Description

一种波束信息指示方法及装置 技术领域
本发明涉及无线通信领域，尤其涉及无线通信中的波束信息指示方法及相关装置。
背景技术
卫星通信具有全球覆盖、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，已经被广泛应用于海上通信、定位导航、抗险救灾、科学实验、视频广播和对地观测等多个领域。同时，未来地面第五代移动网络(5G)将具备完善的产业链、巨大的用户群体、灵活高效的应用服务模式等。卫星通信系统与5G相互融合，取长补短，共同构成全球无缝覆盖的海、陆、空、天一体化综合通信网，满足用户无处不在的多种业务需求，是未来通信发展的重要方向。特别地，下一代卫星网络呈现超密组网特性，卫星网络的规模从铱星星座的66颗发展到一网(Oneweb)星座的720颗，并最终延展到超过12000颗的星链(Starlink)超密低轨卫星星座。
在卫星通信系统中，高效的干扰管理是提升系统吞吐的核心技术。为了减少干扰，卫星通信中采用频率和极化复用，常用的方案为多色复用。多色复用是指用颜色来指示波束对应的频率或极化方式，其中，一种颜色可以代表一种频率或一种极化方式，例如左旋圆极化(Left Hand Circular Polarization，LHCP)或右旋圆极化(Right Hand Circular Polarization，RHCP)。在卫星动态场景下，波束的颜色复用信息需要动态调整，波束的颜色复用信息是指卫星的所有波束对应的频率和极化方式等信息，卫星可以每隔一定时间动态调整并广播自身的颜色复用信息或提前下发后面一段时间内颜色复用信息，在这个过程中会引入信令开销过大的问题，对于大规模波束系统(几百甚至几千波束)不可取。
发明内容
本申请提供一种波束信息指示方法及装置，可以应用于无线通信领域，尤其在卫星通信的干扰管理中能够有效地节省信令开销。

本申请实施例通过获取多个波束的基准域信息和每个时刻对应的第一偏移量实现多个波束域信息在每个时刻的更新，由于指示偏移量相比于域信息本身而言，所需的指示开销更小，因此，相比于每个时刻直接下发所有波束的域信息或某一时刻下发一段时间内的所有波束的域信息节省了信令开销。
结合上述第一方面，在一种可能的实现方式中，所述第一偏移量是相对于基准域信息标识的偏移值或所述基准域信息的偏移值。

具体实施方式
下面结合本发明实施例中的附图对本发明实施例进行描述。本发明的实施方式部分使用的术语仅用于对本发明的具体实施例进行解释，而非旨在限定本发明。
图1为本发明实施例涉及的一种卫星通信系统，该卫星通信系统包括用户设备(UE)和网络设备，其中，网络设备可包括一个或多个卫星节点(例如可为NGEO卫星)和核心网设备，UE可与卫星节点进行无线通信，卫星节点可与核心网设备进行无线通信，其中：
卫星节点可包括用于对信息进行中继的轨道接收机或中继器，卫星节点可与核心网设备进行通信交互，向UE提供通信服务。
核心网设备例如为现有的移动通信架构(如5G网络的3GPP接入架构)的核心网(core network，CN)中的设备或未来移动通信架构中的核心网中的设备。核心网作为承载网络提供到数据网络的接口，为用户设备(UE)提供通信连接、认证、管理、策略控制以及对数据业务完成承载等。其中，CN又进一步可包括：接入和移动管理网元(Access and Mobility Management Function，AMF)、会话管理网元(Session Management Function，SMF)，认证服务器网元(Authentication Server Function，AUSF)、策略控制节点(Policy control Function，PCF)、用户面功能网元(User Plane Function，UPF)等等网元。其中，AMF网元用于管理UE的接入和移动性，主要负责UE的认证、UE移动性管理，UE的寻呼等功能。
