Description

用于无线通信的电子设备和方法以及信息处理设备
本申请要求于2022年5月27日提交中国专利局、申请号为202210586272.9、发明名称为“用于无线通信的电子设备和方法以及信息处理设备”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
本申请涉及无线通信技术领域，更具体地，涉及一种利于确定下行波束的用于无线通信的电子设备和方法、信息处理设备以及非暂态计算机可读存储介质。
背景技术
随着技术的发展，人们携带用户设备(user equipment,UE)高速移动并且期望照常进行无线通信的场景越来越多。例如，当人们乘坐高速行进的交通工具(诸如火车的地面车辆或诸如飞机的近地工具)而高速移动时，所携带的UE在沿途基站(地面基站或非地网络(Non-Terrestrial Network，NTN)中的基站)的覆盖范围内高速移动，并且在每个基站(每个小区)的覆盖范围内快速通过不同的下行波束的覆盖区域。
另外，伴随非地网络日益广泛地引用，很多场景下由非地网络中的基站使用或控制相对地面移动的卫星或高速移动的高空平台发出下行波束来向用户设备发送数据。如果没有采用固定波束技术，则上述非地网络中的基站所使用的无线通信波束在地面上的投影将快速移动，其速度可高达数公里每秒。在这种情况下，用户设备将更快速地通过基站的每个下行波束的覆盖区域。
在例如但不限于上述场景的每个波束的波束覆盖时间较短的情况下，为了确保基站始终使用适当的下行波束向UE发送数据，基站侧与UE之间需要持续进行下行波束的波束测量以供基站根据波束测量的结果进行波束切换。

具体实施方式

将按照以下顺序进行描述：
1.概述
2.第一实施例的电子设备的配置示例
3.第二实施例的电子设备的配置示例
4.第三实施例的信息处理设备的配置示例
5.方法实施例
6.应用示例
<1.概述>
如前所述，人们例如乘坐高速行进的交通工具(诸如火车的地面车辆、诸如飞机的近地工具等)高速移动时，所携带的用户设备在沿途基站(地面基站或非地网络中的基站)的覆盖范围内高速移动、甚至在每个基站的不同下行波束的覆盖区域中高速移动。此外，在非地网络中，基站控制下相对地面移动的卫星(低轨卫星或中轨卫星)或高速移动的高空平台所发送的无线通信波束在地面上的投影也快速移动。
在上述用户设备高速移动并且/或者为用户设备提供服务的非地网络中的基站所使用的波束投影快速移动的场景下，用户设备都会快速通过不同下行波束的覆盖区域。
作为示例，图1A和图1B示出了飞机航线穿越卫星波束的示意图。图1A的示例中，非地网络中的基站gNB位于地面，并且与地面上的核心网设备(未示出)通信。基站gNB的卫星小区有两个低轨道(low earth orbit,LEO)卫星卫星作为传输接入点(TRP)覆盖，即，在同一小区使用卫星LEO-1的不同波束即波束1和波束2以及卫星LEO-2的不同波束即波束3和波束4。在飞机通过基站gNB的卫星小区的过程中，其将依次位于波束1至波束4的覆盖区域，并且飞机上的UE将经历3次波束切换。图1B的示例与图1A的区别在于，卫星LEO-1和LEO-2为非透明卫星，即，卫星LEO-1和LEO-2自身用作非地网络中的基站，并且例如直接与地面上的核心网设备(未示出)通信。此时，在飞机通过LEO-1或LEO-2的卫星小区的过程中，其同样将会位于不同波束的覆盖区域，并且飞机上的UE将经历1次波束切换。
图1C示出了卫星波束以及高速交通工具的相关参数的示例，并且图1D示出了使用图1C的参数计算的、未使用波束固定技术的LEO卫星的卫星波束关于飞机的波束覆盖时间的示例。如图1D所示，由于飞机本身的移动加上波束投影的移动，飞机(飞机上的UE)在一个波束里被覆盖的时间变得非常短暂。具体地，在本示例中，如假设波束投影在地面的移动方向与飞机的航行方向完全一致，则在波束投影的直径为50公里的情况下，飞机上被覆盖的时间仅为6.51秒，在投影直径为1000公里的情况下，该时间为130秒；如假设波束投影的移动方向和飞机的航行方向完全相反，则上述两个时间变为6秒和120秒。无论哪种情况下，波束覆盖时间都非常短。
在这种每个波束的波束覆盖时间较短的情况下，为了确保基站始终使用适当的下行波束向UE发送数据，基站侧与UE之间需要持续进行下行波束的波束测量以供基站根据波束测量的结果进行波束切换。
本公开的发明人注意到了诸如上述场景的每个波束的波束覆盖时间较短的情况，并且针对这种情况提出了至少部分地基于用户设备的位置与用于用户设备的当前波束和下一波束的覆盖交叠区域之间的关系而使用适当的下行波束进行数据传输的发明构思，从而利于减少对波束测量的依赖。
接下来，将进一步描述根据本公开的实施例的装置和方法。注意，尽管以上概述和下述具体描述中部分结合了用户设备处于交通工具上和/或由非地网络中的基站为用户设备服务的应用场景作为示例进行了描述，但本公开的实施例不限于上述的应用场景，而是可以适当地应用于任何波束覆盖时间较短的场景，这里不再赘述。
<2.第一实施例的电子设备的配置示例>
(配置示例)
图2是示出根据本公开的第一实施例的电子设备的配置示例的框图。图2所示的电子设备可以用于基站侧，例如可以用于非地网络中的基站侧设备，诸如图1A所示基站gNB的或图1B所示的非透明卫星(具有基站功能)LEO-1或LEO-2。
如图2所示，电子设备100可以包括控制单元110和收发单元120。控制单元110可以控制电子设备100的整体操作，并且收发单元120可以例如在控制单元110的控制下，向电子设备100以外的设备发送信息和/或从电子设备100以外的设备接收信息。此外，尽管图中未示出，但电子设备100还可以包括存储单元。
这里，电子设备100的各个单元都可以包括在处理电路中。需要说明的是，电子设备100既可以包括一个处理电路，也可以包括多个处理电路。进一步，处理电路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。
根据第一实施例，电子设备100的控制单元110可以至少部分地基 于用户设备的位置与用于用户设备的当前波束(当前下行波束)和下一波束(下一下行波束)的覆盖交叠区域之间的关系，将当前波束和下一波束之一或两者确定为使用波束。
图3示出了电子设备100的控制单元110的一个配置示例的框图。如图3所示，控制单元110可以包括波束区域确定单元111和使用波束确定单元112。
波束区域确定单元111可以获得用户设备的位置，并且据此确定用于用户设备的当前波束、下一波束以及覆盖交叠区域。覆盖交叠区域具有边缘，包括用户设备进入该区域的进入侧边缘和离开该区域的离开侧边缘。
