Description

一种被用于定位的方法和装置 技术领域
本申请涉及无线通信系统中的传输方法和装置，尤其涉及无线通信中的与定位相关的方案和装置。
背景技术
定位是无线通信领域的一个重要应用；V2X(Vehicle to everything，车对外界)或者工业物联网等新应用的出现，对定位的精度或者延迟提出了更高的要求。在3GPP(3rd Generation Partner Project，第三代合作伙伴项目)RAN(Radio Access Network，无线接入网)#94e会议中，关于定位增强的研究课题被立项。
发明内容
根据RP-213588中的工作计划，NR Rel-18需要支持副链路定位(Sidelink Positioning，SL Positioning)的增强定位技术，其中主流的副链路定位技术包括基于SL RTT(Round Trip Time，往返时间)技术、SL AOA(Angle-of-Arrival，到达角)、SL TDOA(Time Difference of Arrival，到达时差)和SL AOD(Angle-of-Departure，偏离角)等，而这些技术的执行都需要依赖对SL PRS(Sidelink Positioning Reference Signal，副链路定位参考信号)的测量。对于副链路定位技术，尤其是基于SL RTT技术，需要做进一步的增强，进而提高SL定位准确度。
针对上述问题，本申请公开了一种定位解决方案。需要说明的是，在本申请的描述中，只是采用V2X场景作为一个典型应用场景或者例子；本申请也同样适用于面临相似问题的V2X之外的场景，例如公共安全(Public Safety)、工业物联网等等，并取得类似NR V2X场景中的技术效果。此外，虽然本申请的动机是针对用于定位测量的无线信号的发送者是移动的这一场景，本申请依然适用于用于定位测量的无线信号的发送者是固定的这一场景，例如RSU(Road Side Unit，路边单元)等。不同场景采用统一解决方案还有助于降低硬件复杂度和成本。在不冲突的情况下，本申请的任一节点中的实施例和实施例中的特征可以应用到任一其他节点中。在不冲突的情况下，本申请的实施例和实施例中的特征可以任意相互组合。
