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和副链路(Sidelink)相关的传输方法和装置。
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已经完成面向5G V2X业务的需求制定工作，并写入标准TS22.886。3GPP为5G V2X业务定义了4大应用场景组(Use Case Groups)，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。
发明内容
NR V2X和现有的LTE(Long-term Evolution，长期演进)V2X系统相比，一个显著的特征在于支持单播和组播并支持HARQ(Hybrid Automatic Repeat reQuest，混合自动重传请求)功能。为支持副链路上HARQ-ACK(Acknowledgement,确认)的传输，PSFCH(Physical Sidelink Feedback Channel，物理副链路反馈信道)信道被引入。根据3GPP RAN1 #96b会议的结果，PSFCH资源可以被周期性的配置或预配置。
在3GPP RAN1#97次全会上，对于组播(Groupcast)的HARQ-ACK，V2X中的接收UE(User Equipment，用户设备)通过确定与V2X中的发送UE之间的距离判断是否需要发送HARQ反馈，从而有效避免在副链路上不必要的反馈信道的开销。未来V2X应用场景中，终端将会配置多个面板(Panel)，且多个面板可以采用不同的波束赋形向量进行发送或接收以提高系统性能。当多个面板之间的距离较远，或者多个面板对应不同的波束赋形向量时，上述基于位置信息确定副链路上HARQ发送方式的方案在多TRP的场景下需要被重新设计。
针对上述问题，本申请公开了一种解决方案。需要说明的是，在不冲突的情况下，本申请的第一节点中的实施例和实施例中的特征可以应用到第二节点中，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。