UE可以是终端设备(Terminal Equipment)、通信设备(Communication Device)、物联网(Internet of Things，IoT)设备中的任意一种。其中终端设备可以是智能手机、蜂窝电话、智能手表、智能平板、个人数字助理电脑、膝上型电脑等等；通信设备可以是服务器、网关(Gateway，GW)、控制器、无线调制解调器等等；物联网设备可以是传感器、可移动性装置(如自行车/汽车/载具)等等。
同样的，本发明实施例也可以应用于地面通信系统，例如，该通信系统可以为第三代合作伙伴计划(3rd generation partnership project，3GPP)通信系统，例如，长期演进(long term evolution，LTE)系统，又可以为5G移动通信系统或者新空口(new radio，NR)系统或者未来通信系统，本申请不予限制。网络设备可以包括但不限于：演进型节点B(evolved node B,eNB)，基带单元(baseband unit，BBU)，无线保真(wireless fidelity，WIFI)系统中的接入点(access point，AP)、无线中继节点、无线回传节点、传输点(transmission point，TP)或者传输接收点(transmission reception point，TRP)等。该网络设备还可以为5G系统中的gNB或TRP或TP，或者5G系统中的基站的一个或一组(包括多个天线面板)天线面板。此外，该网络设备还可以为构成gNB或TP的网络节点，如BBU，或分布式单元(distributed unit，DU)等。或者，该网络设备还可以是设备到设备(device-to-device，D2D)通信系统、机器到机器(machine to machine，M2M)通信系统、物联网(Internet of Things，IoT)、车联网通信系统或者其他通信系统中承担网络侧功能的设备。
还需要说明的是，为了说明书的简洁，本文主要以图1所示的卫星通信系统为基础进行技术方案的描述。
下面对本申请涉及的卫星波束干扰管理进行简要说明。
卫星通信系统中，为了提升系统容量，卫星通常配备大规模天线阵列系统，并同时形成多个波束，为不同的用户提供传输。在多波束卫星通信系统中，由于远近效应不明显，小区中心和小区边缘的用户信号强度差别不大，若采用现有地面LTE或5G系统的全频复用方式，会产生很强的波束间干扰和星间干扰，卫星网络采用频率和极化复用的方式来减少干扰。
图2示意了卫星通信中常用的多色复用方案(多种颜色在图中示意为a、b、c、d)。一种颜色代表一种频率和极化方式的组合。其中，多色复用方案中的颜色复用阶数N＝i 2+j 2+i*j，i和j取正整数。图2为四色复用，即N＝4，对应4种频率和极化方式的组合。具体地，波束1和波束5都采用频率f1和RHCP极化方式，f1和RHCP组合对应颜色a；波束2和波束6都采用频率f1和LHCP极化方式，f1和LHCP组合对应颜色c；波束3和波束7都采用频率f2和RHCP极化方式，f2和RHCP组合对应颜色b；波束4和波束8都采用频率f2和LHCP极化方式，f2和LHCP组合对应颜色d。
以61波束卫星系统下发的颜色复用方案信息为例，对颜色复用方案做进一步说明。表1示出了每个时刻下每个波束对应的颜色信息，颜色信息表示频率和极化方式。
表1
Figure PCTCN2021102702-appb-000001
卫星每个时刻按照表1中的信息下发所有波束的频率和/或极化方案，或在某一时刻下发后面一段时间所有波束的频率和极化方案，信令开销大。