波束区域确定单元111可以以各种方式获得用户设备的位置。例如，波束区域确定单元111可以经由电子设备100的收发单元120从用户设备接收其上报(例如实时上报、周期性上报、在预定位置上报、或满足其他预定条件时上报)的位置信息，该位置信息例如包括用户设备的地理位置、(可选的)高度、时间(获得该地理位置/高度的测量时间)等等。
在一个优选示例中，用户设备可以处于具有预定移动路径的交通工具上，并且波束区域确定单元111可以经由电子设备100的收发单元120从另外的设备(诸如设置于核心网或云服务平台的服务器等的信息处理设备)接收关于交通工具的预定移动路径的信息。关于交通工具的预定移动路径的信息例如可以包括指示下述各项的信息：交通工具的标识符(ID)和/或移动路径的编号(航班号/车次等)、移动路径上的地理位置(以及可选的高度)、与移动路径上的地理位置(以及可选的高度)相关联的时间等等。可选地，该信息还可以包括指示移动方向(与移动路径上的地理位置(以及可选的高度)和时间相关联)的信息。
波束区域确定单元111可以基于所获得的相关信息而确定用户设备的当前位置并获得用户设备的预测位置，以用于确定用于用户设备的当前波束和下一波束。例如，在持续获得用户设备上报的位置信息时，控制单元110可以基于当前的位置信息确定用户设备的当前位置，并且可以基于先前和当前的位置信息来估计用户设备的移动路径(包括移动方向)进而获得用户设备的预测位置。在从另外的设备接收关于用户设备 所在交通工具的预定移动路径的信息时，控制单元110可以例如基于该信息中的地理位置(以及可选的高度)与时间的关联而获得用户设备的当前位置和预测位置。
波束区域确定单元111可以基于例如经由上述方式获得的用户设备的当前位置和预测位置，结合其自身控制的各个下行波束(具有基站功能的电子设备100自身发出或电子设备100控制的其他设备例如TRP或透明卫星所发出的下行波束)的覆盖区域，确定用于用户设备的当前波束和下一波束。在本公开中，作为示例，可以将围绕一个波束的覆盖范围的中心位置(该波束的波束质量最高的位置)、以给定的波束质量为边界(即，以给定的波束质量(例如，诸如-140dBm的信号强度)作为等值线)的区域定义为该波束的覆盖区域。
作为示例，波束区域确定单元111可以将覆盖区域包括用户设备的当前位置的波束确定为用于用户设备的当前波束，并将覆盖区域包括用户设备的预测位置、并且在用户设备的移动方向上紧邻当前波束的一下波束确定为用于用户设备的下一波束。注意，这意味着用户设备的预测位置与用户设备的当前位置间隔开一定距离，这可以经由波束区域确定单元111估计预测位置时的适当处理(例如估计移动一定时间和/或距离后的预测位置、不断估计多个预测位置等等)来实现。
波束区域确定单元111可以进一步确定用于用户设备的当前波束和下一波束的覆盖交叠区域，即当前波束的覆盖区域和下一波束的覆盖区域的交叠区域(本文中适当时也简称为交叠区域)。如前所述，在本公开中，将围绕一个波束的覆盖范围的中心、以给定的波束质量为边界的区域作为该波束的覆盖区域，使得这种方式定义的两个相邻波束的覆盖区域的边界(或边缘)将会相交，相交的范围内的区域即为覆盖交叠区域。波束区域确定单元111优选地确定覆盖交叠区域的进入侧边缘，并且可选地还确定确定覆盖交叠区域的离开侧边缘。
可选地，波束区域确定单元111可以利用电子设备100的收发单元120向用户设备提供关于当前波束的信息、关于下一波束的信息、关于覆盖交叠区域的边缘的信息中的一项或更多项。关于当前/下一波束的信息包括但不限于该波束的波束指示信息，关于覆盖交叠区域的边缘的信息包括但不限于该边缘的位置信息。可选地，关于交通工具的预定移动路径的信息波束区域确定单元111可以在适当时利用电子设备100的收发 单元120将转发给交通工具上的用户设备(稍后描述)。
使用波束确定单元112可以根据一个或多个预定规则，至少部分地基于波束区域确定单元111所获得的用户设备的位置与波束区域确定单元111所确定的覆盖交叠区域、特别是与覆盖交叠区域的边缘之间的关系，将当前波束和下一波束之一或两者确定为使用波束。
在一个示例中，使用波束确定单元112进行使用波束确定的预定规则可以包括：基于用户设备的位置与覆盖交叠区域的边缘之间的关系而确定是否进行波束测量，并基于上述关系以及可选地结合波束测量的结果而确定使用波束。在另一个示例中，使用波束确定单元112进行使用波束确定的预定规则可以包括：仅基于用户设备的位置与覆盖交叠区域的边缘之间的关系，在不进行波束测量的情况下确定使用波束。
在控制单元110例如利用诸如图3所示的使用波束确定单元112基于预定规则将当前波束和下一波束之一或两者确定为使用波束后，收发单元120可以利用该使用波束向用户设备发送数据。可选地，收到单元120可以预先向用户设备提供与控制单元110(使用波束确定单元112)进行使用波束确定的预定规则有关的信息(稍后描述)。
以上描述了第一实施例的电子设备100的配置示例。利用本实施例的电子设备100，可以减少对波束测量的依赖。例如，可以减少所进行的波束测量，从而利于降低与波束测量相关的能耗和信令交互。
接下来，将适当结合示例场景，进一步描述电子设备100利用各个单元特别是其控制单元110进行的示例处理。

在本示例中，用户设备处于具有预定移动路径的交通工具上，并且电子设备100可以利用控制单元110(例如波束区域确定单元111)经由收发单元120从另外的设备(诸如设置于核心网或云服务平台的服务器等的信息处理设备)接收关于交通工具的预定移动路径的信息，并且可以至少部分地基于关于预定移动路径的信息，确定用户设备的位置、当前波束和下一波束。电子设备100还可以利用控制单元110(例如波束区域确定单元111)基于所确定的当前波束和下一波束的覆盖区域而进一步确定覆盖交叠区域(包括覆盖交叠区域的边缘)。
图4示意性地示出了飞机上的用户设备UE通过电子设备100所控制的当前波束和下一波束的覆盖区域的示例。电子设备100例如可以从另外的设备获得关于图4所示的飞机的航线R的信息，并且可以利用控制单元110(波束区域确定单元111)基于该信息中的地理位置和高度与时间的关联而确定各个时间处的用户设备的位置，并且据此结合自身控制的下行波束的覆盖区域而获得各个时间处的用于用户设备的波束，包括如图4所示的当前波束BC和下一波束BN。
