第一UE确定第二测量结果后，可以仅基于第二测量结果确定第一UE和第二UE之间的位置信息(例如相对位置)。也可以基于第一测量结果和第二测量结果确定第一UE和第二UE之间的位置信息(例如相对位置)。
示例性的，第一UE可以将第一UE测量得到的信号发送接收时间差，减去第二UE测量得到的信号接收发送时间差，从而得到信号在第一UE和第二UE之间的飞行时间、再结合到达角和离开角。。这里，第一UE测量得到的信号发送接收时间差可以是第一UE发送第一定位参考信号的时刻与第一UE接收到第二定位参考信号之间的时间差。第二UE测量得到的信号接收发送时间差可以是第二UE接收第一定位参考信号的时刻与第二UE发送第二定位参考信号的时刻之间的时间差。如此，可以得到更为精确的第一UE和第二UE之间的相对位置。

示例性的，第二UE接收到第一定位参考信号后，可以发送第二定位参考信号给第一UE，第一UE可以将发送第一定位参考信号和接收到第二定位参考信号的时间差发送给第二UE。第二UE可以确定第一定位参考信号到达第二UE的时刻和发送第二定位参考信号的时刻之间的时间差，即Rx–Tx time difference。第二UE基于第一定位参考信号的发送时刻和第二定位参考信号的接收时刻之间的时间差，以及Rx–Tx time difference可以确 定参考信号的飞行时间，进而确定第一UE和第二UE的星对距离。
在一个实施例中，所述通过第二类无线网络与第二UE传输关联于所述定位参考信号的交互信息，包括：
响应于接收到指示所述第一参考信号配置的指示信息，通过所述第二类无线网络，向所述第一UE发送所述第二参考信号配置。
第二UE在接收到指示所述第一参考信号配置的指示信息后，可以认为第一UE需要进行定位，因此，可以将第二参考信号配置发送给第一UE，用于传输第二定位参考信号。
以下结合上述任意实施例提供一个具体示例：
1、UE1向UE2发送信息，该信息包含了UE1的参考信号配置，所述参考信号配置用于UE之间的相对定位/测距/感知，且该参考信号为UE在上行Uu口发送。
2、该参考信号可以为SRS/positioning SRS,或者新定义的在Uu口发送的上行参考信号；

5、UE2收到UE1发送的所述信息，UE2向UE1发送指示信息，所述指示信息包含UE2的参考信号配置；
6、UE2收到UE1的相对定位/测距/感知请求后，根据步骤1中所述UE1的参考信号配置完成参考信号的测量，测量包括Rx–Tx time difference，和/或到达角，和/或离开角；并将所述测量结果发送给UE1(通过PC5接口)；
7、UE1根据收到的参考信号配置对参考信号进行测量，测量包括Rx–Tx time difference，和/或到达角，和/或离开角；并将所述测量结果发送给UE2(通过PC5接口)；
8、UE1根据步骤7中所述测量结果和步骤6中收到所述UE2的测量结果，完成相对定位；
9、UE2根据6中所述测量结果以及7中UE1的测量结果，完成相对定位。
