Description

一种被用于无线通信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)上进行的通信方法和装置。
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业务定义了4大应用场景组(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。
发明内容
为了满足新的业务需求，相比LTE V2X系统，NR V2X系统具有更高吞吐量，更高可靠性，更低延时，更远传输距离，更精准定位，数据包大小和发送周期可变性更强，以及与现有3GPP技术和非3GPP技术更有效共存的关键技术特征。当前LTE V2X系统的工作模式仅限于广播(Broadcast)传输。根据在3GPP RAN#80次全会上达成的共识，NR V2X将研究支持单播(Unicast)，组播(Groupcast)和广播多种工作模式的技术方案。
在当前LTE D2D(Device to Device，设备到设备)/V2X的工作模式下，用户设备通过Sidelink发送的无线信号是广播的，不会针对某一特定用户设备发送无线信号。当存在针对某一特定用户设备的大数据包业务时，通过广播传输的工作模式，资源利用效率非常低，也无法保证可靠传输；因此需要NR背景下的D2D及V2X考虑单播传输以提高频谱效率和传输性能。
针对上述问题，本申请公开了一种解决方案用以支持单播传输。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基于单播的传输机制，但本申请也能被用于广播和组播传输。更进一步的，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。
