Description

一种用于无线通信的方法和装置 技术领域
本发明涉及无线通信系统中的方法和装置，尤其涉及无线通信系统中的用于定位的方案和装置。
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，回程时间)技术、SL AOA(Angle of Arrival，到达角)、SL TDOA(Time Difference Of Arrival,到达时间差)和SL AOD(Angle of Departure，离开角)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。由于未来SL PRS的发送者可以支持多个波束方向上的传输，这就使得传统的用于定位的流程或者位置信息反馈方案需要进一步增强，进而副链路上位置信息(Location Information)的测量及获取，也需要被重新考虑，并加以增强。
针对上述问题，本申请公开了一种解决方案。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。特别的，对本申请中的术语(Terminology)、名词、函数、变量的解释(如果未加特别说明)可以参考3GPP的规范协议TS36系列、TS38系列、TS37系列中的定义。在需要的情况下，可以参考3GPP标准TS38.211，TS38.212，TS38.213，TS38.214，TS38.215，TS38.321，TS38.331，TS38.305，TS37.355以辅助对本申请的理解。
本申请公开了一种用于无线通信的第一节点中的方法，包括：
接收第一信息块集合和第一参考信号，所述第一信息块集合被用于指示第一身份，所述第一身份被用于标识所述第一参考信号；
发送第一位置信息；
其中，所述第一参考信号通过副链路传输，针对所述第一参考信号的接收被用于确定所述第一位置信息；所述第一身份被用于确定以下至少之一：
-所述第一参考信号的同步参考；

根据本申请的一个方面，其特征在于，包括：
接收第二参考信号；
其中，所述第二参考信号通过副链路传输，第二身份被用于标识所述第二参考信号；所述第二身份是否与所述第一身份相同被用于确定针对所述第二参考信号的接收能否被用于确定所述第一位置信息。
作为一个实施例，上述方法的特征在于：和所述第一参考信号具有相同身份的参考信号能够与所述第一参考信号联合接收以获得位置信息，进而改进定位性能。
根据本申请的一个方面，其特征在于，当所述第二身份和所述第一身份相同时，所述第一参考信号和所述第二参考信号之间的关系满足以下至少之一：