针对现有技术中卫星通信颜色复用方案存在的问题，本申请提供一种波束信息指示方法，该方法可以在实现波束颜色复用的同时节省信令开销。具体的，本申请提供的波束信息指示方法通过引入第一偏移量来指示多个波束的域信息相对于该多个波束的基准域信息的偏移值，由该多个波束的基准域信息和第一偏移量可以更新该多个波束的域信息。
需要说明的是，在应用到卫星通信领域时，本申请实施例涉及的波束的域信息可以对应理解为卫星通信中颜色复用方案的颜色信息，波束的基准域信息可以理解为基准颜色信息，后面在描述时两者可以互换，在此做统一说明，下面不再赘述。
具体的，下面将结合附图对本申请的实施例进行描述。
如图3A所示，本申请提供的波束信息指示方法包括：
S3A01、第一通信装置获取第一偏移量。
第一通信装置接收第二通信装置发送的第一偏移量，该第一偏移量用于指示多个波束的域信息相对于该多个波束的基准域信息的偏移值。波束的域信息包括以下信息中的一个或多个：时域信息、频域信息、极化域信息。
应理解，本申请实施例提供的方法可以应用于无线通信系统和卫星通信系统中。
示例性的，第一通信装置可以为终端设备或芯片，第二通信装置可以为网络设备或芯片，网络设备例如为卫星，下面以第一通信装置为终端设备，第二通信装置为卫星为例进行说明。
一种实现方式中，卫星在初始时刻或某一基准时刻发送基准域信息和后面一段时长内每个时刻分别对应的第一偏移量。相应的，终端设备接收卫星下发的基准域信息和后面一段时长内每个时刻分别对应的第一偏移量。
又一种实现方式中，卫星在初始时刻或某一基准时刻发送基准域信息，在初始时刻或某一基准时刻之后的每个时刻发送当前时刻对应的第一偏移量。相应的，终端设备在初始时刻或某一基准时刻接收基准域信息，在初始时刻或某一基准时刻之后的每个时刻对应接收卫星发送的第一偏移量。
需要理解的是，波束的基准域信息可以看作是终端设备在初始时刻或基准时刻获取的域信息，也可以是在当前时刻之前确定的域信息。示例性的，根据初始时刻或基准时刻获取基准域信息和第一偏移量确定某一时刻的域信息，该域信息可以看作是该某一时刻的下一时刻对应的基准域信息。其中，初始时刻可以为卫星开始通信时的时刻，基准时刻可以为某一个指定时刻。当前时刻之前，可以是当前时刻的上一个时刻，或者当前时刻之前的任一时刻。
可选的，终端设备也可以从其他终端设备获取基准域信息和/或第一偏移量，例如设备到设备(Device to Device，D2D)场景，通过侧行链路(Sidelink，SL)实现信息传输，本申请对此不做限定。
一种可能的实现方式，时域信息包括帧或子帧或时隙或微时隙(mini-slot)或符号，频域信息包括频率或频点，极化域信息包括LHCP和RHCP中的至少一种。
需要说明的是，本申请中提到的“时刻”是时间概念，具体指某一个时间点t1或某一时间段Δt，而时域信息是指与时域资源有关的信息，例如帧或子帧或时隙或微时隙或符号信息。
一种实现方式中，第一偏移量是相对于基准域信息标识的偏移值。具体的，第一偏移量为第一偏移量标识。基准域信息标识的取值范围与第一偏移量的取值范围相同。其中，基准域信息标识的取值范围可以对应理解为颜色复用方案中的颜色阶数。例如，四色复用对应的颜色阶数为4，也就是说基准域信息标识/第一偏移量标识的取值范围为4，可以用2个比特来表示，如00，01，10，11。本实施例中，基准域信息标识还可以称为基准域信息索引，第一偏移量标识也可以称为第一偏移量索引。
示例性的，表2给出四色复用方案中每种颜色复用信息对应的标识。其中，在该示例中颜色复用信息为频点和极化方式的组合。具体的，标识00表示频点f1和LHCP极化方式的组合，标识01表示频点f1和RHCP极化方式的组合，标识10表示频点f2和LHCP极化方式的组合，标识11表示f2和RHCP极化方式的组合。四色复用就是多个波束复用这四种频点和极化方式的组合。
