技术领域
本公开涉及一种无线通信系统中的电子设备和方法，并且具体而言，涉及无线通信系统中进行信息传输的电子设备和方法。
背景技术
随着移动互联网技术的发展和广泛应用，无线通信前所未有地满足了人们的语音和数据通信需求。随着使用频段的增加(比如26GHz、60GHz或者更高的频段)，无线信道必将承受比低频段(如2GHz)更大的路径损耗、大气吸收损耗等负面影响。为了提供更高的通信质量和容量，无线通信系统采用了不同层面的各种技术。
近年来，大规模多输入多输出(Massive Multi-Input Multi-Output,MIMO)技术和毫米波(Millimeter Wave)技术被认为是未来5G关键技术的一部分，引起了学术界和工业界的广泛关注。毫米波频段具有大量可用频谱资源，能够满足移动通信日益增长的业务流量需求。此外，由于毫米波的波长较短，根据天线理论，毫米波系统的天线尺寸也较小，使得能够在小范围空间中放置几百甚至上千根天线，更有利于大规模天线技术在现实系统中的应用。
此外，在大规模天线技术中，通过波束赋形(Beam forming)技术能有效弥补毫米波信道路径衰落过大的缺点，为毫米波技术应用于移动通信提供了可能。波束赋形可以通过增加天线发射和/或接收的指向性，提供波束赋形增益以补偿无线信号的损耗。为此，3GPP在5G的标准制定中引入了波束管理(Beam Management)的概念，其中介绍了用于通信的波束的确定和应用。

虽然在本公开内容中所描述的实施例可能易于有各种修改和另选形式，但是其具体实施例在附图中作为例子示出并且在本文中被详细描述。但是，应当理解，附图以及对其的详细描述不是要将实施例限定到所公开的特定形式，而是相反，目的是要涵盖属于权利要求的精神和范围内的所有修改、等同和另选方案。
具体实施方式
在下文中将结合附图对本公开的示范性实施例进行描述。为了避免因不必要的细节而模糊了本公开，在附图中仅仅示出了与至少根据本公开的方案密切相关的处理步骤和/或设备结构，而省略了与本公开关系不大的其他细节。此外，还应注意，在附图中相似的附图标记和字母指示相似的项目，并且因此一旦一个项目在一个附图中被定义，则对于随后的附图无需再对其进行论述。
为了清楚和简明起见，在说明书中并未描述实施例的所有特征。然而，应该了解，在对实施例进行实施的过程中必须做出很多特定于实施方式的设置，以便实现开发人员的具体目标，例如，符合与设备及业务相关的那些限制条件，并且这些限制条件可能会随着实施方式的不同而有所改变。此外，还应该了解，虽然开发工作有可能是非常复杂和费时的，但对得益于本公开内容的本领域技术人员来说，这种开发工作仅仅是例行的任务。
典型地，无线通信系统或者无线电系统至少包括发射侧和接收侧，发射侧设备与接收侧设备通过信号流的发送与接收来进行通信。在本公开中，无线通信系统或无线电系统的“发射侧”具有其通常含义的全部广度，通常指示系统中发射信号流以进行通信和/或控制的一侧，其也可以被称为系统中的信号“控制侧”，并且在本公开的上下文中可互换地使用。类似地，术语“接收侧”具有其通常含义的全部广度，相应地可以指示系统中接收信号流以进行的通信和操作的一侧，其也可以被称为系统中的信号“终端侧”，并且在本公开的上下文中可互换地使用。
作为示例，依赖于通信系统中信号流的方向和/或通信系统中的操作控制，“发射侧”和“接收侧”可包含通信系统中的不同设备。例如对于下行信号传输，“发射侧”设备可以包括无线通信系统(诸如蜂窝式通信系统、V2X系统等)中的基站、控制设备、服务器或MEC、中继器或路边单元(RSU)等等，而“接收侧”设备可以相应地包括通信系统中的终端设备。反之，对于上行信号传输，“发射侧”设备可以包括 通信系统中的终端设备，而“接收侧”设备可以相应地包括通信系统中的基站等等。
在本公开中，术语“基站”具有其通常含义的全部广度，并且作为例子，基站例如可以是遵循4G通信标准的eNB、遵循5G通信标准的gNB、远程无线电头端、无线接入点、飞行器控制塔台或者执行类似功能的通信装置。