电子设备100可以进一步利用控制单元110(波束区域确定单元111)，根据当前波束BC和下一波束BN的边界在点I和I’相交，确定当前波束BC在点I和I’之间的边界为进入侧边缘L1、下一波束BN在点I和I’之间的边界为离开侧边缘L2，继而确定进入侧边缘L1和离开侧边缘L2之间的覆盖交叠区域。可选地，电子设备100可以进一步利用控制单元110(波束区域确定单元111)，根据交通工具的预定移动路径(诸如图4所示的航线)和覆盖交叠区域边缘(诸如图4所示的进入侧边缘L1和离开侧边缘L2)的位置而确定用户设备到达边缘的预测位置(诸如图4所示的预测进入位置P1和预测离开位置P2)。
电子设备100可以例如经由收发单元120而向用户设备提供关于当前波束的信息、关于下一波束的信息以及关于覆盖交叠区域(覆盖交叠区域的边缘)的信息中的一项或更多项。作为示例，关于覆盖交叠区域的边缘的信息可以指示下述中的至少一者：覆盖交叠区域的边缘的位置(诸如图4所示的边缘L1和/或L2的位置)；以及根据预定移动路径和边缘的位置而确定的用户设备到达边缘的预测位置(诸如图4所示的预测位置P1和/或P2)。可选地，在基于关于交通工具的预定移动路径的信息进行了相关确定的情况下，电子设备100还可以经由收发单元120向用户设备提供关于交通工具的预定移动路径的信息以供后者参考。
图5示意性地示出了具有电子设备100的功能的基站侧设备(gNB)、用户设备UE、用于提供交通工具的移动路径信息的诸如服务器的信息处理设备(Server)之间与上述波束区域确定示例处理相关的示例信息交互。
如图5所示，gNB(用于gNB的电子设备100)例如可以预先(或持续获得)关于交通工具的移动路径的信息，并且在用户设备UE在起飞后或飞行中接入gNB之后，可选地获得UE在接入gNB后上报(或定时上报或周期性上报)的位置信息。gNB(用于gNB的电子设备100)可 以基于关于交通工具的移动路径的信息，可选地结合UE上报的位置信息，按照此前所述的方式确定UE的位置、当前波束和下一波束，并进一步确定覆盖交叠区域的边缘，并向UE提供关于当前波束的信息、关于下一波束的信息和关于覆盖交叠区域的边缘的信息。可选地，尽管图中未示出，gNB还可以连同这些信息一起或另外地向UE提供关于交通工具的预定移动路径的信息。gNB还可以连同这些信息一起或另外地向UE提供关于基站侧后续进行使用波束确定的一个或多个预定规则的信息(稍后描述)。
在图5所示的示例中，用于gNB的电子设备100例如可以通过比较关于交通工具的移动路径的信息与UE上报的位置信息而判定UE处于该交通工具上。在UE接入gNB之后，gNB与UE之间可以以各种方式进行位置信息的上报、当前/下一波束及覆盖交叠区域边缘的确定、当前/下一波束及覆盖交叠区域边缘等相关信息的通知的过程，例如周期性地进行、在UE经过边缘位置后进行、以及发生波束切换后进行，等等。
在一个示例中，电子设备100可以是非地网络基站(例如图1A所示的gNB或图1B所示的LEO-1或LEO-2)，并且可以利用控制单元110(波束区域确定单元111)在关于交通工具的预定移动路径的信息的基础上，进一步基于非地网络基站控制的发送下行波束的卫星的星历图(以及可选的卫星的地理位置)，确定用户设备的当前波束和下一波束。例如，电子设备100可以利用控制单元110(波束区域确定单元111)根据卫星的星历图确定每个波束的覆盖区域的移动轨迹，并根据每个波束的覆盖区域的移动轨迹、基于关于交通工具的预定移动路径的信息中地理位置/高度与时间的关联而确定的各个时间处的用户设备的位置，获得各个时间处的用于用户设备的波束，例如如图4所示的当前波束BC和下一波束BN。在这种情况下，在图5的示例中，用于gNB的电子设备100例如可以预先获得卫星的星历图和/或地理位置的信息。
此外，尽管图5的示例中未示出，但可选地，电子设备100可以利用控制单元110(波束区域确定单元111)，在用户设备(UE)接入非地网络基站(gNB)后，启动为卫星的星历图和/或地理位置(以及可选的卫星天线模式)更新而设置的定时器；在定时器期满之后，确定非地网络基站控制的卫星的星历图和/或地理位置(以及可选的卫星天线模式)是否更新；并且在发生更新的情况下，基于更新的星历图和/或地理位置 (以及可选的更新的卫星天线模式)进行用户设备的当前波束和下一波束的确定(以及可选地进一步进行覆盖交叠区域的边缘的确定)。可选地，电子设备100还可以向用户设备提供更新后确定的各项信息。上述定时器可以是周期的或非周期的。利用该定时器，可以确保当前波束、下一波束(以及可选地覆盖交叠区域的边缘)的确定的准确性。
从电子设备100获得的关于当前波束的信息、关于下一波束的信息和关于覆盖交叠区域的边缘的信息(以及可选的关于交通工具的预定移动路径的信息、关于使用波束确定的预定规则的信息)可以使得用户设备自身监控其是否处于覆盖交叠区域(例如是否到达覆盖交叠区域的边缘)以及知晓其所处于的波束区域(以及可能知晓其所使用的使用波束，稍后描述)。
在交通工具的实际运行中，例如飞机、客车、轮船甚至火车等，都可能出现实际路径与预定路径偏离的情况。图6示意性地示出了飞机上的UE通过当前波束和下一波束的覆盖区域的示例，其中，飞机的实际航线R’偏离了预定航线R。在这种情况下，用户设备到达覆盖交叠区域的边缘(L1、L2)的实际位置(P1’、P2’)可能与电子设备100提供的关于覆盖交叠区域的边缘的信息指示的、用户设备到达边缘的预测位置(P1、P2)不一致。
鉴于上述情况，在用户设备从电子设备100获得的关于覆盖交叠区域的边缘的信息指示用户设备到达所述边缘的预测位置的情况下，用户设备可以在用户设备到达所述边缘的实际位置与所述预测位置不一致时，向电子设备发送指示所述不一致的偏差报告。相应地，电子设备100可以经由收发单元120接收用户设备在用户设备到达所述边缘的实际位置与所述预测位置不一致时发送的指示所述不一致的偏差报告。可选地，电子设备100可以利用控制单元110(例如波束区域确定单元110)参考所述偏差报告，进行(后续)用户设备的位置、当前波束和下一波束的确定。
图7示意性地示出了具有电子设备100的功能的基站侧设备gNB和用户设备UE之间与上述偏差报告相关的部分示例信息交互。如图7所示，例如UE在以不同于预测位置(P1、P2)的实际位置(P1’、P2’)飞过覆盖交叠区域的边缘(L1、L2)后，生成并向gNB(具有电子设备100的功能)发送表示这种不一致的偏差报告，其例如可以具有偏差值(P1’-P1, P2’-P2)的形式。gNB可以参考该偏差报告而校正UE的位置以及UE所在交通工具的移动路径。例如，gNB可以将关于交通工具的预定移动路径的信息所指示的UE当前位置/下一位置/全部后续位置加上偏差值，例如(P1’-P1)和/或(P2’-P2)或其平均，而实现上述校正。gNB可以基于校正后的移动路径，按照此前描述的方式确定后续的UE位置、当前波束和下一波束，并且可选地确定后续的覆盖交叠区域的边缘。尽管图7中未示出，但gNB可以向UE提供经过校正处理以上述方式确定的关于当前波束的信息、关于下一波束的信息和关于覆盖交叠区域的边缘的信息。图7的示例处理可以在飞机每次飞过覆盖交叠区域的边缘时进行，以便持续基于最新偏差进行校正。
