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系统中的方法和装置。
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。3GPP RAN #78次全会决定了在NR Release 15中支持非授权频谱的接入。
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。根据3GPP RAN1 #92bis会议的讨论，在NR-U(NR-Unlicensed spectrum，NR非授权频谱)系统中，LBT以20MHz为单位。
发明内容
发明人通过研究发现，在带宽超过20MHz的频段上，以20MHz为单位进行LBT将导致系统可用频带和带宽的动态变化。为了不增加对下行控制信道的盲检测次数，调度信令中和资源分配相关的域要根据最大可能的带宽来设计。当实际可用带宽小于最大可能带宽时，这导致了控制信令开销的浪费。
针对上述问题，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。
本申请公开了一种被用于无线通信的用户设备中的方法，其特征在于，包括：
在第一资源粒子集合中接收第一信令；
在第一小区上接收第一无线信号；
其中，所述第一信令包括所述第一无线信号的调度信息；所述第一无线信号所占用的频率资源在所述第一小区所占用的频率资源内的位置与所述第一资源粒子集合有关。
作为一个实施例，本申请要解决的问题是：在非授权频谱上当由于sub-band(子带)LBT等原因导致系统可用频带和带宽的动态变化时，如何有效设计调度信令中和资源分配相关的域，避免当实际可用带宽小于最大可能带宽时控制信令开销的浪费。上述方法通过在被调度的数据所占用的频率资源和调度信令所占用的时频资源之间建立联系解决了这一问题。
作为一个实施例，上述方法的特质在于，所述第一资源粒子集合反映了当前系统可用的频带和带宽。所述第一无线信号所占用的频率资源在当前系统可用的频带和带宽之内分配。通过把所述第一无线信号所占用的频率资源和所述第一资源粒子集合相关联，可以降低资源分配所需要的信令开销，或者把所述第一信令中和资源分配相关的域中多余的比特设置成固定值用来帮助译码，从而提高所述第一信令的传输可靠性。
作为一个实施例，上述方法的好处在于：在基于sub-band(子带)LBT的非授权频谱上避免了由于系统可用频带和带宽的动态变化导致的控制信令开销的浪费。
根据本申请的一个方面，其特征在于，包括：

作为一个实施例，上述方法的好处在于，所述Q个资源粒子集合中不同的资源粒子集合所占用的频率资源可以对应不同的sub-band LBT，这样大大降低了由于一个UE的所有下行控制信道candidate都处于非空闲的频带上而导致的该UE无法被调度。
根据本申请的一个方面，其特征在于，所述Q个资源粒子集合中的任一资源粒子集合属于M个资源粒子池中的一个资源粒子池，所述第一资源粒子集合属于所述M个资源粒子池中的目标资源粒子池；所述M个资源粒子池中的任一资源粒子池包括所述Q个资源粒子集合中的正整数个资源粒子集合；所述第一无线信号所占用的频率资源在所述第一小区所占用的频率资源内的位置与所述目标资源粒子池有关；所述M是大于1的正整数。

作为一个实施例，上述方法的特质在于，所述第一信令的发送者可以灵活指示所述用户设备的active(活跃)BWP是否切换到所述第一无线信号所占用的BWP上。由于LBT的影响，所述第一信令的发送者无法保证所述第一无线信号所占用的BWP在下一个COT(Channel Occupy Time,信道占用时间)内任然能够被用于传输无线信号。上述方法的好处在于，可以允许UE始终在一个宽带的BWP上监测下行控制信道，降低了由于部分sub-band LBT失败而导致无法给UE发送下行控制信令的可能性。

在非授权频谱上当由于sub-band(子带)LBT等原因导致系统可用频带和带宽的动态变化时，根据调度信令所占用的频率资源来隐式指示数据信道所占用的频率资源的范围，避免了调度信令中和资源分配相关的域的开销的浪费。
UE在对应不同的sub-band LBT的频带上监测下行控制信道，大大降低了由于UE的所有 下行控制信道candidate都处于非空闲的频带上而导致的该UE无法被调度。