在本公开中，术语“终端设备”具有其通常含义的全部广度，并且至少包括作为无线通信系统或无线电系统的一部分接收来自发射侧设备的信号以便于通信的终端设备。作为例子，终端设备例如可以是无线中继、微基站、路由器、用户设备等之类的终端设备或者执行类似功能的通信装置。在本公开中，“终端设备”和“用户设备(UE)”可以互换地使用，或者“终端设备”可以与“用户设备”结合在一起或者实现为“用户设备”的一部分。在本公开中，术语“用户设备(UE)”具有其通常含义的全部广度，并且作为例子，用户设备例如可以是移动电话、膝上型电脑、平板电脑、车载通信设备等之类的终端设备或者执行类似功能的通信装置。
在当前5G无线通信系统中，特别在毫米波技术领域中，发射侧设备(诸如基站)往往利用天线来形成方向性波束以用于与接收侧设备(诸如终端设备)之间进行通信。特别地，在无线通信系统、尤其是毫米波通信系统中，通常采用每条射频链路连接多个移相器及天线而利用少至一条射频链路形成具有指向性的波束，并且通过波束赋形方案来找到发射侧设备与接收侧设备之间匹配的波束对，以便用于后续的无线通信。作为示例，以下行链路为例，通过基站的发送波束与用户设备的接收波束之间的波束扫描来进行下行波束赋形训练以获得用于下行链路的波束对，即找到由最优的基站发送波束和最优的用户设备接收波束构成的一组最优的波束对。类似地，在上行链路中，基站的接收波束与用户设备的发送波束也构成一组波束对。
然而，在5G通信系统中，发射侧设备与终端设备之间的波束通信的开销值得关注，尤其是当发射侧设备(诸如基站)往往服务于多个终端设备(诸如移动用户设备)时，针对基站与多个用户设备的通信的波束管理的信令开销尤其值得关注。在当前的技术中，基站与每个用户设备之间的波束管理是通过两者之间的单独信令交互而进行，这样基站往往需要进行多次重复性的信令操作，波束管理中的信令开销高。
鉴于此，本公开研究了5G通信系统中通过将终端设备分组来减少波束管理中的信令开销。特别地，本公开提出了基于终端设备分组的波束管理，其中一个或多个终端设备被分到同一个终端设备组，并且对于每个终端设备组，使用一个波束来进行发射侧设备与该终端设备组中的各个终端设备之间的通信操作，例如波束扫描、组标识 信息传输、组共享波束信息传输、终端设备接收波束的确定等等，以及为该终端设备组中的各个终端设备提供服务。这样，当5G系统运行在毫米波频段时，通过多个信道或信号使用相同的波束，可以在满足可靠性的前提下减少不必要的信令开销和时延。特别地，基于组共享波束，能够通过较少的波束操作和信令传输来减少基站与UE之间的波束管理的开销。
以下将主要以基站作为发射侧设备/控制侧设备的示例、以及以用户设备作为接收侧设备/终端侧设备的示例，在基站与用户设备的下行链路通信场景下来描述根据本公开的技术方案。应指出，以下虽然主要基于包含基站和用户设备的通信系统对本公开的实施例进行了描述，但是这些描述可以相应地扩展到包含任何其它类型的控制侧和终端侧的通信系统的情况。而且，这些描述的操作同样可以应用于上行链路通信场景。
特别地，当一些用户设备聚集在一起的时候，基站可以使用相同的下行波束来为构成用户设备组的这些用户设备进行服务。例如，当多个用户设备聚集在车辆或者列车车厢内时，车辆或者列车车厢内的用户设备可被分为一组，并且基站可以使用相同的下行波束服务于列车或者列车车厢内的这组用户设备。
作为示例，图1示出列车环境下的发射侧/控制侧设备与接收侧/终端侧设备之间的通信场景。其中，发射侧设备可包括图中所示的BBU(基带处理单元)，RRU(远端射频单元)等中的至少一个，其用于控制与列车中的设备进行通信，而终端设备可包括图中所示的CPE(前置设备)以及列车上的用户设备等中的至少一个。其中，一辆列车、甚至是一个车厢中的终端设备可以作为终端设备组与发射侧设备进行通信。此外，列车中的车厢之间、车队中的相邻车辆之间以及车辆与头车之间可实现信息共享。例如，可以通过利用直通链路通过组播的方式在车队中进行信息分享。上述通信场景同样适用于利用直通链路(sidelink)组播通信的其它各种无线通信场景中，例如智能工厂机器人编队操作等等。
