Description

一种基站、用户设备中的用于无线通信的方法和装置 技术领域
本申请涉及无线通信系统中的无线信号的传输方案，特别是涉及多天线传输与非授权频谱的方法和装置。
背景技术
传统的3GPP(3rd GenerationPartner Project，第三代合作伙伴项目)LTE(Long-term Evolution，长期演进)系统中，数据传输只能发生在授权频谱上，然而随着业务量的急剧增大，尤其在一些城市地区，授权频谱可能难以满足业务量的需求。Release 13及Release 14中非授权频谱上的通信被蜂窝系统引入，并用于下行和上行数据的传输。为保证和其它非授权频谱上的接入技术兼容，LBT(Listen Before Talk，会话前侦听)技术被LAA(Licensed Assisted Access，授权频谱辅助接入)采纳以避免因多个发射机同时占用相同的频率资源而带来的干扰。LTE系统的发射机采纳准全向天线来执行LBT。
目前，5G NR(New Radio Access Technology，新无线接入技术)的技术讨论正在进行中，其中大规模(Massive)MIMO(Multi-Input Multi-Output)成为下一代移动通信的一个研究热点。大规模MIMO中，多个天线通过波束赋型(Beamforming)，形成指向一个特定空间方向的波束来提高通信质量，当考虑到波束赋型带来的覆盖特性时，传统的LAA技术需要被重新考虑，比如LBT方案。
发明内容
发明人通过研究发现，5G系统中，波束赋型将会被大规模使用，如何通过波束赋型在非授权频谱上提升无线信号的传输效率是一个需要解决的关键问题。