(使用波束确定的示例处理)
在本示例中，考虑电子设备100例如利用控制单元110(使用波束确定单元112)根据使用波束确定的一个或多个预定规则，至少部分地基于用户设备的位置与(例如利用波束区域确定单元111得到的)覆盖交叠区域的边缘之间的关系，将当前波束和下一波束之一或两者确定为使用波束的相关示例处理。
作为示例，电子设备100可以例如经由控制单元110(使用波束确定单元112)，利用用户设备上报的位置信息和/或关于交通工具的预定移动路径的信息，确定用户设备的位置与覆盖交叠区域的边缘之间的关系，例如用户设备的位置是否靠近(到达)或远离覆盖交叠区域的边缘。
例如，根据使用波束确定的第一预定规则，电子设备100可以在用户设备的位置远离覆盖交叠区域的边缘时仅使用用于用户设备的当前波束作为使用波束。具体地，电子设备100可以在用户设备的位置距当前波束的覆盖区域的中心的预定距离内(该距离可以适当设置，并且例如与波束的覆盖区域的半径成比例，等等)时，确定用户设备的位置远离覆盖交叠区域的边缘(远离覆盖交叠区域)，并且据此在不与用户设备进行任何波束测量的情况下直接确定仅使用用于用户设备的当前波束作为使用波束。电子设备100可以利用收发单元120预先向用户设备发送了关于上述第一预定规则的信息(例如与图5中关于当前波束的信息、关于下一波束的信息和关于覆盖交叠区域的边缘的信息一起提供)，使得用户设备可以在位置远离覆盖交叠区域时了解基站侧实际使用的下行波束即为此前所接收的关于当前波束的信息(例如参见图5)所指示的“当前 波束”。
此外，电子设备100可以在用户设备的位置在覆盖交叠区域附近时根据另外的预定规则(例如但不限于稍后描述的第二、第三或第四预定规则)确定使用波束。
作为示例，电子设备100可以在用户设备的位置距覆盖区域区域的边缘上的预测位置(根据交通工具的预定移动路径和覆盖交叠区域边缘的位置而确定的用户设备到达边缘的预测位置，诸如图4所示的预测进入位置P1和预测离开位置P2)的中心的预定距离内(该距离可以适当设置，并且例如可与波束的覆盖区域的半径成比例，等等)时，确定用户设备的位置到达覆盖交叠区域的边缘(在覆盖交叠区域附近)。可选地，在电子设备100向用户设备提供了关于覆盖交叠区域的边缘的信息并且该信息指示了用户设备到达边缘的预测位置的情况下，用户设备可以在需要时按照类似准则判断自身是否到达覆盖交叠区域的边缘(在覆盖交叠区域附近)，并且在到达相应的进入侧边缘和/或离开侧边缘时向电子设备100发送边缘到达报告，使得电子设备100知晓用户设备到达相应边缘(在覆盖交叠区域附近)。
针对用户设备的位置在覆盖交叠区域附近的情况(例如靠近或进入覆盖交叠区域、在覆盖交叠区域内、离开覆盖交叠区域等等)，电子设备可以利用控制单元110(使用波束确定单元112)根据使用波束确定的一个或多个预定规则(例如但不限于稍后描述的第二、第三或第四预定规则)确定使用波束。
覆盖交叠区域附近部分地基于波束测量的使用波束确定的示例
在本示例中，电子设备100可以基于用户设备的位置到达覆盖交叠区域的边缘(例如进入侧边缘)而确定进行波束测量，并结合波束测量的结果而确定使用波束。
更具体地，电子设备100可以在用户设备的位置到达覆盖交叠区域的进入侧边缘前不与用户设备进行波束测量，并且利用控制单元110(使用波束确定单元112)，在用户设备的位置到达进入侧边缘后与用户设备进行下一波束的波束测量，利用收发单元120从用户设备接收波束测量的结果，并利用控制单元110(使用波束确定单元112)根据该结果确定使用当前波束和下一波束之一或两者，利用收发单元120以所确定的使 用波束向用户设备发送数据。
图8和图9分别示意性地示出了gNB与UE之间与上述使用波束确定的示例处理相关的两个示例信息交互，其中分别采用了使用波束确定的第二预定规则和第三预定规则，并且gNB预先向UE发送了关于相应的预定规则的信息(例如与图5中关于当前波束的信息、关于下一波束的信息和关于覆盖交叠区域的边缘的信息一起提供)。
如图8和图9所示，具有电子设备100的功能的gNB可以基于用户设备UE上报的位置信息确定用户设备的位置到达覆盖交叠区域的进入侧边缘(例如确定UE靠近图4所示的预测进入位置P1)，或者基于用户设备上报的边缘到达报告而知晓用户设备的位置到达进入侧边缘，此后与UE进行下一波束的波束测量。该测量例如可以通过gNB(例如在生成并向UE发送可选的测量通知以指示下一波束的时频资源和波束方向等后)控制持续发送(例如gNB控制的卫星等持续发送)例如图4所示的下一波束BN、UE持续测量该下一波束的波束质量(UE例如基于测量通知所指示的时频资源和波束方向等接收并测量该下行波束)而进行，这里不再赘述。
根据使用波束确定的第二预定规则，基站侧在用户设备的位置到达覆盖交叠区域的进入侧边缘后下一波束的波束测量的结果高于第一阈值持续第一时段的情况下确定使用当前波束和下一波束两者。
如图8所示，在测量下一波束(例如图4所示的下一波束BN)的波束测量的过程中，用户设备UE可以在该下一波束的波束测量的结果高于第一阈值持续第一时段的情况下，生成并向gNB发送第一测量结果报告。换言之，具有电子设备100的功能的gNB可以利用收发单元120接收用户设备UE在下一波束(例如图4所示的下一波束BN)的波束测量的结果高于第一阈值持续第一时段的情况下发送的第一测量结果报告。进一步地，具有电子设备100的功能的gNB可以利用控制单元110(使用波束确定单元112)根据第一测量结果报告确定使用当前波束和下一波束两者，利用收发单元120使用当前波束和下一波束两者向用户设备UE发送数据。相应地，UE可以从gNB接收使用当前波束和下一波束两者发送的数据。
以图8所示的方式，在UE到达覆盖交叠区域的进入侧边缘后、下一 波束的波束质量持续较佳一段时间时，认为UE进入覆盖交叠区域中并且下一波束的波束质量可接受，从而gNB使用两个波束进行下行数据传输，这有利于改进覆盖交叠区域中的传输质量(例如，仅使用当前波束或仅使用下一波束都可能导致传输质量不佳)。替选地，如果UE进入覆盖交叠区域但下一波束的波束质量没能持续表现良好，则gNB仅继续使用当前波束进行下行数据传输。上述过程避免了对当前波束的持续测量。