以下将参照附图示意性地描述根据本公开的实施例的基于用户设备分组的波束管理。图2A示出了根据本公开的实施例的基于分组的波束管理过程200的概念性流程图。
在步骤201，实现用户设备的分组。根据本公开的实施例，可以根据无线通信系统中的用户设备的位置信息来对用户设备进行分组。特别地，作为示例，位置彼此接近的用户设备可被分为一组，例如被分为一组的用户设备之间的距离往往会小于特定 阈值。
根据本公开的实施例，用户设备的分组可以由与用户设备通信的基站来进行。特别地，基站可以获取其服务的用户设备各自的位置信息，并且根据位置信息来将用户进行分组。用户设备的位置信息可以由用户设备上报给基站，例如通过GPS系统上报；或者用户设备向基站发送与定位相关的信息以便基站能够根据该信息来估计出用户设备的位置，例如通过发送上行的以定位为目标的SRS，使得基站可以估计出用户设备的位置；或者用户设备的位置信息可以由系统中的其它设备获知，并且基站可以从该其它设备获知用户设备的位置信息，从而可以基于该位置信息来实现用户设备的分组。
根据本公开的实施例，用户设备的分组可以由系统中的其它设备实现，并且基站可以从该其它设备获知用户设备的分组信息。作为示例，无线通信系统中的其它控制设备、接入点等可获得用户设备的位置并且进行分组，然后将分组信息告知基站。例如，在V2X中，路侧单元可参与车辆的分组并且将车辆分组信息告知基站。
根据本公开的实施例，用户设备的分组信息可以由基站获知并且告知用户设备，或者可以由系统中实现用户设备分组的其它设备来告知用户设备，以便用户设备能够知晓自己的分组状况。
在步骤202，获取基站与用户设备组之间的通信所使用的组共享波束。根据本公开的实施例，组共享波束指的是基站与用户设备组中的各个用户设备进行通信所使用的公共波束，这样基站可以对于用户设备组所包含的多个用户设备使用一个公共波束，从而有效地节省了通信开销。
根据本公开的实施例，通过基站与用户设备组中的特定用户设备之间的波束扫描来获取组共享波束。波束扫描可以采用各种方式来实现。图2B示出了根据本公开的实施例的波束扫描操作的示意图，其中基站采用具有指向性的数个发送波束与用户设备的具有多个指向性的数个接收波束进行通信，以形成多个波束对，如(a)所示。然后选择这些波束对中的通信质量最优的波束对作为所希望的发送波束与接收波束对，如(b)所示，以用于后续的基站与用户设备之间的通信。应指出，图2B所示的用于波束管理的波束扫描仅仅是示例性的，基站与用户设备之间的波束配对可以采用各种适当的方式来进行。例如，基站和用户设备之一可以采用全向天线进行波束配对；基站和用户设备可以分别采用水平波束和垂直波束来进行波束配对，等等，这里将不在详细描述。
在步骤203，获取基站与用户设备组中的各个用户设备之间的通信用波束。特别地，虽然基站可以使用相同的下行波束来给用户设备发送数据信道、控制信道和下行参考信号，但用户设备所处的位置和设备姿态不一致，需要使用各自的接收波束来进行接收。
根据本公开的实施例，基站可以采用之前获取的组共享波束来分别与各个用户设备进行波束扫描操作，继而进一步获取基站与各个用户设备进行通信的波束对，尤其是用户设备的接收波束。这样的波束对确定操作中，基站仅需要采用一个公共波束进行波束扫描，有效地降低了操作开销。这里波束扫描操作可以按照上文所述的波束扫描操作的方式来进行。
图2C示出了根据本公开的实施例的控制侧和终端侧的基于分组的波束管理的结果的示意图。其中，基站所服务的小区域内的用户设备分成两个组，UE组1和UE组2。并且，基站使用公共的下行发射(Tx)波束(也就是组共享波束)来给用户设备组发送数据信道，控制信道和下行参考信号，而用户设备使用各自的接收波束来进行接收。
由此，通过用户设备分组并且基于分组进行波束管理，尤其是使用公共的组共享波束，至少可以降低操作中基站侧的波束操作开销，从而有效地降低操作开销和信令交互开销，改进系统通信性能。
