步骤1)、网络节点LMF(可以对应上文中的第三设备)可以触发感测测量,可选的,向gNB(可以对应上文中的第二设备)发送感知测量请求消息(可以对应上文中的第二消息)。

步骤4)、UE将测量结果报告给LMF。
步骤5)、LMF可以基于UE上报的测量结果,计算目标的位置。
下面结合如图6b所示的内容,详细描述上述步骤3)的实现过程:
·步骤1:通过测量TRP1和UE之间感应参考信号的直接路径(例如:LOS路径/第一路径)的到达时间,获得“ToA_direct1”;
·步骤2-1:通过测量TRP1和UE之间感应参考信号的另一路径(例如:第二个到达)的到达时间,获得“ToA_reflect1-0”,该路径由目标0反射;
·步骤2-2:通过测量由目标1反射的TRP1和UE之间的感测参考信号的另一路径(例如:第三个到达)的到达时间,获得“ToA_reflect1-1”;
·注意:在检测到的两个相邻路径之间存在阈值(可以参见附图6c)。
·步骤2-3:UE向LMF报告ToA_set1={ToA_direct1,ToA_reflect1-0,ToA_reflect1-1,…ToA_refract1-K1};
·步骤3:与步骤2相同,UE向LMF报告ToA_set2={ToA_direct2,ToA_reflect2-0,ToA_reflect2-1,…ToA_refract2-K1};以及
·ToA_set3={ToA_direct3,ToA_reflect3-0,ToA_reflect3-1,…ToA_refract3-K1};
·步骤4:在LMF侧(例如:LPP服务器),可以计算出“椭圆1,椭圆2,椭圆3”的坐标,然后检查椭圆1,椭圆2,椭圆3之间的重叠点。
·理想情况下,如果只有一个点与所有三个椭圆重叠,则可以知道该目标(例如:目标0)的坐标。