此外，根据使用波束确定的第三预定规则，基站侧在用户设备的位置到达覆盖交叠区域的进入侧边缘后下一波束的波束测量的结果高于第二阈值持续第二时段的情况下确定仅使用下一波束。
如图9所示，在测量下一波束(例如图4所示的下一波束BN)的波束测量的过程中，用户设备UE还可以在该下一波束的波束测量的结果高于第二阈值持续第二时段的情况下，向gNB发送第二测量结果报告。换言之，具有电子设备100的功能的gNB可以利用收发单元120接收用户设备UE在下一波束(例如图4所示的下一波束BN)的波束测量的结果高于第二阈值持续第二时段的情况下发送的第二测量结果报告。进一步地，具有电子设备100的功能的gNB可以利用控制单元110(使用波束确定单元112)根据第二测量结果报告确定仅使用下一波束，可以利用收发单元120仅使用下一波束向用户设备UE发送数据。相应地，UE可以从gNB接收仅使用下一波束发送的数据。优选地，第二阈值高于第一阈值以及/或者第二时段长于第一时段。图9所示的示例交互流程可以与图8所示的示例交互流程并行地进行，或者在图8所示的示例交互流程结束之后进行(即可以同时或先后应用第二、第三预定规则)，本公开对此不进行限制。
以图9所示的方式，在UE到达覆盖交叠区域的进入侧边缘后、下一波束的波束质量持续较佳较长时段或持续优异一段时间时，认为UE已经通过覆盖交叠区域并且进入下一波束的覆盖区域，从而gNB仅使用下一波束进行下行数据传输。替选地，如果UE进入覆盖交叠区域但下一波束的波束质量没能持续表现良好较长时段或持续优异一段时间，则gNB仅继续使用当前使用的波束(当前波束，或者当前波束和下一波束两者)进行下行数据传输。上述过程避免了对当前波束的持续测量。
覆盖交叠区域附近避免波束测量的使用波束确定的示例
在本示例中，电子设备100可以基于用户设备的位置到达覆盖交叠区域的边缘而在不进行波束测量的情况下直接确定使用波束。
更具体地，根据使用波束确定的第四预定规则，基站侧在用户设备的位置到达覆盖交叠区域的进入侧边缘时确定使用当前波束和下一波束两者，并且在用户设备的位置到达离开侧边缘时确定使用下一波束。电子设备100可以在用户设备的位置到达覆盖交叠区域的进入侧边缘前不与用户设备进行波束测量，并且利用控制单元110(使用波束确定单元112)在用户设备的位置到达进入侧边缘时确定使用当前波束和下一波束两者，进而利用收发单元120以当前波束和下一波束两者向用户设备发送数据，利用控制单元110(使用波束确定单元112)在用户设备的位置到达离开侧边缘时确定使用下一波束，进而利用收发单元120仅使用下一波束向用户设备发送数据。
图10示意性地示出了gNB与UE之间与上述使用波束确定的示例处理相关的示例信息交互，其中采用了使用波束确定的第四预定规则并且gNB预先向UE发送了关于该预定规则的信息(例如与图5中关于当前波束的信息、关于下一波束的信息和关于覆盖交叠区域的边缘的信息一起提供)。
如图10所示，具有电子设备100的功能的gNB可以基于用户设备UE上报的位置信息确定用户设备的位置到达覆盖交叠区域的进入侧边缘或离开侧边缘(例如确定UE靠近图4所示的预测进入位置P1或预测离开位置P2)，或者基于用户设备上报的边缘到达报告而知晓用户设备的位置到达进入侧边缘或离开侧边缘。根据使用波束确定的第四预定规则，gNB可以不进行任何波束测量，而仅基于用户设备的位置到达相应的边缘而确定使用相应波束向用户设备发送数据。
以图10所示的方式，在UE到达覆盖交叠区域的进入侧边缘后、尚未到达离开侧边缘前，gNB使用当前波束和下一波束两个波束进行下行数据传输。这有利于改进覆盖交叠区域中的传输质量(例如，仅使用当前波束或仅使用下一波束都可能导致传输质量不佳)。此外，在UE到达覆盖交叠区域的离开侧边缘后，认为UE已经通过覆盖交叠区域并且进入下一波束的覆盖区域，从而gNB仅使用下一波束两者进行下行数据传输。以此方式，本示例中全程避免了波束测量而实现了仅基于地理位置的波束切换，从而降低了与波束测量相关的能耗和信令交互。
在以上图8、图9或图10的示例中，具有电子设备100的功能的gNB利用收发单元120预先向用户设备UE发送了关于第二、第三或第四预定规则的信息(例如与图5中关于当前波束的信息、关于下一波束的信息和关于覆盖交叠区域的边缘的信息一起提供)，这使得UE可以根据相应规则在无需基站实时通知的情况下了解基站侧实际使用的下行波束。
例如，在图8或图9的示例中，UE可以根据第二或第三预定规则，在生成相应的第一或第二测量结果报告的同时即了解基站侧实际使用的下行波束即为此前所接收的关于当前波束的信息和关于下一波束的信息所指示的“当前波束”和“下一波束”或者此前所接收的关于下一波束的信息所指示的“下一波束”。在图10的示例中，UE可以根据第四预定规则而根据UE的位置了解实际使用的波束。
此外，替选地或可选地，在以上图8、图9或图10的示例中，尽管图中未示出，具有电子设备100的功能的gNB可以在使用改变了的波束进行数据传输之前再次利用收发单元120向UE发送针对实际的使用波束的波束指示以使UE知晓实际的使用波束。
此外，在以上图9或图10(第三或第四预定规则)的示例中，在具有电子设备100的功能的gNB确定仅使用下一波束进行下行数据传输的情况下，其实认为UE已进入下一波束的覆盖区域并且实现了波束切换，因此可以将下一波束BN设置为新的当前波束BC。此时，可选地，电子设备100可以利用其控制单元110(波束区域确定单元111)按照与此前描述的方式大致类似的方式再次进行确定UE的位置、当前波束和下一波束的处理以及确定覆盖交叠区域的边缘的处理。可选地，此时UE的位置可以基于UE上报的位置信息和/或UE所在的交通工具的预定移动路径的信息而按照此前描述的方式类似地确定、或者直接确定为离开侧边缘上的预测位置(例如图4所示的预测离开位置P2)，UE的当前波束可以直接基于波束切换而确定(此前的下一波束BN设置为新的当前波束BC)，下一波束以及覆盖交叠区域的边缘可以按照此前描述的方式类似地确定。尽管图9或图10中未示出，但可选地，电子设备100可以利用其收发单元120将上述确定的各项信息提供给用户设备UE以供后续使用，这里不再赘述。
以上描述了根据本公开的第一实施例的(基站侧的)电子设备100，其使得可以利用用户设备的位置与波束交叠区域之间的关系而使用适当 的下行波束进行数据传输，这有利于减少对波束测量的依赖。
