Description

一种无线通信的方法及装置
本申请要求于2020年7月17日提交中国国家知识产权局，申请号为202010694226.1，发明名称为“一种无线通信的方法及装置”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
本申请涉及通信技术领域，尤其涉及一种无线通信的方法及装置。
背景技术
卫星通信等非地面通信网络(non-terrestrial networks，NTN)具有全球覆盖、远距离传输、组网灵活、部署方便和不受地理条件限制等显著优点，其既可为固定终端，也可为各种移动终端提供服务。由于传统地面网络不能提供无缝覆盖，特别是在大海、沙漠、空中等无法部署基站的地方，非陆地网络被引入第五代移动通信(fifth generation，5G)系统等地面网络中，它通过将基站或者部分基站功能部署在高空平台或者卫星上为终端设备提供无缝覆盖，并且高空平台或者卫星受自然灾害影响较小，能提升5G系统的可靠性。
为了支撑广域覆盖，单颗卫星通常要配备几百甚至几千个波束，单星载荷大。为了缓解单星载荷小和覆盖范围广的矛盾，提高卫星系统资源使用效率，跳波束(beam hopping)卫星通信系统应运而生。具体来说，在跳波束卫星系统中，单颗卫星仅配备少量的波束(如几十个波束)，波束通过分时的方式服务单星的所有覆盖区域。在跳波束场景下，终端如何获取波束分布成为了亟待解决的问题。
发明内容

S300、网络设备确定第一波束配置信息。
网络设备根据其各个波束的跳波束的模式确定第一波束配置信息。
一种可能的实现中，该第一波束配置信息是由核心网下发的。具体地，核心网网元向网络设备发送第二波束配置信息，网络设备接收核心网网元发送的第二波束配置信息，并根据该第二波束配置信息确定所述第一波束配置信息。第一波束配置信息和第二波束配置信息均指示跳波束的模式，配置信息的表示形式可能相同也可能不同，本申请不做限制。
另一种可能的实现中，该第一波束配置信息是由网络设备与其他网络设备协商确定的。
S301、网络设备向终端发送第一波束配置信息，相应的，终端接收网络设备发送的第一波束配置信息。
第一波束配置信息可以包含具体的跳波束模式，或者跳波束模式的索引信息，或者波束模式的变动信息。下文中将详细说明不同的波束配置信息。
一种可能的实现中，网络设备向终端发送的第一波束配置信息，携带在无线资源控制(radio resource control，RRC)消息中。
携带第一波束配置信息的RRC消息可以是网络设备广播的消息。卫星通信中网络设备是运动的，不同时刻终端可能接收不同网络设备发射的波束，不同网络设备的波束模式不同，且卫星波束可能存在分裂或合成的情况，通过广播的RRC消息携带第一波束配置信息更加灵活，且能节省信令开销。
携带第一波束配置信息的RRC消息还可以是网络设备向终端设备单播的用户特定(UE-Specific)消息。在用户数量较少的场景下可以采用单播的RRC消息携带第一波束配置信息。
一种可能的实现中，网络设备周期性下发第一波束配置信息。举例来说，网络设备基于预先配置的周期广播系统消息，该系统消息中包含第一波束配置信息。通过周期性下发第一波束配置信息可以减少网络设备和终端之间的调度信令。
一种可能的实现中，终端向网络设备请求第一波束配置信息。举例来说，网络设备基于用户请求广播系统消息，该种基于用户请求广播的系统消息(on demand other system information，ODOSI)在小区建立后连续广播2个周期后停止广播，需通过终端请求后再次广播。例如，终端通过专用的前导码(preamble)触发网络设备广播ODOSI；或者终端通过 RRC系统消息请求消息RRC_SYS_INFO_REQ触发网络设备广播ODOSI。网络设备基于终端的请求下发第一波束配置信息不需要持续的下发波束配置信息，可以减少广播资源的开销。
S302、终端根据第一波束配置信息确定第一跳波束模式。
一种可能的实现中，第一波束配置信息中包含跳波束模式，终端将该跳波束模式确定为第一跳波束模式。
一种可能的实现中，第一波束配置信息中包含索引信息，终端根据该索引信息确定第一跳波束模式。
一种可能的实现中，第一波束配置信息中包含波束模式的变动信息，终端根据该变动信息确定第一跳波束模式。
第一跳波束模式用于指示网络设备的波束的激活信息。波束的激活信息可以包括激活波束的波束标识、激活波束对应的初始部分带宽(bandwidth part，BWP)、功率补偿系数等信息。还可包括波束特定(Beam-specific)的参数，如定时补偿，多普勒频移，极化方向等，本申请不做限制。