又例如，表3给出的颜色复用信息为频点，此时不区分极化方式。其中，标识00，01，10，11分别对应不同的频点f1，f2，f3，f4。
又例如，表4给出的颜色复用信息为时隙和频点，标识00，01，10，11分别对应不同的时隙和频点组合t1和f1，t2和f2，t3和f3，t4和f4。
需要说明的是，表2、表3和表4仅是示例性说明，不对本申请方案构成限定，例如，不仅是四色复用，也可以是多色复用，也就是频点和极化方式的组合不仅只有四种，可以为多种，颜色复用信息也可以为频率等。

01 时隙t2，频点f2
10 时隙t3，频点f3

需要理解的是，颜色复用信息是指卫星波束复用的颜色信息，也就是本申请中波束复用的域信息，以61波束卫星系统为例，例如61个波束复用表2所示的4种颜色信息；基准颜色信息是指所有波束复用颜色复用信息后对应的波束颜色信息，例如表5所示。
一种可能的实现方式，颜色复用信息和标识的映射关系表可以包含在波束基准域信息中，与波束基准域信息一同下发或分别下发。具体的，当颜色复用方案发生变化时，例如颜色复用信息变化或颜色复用阶数发生变化，颜色复用信息和标识的映射关系表进行更新。
可选的，颜色复用信息和标识的映射关系表也可以预先配置给终端设备，波束基准域信息标识对应的具体信息可以由预先配置的颜色复用信息和标识映射关系表得到。
示例性的，第一偏移量对基准域信息标识进行偏移。其中，基准域信息标识基于第一偏移量进行偏移后得到新的域信息标识，该新的域信息标识的取值在颜色复用信息对应的标识的取值范围内，从而实现颜色信息复用。
可选的，可以采用第一偏移量与基准域信息标识相加后再对颜色阶数取余的方法得到新的域信息标识。
具体的，以表5给出的61波束卫星系统四色复用方案为例进行说明。其中，基准域信息 以其标识的形式给出，每个标识对应的颜色复用信息例如为表2所示。如表5所示，时刻1对应61个波束的基准域信息，时刻2对应偏移量01，偏移量01指示了在时刻2时61个波束的基准域信息的标识进行01的偏移，进而得到时刻2下61个波束的域信息标识。例如，波束2的基准域信息标识为11，时刻2对应的偏移量为01，则时刻2下波束1对应的域信息标识为mod(11+01，4)＝00，其中，mod()表示取余运算，4表示颜色复用方案中的颜色阶数。也就是说，在时刻2时，波束2对应的域信息为标识00对应的颜色复用信息，例如为表2中的频点f1和LHCP极化方式的组合。类似的，在时刻t时波束2对应的域信息标识为mod(11+11，4)＝10，则时刻t时波束2对应的域信息为频点f2和LHCP极化方式的组合。又例如，如果表5中每个标识对应的颜色复用信息为表4所示的时隙和频点信息，类似的，时刻2对应偏移量01，则波束1偏移后得到的新的域信息标识为01，也就是说，波束1在时刻2时对应在时隙t2，频点f2进行传输。
表5
Figure PCTCN2021102702-appb-000002
又一种可能的实现方式，如图3B所示，可以执行以下步骤实现波束域信息的更新：
S3B01：卫星可以直接发送多个波束对应的域信息标识，即卫星通知终端设备所有波束对应的域信息标识，不是采用前述实施例中所述的除基准时刻发送所有波束对应的域信息标识，其他时刻发送相对于基准域信息的偏移量的方式。其中，当前时刻的上一时刻对应域信息标识相同的几个波束，在当前时刻该几个波束仍具有相同的域信息标识。可选的，当前时刻该几个波束具有的域信息标识与当前时刻该几个波束对应的域信息标识相同或不同。
相应的，终端设备接收卫星发送的多个波束对应的域信息标识。