在以上根据本公开的第一实施例的基站侧的电子设备100的描述过程中，除了基站侧的电子设备100之外，同样描述了由该电子设备100服务的用户设备UE、以及为电子设备100提供交通工具的预定路径信息的另外的设备例如设置于核心网或云服务平台的服务器等的信息处理设备。换言之，根据本公开的实施例，发明人除了提出了基站侧的电子设备之外，还提出了用户侧的电子设备以及信息处理设备。以下将在根据本公开的第一实施例的基站侧的电子设备的描述的基础上，给出根据本公开的第二实施例的用户侧的电子设备以及根据本公开的第三实施例的信息处理设备的描述，并且省略其不必要的细节。
<3.第二实施例的电子设备的配置示例>
图11是示出根据本公开的第二实施例的用户侧的电子设备的配置示例的框图。该电子设备可以用于在第一实施例的基站侧设备部分所描述的由该基站侧设备服务的用户设备UE(例如图1A或图1B中的飞机上的UE)。
如图11所示，电子设备200可以包括收发单元210以及可选的位置信息生成单元220和测量单元230。收发单元210例如向电子设备200以外的设备发送信息和/或从电子设备200以外的设备接收信息。此外，尽管图中未示出，但电子设备200还可以包括用于控制其整体操作/一般操作的控制单元和用于存储功能的存储单元。
这里，电子设备200的各个单元都可以包括在处理电路中。需要说明的是，电子设备200既可以包括一个处理电路，也可以包括多个处理电路。进一步，处理电路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。
根据本实施例，收发单元210可以从网络侧设备接收数据，所述数据是至少部分地基于用户设备的位置与用于用户设备的当前波束和下一波束的覆盖交叠区域之间的关系而使用当前波束和下一波束之一或两者发送的。网络侧设备例如可以是基站侧的设备(例如图1A所示基站gNB的或图1B所示的非透明卫星(具有基站功能)LEO-1或LEO-2)。覆盖交叠区域可以具有边缘，包括用户设备进入该区域的进入侧边缘和离开 该区域的离开侧边缘。此外，可选地，收发单元210还可以从网络侧设备接收其进行使用波束确定的预定规则，例如但不限于此前在第一实施例中描述的第一至第四预定规则中的一个或更多个。
可选的位置信息生成单元220可以例如利用全球定位系统(Global Positioning System,GPS)模块等各种定位功能持续监控用户设备的位置，并且生成用户设备的位置信息，该位置信息例如包括用户设备的地理位置、(可选的)高度、时间(获得该地理位置/高度的测量时间)等等。位置信息生成单元220可以利用收发单元210向网络侧设备上报(例如实时上报、周期性上报、在预定位置上报、或满足其他预定条件时上报)所生成的位置信息，以供网络侧设备确定用户设备的位置。
在一个优选示例中，用户设备可以处于具有预定移动路径的交通工具上。此时，网络侧设备例如可以预先以各种适当方式获得关于交通工具的预定移动路径的信息，并且可以至少部分地基于至少部分地基于关于预定移动路径的信息，确定用户设备的位置。
如前所述，网络侧设备(基站侧设备)可以基于用户设备的位置(根据用户设备上报的位置信息或关于交通工具的预定移动路径的信息而确定的用户设备的位置)以及其所控制的下行波束的覆盖范围等，确定用于用户设备的当前波束和下一波束(例如图4所示的当前波束BC和下一波束BN)，并且进一步确定两者的覆盖交叠区域(覆盖交叠区域的边缘，例如图4所示的进入侧边缘L1和/或离开侧边缘L2)。可选地，网络侧设备可以根据交通工具的预定移动路径(诸如图4所示的航线R)和覆盖交叠区域边缘(诸如图4所示的L1和L2)的位置而确定用户设备到达边缘的预测位置(诸如图4所示的P1和P2)。
电子设备200可以例如经由收发单元210而从网络侧设备获得关于当前波束的信息、关于下一波束的信息以及关于覆盖交叠区域(覆盖交叠区域的边缘)的信息中的一项或更多项。作为示例，关于覆盖交叠区域的边缘的信息可以指示下述中的至少一者：覆盖交叠区域的边缘的位置(诸如图4所示的边缘L1和/或L2的位置)；以及根据预定移动路径和边缘的位置而确定的用户设备到达边缘的预测位置(诸如图4所示的预测位置P1和/或P2)。
此外，可选地，在网络侧设备获得了关于用户设备所在的交通工具 的预定移动路径的信息并基于该信息进行了当前波束等相关确定的情况下，电子设备200还可以利用收发单元210从网络侧设备接收其发送的关于交通工具的预定移动路径的信息。
作为示例，电子设备200向网络侧设备上报位置信息以及从网络侧接收关于当前波束的信息、关于下一波束的信息以及关于覆盖交叠区域(覆盖交叠区域的边缘)的信息(以及可选的关于交通工具的预定移动路径的信息、关于使用波束确定的预定规则的信息)等的过程可以经由此前参照图5描述的示例信息交互流程实现。换言之，用于用户设备的电子设备200可以利用其收发单元210和位置信息生成单元220等实现参照图5描述的示例交互中的UE的全部功能或处理，这里不再赘述。
从网络侧设备获得的关于当前波束的信息、关于下一波束的信息和关于覆盖交叠区域的边缘的信息(以及可选的关于交通工具的预定移动路径的信息、关于使用波束确定的预定规则的信息)可以使得电子设备200例如利用其位置信息生成单元220监控其自身是否处于覆盖交叠区域(例如是否到达覆盖交叠区域的边缘)，并且可以使得电子设备200知晓其所处于的波束区域(以及可能知晓其所使用的使用波束，稍后描述)。
在交通工具的实际运行中，可能出现实际路径与预定路径偏离的情况，诸如图6中飞机的实际航线R’偏离了预定航线R的示例。在这种情况下，如图6所示，用户设备到达覆盖交叠区域的边缘(L1、L2)的实际位置(P1’、P2’)可能与从网络侧设备获得的关于覆盖交叠区域的边缘的信息指示的、用户设备到达边缘的预测位置(P1、P2)不一致。
鉴于这种情况，电子设备200的位置信息生成单元220可以被配置为在从网络侧设备获得的关于覆盖交叠区域的边缘的信息指示用户设备到达所述边缘的预测位置的情况下，在用户设备到达所述边缘的实际位置与所述预测位置不一致时，生成并利用收发单元210向网络侧设备发送指示所述不一致的偏差报告。作为示例，该偏差报告可以指示实际位置(P1’、P2’)与预测位置(P1、P2)之间的偏差值，例如，(P1’-P1,P2’-P2)。网络侧设备可以参考该偏差报告而校正用户设备的位置以及用户设备所在交通工具的移动路径，并将校正后的位置和/或路径用于后续处理。
作为示例，电子设备200生成并向网络侧设备发送偏差报告的过程可以经由此前参照图7描述的示例信息交互流程实现。换言之，用于用 户设备的电子设备200可以利用其收发单元210和位置信息生成单元220等实现参照图7描述的示例交互中的UE的全部功能或处理，这里不再赘述。
