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
未来无线通信系统的应用场景越来越多元化，不同的应用场景对系统提出了不同的性能要求。为了满足多种应用场景的不同的性能需求，在3GPP(3rd Generation Partner Project，第三代合作伙伴项目)RAN(Radio Access Network，无线接入网)#72次全会上决定对新空口技术(NR，New Radio)(或Fifth Generation，5G)进行研究,在3GPP RAN#75次全会上通过了NR的WI(Work Item，工作项目)，开始对NR进行标准化工作。
针对迅猛发展的车联网(Vehicle-to-Everything，V2X)业务，3GPP也开始启动了在NR框架下的标准制定和研究工作。目前3GPP已经完成了面向5G V2X业务的需求制定工作，并写入标准TS22.886中。3GPP为5G V2X业务识别和定义了4大用例组(Use Case Group)，包括：自动排队驾驶(Vehicles Platnooning)，支持扩展传感(Extended Sensors)，半/全自动驾驶(Advanced Driving)和远程驾驶(Remote Driving)。在3GPP RAN#80次全会上已启动基于NR的V2X技术研究，且在RAN1 2019第一次AdHoc会议上同意将V2X对中发送端和接收端的Pathloss(路径损耗)作为V2X的发射功率的参考。
发明内容
NR V2X和现有的LTE V2X系统相比，一个显著的特征在于可以支持组播和单播以及支持HARQ(Hybrid Automatic Repeat Request，混合自动重传请求)功能。在传统的蜂窝系统中，基站对接入网络的用户设备具有完全控制能力，基站下发的指令，用户设备完全执行。然而在V2X系统中，车与车之间的关系对等，没有隶属关系，用户设备A发送的指令或请求，用户设备B不一定执行。例如，用户设备A指定的资源对于用户设备B不可用，或者，用户设备B的工作状态对于用户设备A不透明等。在所述用户设备A不知情的情况下，用户设备A可能会对用户设备B再次发送指令，从而导致信令开销和资源的浪费，同时用户设备A的请求被耽误处理。随着分布式系统的应用越来越广泛，这种用户设备未执行接收到的指令的情况越来越多。
针对上述问题，本申请公开了一种副链路反馈的解决方案，有效地解决了分布式系统中对等节点之间的通信问题。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。