以下将描述根据本公开的实施例的发射侧电子设备和接收侧电子设备的实现。在本公开中，“发射侧电子设备”具有其通常含义的全部广度，例如可以包括作为无线通信系统或无线电系统的一部分以便发射信号进行通信和控制的设备，并且可以与“控制侧电子设备”互换地使用。在一些实施例中，发射侧电子设备可以是发射侧设备或者该发射侧设备的一部分。在本公开中，术语“接收侧电子设备”具有其通常含义的全部广度，并且至少包括被用于作为无线通信系统或无线电系统的一部分以接收信号进行通信或操作的设备，并且可以与“终端侧电子设备”互换地使用。在一些实施例中，接收侧电子设备可以是接收侧设备(即终端设备)或者该接收侧设备的一部分。
图3示出了根据本公开的实施例的发射侧电子设备300的示意性框图。发射侧电子设备300可以与无线通信系统中的接收侧电子设备进行通信，特别地进行波束通信。
如图3所示，发射侧电子设备300可以包括处理电路320。根据本公开的实施例，处理电路320可以被配置为：确定用于与无线通信系统中的终端设备组进行通信的组 共享波束，所述终端设备组包括多个终端设备；以及利用所确定的组共享波束将组共享波束的相关信息发送给所述终端设备中的至少一个终端设备。
如前文所述，终端设备的分组可以由系统中的适当设备基于终端设备的位置来实现。根据本公开的实施例，该终端设备的分组可以由发射侧设备来进行，特别地，发射侧电子设备的处理电路可基于所获取的无线通信系统中的终端设备的位置信息来对终端设备进行分组。作为示例，如前文所述地，终端设备的位置信息可直接获取或者估计得到。
根据本公开的实施例，发射侧电子设备的处理电路可以通过信令将分组信息告知终端设备，例如可以通过无线资源控制(RRC)或者媒体接入控制(MAC)信令将无线通信系统中的每个终端设备的分组信息告知该终端设备。这样，对于一个终端设备而言，该终端设备可以明了自己处于哪个分组中。
根据本公开的分组状况可以采用适当的信息来指示。根据本公开的实施例，该分组信息可以是指示终端设备组别的标识，特别地，所述分组信息可以包括该终端设备所属的设备组的无线网络临时识别码(RNTI，Radio Network Temporary Identifier)。
作为一个示例，发射侧设备可以经由RRC(Radio Resource Control,无线资源控制)层的信令来传输RNTI告知终端设备属于哪个分组。这尤其适合于终端设备属于一个组的情况。
应指出，还存在终端设备可能属于多于一个以上的组的情况。例如，终端设备可能同时属于两个组，或者通过移动而先后属于不同的组。作为另一示例，如果终端设备属于多于一个分组，则发射侧设备可以使用更下层的MAC(Media Access Control,媒体接入控制)信令或物理层信令，如MAC CE(Media Access Control-Control Element,媒体接入控制-控制元素)或DCI(Downlink control information,下行控制信息)来传输RNTI以告知终端设备所属的分组，和/或还可以通知终端设备进行分组的调整。例如，当终端设备由于移动而改变分组状况时，发射侧设备可以通过MAC-CE或DCI来将分组的变更告知终端设备。
图4示出了UE可以属于两个分组以及移动的情景。对于图4中处于两个分组交界的UE，基站可以将其分配进入两个分组，即组1和组2，并分别分配组共享(GC，GroupCommon)RNTI，即GC-RNTI 1和GC-RNTI 2。并且可以根据UE和基站的状况来改变分配给该UE的GC-RNTI的状态。
特别地，当UE从组1移动到组2的时候，基站可以通过MAC CE来更改UE的分 组，即去激活掉GC-RNTI 1并且激活GC-RNTI 2。作为另一示例，如果该UE具备较强的波束赋型能力，其可以同时被组1和组2服务，即所分配的GC-RNTI 1和GC-RNTI2都处于激活的状态。这取决于UE的上报能力和基站对应的配置。
在确定UE分组之后，可以基于该分组进行基站与用户设备之间的波束管理，以便确定用于基站与用户设备之间进行通信的波束。特别地，确定用于与用户设备组进行通信的组共享波束，从而基站采用该组共享波束作为发送波束与用户设备组中的各个用户设备进行通信，而各个用户设备可以采用相应的接收波束进行接收通信。
