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)。
但由于时间限制，NR SL Rel-16不能完全支持足3GPP为5G V2X识别的业务需求和工作场景。因此3GPP将在Rel-17中研究增强NR SL。
发明内容
一般VRU(Vulnerable road user，弱势道路用户)和PUE(Pedestrian user equipment，行人用户设备)的电池寿命较短，处理复杂度较低。为了节省功率，VRU或者PUE经常采用随机资源选择，周期性部分感知或者连续部分感知的方式确定发送信号的时频资源。在NR SL系统中，允许随机资源选择，部分感知以及完全感知的用户共享同一个资源池，当一个感知用户感知到临近的VRU或者PUE用户所占用的时频资源，尽管感知用户的数据优先级高于临近的VRU或者PUE的数据优先级，但由于VRU或者PUE采用随机资源选择的方式而不执行信道感知导致无法避免对临近用户的干扰，感知用户不得不采取主动避让干扰的时频资源，导致高端的感知用户的传输性能受到影响。因此，对共享资源池会设一个阈值，当VRU或者PUE的数据优先级较低时避免进入该共享资源池，以免引发对高端感知用户的性能影响。但是当该资源池用户数较少，资源比较丰富时，采用统一优先级阈值将会导致资源利用率较低。
针对上述问题，本申请公开了一种用于资源池的优先级阈值设定方法，从而有效避免资源池利用率不高的问题。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。
