Description

一种被用于多天线通信的用户设备、基站中的方法和装置 技术领域
本申请涉及被用于多天线通信的方法和装置，尤其涉及物理层控制信令接收的方法和装置。
背景技术
现有的LTE(Long Term Evolution，长期演进)***中，对于一个下行子帧而言，E(User Equipment，用户设备)会在所述下行子帧中搜索对应的DCI(Downlink Control Information，下行控制信息)。下行授权(Grant)往往调度当前子帧的DL-SCH(Downlink Shared Channel，下行共享信道)，而上行授权往往调度后续子帧的UL-SCH(Uplink SharedChannel，上行共享信道)。***通过高层信令为UE分配两种不同的DCI格式(Format)，两种不同的DCI格式分别对应两种不同的负载尺寸(Payload Size)，UE在接收DCI时分别基于不同的负载尺寸进行盲检测(Blind Decoding)，且UE在给定载波上对应的最大盲检测次数是受限的。5G通信***中，波束赋形(Beamforming)将会被大量应用，而基于波束赋形应用场景下的DCI盲检测方法需要被重新考虑。
发明内容
5G***中，BR(Beam Recovery，波束恢复)以及BLF(Beam LinkFailure,波束链路失败)的概念正在被讨论中，UE检测当前的多个波束以获得动态调度，当UE检测的多个波束信道质量变差时，UE向基站发送BRR(Beam Recovery Request，波束恢复请求)以请求新的波束资源以监测物理层控制信令。
上述概念的引入是为了保证当UE发现一个波束对应的信道质量变坏时，所述UE能够快速切换到另外一个波束下被服务。上述BR及BLF的过程不会触发RRC(Radio1 Resource Control，无线资源控制)层的过程，此种方式的好处在于保证波束间切换的迅速。目前3GPP中已经定义，当UE发送BRR后，所述BRR中会携带UE推荐的波束信息，随后UE 会在推荐的波束上监测对应所述BRR的反馈。针对上述问题，考虑到其他针对非所述BRR的反馈的DCI的接收，一个简单的实现方式就是用户设备在不影响正常DCI的接收下针对BRR的反馈再增加正整数次盲检测，然而此种方法显然会增加UE的盲检测复杂度。
针对上述问题，本申请提供了解决方案。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。例如，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。
本申请公开了一种被用于多天线通信的用户设备中的方法，其特征在于包括：
-在第一时频资源集合中监测第一信令集合；
-发送第一无线信号；
-在第二时频资源集合和第三时频资源集合中分别监测第二信令集合和第三信令集合；
其中，所述第一信令集合、所述第二信令集合和所述第三信令集合分别包括M1个格式的物理层信令、M2个格式的物理层信令和M3个格式的物理层信令，所述M1、所述M2和所述M3分别是正整数；所述第一无线信号被用于触发针对所述第二信令集合的监测；所述第一无线信号被用于确定在所述第三时频资源集合中针对所述第三信令集合的最大盲检测的数量从X1变为X3，所述X1和所述X3分别为正整数，所述X1大于所述X3。
作为一个实施例，上述方法的好处在于：针对所述第二信令集合的盲检测不会增加UE整体的盲检测数，进而降低UE实现复杂度。
作为一个实施例，上述方法的另一个好处在于：当UE处于BR状态下时，即UE完成BRR的发送时，UE针对所述第三信令集合的盲检测次数变为X3次，有效降低UE的盲检测次数以降低UE的功耗。
作为一个实施例，上述方法的设计原理在于：当UE处于BR状态下时，UE用于物理层动态信令监测的波束的质量显然不好。在此场景下，所述用户设备调度机会也会较少，且需要更为鲁棒的物理层控制信令的传输，进而也不需要保留正常信道条件对应的控制信令候选(Candidate) 的数目。
根据本申请的一个方面，上述方法的特征在于，在所述第一时频资源集合中针对所述第一信令集合最多X1次盲检测被执行，在所述第二时频资源集合中针对所述第二信令集合最多X2次盲检测被执行，在所述第三时频资源集合中针对所述第三信令集合最多X3次盲检测被执行；所述第一信令集合所包括的RE的数量和所述第三信令集合所包括的RE的数量相同；所述X2是小于所述X1的正整数。
作为一个实施例，上述方法的好处在于：针对所述第三信令集合的控制信令候选所占用的时频资源均来自针对所述第一信令集合的控制信令候选所占用的时频资源，避免因为接收所述第二信令集合而导致分配额外的时频资源用于所述第三信令的监测。
作为一个实施例，上述方法的另一个好处在于：所述X2小于所述X1，针对所述第二信令集合的盲检测次数被限制，以降低UE的实现复杂度。
根据本申请的一个方面，上述方法的特征在于，所述第一时频资源集合所包括的RE在第一时频资源块中的图案和所述第三时频资源集合所包括的RE在第二时频资源块中的图案相同，所述第一时频资源集合和所述第三时频资源集合分别属于所述第一时频资源块和所述第二时频资源块，所述第一时频资源块和所述第二时频资源块占用相同的频域资源，所述第一时频资源块和所述第二时频资源块在时域上占用的时间长度相同。
作为一个实施例，上述方法的好处在于：所述第一时频资源集合对应第一搜索空间(Search Space)，所述第三时频资源集合对应第三搜索空间，所述第一搜索空间和所述第三搜索空间在各自对应的时频资源块中占用相同的RE，避免BR过程中引入新的RRC(Radio Resource Control，无线资源控制)信令的重新配置。
作为一个实施例，上述方法的好处在于：所述第一时频资源块对应第一CORESET，所述第二时频资源块对应第二CORESET，所述第一CORESET和所述第二CORESET占用相同的频域资源，以避免分配新的资源用于物理层动态信令的盲检测，降低控制信令的开销。
根据本申请的一个方面，上述方法的特征在于，所述X1次盲检测分 别针对X1个第一类RE集合，所述X3次盲检测分别针对X3个第二类RE集合，所述X3个第二类RE集合在第二时频资源块中的图案分别和X1个第一类RE集合中的X3个第一类RE集合在第一时频资源块中的图案相同，所述X1个第一类RE集合中的每一个所述第一类RE集合由正整数个RE组成，所述X3个第二类RE集合中的每一个所述第二类RE集合由正整数个RE组成。
作为一个实施例，上述方法的好处在于：所述第一类RE集合和所述第二类RE集合均针对同一类格式的DCI，保持所述图样的相同有助于简化控制信令的盲检测。
根据本申请的一个方面，上述方法的特征在于，所述X1个第一类RE集合中且所述X3个第一类RE集合之外的任意一个第一类RE集合中所包括的RE的数量小于或者等于所述X3个第二类RE集合中任一所述第二类RE集合中所包括的RE的数量。
作为一个实施例，上述方法的好处在于：当所述用户设备处于BR的状态时，针对所述BR状态下的所述第二类RE集合占用更多的RE，进而保证所述第三信令集合的鲁棒性。
根据本申请的一个方面，上述方法的特征在于，所述第一无线信号被用于确定第一天线端口组，所述第一天线端口组中包括正整数个天线端口，所述用户设备假定所述第二信令集合被所述第一天线端口组发送。