可选的，卫星在每个时刻分别发送波束对应的域信息标识，或在某一时刻下发后面一段时长内的所有波束的域信息标识。
S3B02：终端设备基于多个波束的域信息标识实现波束域信息的更新。
示例性的，如表6所示，时刻1，卫星下发61个波束对应的域信息标识，其中，波束1和波束58对应的域信息标识相同。类似的，波束2-4和波束59-61对应的域信息标识也分别相同；时刻2，卫星下发更新后的61个波束对应的域信息标识，其中，波束1-4和波束58-61对应的波束域信息标识分别相同，但与时刻1时对应的域信息标识不同。具体的，域信息标识对应的域信息例如可以从表2中颜色复用信息和标识的映射关系表中得到。
基于上述实施例，卫星通过每个时刻下发更新后的波束域信息标识或某一基准时刻下发后面一段时长内的波束域信息的标识，相比于直接下发波束域信息节省了信令开销。
表6

Figure PCTCN2021102702-appb-000004
又一种可能的实现方式，如图3C所示，可以执行以下步骤实现波束域信息的更新：
S3C01：卫星发送基准复用信息标识跳变值，该基准复用信息标识跳变值用于指示变化后的基准复用信息标识。
相应的，终端设备接收基准复用信息标识跳变值。
需要说明的是，基准复用信息可以理解为例如表2-表4所示的颜色复用信息。基准复用 信息标识可以为基准时刻或初始时刻对应的复用信息标识，也可以为当前时刻之前对应的复用信息标识。其中，初始时刻可以为卫星开始通信时的时刻，基准时刻可以为某一个指定时刻。当前时刻之前，可以是当前时刻的上一个时刻，或者当前时刻之前的任一时刻。
S3C02：终端设备基于基准复用信息标识跳变值更新每个时刻的波束域信息。
示例性的，以四色复用方案为例进行说明，其中，表7中的标识指示的具体颜色复用信息以表2为例。卫星发送基准时刻后每个时刻对应的标识变化，进而实现波束域信息的更新。例如，在时刻2时，卫星发送相对于基准时刻的标识变化后的值，如时刻1时的标识00在时刻2时变为标识01，时刻1时的标识01在时刻2时变为标识10等，需要说明的是，标识本身指示的颜色复用信息可以不发生变化。以61波束系统为例，也就是说，在时刻1时复用标识00对应的颜色信息的波束，在时刻2时复用标识01对应的颜色信息。
表7
时刻1(基准时刻) 时刻2 …… 时刻t
00 01 …… 11
01 10 …… 10
10 11 …… 00
11 00 …… 01
上述实施例中，通过对颜色复用信息进行标识设置，卫星在下发波束域信息时可以直接下发每个波束对应的标识，由标识来指示具体对应的颜色复用信息，相比于现有技术中直接下发颜色复用信息节省了一定的信令开销。具体的，以表1、表6和表7为例来说明，表1为现有技术方案中波束域信息的下发方式，每个时刻下发具体的波束域信息，例如频率信息为2比特(bit)，可以表示3种或4种不同的频点，极化信息为1比特，例如可以表示如LHCP或RHCP的极化方式，每个时刻更新61个波束域信息需要的开销为61*(2+1)＝183bit；表6为以波束域信息标识的形式更新每个时刻对应的域信息，需要的开销为61*2＝122bit，以波束域信息标识的形式更新每个时刻对应的域信息相比于现有技术方案在一定程度上节省了信令开销，并且也可以实现颜色信息的复用；表7中发送每个时刻基准复用信息标识变化后的值，使当前时刻之前具有相同基准复用信息标识的波束在当前时刻具有统一的基准复用信息标识变化，从而实现波束域信息的更新。其中，每个时刻更新基准复用信息标识变化所需要的开销为16bit，进一步节省信令开销；更进一步的，通过第一偏移量来指示波束域信息的更新能够在实现颜色信息复用的基础上极大地节省信令开销。以表5为例，卫星下发基准域信息后(以基准域信息对应的标识进行下发)，可以下发一段时长内每个时刻对应的第一偏移量或每个时刻下发当前时刻对应的第一偏移量，利用第一偏移量对基准域信息标识进行整体的偏移。基准时刻后的每个时刻仅需2bit的开销就可以实现所有波束域信息的更新，尤其对于大规模波束系统(几百甚至几千波束)，极大的节省了信令开销。另外，相同颜色复用信息对应的几个波束进行同样的偏移，可以保证偏移后该几个波束仍具有相同的颜色复用信息，并且该几个波束与偏移之前间隔相同的距离，有效的解决卫星通信中小区中心和小区边缘用户信号强度差别不大带来的波束干扰。