根据本公开的实施例，发射侧电子设备的处理电路进一步配置为通过控制侧设备与终端设备组中的关键终端设备进行波束扫描来确定所述组共享波束。特别地，关键终端设备指示作为该终端设备组的代表与发射侧电子设备进行通信的特定设备，该关键终端设备可以是终端设备组中的一个终端设备，或者可以是与该终端设备组相关联的一个设备，例如在一辆列车中的终端设备作为一个终端设备组的情况下的该列车的CPE，等等。
根据本公开的实施例，关键终端设备可以采用各种方式被适当地确定。根据一个实施例，关键终端设备是基于终端侧设备的通信能力被选定的。作为一个示例，终端设备组中的功率、天线尺寸、信道条件最优的终端设备，可以作为关键终端设备。作为另一个示例，与该终端设备组相关联的一个设备由于其更好的通信能力而作为关键终端设备。例如，在列车应用场景中，架设在车顶的CPE往往比列车内的一般UE具有功率，天线尺寸，信道条件上的优势，可作为关键设备，负责列车内的用户设备组与基站之间的通信。
根据一个实施例，所述关键终端设备可以被静态或者半静态地确定。例如，关键终端设备被确定并且在基站与终端设备之间进行通信器件保持不变。
根据另一个实施例，关键终端设备是动态确定的。特别的，关键终端设备是终端设备组中的多个终端设备之间轮询地确定的。该轮询可通过各种方式来执行。作为示例，通过在多个终端设备之间比较各个终端设备之间的性能，诸如功率、信道条件等等，选择具有最佳性能的终端设备作为关键终端设备。当然，还可以参照其它性能条件来进行终端设备的轮询。作为示例，轮询可以定期地执行，或者事件触发地进行，例如当有新的用户设备加入或者已有用户设备离开时进行。这样，关键终端设备能够动态地改变，可以保证每个终端设备不会因为分组的波束管理而付出过大的代价。
在确定了关键终端设备之后，可以经由所确定的关键终端设备与基站之间进行波 束扫描来确定基站用于与用户设备组进行通信的组共享波束。特别地，关键终端设备的作用就是代表整个终端设备组找到基站针对该终端设备组的公共的下行发射波束，作为组共享波束。并且在确定了组共享波束之后，关键终端设备通过波束上报机制告知基站该组共享波束。
该组共享波束的确定可采用本领域已知的波束扫描方法来进行，例如前文参照图2B所述的波束对确定方法来进行，或者采用本领域已知的其它方法来进行。
作为示例，在3GPP中，基站基于下行链路波束形成的参考信号选择适合于与关键终端设备的通信的波束。这种下行链路参考信号也称为信道状态信息参考信号(CSI-RS)。首先，基站使用多个波束来发送多个CSI-RS。然后，关键终端设备采用多个接收波束进行接收，并且基于对于该多个CSI-RS的接收结果在用于发送CSI-RS的多个波束中选择适当波束作为该组共享波束。例如，终端设备选择最大的接收信号强度所对应的下行发射波束作为该组共享波束，或者可以选择通信质量最佳的下行发射波束作为该组共享波束。然后，用户设备将指示选择结果的信息上报给基站，该信息例如可包括期望波束的标识信息(例如，波束编号)，从而基站能够使用所选择的发射波束作为组共享的发射波束与该终端设备组进行通信。
最后，需要说明的是，当UE具有上下行的波束对称性时，基站可通过TCI状态(Transmission Configuration Info state，传输配置信息状态)指示给UE的下行发送波束，UE在下行接收时可以使用对应的下行接收波束，在上行发送时可以使用下行对应接收波束所对应的上行发射空间滤波器来发送。从而实现上下行两个方向的基于UE分组波束指示。
在确定了组共享波束之后，基站可以采用该组共享波束与终端设备组进行通信。根据实施例，发射侧电子设备的处理电路进一步配置为：利用所述组共享波束与所述终端设备组中的各个终端设备进行波束扫描，以便确定各个终端设备与发射侧电子设备进行通信的波束。
