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。
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
在LTE(Long Term Evolution，长期演进)的LAA(License Assisted Access，授权辅助接入)项目中，基站和UE(User Equipment，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。
发明人通过研究发现，如果发送节点(比如基站或者UE)在做LBT时使用了某个波束，那只能假定这个波束方向上的信道是空闲的，而不能假定其他方向上的信道也空闲。基于这个现象，发送节点在这次LBT对应的burst(突发)中的传输将被限制在做LBT时使用的波束覆盖范围以内。这种限制可以被用来降低在每次burst中用于波束管理和指示的信令/反馈开销。
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，本申请的用户设备中的实施例和实施例中的特征可以应用到基站中，反之亦然。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。
本申请公开了被用于无线通信的用户设备中的方法，其特征在于，包括：

作为一个实施例，上述方法的特质在于：把非授权频谱上每次burst中使用到的波束限制在一个波束集合之内，所述M个信息集合中任一信息集合是用来在一个波束集合内指示波束相关的信息的，不同信息集合针对不同的波束集合。所述第二信令指示了当前burst对应 的波束集合，所述用户设备可以根据所述第二信令从所述M个信息集合中确定当前burst对应的信息集合。上述方法的好处在于，由于一个信息集合中的波束被限制在一个波束集合之内，而不是包括所有波束，用于指示一个信息集合中的某个信息元素所需要的比特的数量会被降低，从而降低了所述第三信令的开销。
作为上述实施例的一个子实施例，一个波束集合内的波束被限制在一次下行LBT使用的波束的覆盖范围之内。所述第二信令根据当前burst对应的下行LBT波束来确定所述第一信息集合。这种方法的好处在于，避免了对下行LBT波束以外的方向上正在进行的无线传输造成干扰。
根据本申请的一个方面，其特征在于，所述第一信令中用于指示所述M个信息集合中任意一个给定第一类索引的比特的数量小于所述第一信令中用于指示所述给定第一类索引所对应的第二类索引集合中的一个第二类索引的比特的数量。

作为一个实施例，上述方法的好处在于，在所述第二信令和所述第三信令之间建立了联系，避免所述用户设备对所述第三信令在所述M个信息集合中对应的哪个信息集合产生混淆。

-如果发送节点(比如基站或者UE)在非授权频谱上做LBT时发现某个波束方向上的信道是空闲的，其他方向上的信道不能被认为空闲，发送节点在这次LBT对应的burst(突发)中使用的波束集合将被限制在空闲的波束方向覆盖范围以内，从而避免了对非授权频谱上其他方向上正在进行的无线传输造成干扰。
-通过CC-RNTI标识的信令传递LBT波束相关的信息，并在CC-RNTI标识的信令和其他物理层信令之间建立联系，使UE能准确判断该使用哪个波束指示表格。
-允许UE在上行传输中使用超出下行LBT波束范围的波束，如果UE检测到使用的波束方向上的信道是空闲的。对下行LBT波束范围以外的上行波束采用比下行LBT波束范围以内的上行波束更严格的上行LBT。这种方法提高了调度的灵活性，同时避免了对下行LBT波束的范围之外的其他方向上正在进行的无线传输造成干扰。