一种可能的实现中，第一跳波束模式与系统帧号相关。第一跳波束模式指示的波束的激活信息与系统帧号SFN对应，具体地，第一跳波束模式指示的激活波束通过mod(SFN,n)确定，其中mod()表示取模运算，SFN为系统帧号，n为跳波束模式变化周期。
S303、终端根据第一跳波束模式与网络设备进行通信。
终端根据第一跳波束模式指示的波束的激活信息确定服务波束的起止时间，并根据服务波束的起止时间确定通信状态，其中通信状态包括连接态(connected)或空闲态(idle)或非活动态(inactive)。
具体地，终端根据波束的激活信息，卫星的星历信息、当前位置信息以及波束的激活信息确定服务波束的起止时间。
需要指出的是，终端可以通过全球导航卫星系统(Global Navigational Satellite System，GNSS)等定位方式获得当前位置信息；终端可以通过预存的信息或者系统广播获得卫星的星历信息。本申请对星历信息或位置信息的获取方式不做限制。
举例来说，终端基于当前的位置信息、卫星的星历中包含的卫星的位置、运动规律等信息确定卫星可以提供覆盖的时间段；并根据第一跳波束模式指示的波束的激活信息，确定卫星提供覆盖时波束的分布情况，进而得到一个或多个服务波束提供服务的时间段。
终端根据服务波束的起止时间确定通信状态。举例来说，服务波束的起止时间可以表示当前位置上具有服务波束覆盖的时间段，即服务波束的服务时段。终端可以在服务波束的服务时段保持连接态，并在没有服务波束覆盖的时段，即非服务时段转换为空闲态或非活动态。一种可能的实现中，终端有通信需求时，在服务波束服务时段的开始时间，向网络设备发送随机接入请求。
图3所示的通信方法中，网络设备下发波束配置信息，终端根据该波束配置信息确定跳波束模式，并根据跳波束模式与网络设备通信，具体地，根据跳波束模式选择通信时机、调整通信状态，以达到节省功耗的效果。
如S301中所述，可以通过不同方式指示跳波束模式。下面详细介绍本申请实施例提供的波束配置方法。
本申请实施例提供了一种基于RRC信令的跳波束指示方法。该方法中卫星小区内的各个波束以系统帧为单位执行跳波束操作。跳波束模式指示的波束的激活信息与系统帧号对应。
网络设备通过广播RRC信令下发波束的跳变模式(hopping_pattern)，其中可以包含与系统帧对应的激活波束(Active Beam)的波束标识(beam ID)、激活波束对应的初始BWP、激活波束的功率补偿系统等参数。
本申请提供的一种实施例中，网络设备可以基于系统消息(system information block，SIB)下发波束配置信息。结合图3中的方法，该波束配置信息为第一波束配置信息。
举例来说，网络设备基于SIB_BeamConfig消息下发波束配置信息。具体格式如下：
Figure PCTCN2021105635-appb-000001
其中，Hopping Pattern表示跳波束模式，SystemFrame表示系统帧，系统帧与跳波束模式中指示的激活波束Active_Beam对应。具体地，上述SIB_BeamConfig消息中还包含激活波束的波束标识:BeamId。
需要指出的是，结合图3中的方法，上述Hopping Pattern为第一跳波束模式。
此外，跳波束模式还可以包含激活波束对应的初始部分带宽BWP和/或功率补偿系数。其中，初始BWP是用户首次接入波束时的频率资源，避免用户接入波束时搜索接入资源；功率补偿系数用于指示终端发射信号的功率大小，避免信号功率不足或过剩。
具体地，包含激活波束标识Hopping_BeamId对应的初始BWP的标识BWP_Id，例如Hopping_Beam_Id_0对应BWP_Id_0，Hopping_Beam_Id_1对应BWP_Id_1。激活波束对应的功率补偿系数由Beam_Power_Adjust以及对应的取值value表示，例如Beam0_Power_Adjust，Beam1_Power_Adjust等。
在一种可能的实现中，激活波束Active_Beam字段还可以用比特序列的形式表示，以节省比特开销(使用更少的字段)，例如采用以下格式：
Figure PCTCN2021105635-appb-000002
Active_Beam_bitmap是表示一串比特序列的变量名，其中BIT STRING(SIZE(maxNrofBeamInCell))表示比特串的长度，比特串的长度等于波束总数，即maxNrofBeamInCell。 该种实现方式中，比特位的值为1时表示对应波束是激活状态，比特位的值为0时表示对应波未激活，或者，比特位的值为0时表示对应波束是激活状态，比特位的值为1时表示对应波未激活。