该波束扫描以及波束确定可采用本领域已知的波束确定方法来进行，例如前文所述的基于CSI-RS的上下行波束对确定方法来进行。特别地，基站采用所确定的组共享波束对于终端设备组中的其它终端设备进行波束扫描，而对于该组共享波束，每个终端设备采用各自的可用的接收波束进行接收，确定其中的通信质量最佳的接收波束作为该终端设备的相应的接收波束。特别地，为了减少接收波束扫描资源的消耗，基站可以把相同的波束扫描资源配置给组内的除关键UE之外的其他UE。作为示例，终 端设备所确定的接收波束可以不上报给基站。
图5示出了根据本公开的实施例的基站与终端设备组之间的基于分组的波束管理结果的示意图，其中通过基站与关键UE之间的下行波束扫描确定了基站的下行发射波束，关键UE将所确定的下行发射波束上报给基站，并且基站可以使用该下行发射波束作为组共享下行发射波束与组中的其它UE进行波束扫描，从而可以确定终端设备组中的各个终端设备的接收波束。
根据本公开的实施例，提出了基于终端设备分组的组共享波束指示方案。在该方案中，可以将所确定的组共享波束的相关信息提供给终端设备组中的各个终端设备，尤其是除关键终端设备之外的其它终端设备。
根据本公开的实施例，此波束指示方案可用于终端设备组中的除关键设备之外的其它设备的接收波束确定，即在采用关键终端设备确定了基站的组共享波束之后，可以向终端设备组传输波束指示信息，从而终端设备可以接收并解码该波束指示信息中所包含的组共享波束信息，由此基于该信息来准备相对应的接收波束。作为一个示例，组共享波束的相关信息的指示可以与在基站与终端设备之间的波束扫描交替地进行。通常，一般波束扫描可以周期性执行，或者非周期性执行，例如由于终端设备接入或者移动而导致分组发生变化而触发进行波束扫描，而波束指示往往是非周期性地，例如分组变化可能导致组共享波束变化，这样就需要将变化的组共享波束告知终端设备。例如，组共享波束的相关信息的指示可以在波束扫描之后执行。应指出，此波束指示方案可以在如前所述的基站与终端设备组中的各个终端设备之间的波束对确定之后来执行。
根据本公开的实施例，组共享波束的相关信息可以由各种设备采用各种适当的方式来提供给终端设备。特别地，组共享波束的相关信息可以由基站或者其它适当设备提供。作为另一示例，该波束指示方案中可以经由适当的信道来传输组共享波束的相关信息。根据本公开的实施例，优选地，组共享波束相关信息是由基站提供给终端设备的，特别地，通过所确定的组共享波束采用适当的信道将组共享波束的相关信息提供给终端设备组中的各个终端设备。当然，组共享波束的相关信息也可通过基站专门针对终端设备的波束来提供给终端设备。例如当终端设备刚刚完成与基站的初始接入，还未为对于该终端设备的发送信道配置组共享波束，则可以使用该终端设备的专属波束来传输组共享波束的相关信息给该终端设备。
根据本公开的实施例，组共享波束的相关信息可包含组共享波束的方向信息，例 如组共享的下行波束方向。在标准中往往使用TCI状态来标识。TCI状态中包含一个下行参考信号(CSI-RS或SSB)或上行参考信号(SRS)。
根据一个实施例，所述处理电路使用组共享(GC)波束经由组共享物理下行控制信道(PDCCH)将组共享波束的相关信息发送给相应的终端设备组。特别地，组共享物理下行控制信道(PDCCH)可指的是对于终端设备组中的各个终端设备都使用一个公共PDCCH，由此来指示组共享波束的相关信息。
图6示出了根据本公开的实施例的基于组共享PDCCH进行组共享波束指示的示意图，其中组共享波束的相关信息被包含在GC-PDCCH所承载的内容中。
这里存在两个组，分别是UE组1和组2，对于两个组分别经由各自对应的组共享波束经由GC-PDCCH提供相应的组共享波束信息，并且每个UE组通过各自对应的组共享波束指示专门的GC-RNTI来标识。作为示例，GC-RNTI可以与组共享波束的相关信息一起传输。
如果组1中的UE被提供了GC-RNTI 1的话，那么它可以解码GC-PDCCH 1中的内容(因为GC-PDCCH 1的CRC是通过GC-RNTI 1进行的加扰操作，解码过程需要使用GC-RNTI 1进行逆向的去加扰操作)，从而得到了组共享的下行波束方向，其往往使用TCI状态来标识。TCI状态中包含一个下行参考信号(CSI-RS或SSB)或上行参考信号(SRS)。UE在解码该所在组的GC-PDCCH后，可以得到该组的共享波束，并且准备对应的接收波束来进行后续信道和信号的接收。另外，在上行方向上，UE可以准备对应各自的上行信道和信号的发射方向。
