Description

一种被用于无线通信的节点中的方法和装置 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副链路(Sidelink)相关的传输方案和装置。
背景技术
从LTE(Long Term Evolution，长期演进)开始，3GPP(3rd Generation Partner Project，第三代合作伙伴项目)已经在发展SL(Sidelink，副链路)作为用户与用户之间的直连通信方式，并在Rel-16(Release-16，版本16)中完成了“5G V2X with NR Sidelink”的第一个NR SL(New Radio Sidelink，新空口副链路)标准。在Rel-16中，NR SL主要被设计用于V2X(Vehicle-To-Everything，车联网)，但它也可以用于公共安全(Public Safety)。随着NR SL进一步增强，Rel-17引入了周期性的部分感知(periodic-based partial sensing，PBPS)，连续性的部分感知(contiguous partial sensing，CPS)，随机选择(random selection)和非连续接收(Discontinuous Reception，DRX)等功率节省方案，也引入了多种用户间协调(inter-UE coordination)方案以提供更可靠的信道资源。
为了满足商业化的应用场景，工业界又对V2X提出了新的需求，更高的数据吞吐量以及对新载波频率的支持。因此，在3GPP RAN-#94e次会议上，通过了针对NR SL演进的工作项目说明(Work Item Description，WID)RP-213678，正式开启了NR V2X Rel-18的标准化工作。
发明内容
根据RP-213588中的工作计划，NRRel-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、SLAOA、SLTDOA和SLAOD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。不同于DL PRS(Downlink Positioning Reference Signal，下行定位参考信号)，一个SLBWP(Bandwidth Part，带宽部件)上需要分配用于承载SL PRS的资源池。而现有的SL资源池的确定方法无法满足SL PRS的需求，严重影响SL的资源利用率。
针对上述问题，本申请公开了一种针对SL PRS的资源池确定方法，从而有效提高SL资源的利用率。需要说明的是，在不冲突的情况下，本申请的用户设备中的实施例和实施例中的特征可以应用到基站中，反之亦然。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。进一步的，虽然本申请的初衷是针对SL，但本申请也能被用于UL(Uplink，上行链路)。进一步的，虽然本申请的初衷是针对单载波通信，但本申请也能被用于多载波通信。进一步的，虽然本申请的初衷是针对单天线通信，但本申请也能被用于多天线通信。进一步的，虽然本申请的初衷是针对V2X场景，但本申请也同样适用于终端与基站，终端与中继，以及中继与基站之间的通信场景，取得类似的V2X场景中的技术效果。此外，不同场景(包括但不限于V2X场景和终端与基站的通信场景)采用统一的解决方案还有助于降低硬件复杂度和成本。
需要说明的是，对本申请中的术语(Terminology)的解释是参考3GPP的规范协议TS36系列，TS37系列和TS38系列中的定义，但也能参考IEEE(Institute of Electrical and Electronics Engineers,电气和电子工程师协会)的规范协议的定义。
