Description

一种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的组播、多播或广播的传输方案和装置。
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5G)进行研究,在3GPP RAN#75次全会上通过了新空口技术(NR，New Radio)的WI(Work Item，工作项目)，开始对NR进行标准化工作。在3GPP RAN#86次全会上决定开始NR Rel-17的SI(Study Item，研究项目)和WI(Work Item，工作项目)的工作。
采用新空口技术的众多应用场景中需要支持多播(Multicast)与广播(Broadcast)业务传输，比如固件升级、视频广播等。在NR Rel-17中，为了支持多播与广播业务，在3GPP RAN#86次全会上通过了NR下的多播与广播业务的WI，开始相关的标准化工作。
发明内容
多播与广播传输的WI中支持针对多播/广播传输的HARQ反馈来提高多播/广播传输的鲁棒性。针对多播/广播传输的HARQ反馈问题，本申请公开了一种解决方案。需要说明的是，在本申请的的描述中，只是将多播/广播传输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其它场景(比如存在多种业务共存的场景，或者一个服务小区内对同一个用户设备存在多个并行的下行传输的场景等)，也可以取得类似的技术效果。此外，不同场景(包括但不限于多播/广播传输的场景)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，本申请的第一节点设备中的实施例和实施例中的特征可以应用到第二节点设备中，反之亦然。特别的，对本申请中的术语(Terminology)、名词、函数、变量的解释(如果未加特别说明)可以参考3GPP的规范协议TS36系列、TS38系列、TS37系列中的定义。
