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***中的传输方法和装置，尤其涉及无线通信中多天线相关的传输方案和装置。
背景技术
未来无线通信***的应用场景越来越多元化，不同的应用场景对***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)。
发明内容
为了满足新的业务需求，相比LTE V2X***，NR V2X***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。进一步的，NR V2X将被应用于更高频段。目前，3GPP正在讨论6GHz以上的副链路(Sidelink)信道模型。
同步是副链路传输的先决条件。为了让用户设备(User Equipement,UE)间保持同步，***会指导用户设备在副链路上发送同步信号(Sidelink Synchronization Signal，SLSS)和一些必要的***信息。用户设备通过这些同步信号获取副链路发送或接收的时间和频率同步。当一个用户设备收到来自多个用户设备的SLSS时，这个用户设备需要区分这些用户设备的优先级，从而选择一个SLSS作为它的同步参考。
由于现有的LTE D2D/V2X主要应用于低频段，SLSS主要采用单波准全向的传输方案。然而高频场景具有信号衰减严重，传输距离短，极宽带宽，波束窄等传播特性，预计NR***的SLSS将会采用多波束传输。因此一个用户设备可能会收到来自多个用户设备不同波束的SLSS，这个用户设备如何从多波束的SLSS中选择一个SLSS作为它的同步参考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，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多天线的传输，但本申请也能被用于单天线传输。更进一步的，虽然本申请的初衷是针对高频段通信，但本申请也能被用于低频段通信。
