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 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
NRV2X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可以支持单播功能并支持CSI(Channel-State Information，信道状态信息参考信号)获取。CSI的获取需要参考信号的支持。在V2X中，当参考信号的发送节点因为某些原因改变参考信号的发送功率时，参考信号的接收节点对CSI的计算会受到影响，甚至导致参考信号的发送节点和接收节点对获取的CSI的理解产生歧义。
