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。PSFCH(Physical Sidelink Feedback Channel，物理副链路反馈信道)信道被引入用于副链路上的HARQ-ACK(Acknowledgement,确认)传输。根据3GPP RAN1#96b会议的结果，一个副链路资源池中的PSFCH资源将被周期性的配置或预配置。根据3GPP RAN1#97会议的结果，PSSCH(Physical Sidelink Shared Channel，物理副链路共享信道)所占用的时隙和子信道(sub-channel)会被用于确定对应的PSFCH资源。
发明人通过研究发现，当针对同一个节点的多个PSFCH在时域发生冲突时，PSFCH的发送节点可以将不同PSFCH上的内容复用到同一个PSFCH上，从而避免HARQ-ACK信息的缺失和导致的资源浪费。复用的设计是一个需要解决的问题。
针对上述问题，本申请公开了一种解决方案。需要说明的是，虽然上述描述采用副链路通信场景作为一个例子，本申请也适用于其他蜂窝网通信场景，并取得类似在副链路通信场景中的技术效果。此外，不同场景(包括但不限于副链路通信和蜂窝网通信)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。
