Description
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。
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。在Cat 4 LBT(第四类型的LBT,参见3GPP TR36.889)过程中,发射机在一定的延时时段(Defer Duration)之后还要进行回退(backoff),回退的时间以CCA(Clear Channel Assessment,空闲信道评估)时隙时段为单位进行计数,回退的时隙时段数量是发射机在CWS(Contention Window Size,冲突窗口大小)内进行随机选择得到的。对于下行传输,CWS是根据在该非授权频谱上的之前传输的一个参考子帧(reference sub-frame)中的数据所对应的HARQ(Hybrid Automatic Repeat reQuest,混合自动重传请求)反馈进行调整的。对于上行传输,CWS是根据在该非授权频谱上之前的一个参考子帧中的数据中是否包括新数据来进行调整的。
大规模(Massive)MIMO(Multi-Input Multi-Output)是NR系统的另一个研究热点。大规模MIMO中,多个天线通过波束赋型,形成较窄的波束指向一个特定方向来提高通信质量。在NR系统中,大规模MIMO会被应用于毫米波频段的非授权频谱。
发明内容
发明人通过研究发现,在NR系统中,由于采用了大规模MIMO技术,在不同波束方向上的干扰状况会存在很大差异,因此在确定CWS的时候需要考虑到波束方向的影响。如果发送节点在做LBT时使用了某个特定的波束,CWS需要能够正确反应这个特定波束方向上的干扰状况,这对于参考子帧的选择提出了新的要求。
