Description

无线通信系统中的用户设备、电子设备、方法及存储介质
本申请要求于2019年8月15日提交中国专利局、申请号为201910753424.8、发明名称为“无线通信系统中的用户设备、电子设备、方法及存储介质”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本公开涉及无线通信的技术领域，具体地涉及无线通信系统中的用户设备、电子设备、用于在无线通信系统中进行无线通信的方法以及计算机可读存储介质。
背景技术
在目前的无线通信系统中，网络侧会为UE(User Equipment，用户设备)配置一个PCell(Primary Cell，主小区)和多个SCell(Secondary Cell，辅小区)以与基站通信。针对每个SCell，UE会进行波束失败检测，以判断该SCell所使用的波束是否处于失败状态。如果发生了波束失败，UE会向网络侧告知波束失败事件，并且会告知发生波束失败的SCell的标识和UE选择的新的波束。在这之后，网络侧会使用UE选择的新的波束来发送信号。当UE接收到该信号时，可以认定新的波束已经启用，亦即波束失败恢复成功。
在第五代移动通信系统(5G)的NR(New Radio，新无线)系统中，通信传输在高频段运行。由于毫米波传播环境的变化，如人和建筑物的阻挡、UE的旋转等因素，UE和网络之间的波束有可能会频繁出现波束失败的情况。另外，当UE被配置多个SCell时，多个SCell有可能是共址的，亦即使用相同的下行发射波束。因此，如果发生波束失败的话，有可能多个辅小区同时发生波束失败。而每当一个辅小区发生波束失败时，UE都会向网络侧告知一个波束失败事件，以及相应地告知发生波束失败的SCell的标识和UE选择的新的波束。这样一来，造成通信传输的开销较大。
因此，有必要提出一种技术方案，以在辅小区发生波束失败时减少 通信传输的开销。
发明内容
这个部分提供了本公开的一般概要，而不是其全部范围或其全部特征的全面披露。
本公开的目的在于提供一种无线通信系统中的用户设备、电子设备、用于在无线通信系统中进行无线通信的方法以及计算机可读存储介质，以在辅小区发生波束失败时可以减少通信传输的开销。

具体实施方式
现在参考附图来更加充分地描述本公开的例子。以下描述实质上只是示例性的，而不旨在限制本公开、应用或用途。
提供了示例实施例，以便本公开将会变得详尽，并且将会向本领域技术人员充分地传达其范围。阐述了众多的特定细节如特定部件、装置和方法的例子，以提供对本公开的实施例的详尽理解。对于本领域技术人员而言将会明显的是，不需要使用特定的细节，示例实施例可以用许多不同的形式来实施，它们都不应当被解释为限制本公开的范围。在某些示例实施例中，没有详细地描述众所周知的过程、众所周知的结构和众所周知的技术。
本公开所涉及的UE(User Equipment，用户设备)包括但不限于移动终端、计算机、车载设备等具有无线通信功能的终端。进一步，取决于具体所描述的功能，本公开所涉及的UE还可以是UE本身或其中的部件如芯片。此外，类似地，本公开中所涉及的基站可以例如是eNB(evolution Node Base Station，演进节点基站)，也可以是gNB(第5代通信系统中的基站)，或者是eNB或gNB中的部件如芯片。
在目前的无线通信系统中，网络侧会为UE(User Equipment，用户设备)配置一个PCell(Primary Cell，主小区)和多个SCell(Secondary Cell，辅小区)以与基站通信。针对每个SCell，UE会进行波束失败检测，以判断SCell所使用的波束是否处于失败状态。如果发生了波束失败，UE会向网络侧告知波束失败事件，并且会告知发生波束失败的SCell的标识和UE为恢复SCell服务而选择的新的波束。在此之后，网络侧会使用UE选择的新的波束来发送信号。当UE接收到该信号时，可以认定新的波束已经启用，亦即波束失败恢复成功。
图1示出了发明人已知的一种UE和网络侧之间的波束失败恢复流程的示意图。其中，UE经由一个具有上行链路的PCell或SCell和一个仅具有下行链路的SCell与基站进行通信。
