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LBT(Listen Before Talk，监听后发送)上进行通信方法和装置。
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，由于系统带宽可能会变得比较宽，因此子带(Sub-Band)LBT被提出，即基站能仅针对LAA载波带宽中的一部分频带进行监听并发送无线信号。
发明内容
发明人通过研究发现：对于子带LBT，基站通过LBT可能发现一个LAA载波所包括的多个子带中仅有部分子带能够被用于无线发送；如果向传统的LTE LAA那样，基站立刻在所述部分子带上发送无线信号，则在MCOT(Maximum Channel Occupation Time，最大信道占用时间)结束之前基站无法在所述一个LAA载波上进行监听，进而无法利用其他子带发送无线信号。所述部分子带占所述一个LAA载波所包括的所有子带的比例越小，上述问题越导致传输效率的下降。
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，虽然本申请的初衷是针对子带LBT，本申请中的方法和装置也适用于宽带LBT以及在授权频谱上的通信。
