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***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***中的方法和装置。
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)#75次全会上还通过NR(New Radio，新无线电)下的非授权频谱(Unlicensed Spectrum)的接入的研究项目，该研究项目预期在R15版本完成，然后在R16版本中启动WI对相关技术进行标准化。
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。
发明内容
发明人通过研究发现，在NR-U(NR-Unlicensed spectrum，NR非授权频谱)***中，尤其是部署于SA(Stand Alone孤立的)场景下的NR-U***中，由于MCOT(Max Channel Occupy Time,最大信道占用时间)和LBT等限制因素，基于调度的上行数据和上行控制信息的发送时间并不总能被基站准确预测。这给上行传输的调度带来了新的问题。考虑到NR***中将广泛采用基于大规模天线阵列的波束赋型，不同波束赋型方向上的信道占用和干扰状况会存在很大差异，因此在进行LBT时需要考虑到波束方向的影响，这使得上行数据和上行控制信息的发送时间更加难以预测。