如图1所示，例如，具有上行链路的PCell或SCell可以向UE发送针对BFD(Beam Failure Detection，波束失败检测)的q0集合(Reference Signal Set，参考信号集合)。仅具有下行链路的SCell可以设置以显式或隐式的方式针对BFD配置的q0。例如，对于显式的配置方式，q0这个参考信号集合可以是gNB通过RRC(Radio Resource Control，无线资源控制)信令为UE在每一个SCell上配置的最多2个周期性的CSI-RS(Channel State Information Reference Signal，信道状态信息参考信号)资源。在没有显式的配置方式的情况下，可以采用隐式的配置方式。对于隐式的配置方式，UE可以自己来决定q0集合中包含的参考信号，这个参考信号与 PDCCH(Physical Downlink Control Channel，物理下行控制信道)所在的CORESET具有相同的TCI(Transmission Configuration Indication，传输配置指示)状态(亦即相同的波束方向)。
然后，UE可以基于q0来判断是否发生波束失败事件。例如，UE可以根据q0中的参考信号来判断该参考信号对应的PDCCH的假设BLER(Block Error Rate，块错误率)是否过高，从而判断该波束是否处于失败的状态。假设发生了波束失败事件，UE可以向具有上行链路的PCell或SCell发送PUCCH(Physical Uplink Control Channel，物理上行控制信道)来告知波束失败事件。例如，UE可以在PUCCH中发送BFRQ(Beam Failure Recovery Request，波束失败恢复请求)。
然后，具有上行链路的PCell或SCell可以授权PUSCH(Physical Uplink Shared Channel，物理上行共享信道)承载MAC CE(Media Access Control-Control Element，媒体接入控制-控制元素)。接下来，UE可以通过MAC CE来告知发生波束失败的小区ID(Identification，标识)和UE选择的新波束。最后，UE在一个特定的PDCCH搜索空间中，即RecoverySearchSpace恢复搜索空间中接收用新波束发来的PDCCH，以此来认定新波束已经启用，即波束失败恢复成功。
然而，当UE被配置多个SCell时，多个SCell有可能是共址的，亦即该多个SCell使用相同的下行发射波束。因此，如果发生波束失败的话，有可能使用该失败波束的多个SCell同时发生波束失败。而每当一个SCell发生波束失败时，UE都会向网络侧告知一个波束失败事件，以及相应地告知发生波束失败的SCell的ID和UE选择的新的波束。这样一来，造成通信传输的开销较大。
图2示出了发明人已知的另一种UE和网络侧之间的波束失败恢复流程的示意图。其中，UE经由一个具有上行链路的PCell或SCell和两个仅具有下行链路的SCell A和B与基站进行通信。
如图2所示，例如，具有上行链路的PCell或SCell可以向UE发送针对BFD的q0。仅具有下行链路的SCell A和B可以设置以明示或默示的方式针对BFD配置的q0。然后，UE可以分别基于从SCell A和SCell B接收的q0来判断SCell A和SCell B是否发生波束失败事件。假设发生了波束失败事件，UE可以向具有上行链路的PCell或SCell分别发送针对SCell A和SCell B的PUCCH来告知波束失败事件。然后，具有上行链路的PCell或SCell可以授权PUSCH分别承载针对SCell A和SCell B的 MAC CE。接下来，UE可以分别通过针对SCell A和SCell B的MAC CE来告知发生波束失败的小区ID和UE选择的新波束。最后，UE分别在一个特定的PDCCH搜索空间中，即针对SCell A的恢复搜索空间A和针对SCell B的恢复搜索空间B中接收用新波束发来的PDCCH，以此来认定新波束已经启用，即波束失败恢复成功。具体地，如果在恢复搜索空间A中接收到了相应的波束，则认为SCell A的波束恢复成功；反之，如果在恢复搜索空间A中未接收到相应的波束，则认为SCell A的波束未恢复成功。对于SCell B的波束恢复类似，就不再重复赘述了。
然而，多个SCell共址的情况下，例如上述共址的SCell A和SCell B，UE没有必要去对每个SCell的恢复搜索空间A和恢复搜索空间B进行搜索从而确认新波束的启用。
为了解决上面提到的问题中至少之一，提出了根据本公开的技术方案。图3示出了根据本公开的实施例的无线通信系统中的UE 300的结构。
如图3所示，UE 300可以包括处理电路310。需要说明的是，UE 300既可以包括一个处理电路310，也可以包括多个处理电路310。另外，UE 300还可以包括通信单元320等。
进一步，处理电路310可以包括各种分立的功能单元以执行各种不同的功能和/或操作。需要说明的是，这些功能单元可以是物理实体或逻辑实体，并且不同称谓的单元可能由同一个物理实体实现。