一种可能的实现中，跳波束模式中包含多个系统帧对应的波束的激活信息。该种实现中的波束配置信息中包含更多的跳波束相关的信息，减少网络设备和终端之间的信令交互。
另一种可能的实现中，跳波束模式中包含一个系统帧对应的波束的激活信息。该种实现能够节省波束配置信息占用的比特。
网络设备向终端下发上述包含跳波束模式的波束配置信息，其中跳波束模式所指示的波束的激活信息与系统帧号有关。终端接收网络设备下发的波束配置信息后，根据系统帧号(system frame number，SFN)确定跳波束模式指示的波束的激活信息。
举例来说，终端通过mod(SFN,n)确定跳波束模式指示的波束的激活信息。其中n为跳波束模式变化周期。
参见图4，图4为本申请实施例提供的跳波束指示的一种示例。卫星小区内的各个波束以系统帧为单位执行跳波束操作。如图4所示，0号系统帧对应激活波束2和6，1号系统帧对应激活波束3和5，2号系统帧对应激活波束1和7，3号系统帧对应激活波束4，5号系统帧对应激活波束2和6，以此类推。
如图4所示的跳波束模式可以采用上述SIB_BeamConfig表示。示例性的，具体的RRC字段如下：
Figure PCTCN2021105635-appb-000003
上述字段中，0号系统帧SystemFrame-0对应的激活波束为2和6，Active_Beam(2,6)；1号系统帧SystemFrame-1对应的激活波束为3和5，Active_Beam(3,5)。
终端接收波束配置信息后，根据系统帧号确定第一跳波束模式指示的激活波束。举例来 说通过mod(SFN,n)确定激活波束，图4所示的场景中，n为4，因此SFN为0、4、8…时，终端确定激活波束为波束2和6；SFN为1、5、9…时，终端确定激活波束为波束3和5。
该实施例中，网络设备采用RRC信令广播携带跳波束模式的跳波束配置信息，能够灵活应对卫星移动以及波束变动等场景，同时节省信令开销。另外，将跳波束模式与系统帧联系起来，以时间为单位调整跳波束模式，便于调度。
参见图5，图5为本申请实施例提供的跳波束指示的另一种实施例。卫星波束可能存在波束分裂或波束合并的情况。波束分裂指将一个波束分裂为两个或两个以上的波束，波束合并指将两个或两个以上的波束合并为一个波束。在跳波束场景中，波束的分裂或合并将引起跳波束模式的变动。在本实施例中网络设备向终端下发上述跳波束的变动，以使得终端更新跳波束模式。
一种可能的实现中，网络设备可以基于SIB广播波束配置信息，该波束配置信息中包含跳波束模式的变动信息。举例来说，网络设备基于SIB_BeamConfig消息下发携带跳波束模式变动的波束配置信息。具体格式如下：
Figure PCTCN2021105635-appb-000004
其中字段Beam_splitting_combination表示波束分裂/合并。maxNrofBeamUpdate表示系统所支持的最多的更新波束的数量；BeamUpdate-Id表示波束更新标识；Beam_ID表示涉及分裂或合并的波束标识；Splitting表示波束分裂，一个波束可以分裂为两个或更多个波束，max_splitting_factor表示波束可以分裂的最大个数；Combination表示波束合并，两个或更多个波束可以合并为一个波束，max_combination_factor表示可以合并的波束的最大个数。CHOICE字段表示波束分裂Splitting和波束合并Combination为选择项，即二者选一。
需要指出的是，其中max_splitting_factor和max_combination_factor的取值可以由厂商根据实际情况决定，不同厂商可能采用不同的取值。
如图5所示，系统帧号3上，波束4、6和7合并为一个波束4。针对该场景，网络设备基于SIB_BeamConfig消息下发的携带跳波束模式变动的波束配置信息可以为如下所示：
Figure PCTCN2021105635-appb-000005
示例性的，波束4可以分裂为两个子波束(未在图中示出)。针对该场景网络设备基于SIB_BeamConfig消息下发的携带跳波束模式变动的波束配置信息可以为如下所示：
Figure PCTCN2021105635-appb-000006
Figure PCTCN2021105635-appb-000007
终端接收网络设备下发的上述携带跳波束模式变动信息的波束配置信息后，根据该配置信息更新跳波束模式，并根据更新后的跳波束模式与终端进行通信。
