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传输方法和装置，尤其是涉及支持在非授权频谱(Unlicensed Spectrum)上进行数据传输的通信方法和装置。
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形(Beamforming)，形成指向一个特定空间方向的波束来提高通信质量，当考虑到波束赋形带来的覆盖特性时，传统的LAA技术需要被重新考虑，比如基于LBT的无线信号传输。
发明内容
发明人通过研究发现，在NR系统中，波束赋形将会被大规模使用，在保证避免多个发射机之间的同频干扰的情况下，如何提高信道接入机会，提升系统容量是需要解决的一个关键问题。
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，本申请的实施例和实施例中的特征可以任意相互组合。
本申请公开了一种用于无线通信的用户设备中的方法，其特征在于，包括：
接收第一无线信号，所述第一无线信号被第一天线端口组发送；
接收第一信息；
执行第一接入检测以确定是否在第一子频带上的第一时刻进行上行发送；如果是，在所述第一子频带上的第一时刻通过第二天线端口组发送第二无线信号；如果否，放弃在所述第一子频带上的第一时刻发送第二无线信号；
其中，所述第一天线端口组包括正整数个天线端口，所述第二天线端口组包括正整数个天线端口；第一接收参数组被用于所述第一无线信号的接收，第二接收参数组被用于生成所述第二天线端口组；所述第一接收参数组和所述第二接收参数组都属于第一接收参数空间，所述第一信息和所述第一接收参数组共同被用于确定所述第一接收参数空间。
作为一个实施例，本申请要解决的问题是：在NR系统中，由于采用了大规模MIMO技术来发送无线信号，在不同波束方向上的干扰状况会存在很大差异，基于波束的LBT可以更真实的反应一个特定波束方向上的干扰情况。在非授权(Grant free)上行传输中，用户设备的上行业务量通常比较小，且下行接收受限，用户设备通常在基站预留的时频资源采用预分配的波束进行非授权上行传输。通常预分配的波束的更新比较慢，那么就不能随着信道变化或干扰环境的变化对该波束进行快速调整，这样可能会对信道接入机会或上行传输产生影响。因此，如何提高信道接入机会，提升系统容量是一个需要解决的关键问题。
作为一个实施例，上述方法的实质在于，第一接收参数空间对应一个有限的波束范围，该波束范围包括多个波束。用户设备可以在这个波束范围内监听信道，如果基于其中一个波束的LBT检测结果为信道空闲，那么用户设备可以采用这个波束进行上行无线信号传输。采用上述方法的好处在于，与采用一个预配置的波束相比，提高了上行信道接入机会，从而提升了系统容量。
