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
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)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。
现有NR系统中，下行授予(Downlink Grant)DCI(Downlink Control Information，下行控制信息)包括DAI(Downlink Assignment Index，下行分配索引)域，用以支持基于码本(Codebook)的HARQ-ACK(应答)。
发明内容
发明人通过研究发现：对于LAA通信尤其是SA(Stand Alone，孤立的)-LAA通信，UE(User Equipment，用户设备)在上行HARQ-ACK发送之前需要执行LBT，因此上行HARQ-ACK的发送时刻很可能是不确定的。在LAA通信中如何传输上行HARQ-ACK是一个需要解决的问题。
针对上述发现，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。进一步的，虽然本发明的初衷是针对LAA通信，本申请中的方法和装置也适用于在授权频谱上的通信。
本申请公开了被用于无线通信的用户设备中的方法，其特征在于，包括：
-在Q个时间窗中分别接收Q个控制信令组，所述Q个控制信令组中任一控制信令组包括正整数个控制信令；
-接收第一控制信令，所述第一控制信令被用于确定所述Q个时间窗中Q1个时间窗；