如前所述，网络侧设备(基站侧设备)可以根据使用波束确定的预定规则，至少部分地基于用户设备的位置与覆盖交叠区域(覆盖交叠区域的边缘)之间的关系确定使用波束，并且电子设备200可以经由收发单元210预先从网络侧设备接收上述预定规则(例如与图5中关于当前波束的信息、关于下一波束的信息和关于覆盖交叠区域的边缘的信息一起接收)，例如但不限于此前在第一实施例中描述的第一至第四预定规则中的一个或更多个。电子设备200可以基于其所接收到的相应的使用波束确定规则而进行适当处理。
例如，针对用户设备的位置远离覆盖交叠区域的情形，根据使用波束确定的第一预定规则(在用户设备的位置远离覆盖交叠区域的边缘时仅使用用于用户设备的当前波束作为使用波束)，网络侧设备可以在确定用户设备的位置远离覆盖交叠区域的边缘(远离覆盖交叠区域)时，在不与用户设备进行任何波束测量的情况下仅使用用于用户设备的当前波束作为使用波束。
相应地，在接收到第一预定规则(例如与图5中关于当前波束的信息、关于下一波束的信息和关于覆盖交叠区域的边缘的信息一起接收)的情况下，用户侧的电子设备200例如可以经由位置信息生成单元220监控自身位置，并在确定用户设备的位置远离覆盖交叠区域的边缘(远离覆盖交叠区域)时知晓实际使用的下行波束为从网络侧设备接收的关于当前波束的信息(例如参见图5)所指示的“当前波束”。例如，位置信息生成单元220可以在用户设备的位置距当前波束的覆盖区域的中心的预定距离(该距离例如为当前波束的覆盖区域的半径的一半或更小)内时，确定用户设备的位置远离覆盖交叠区域的边缘(远离覆盖交叠区域)，并且据此知晓实际的使用波束为关于当前波束的信息所指示的“当前波束”。
此外，针对用户设备的位置在覆盖交叠区域附近的情形，例如根据使用波束确定的第二或第三预定规则，网络侧设备可以基于用户设备的位置到达覆盖交叠区域的边缘(例如进入侧边缘)而确定进行波束测量，并结合波束测量的结果而确定使用波束；例如根据使用波束确定的第四 预定规则，网络侧设备可以仅基于用户设备的位置到达覆盖交叠区域的边缘，在不进行波束测量的情况下确定使用波束。
相应地，接收到第二、第三或第四预定规则的用户侧的电子设备200例如可以经由位置信息生成单元220监控用户设备的位置，并确定用户设备的位置是否到达覆盖交叠区域的边缘，进而根据相应的预定规则(以及可选的网络侧的进一步指示)利用相应单元进行相应处理。
作为示例，可选地，在网络侧设备向用户设备提供了关于覆盖交叠区域的边缘的信息并且该信息指示了用户设备到达边缘的预测位置的情况下，例如接收到第二、第三或第四预定规则的电子设备200的位置信息生成单元220可以被配置为：判断用户设备是否到达覆盖交叠区域的相应边缘(在覆盖交叠区域附近)，并且在到达相应的进入侧边缘和/或离开侧边缘时生成并利用收发单元210向网络侧设备发送边缘到达报告，使得网络侧设备知晓用户设备到达相应边缘(在覆盖交叠区域附近)。例如，位置信息生成单元220可以在用户设备的位置距覆盖区域的边缘上的预测位置(诸如图4所示的位置P1或P2)的中心的预定距离(该距离例如为当前波束的覆盖区域的半径的四分之一或更小)内时，确定用户设备的位置到达覆盖交叠区域的边缘(在覆盖交叠区域附近)。
此外，在一个示例中，在网络侧设备使用第二或第三预定规则并且基于用户设备的位置到达覆盖交叠区域的边缘(例如进入侧边缘)而确定进行波束测量的情况下，例如接收到第二或第三预定规则的电子设备200的可选的测量单元230可以基于位置信息生成单元220确定用户设备的位置到达覆盖交叠区域的边缘和/或基于从网络侧设备接收到的测量通知，进行相应的下行波束(即，此前从网络侧接收的如图5所示的关于下一波束的信息所指示的“下一波束”)的测量。测量单元230还可以基于波束测量的结果，在适当时生成波束测量报告并利用收发单元210向网络侧设备发送波束测量被告，以供网络侧设备进行使用波束的确定。
更具体地，在本示例中，接收到使用波束确定的第二或第三预定规则的电子设备200的测量单元230可以被配置为：在用户设备的位置到达进入侧边缘前不进行波束测量；以及在用户设备的位置到达进入侧边缘后与网络侧设备进行下一波束的波束测量，并且生成并利用收发单元210向网络侧设备报告波束测量的结果，以供网络侧设备根据该结果使用当前波束和下一波束之一或两者向用户设备发送数据。作为示例，该测 量例如可以通过网络侧设备(例如在向电子设备200发送可选的测量通知后)控制持续发送例如图4所示的下一波束BN、测量单元230持续测量该下一波束的波束质量而进行(测量单元230例如可以基于测量通知所指示的时频资源和波束方向等接收并测量该下行波束)，这里不再赘述。
例如在电子设备200接收到使用波束确定的第二预定规则(在用户设备的位置到达覆盖交叠区域的进入侧边缘后下一波束的波束测量的结果高于第一阈值持续第一时段的情况下使用当前波束和下一波束两者)的情况下，在测量下一波束(例如图4所示的下一波束BN)的波束测量的过程中，电子设备200的测量单元230可以进一步在下一波束的波束测量的结果高于第一阈值持续第一时段的情况下，生成并利用收发单元210向网络侧设备发送第一测量结果报告，并且电子设备200的收发单元210可以从网络侧设备接收使用当前波束和下一波束两者发送的数据。
替选地或者附加地，例如在电子设备200接收到使用波束确定的第三预定规则(在用户设备的位置到达覆盖交叠区域的进入侧边缘后下一波束的波束测量的结果高于第二阈值持续第二时段的情况下仅使用下一波束)的情况下，电子设备200的测量单元230还可以进一步在下一波束的波束测量的结果高于第二阈值持续第二时段的情况下，生成并利用收发单元210向网络侧设备发送第二测量结果报告，并且电子设备200的收发单元210可以从网络侧设备接收仅使用下一波束发送的数据。优选地，第二阈值高于第一阈值以及/或者第二时段长于第一时段。
作为示例，电子设备200接收网络侧设备基于用户设备的位置与覆盖交叠区域的边缘之间的关系以及波束测量的结果而使用不同波束发送的数据的过程可以经由此前参照图8和/或图9所描述的示例信息交互流程实现。换言之，用于用户设备的电子设备200可以利用其收发单元210、位置信息生成单元220、测量单元230等实现参照图8和/或图9描述的示例交互中的UE的全部功能或处理，这里不再赘述。
在另一个示例中，例如根据使用波束确定的第四预定规则(在用户设备的位置到达覆盖交叠区域的进入侧边缘时使用当前波束和下一波束两者，并且在用户设备的位置到达离开侧边缘时使用下一波束)，网络侧设备可以仅基于用户设备的位置到达覆盖交叠区域的边缘，在不进行波束测量的情况下确定使用波束。
