号2，第一UE接收到测距信号2后，向第二UE发送测距信号3。在该测距信号多次往返的情况下，传输总时长为第一RTT和第二RTT之和。
相似的，针对由第二UE发起的测距信号多次往返的情况，传输总时长即为第二RTT与第一RTT之和。
以此类推，测距信号多次往返的情况中，传输总时长包含不同数量的RTT，以及多个响应延迟。可以根据不同数量的RTT以及多个响应延迟确定第一UE和第二UE之间的距离。
在一个实施例中，所述方法还包括：

针对图4所示的由第二UE发起的测距信号的单次往返的情况，RTT即为第二RTT。第二RTT可以由第二UE确定，第一UE对测距信号的响应延迟由第一UE确定，因此，第二UE可以将确定的第二RTT，通过基站转发给第一UE，进而，可以实现第一UE对第一UE和第二UE之间的距离的确定。
针对图3所示的由第一UE发起的测距信号的单次往返的情况，RTT即为第一RTT。。第一RTT可以由第一UE确定，第二UE对测距信号的响应延迟由第二UE确定。因此，第二UE可以将第二UE对测距信号的响应延迟，通过基站转发给第一UE，进而，可以实现第一UE对第一UE和第二UE之间的距离的确定。
针对图5所示的由第二UE发起的测距信号的多次往返的情况，第一UE需要在确定第一RTT、第二RTT、第一UE对所述测距信号的响应延迟以及第二UE对所述测距信号的响应延迟的情况下，才能计算第一UE对第一UE和第二UE之间的距离。第二UE可以将由自身确定的第二RTT以及第二UE对测距信号的响应延迟，通过基站转发给第一UE，实现第一UE对第一UE和第二UE之间的距离的确定。
在一个实施例中，所述方法还包括：