根据本公开的一个实施例，如图3所示，处理电路310可以包括判断单元311和设置单元312。
判断单元311可以被配置为判断多个辅小区中的每一个是否发生波束失败。
然后，当判断单元311判断所述多个辅小区中的至少两个已发生波束失败时，设置单元312可以被配置为设置单个媒体接入控制的控制元素MAC CE以通知网络侧波束失败事件。
根据本公开的一个实施例，MAC CE可以包含发生波束失败的所有CC(Component Carrier，分量载波)的索引信息。这里，本领域技术人员应该清楚，本公开并不限于此，MAC CE当然可以包括其他例如UE选择的新波束等信息。
例如，根据本公开的一个实施例，如图4所示，处理电路310可以进一步包括选择单元313。
选择单元313可以被配置为针对发生波束失败的每个辅小区，基于波束失败恢复的候选参考信号集合q1选择新的波束。根据本实施例，MAC CE还可以包含UE选择的新的波束的标识信息。这里，新的波束的标识信息与失败的CC的索引信息相对应。
如图5A所示，其中示意性示出3个MAC CE，每一个MAC CE以8位表示。每一个MAC CE前5位用于表示失败的CC索引信息，后3位表示新波束ID。然而，如果多个SCell A1到Am是准共址的关系，即具有相同的下行发射波束关系，并且选择了相同的新波束A，多个SCell B1到Bm是准共址的关系，并且选择了相同的新波束B，那么，多个MAC CE可以省略到单个MAC CE，从而可以缩减MAC CE的有效载荷。
例如，如图5B所示，其中，失败的CC索引A1到失败的CC索引Am可以被划分为一组，而MAC CE可以被设置使得该组中的多个索引A1...Am对应于单个新波束ID A。类似地，失败的CC索引B1到失败的CC索引Bm可以被划分为一组，而MAC CE可以被设置使得该组中的多个索引B1...Bm可以对应于单个新波束ID B。由此，可以缩减MAC CE的有效载荷。
为了对MAC CE进行更合理的安排，根据本公开的一个实施例，设置单元312还可以被配置为设置所述MAC CE，使得所述MAC CE包含指示组的长度的信息。
考虑到目前协议只支持两个不同站址的传输，也就假设相应地分为两个组来进行恢复，分别是组A和组B。当然，本领域技术人员应该清楚，也可以扩展到多于两个组的情况。
例如，如图6所示，可以在每一个MAC CE上报的开头设置每个组例如A组的波束失败的SCell的数目，接下来，上报失败的CC索引信息A1...Am，最后，加上一个新波束的ID A。接下来，上报B组的波束失败的SCell的数目，然后，上报失败的CC索引信息B1...Bm，最后，加上一个新波束的ID B。
相应地，当多个SCell是准共址的关系时，根据本公开的一个实施例，网络侧也可以采用分组的方式来向UE发送BFRR(Beam Failure Recovery Response，波束失败恢复回复)。
例如，图7示出了网络侧采用分组的方式来向UE发送BFRR的示意图，其中，仅具有下行链路的SCell A1...Am为一组，这里称为A组； 仅具有下行链路的SCell B1...Bm为一组，这里称为B组。网络侧可以选择针对A组和B组中的每一组SCell发送一个BFRR的PDCCH，从而减少网络侧下行的信令开销。例如，网络侧可以向UE发送针对A组的一个BFRR的PDCCH。网络侧也可以向UE发送针对B组的一个BFRR的PDCCH。
接下来，SCell A1...Am一组即A组具有相同的新波束，SCell B1...Bm一组即B组具有相同的新波束。那么，如果UE可以在其中一组的任何一个SCell内找到恢复搜索空间中的PDCCH，UE则认为该组SCell的波束失败恢复成功。例如，如果UE在A组的SCell A1内找到恢复搜索空间中的PDCCH，UE则认为A组中的所有SCell的波束失败恢复成功。如果UE在B组的SCell B1内找到恢复搜索空间中的PDCCH，UE则认为B组中的所有SCell的波束失败恢复成功。
另外，这里本领域技术人员应该清楚，即使网络侧没有采用分组的方式来向UE发送BFRR即网络侧为每组中的每一个SCell都发送一个BFRR，UE同样可以针对每组只要找到一个恢复搜索空间中的PDCCH，就可以认为该组中的所有SCell的波束失败恢复成功。以此方式，可以避免UE进行额外的下行控制信道的忙检测。
不同于在多个SCell中向UE发送BFRR的技术方案，PCell也可以为多个SCell向UE发送BFRR。
如图8所示，PCell向UE发送BFRR可以分为两部分，部分1和部分2。在部分1中，与在多个SCell中向UE发送BFRR的情况类似，UE只要在PCell的恢复搜索空间如RecoverySearchSpaceForSCell中找到PDCCH即认定新波束已经启用，即波束失败恢复成功。