根据本公开，GC-PDCCH可以采用各种适当的格式。根据一个示例，组共享波束的相关信息，例如TCI状态等，可以添加到现有的PDCCH信令格式中被传输。根据另一实施例，可以引入了全新的GC PDCCH的格式。特别地，本公开的实施例提出了DCI格式2，其被用于将公共TCI状态(波束)告知公共下行链路，其中UE假设对于该UE预期不进行传输。这样，可以利用该DCI格式2，在CRC被GC-RNTI加扰的情况下来传输以下信息：{UE组1，UE组2，…，UE组N，TCI状态1，TCI状态2，…，TCI状态N}，这里的N代表一共有N个UE分组。也就是说，针对每个UE组的组共享波束的相关信息被组成一个公共信息，并且公共信息被经由组共享波束以及GC-PDCCH提供给各个组，以便各个组能够基于该公共消息来获取相应的组共享波束的信息。
根据另一实施例，所述处理电路也可以使用组共享波束经由终端设备组中的各终端设备的专属物理下行控制信道(PDCCH)将组共享波束信息发送给相应的终端设备。 特别地，可以采用组共享波束经由专用于各个终端设备的PDCCH来传输组共享波束信息，这样终端设备接收到信息之后可以直接解码相应PDCCH中的内容以获取组共享波束信息，由此可以准备对应的接收波束来进行后续信道和信号的接收。但是这种情况下，信道开销可能比较大。
根据本公开的实施例，发射侧电子设备的处理电路可以使用组共享波束经由组共享的媒体接入控制-控制元素(MAC CE)的将组共享波束的相关信息发送给相应的终端设备。
特别的，除了上文中考虑的基于GC-PDCCH的组共享波束指示外，我们也可以考虑组共享的MAC CE来进行上下行波束的激活或者去激活操作。值得一提的是，在目前的NR协议中，MAC CE一般是UE专属的信令方式。这里提出使用GC-MAC CE的概念来进行波束管理。基站通过给这个MAC CE分配一个组专属的组别标识，例如LCID(区域设置标识符)或者eLCID来标识，明确指示该MAC-CE所对应的终端设备组。图7示出了根据本公开的实施例的MACCE的格式。
根据本公开的实施例，对于GC-MAC CE，可以有两种传输的方式。图8示出了根据本公开的一个实施例的GC-MAC CE传输的示意图，其中，使用组共享波束经由终端设备专属物理下行共享信道(PDSCH)将组共享波束的相关信息指示给各个终端设备，组共享波束的相关信息被包含在GC-MAC CE中。
如图8所示，在物理层通过UE专属PDSCH来承载GC-MAC CE，在给每一个UE的专属PDSCH中放置相同的MAC CE内容，这样，因为PDSCH的HARQ-ACK的差错控制机制，可以确保每一个UE都可以正确地解码MAC CE，从而准确地获取组共享波束的相关信息，例如组共享波束的方向信息，由此可以准备对应的接收波束来进行后续信道和信号的接收。应指出，这种方式能够实现准确的传输和解码，但是对于物理层无线资源的开销比较大。
图9示出了根据本公开的另一实施例的GC-MAC CE传输的示意图，其中，所述处理电路使用组共享波束经由组共享物理下行共享信道(PDSCH)将组共享波束的相关信息发送给终端设备组中的各个终端设备。
如图9所示，基站可以把GC-MAC CE放到GC-PDSCH中来承载。在终端设备解码GC-PDSCH后，便可以得到GC-MAC CE所携带的组共享波束指示。特别地，类似于GC-PDCCH，终端设备可以根据发送给其的组标识信息，例如RNTI，来解码相应的GC-PDSCH或者公共PDSCH中的相应部分的内容，从而得到GC-MAC CE所携带的内容。 这样做的好处是，GC-PDSCH在物理层仅占用一个PDSCH的资源，从而减少了无线资源的开销。此外，为了传输安全，可以引入HARQ机制来保护差错传输。
UE在解码该所在组的GC-MAC CE后，可以得到该组的共享波束，并且准备对应的接收波束来进行后续信道和信号的接收。另外，在上行方向上，UE可以准备对应各自的上行信道和信号的发射方向。
