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技术、SL AOA、SL TDOA和SL AOD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UE(User Equipment，用户设备)自主选择资源用于发送SL PRS，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。
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。
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。
本申请公开了一种被用于无线通信的第一节点中的方法，其特征在于，包括：
在第一时间窗内的M个第一类资源上分别测量得到M个第一类RSSIs(Received Signal Strength Indicators，接收信号强度指示)，M是大于1的正整数；
确定在第一目标时域资源块上是否发送第一定位参考信号；
其中，第一资源池包括所述M个第一类资源，所述M个第一类资源采用第一配置；所述第一目标时域资源块被用于确定所述第一时间窗；第一信道繁忙比是在所述第一时间窗内被测量得到的第一类RSSI超过第一阈值的第一类资源的比例；所述第一信道繁忙比被用于确定在所述第一目标时域资源块上是否发送所述第一定位参考信号。
作为一个实施例，本申请要解决的问题是：在UE自主选择SL PRS资源的模式下，当被用于发送SLPRS的资源池过于拥塞时，UE自主选择资源后直接发送SL PRS，对其他UEs造成严重的干扰。
作为一个实施例，本申请要解决的问题是：在UE自主选择SL PRS资源的模式下，在过于拥塞的资源池内发送SL PRS，导致SL PRS接收效果不好，从而产生严重的测量误差。
作为一个实施例，本申请的方法是：将SL PRS占用的资源与RSSI测量建立关系。
作为一个实施例，本申请的方法是：将信道繁忙比与SL PRS是否发送建立关系。