该实施例中，网络设备向终端下发的波束配置信息中携带波束变动信息，使得终端接收该波束变动信息后更新跳波束模式，实现网络侧与终端侧波束参数的匹配，保证了终端根据跳波束模式进行正常通信。
本申请提供的另一种实施例中，网络设备可以动态的指示跳波束模式。终端存储有一个或多个跳波束模式，跳波束模式用于指示波束的激活信息，上述一个或多个波束模式周期性的变化。网络设备下发携带索引信息的波束配置信息，终端根据该索引信息从一个或多个波束模式中确定出下一周期中使用的跳波束模式。
举例来说，如表1所示，可通过两个比特表示跳波束的索引，分别对应4种跳波束模式。跳波束的索引以及跳波束模式的映射关系可以是由协议规定的，也可以是网络设备和终端协商确定的。
表1
跳波束的索引 跳波束模式
00 模式1
01 模式2
10 模式3
11 模式4
终端存储有一个或多个跳波束模式。一种可能的实现中，网络设备向终端发送携带一个或多个跳波束模式的配置信息。举例来说，可以通过RRC消息配置给终端。可能的，上述一个或多个跳波束模式可以是协议中预先定义的，也可以是网络设备根据实际情况配置的。
网络设备向终端发送携带索引信息的波束配置信息，终端接收网络设备发送的携带索引信息的波束配置信息。一种可能的实现中，该波束配置信息通过用户特定(UE-Specific)的消息下发。举例来说，网络设备通过下行控制信息(downlink control information，DCI)下发索引信息，具体地，可以复用DCI中的Bandwidth part indicator字段。举例来说，网络设备还可以通过媒体接入控制(Media Access Control control，MAC)层控制信令MAC控制元素(MAC control element，MAC CE)下发索引信息。
终端根据索引信息从一个或多个波束模式中确定出下一周期中使用的跳波束模式。具体地，终端根据索引信息按照预定的映射关系确定下一周期中使用的跳波束模式。
该实施例中，终端基于索引信息动态获取跳波束的配置。相比于具体的跳波束模式，索引信息占用更少的比特。另外，通过UE-Specific消息向终端发送波束配置信息更加准确和灵活。
本申请提供的又一种实施例中，网络设备向终端发送的波束配置信息由核心网确定。核心网通过配置跳波束信息，提升网络内各个网络设备的协调能力。具体地，核心网向网络设备发送第二跳波束配置信息，网络设备接收之后，根据该第二跳波束配置信息确定第一跳波束配置信息，并向终端下发第二跳波束配置信息。
一种可能的实现中，核心网网元通过下一代应用协议(NG Application Protocol，NGAP)接口传输跳波束配置信息。具体地，定义新的跳波束Beamhopping消息，用于向网络设备传输跳波束配置信息。
示例性的，可以通过表2所示的消息配置跳波束信息。核心网网元下发的配置信息可以包括系统帧号(System Frame Number)、激活波束标识(Active_Beam_ID)、激活的初始BWP(Active_Initial_BWP)和功率补偿(Power_Adjust)等信息单元(information element，IE)。表2中上述四个信息单元为必选(M)项，在另一种可能的实现中，功率补偿可以是可选项。系统帧号的范围可以为0～1023，也可以为其他范围。激活波束标识的范围为1～maxNrofBeamInCell，其中maxNrofBeamInCell表示小区内波束数量的最大值。上述配置信息还可以包含其他的信元，本申请不做限制。
需要指出的是，表2所示的分配的重要性(assigned criticality)表示对应信元无法解读时采用的处理方式，可以为拒绝(Reject IE)、忽略并通知发送者(Ignore IE and Notify Sender)或者忽略(Ignore)。在一种可能的实现中表2所示的各信元对应的分配的重要性为“忽略”。
在一些可能的实现中，核心网网元下发的配置消息包含表2的部分列，或者在表2的基础上增加了其他列，本申请不作限制。

Figure PCTCN2021105635-appb-000009
在另一种可能的实现中，网络设备向终端下发的波束配置信息还可以由网络内各个网络设备之间协商确定的。网络设备之间通过Xn应用协议(Xn Application Protocol，XnAP)接口进行协商。
该实施例中，网络设备向终端下发的波束配置信息由核心网确定或者由网络内各个网络设备协商确定，实现了网络内各个网络设备的协调能力的提升。