根据本公开的实施例，组共享波束的相关信息还可以由其它设备提供给终端设备组中的终端设备。特别地，根据本公开的实施例，关键设备可以将所述组共享波束的相关信息告知关键设备所属的终端设备组中的其它终端设备。特别地，在基站与关键设备之间进行波束扫描以确定了上下行波束对时，关键设备已经获知基站所要使用的组共享波束的相关信息，并且将该信息告知终端设备组中的终端设备。
图10示出了根据本公开的实施例的关键终端设备与其它终端设备之间的组共享波束信息传输的示意图。其中，基站通过UE专属的控制信道或者数据信道，将上下行的组共享波束的相关信息告知给关键UE。然后关键UE将组共享波束的相关信息通知给组内的其他UE。关键UE可以采用各种适当方式来进行信息通知。例如，可以通过下行链路(Downlink)或直通链路(Sidelink)的方式。这取决于关键UE所担任的角色和/或所起的作用。如果该UE作为一个非IAB节点的UE，那么它可以把基于MAC CE或者DCI的波束指示信息通过Sidelink的方式，即SCI或PSSCH，通知组内的其他UE。如果该UE作为一个IAB节点，那么它和其他UE的链路可以通过DL的方式。
根据本公开的实施例，关键UE可以通过各种适当的方式来获知组内的其它UE的相关信息，例如其它UE的ID，位置信息等等。作为示例，对于sidelink的UE来说，网络侧可以提供预先的配置，使得UE可以根据自身所在的位置来计算所在的区域标识(ZoneID)，即一个提前规划好的位置区域。关键UE只需要向该区域内广播Sidelink的控制信息，即SCI(Sidelink Control Info.)来传达下行的共波束信息即可。作为另一示例，如果在之前的UE分组阶段基站给关键UE额外地提供了组内的其他UE信息，关键UE可以通过广播SCI来更确切地找到其他UE。
图11示出了根据本公开的实施例的基于分组的波束管理的概念性流程图。特别地，应指出，基站和用户设备之间进行分组、组共享波束确定、各终端设备的接收波束确定等等可以按照上文所示的方式来进行，这里将不再详细描述。
以上描述了根据本公开的实施例的基于终端设备分组的波束管理。其中，将终端 设备进行分组并且确定基站针对终端设备组的一个公共的组共享波束，这样使用公共的组共享波束进行发射侧设备与各个终端设备之间的通信，从而通过多个信道或信号使用相同的波束，可以在满足可靠性的前提下减少不必要的信令开销和时延，这在5G系统运行在毫米波频段时尤其有利。
以上主要描述了基于分组的波束管理，其中基于UE的位置进行UE的分组，以及基站所使用的组共享波束以及UE的相应的接收波束都是基于波束扫描而确定的。
应指出，在本公开的实施例中，可以在无波束扫描、也无波束管理的前提下进行UE的分组，并且组共享波束以及UE的相应接收波束是通过计算而确定的，而没有通过波束扫描。特别地，本实施例尤其适合于UE与波束发射位置距离太远的情况。图12示出了根据本公开的实施例的未采用波束管理的终端设备分组示例，其以卫星通信场景为例进行了描绘。其中无需进行波束管理即可对用户设备的分组，也不再进行基站与用户设备之间的波束管理。
应指出，对于基于卫星的覆盖场景，由于每个UE都可以计算出对于卫星的位置信息，所以波束扫描的过程可以在NTN的场景下省略。因此，也不需要一个关键UE在后期分发组内的共波束信息。如图12(a)所示，网络侧可以通过RRC或者MAC CE信令告知它所服务UE，该卫星所使用的波束的中心角度，即某一个波束的所指向的中心方向。UE通过计算星历图和自身所在的位置来计算UE和卫星之间的夹角。通过对比可以发现UE和卫星的相对位置，哪一个波束更适合UE作为下行的发射波束。因此，在NTN的场景中，常规的波束扫描和上报过程是一个非必要的手段。
另外需要注意的是，由于卫星举例UE的距离较远，一个下行波束可以在地表覆盖非常大的范围，比如半径为60km的区域。因此，UE在一个波束覆盖的区域内自然地形成了一个UE分组，如图12(b)所示。
