Description

一种被用于无线通信的用户设备、基站中的方法和装置 技术领域
本申请涉及无线通信系统中的方法和装置，尤其是涉及支持在非授权频谱(Unlicensed Spectrum)上进行数据传输的无线通信系统中的方法和装置。
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)#75次全会上通过了NR(New Radio，新无线电)下的非授权频谱(Unlicensed Spectrum)的接入的研究项目。在LTE(Long Term Evolution，长期演进)的LAA(License Assisted Access，授权辅助接入)项目中，发射机(基站或者用户设备)在非授权频谱上发送数据之前需要先进行LBT(Listen Before Talk，会话前监听)以保证不对其他在非授权频谱上正在进行的无线传输造成干扰。
在LTE系统中，基于码本的预编码是实现多天线传输的一项重要手段。在基于码本的预编码技术中，接收端需要通过测量参考信号来估计信道状态信息，并把估计出的信道状态信息反馈/通知给发送端。在NR系统中，由于天线数量的急剧增加，这种基于码本的预编码所需的信道估计和反馈/通知开销也会随之增大。为了降低开销并提高预编码精度，基于非码本的上行传输在3GPP RAN1中被提出。根据3GPP RAN1的讨论结果，基于码本的和基于非码本的上行传输在NR系统中同时被支持。一个UE是工作在基于码本的上行传输模式下还是工作在基于非码本的上行传输模式下是由高层信令配置的。
发明内容
在基于非码本的上行传输中，UE(User Equipment，用户设备)根据对下行参考信号的测量来决定上行参考信号的预编码矩阵并发送相应的上行参考信号，相同的预编码矩阵将被用于随后的上行数据传输。基站通过测量上行参考信号来决定上行数据传输的调度信息，比如发送天线端口和MCS(Modulation and Coding Scheme，调制编码方式)。发明人通过研究发现，在非授权频谱下由于LBT的影响，下行参考信号的发送将无法被保证。如果收不到相应的下行参考信号，UE将无法工作在基于非码本的上行传输模式下。
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。