而在部分2中，为了节省开销，PDCCH调度的PDSCH(Physical Downlink Shared Channel，物理下行共享信道)资源可以是无效(invalid)资源，如将该调度的PDSCH的频域资源配置为0RB或者时域资源的OFDM符号数配置为0。
然而，为了BFRR中包含更多维度的信息，如图9所示，在部分1中，类似地，UE只要在PCell的恢复搜索空间中找到PDCCH即认定波束失败恢复成功。而在部分2中，PDCCH调度的PDSCH用来承载更多的信息给UE。例如，在PCell发送的BFRR所包含的MAC CE中可以指示UE为每一个SCell选择的新波束网络侧是否接受。如果网络侧不接受， 网络侧将给出新波束的ID，例如CSI-RS资源索引或SSB索引。这里，针对PCell的MAC CE的格式可以与图5A所示的类似，每一个MAC CE可以以8位表示，每一个MAC CE前5位用于表示失败的CC索引信息，后3位表示新波束ID。
如上所述，对于每一个SCell，UE可以被配置q0和q1两个参考信号集合。其中，q0为波束失败检测的参考信号集合；ql为波束失败恢复的备选参考信号集合。而当UE在q1中没有找到符合质量要求的新波束的情况下，UE可以向网络侧上报指示不存在新波束的信息，并且UE可以通过网络侧触发的非同步的下行波束扫描过程，重新选择新波束。
如图10所示，在BFRQ过程中，如果当UE在q1中没有找到符合质量要求，例如L1-RSRP(Lay 1-Reference Signal Receiving Power，层1-参考信号接收功率)在某一个特定的门限之上的新波束时，UE可以上报给网络侧一个新波束的特殊状态。根据本公开的优选实施例，这个特殊状态可以在PUCCH中上报。当网络侧收到这个特殊状态的上报后，可以选择通过DCI来触发非同步的下行波束扫描过程。UE在测量了下行波束后，可以反馈给网络侧波束质量最好的波束作为新波束。
而当UE发现q1已经没有备选波束在L1-RSRP门限之上的新波束时，即使这时q0中的波束质量仍然较好，UE仍然可以通过PUCCH/PUSCH告知网络侧该情况，并请求一次非周期的波束扫描和上报，如图11所示。
对于目前的协议，只有当q0中的全部波束都质量较差时，才算一个BFR事例。但是，如图12所示，Tx波束1和Tx波束2对应的RS都在q0集合中，但是Tx波束1的质量较差。在这种情况下，UE并不会上报BFR事例给MAC CE，因为Tx波束2的波束质量始终较好。
因此，为了解决上述问题，根据本公开的一个实施例，基于波束失败检测的参考信号集合q0确定部分波束失败状态，在所述部分波束失败状态下，在所述q0中仅有一部分参考信号处于信道条件恶劣状态，UE也会向网络侧上报指示所述一部分参考信号处于信道条件恶劣状态的信息，并且UE可以基于来自网络侧的消息重新设置所述q0。
例如，如图13所示，当UE检测q0中的部分RS处于不良的信道条件时，可以向网络侧上报更新/改变q0中该部分RS对应的CORESET波束。然后，网络侧下发RRC重新配置信令或通过MAC CE激活。接下来，UE通过PUCCH承载ACK，以表示成功接收网络侧下发的RRC重新配 置或MAC CE激活。
根据本公开的一个实施例，网络侧可以包括基站或TRP(Transmit/Receive port，发送/接收端口)。
使用根据本公开的无线通信系统中的用户设备可以在辅小区发生波束失败时减少通信传输的开销。
接下来将结合图14来描述根据本公开的另一实施例的无线通信系统中的电子设备1400。
图14示出了根据本公开的另一实施例的无线通信系统中的电子设备1400的结构。
如图14所示，电子设备1400可以包括处理电路1410。需要说明的是，电子设备1400既可以包括一个处理电路1410，也可以包括多个处理电路1410。另外，电子设备1400还可以包括诸如收发机之类的通信单元1420等。
如上面提到的那样，同样地，处理电路1410也可以包括各种分立的功能单元以执行各种不同的功能和/或操作。这些功能单元可以是物理实体或逻辑实体，并且不同称谓的单元可能由同一个物理实体实现。

需要说明的是，根据本公开的实施例，如上所述的无线通信系统可以是5G新无线NR系统，并且电子设备1400可以是基站或TRP。

另外，需要说明的是，根据本公开的另一实施例，还提供了一种计算机可读存储介质，该存储介质可以包括可执行计算机指令，所述可执行计算机指令当被计算机执行时使得计算机可以执行根据本公开的实施例所述的方法。