相应地，在本示例中，在接收到使用波束确定的第四预定规则的情况下，电子设备200可以在不进行波束测量的情况下，在用户设备的位置到达进入侧边缘后，例如利用收发单元210从网络侧设备接收使用当前波束和下一波束两者发送的数据；和/或在用户设备的位置到达离开侧边缘后，例如利用收发单元210从网络侧设备接收仅使用下一波束发送的数据例的。
作为示例，电子设备200接收网络侧设备仅基于用户设备的位置与覆盖交叠区域的边缘之间的关系而使用不同波束发送的数据的过程可以经由此前参照图10所描述的示例信息交互流程实现。换言之，用于用户设备的电子设备200可以利用其收发单元210、位置信息生成单元220、测量单元230等实现参照图10描述的示例交互中的UE的全部功能或处理，这里不再赘述。
在以上网络侧设备使用第二、第三或第四预定规则进行使用波束确定并且电子设备200接收到网络侧设备发送的关于第二、第三或第四预定规则的信息(例如与图5中关于当前波束的信息、关于下一波束的信息和关于覆盖交叠区域的边缘的信息一起提供)的示例中，电子设备200可以根据相应规则在无需基站实时通知的情况下了解基站侧实际使用的下行波束。电子设备200知晓实际的下行波束有利于其收发单元210使用相应波束进行下行数据的接收。
例如，在使用第二或第三预定规则的场景中，电子设备200在测量单元230生成相应的第一或第二测量结果报告的同时即了解基站侧实际使用的下行波束即为此前所接收的关于当前波束的信息和关于下一波束的信息所指示的“当前波束”和“下一波束”或者此前所接收的关于下一波束的信息所指示的“下一波束”。使用第四预定规则的场景中，电子设备200可以根据位置信息生成单元220监控的用户设备的位置而了解实际使用的波束。
此外，替选地或可选地，电子设备200可以从网络侧设备接收其使用改变了的波束进行数据传输之前再次发送的、针对实际的使用波束的波束指示以使知晓实际的使用波束，这里不再赘述。
此外，在以上第三或第四预定规则的示例中，在仅使用下一波束进行下行数据传输的情况下，认为用户设备已进入下一波束的覆盖区域并 且实现了波束切换，因此可以将下一波束设置为新的当前波束。此时，可选地，网络侧设备可以按照与此前描述的方式大致类似的方式再次进行确定用户设备的位置、当前波束和下一波束的处理以及确定覆盖交叠区域的边缘的处理。可选地，网络侧设备可以基于用户设备上报的位置信息和/或用户设备所在的交通工具的预定移动路径的信息而按照此前描述的方式类似地确定用户设备的位置、或者直接将其确定为离开侧边缘上的预测位置(例如图4所示的预测离开位置P2)，可以直接基于波束切换而确定用户设备的当前波束(例如图4所示的此前的下一波束BN设置为新的当前波束BC)，并且可以按照此前描述的方式类似地确定用户设备的下一波束以及覆盖交叠区域的边缘。可选地，电子设备200可以利用其收发单元210从网络侧设备接收上述方式确定的各项信息以供后续使用，这里不再赘述。
以上描述了根据本公开的实施例的用户侧的电子设备200，经由其与网络侧设备(基站侧设备)的交互，使得可以利用用户设备的位置与波束交叠区域之间的关系而使用适当的下行波束进行数据传输，这有利于减少对波束测量的依赖。
<4.第三实施例的信息处理设备的配置示例>
图12是示出根据本公开的第三实施例的信息处理设备的配置示例的框图。该信息处理设备可以用于为第一实施例的基站侧设备提供关于用户设备所处于的交通工具的预定移动路径的信息，并且例如可以是设置于核心网或云服务平台的服务器。
如图12所示，信息处理设备300可以包括收发单元310以及可选的控制单元320。收发单元310例如向信息处理设备300以外的设备发送信息和/或从信息处理设备300以外的设备接收信息。此外，尽管图中未示出，但信息处理设备300还可以包括存储单元。
这里，信息处理设备300的各个单元都可以包括在处理电路中。需要说明的是，信息处理设备300既可以包括一个处理电路，也可以包括多个处理电路。进一步，处理电路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。
根据本实施例，收发单元310可以向用于无线通信的电子设备(例 如根据第一实施例的基站侧的电子设备100)发送关于交通工具的预定移动路径的信息，以供该电子设备至少部分地根据所述信息确定处于所述交通工具上的用户设备(例如根据第二实施例的用户侧的电子设备200)的位置与用于用户设备的当前波束和下一波束的覆盖交叠区域的边缘之间的关系以使用当前波束和下一波束之一或两者向用户设备发送数据。
关于交通工具的预定移动路径的信息例如可以包括指示下述各项的信息：交通工具的标识符(ID)和/或移动路径的编号(航班号/车次等)、移动路径上的地理位置(以及可选的高度)、与移动路径上的地理位置(以及可选的高度)相关联的时间等等。可选地，该信息还可以包括指示移动方向(与移动路径上的地理位置(以及可选的高度)和时间相关联)的信息。
信息处理设备300可以例如经由各种适当方式获得交通工具的预定移动路径的信息。例如，信息处理设备300可以经由在控制单元320的控制下的收发单元310，从交通工具的运营者(航空公司、铁路公司、汽运公司、船运公司等等)或其他相关方定时地或周期性地获得关于交通工具的预定移动路径的信息，并且可以实时地获得交通工具的移动路径的更新信息。
信息处理设备300可以以各种适当方式向基站侧的电子设备提供关于交通工具的预定移动路径的信息。例如，信息处理设备300可以经由在控制单元320的控制下的收发单元310，周期性地、定时地(例如在交通工具进入基站侧的电子设备的覆盖范围之前的预定时间)、仅在移动路径更新时向基站侧的电子设备发送关于交通工具的预定移动路径的信息。
以上描述了根据本公开的第一至第三实施例的电子设备和信息处理设备。在本公开的一个变形例中，可以在交通工具上设置有代理装置或中继节点(例如IAB节点)等装置，该装置可以从第三实施例的信息处理设备(例如核心网或云服务平台的服务器)统一地获得关于交通工具的预定移动路径的信息。可选地，该装置可以将关于交通工具的预定移动路径的信息转发给交通工具上的所有的用户设备(例如具有第二实施例的电子设备的部分或全部功能)。此外，取代交通工具上的用户设备生成并向基站侧设备(例如具有第三实施例的电子设备的部分或全部功能)发送用户设备的位置信息，该装置可以生成并向基站侧设备发送交通工具的位置信息，以供基站侧设备使用。在适当时，该装置还可以进行基 站侧设备与交通工具上的用户设备之间的其它数据和/或信息的转发或中继，这里不再赘述。