另一种可能的实现方式中，第一偏移量也可以是相对于基准域信息的偏移值。其中，第一偏移量具体为一个偏移值，例如相对于频率或频点的偏移值，或者相对于帧或子帧或时隙或微时隙(mini-slot)或符号的偏移值，本申请在此不做限定。第一偏移量直接对基准域信息 进行偏移降低了计算复杂度。
一种可能的实现方式中，终端设备获取第二偏移量，第二偏移量与第一偏移量不同，第二偏移量用于指示多个波束之外的至少一个波束的域信息相对于该至少一个波束的基准域信息的偏移。也即，终端设备可以接收第一偏移量和第二偏移量，其中，第一偏移量对应其支持的所有波束中的一部分波束，第二偏移量对应其支持的所有波束中的另一部分波束。
示例性的，表8中波束1-40在时刻2对应的第一偏移量为01，波束41-61在时刻2对应的第二偏移量为10，波束1-40在时刻t对应的第一偏移量为11，波束41-61在时刻t对应的第二偏移量为00。
表8

上述实施例用第一偏移量和第二偏移量来指示所有波束域信息的偏移值，可以适用于跳波束卫星系统，不同簇波束对应各自的偏移量，有利于减少不同簇波束之间的波束干扰，同时在波束域信息更新的过程中可以节省信令开销。
同样的，第一偏移量和第二偏移量可以为偏移量标识或具体的偏移值。
需要说明的是，上述实施例仅是示例而非限定，第一偏移量和第二偏移量对应的波束组合有多种形式，本申请在此不再赘述。
此外，第一偏移量和第二偏移量仅为举例，针对终端设备所支持的波束数量，还可以设置更多的偏移量。
一种可能的实现方式中，波束的域信息承载在部分带宽BWP信元中。也可以理解为，BWP配置信息中携带了波束的域信息。可选的，每种域信息对应一个BWP配置，例如四色复用方案中，四种颜色复用信息分别对应BWP0、BWP1、BWP2、BWP3的配置信息。
可选的，承载在BWP信元中的波束域信息的标识可以为BWP配置信息中包含的标识，也可以是为每个波束域信息重新设置的标识，标识的设置可以参考前述实施例，在此不再赘述。
可选的，承载在BWP信元可以承载具体的波束域信息，例如承载波束的时域信息、频域信息、极化域信息中的一种或多种的组合。
示例性的，如表9所示，四色复用方案中，00，01，10，11分别为BWP0，BWP1，BWP2，BWP3对应的标识。如表10所示，其中，每组波束复用一个BWP配置信息，例如，波束1-10采用BWP0的配置信息，波束53-61采用BWP3的配置信息，BWP0～BWP3在每个时刻对应 同一个偏移量。例如，时刻2时的偏移量为01，对于波束1-10经过01偏移后得到新的标识为01，也就是说，在时刻2，波束1-10复用BWP1的配置信息。

可选的，每个BWP配置对应同一个偏移量或每个BWP配置分别对应一个偏移量或多个BWP配置之外的至少一个BWP对应第二偏移量。
示例性的，BWP0和BWP1对应第一偏移量，BWP2和BWP3对应第二偏移量。如表11所示。

需要说明是，上述实施例中的61波束系统仅为示例，本申请提供的方法可以应用于任意波束系统，例如16波束系统、32波束系统、48波束系统等，本申请在此不做限定。
一种可能的实现方式，波束信息按周期更新，所述波束信息包括所述基准域信息、所述第一偏移量、波束个数中的至少一个。一种可能的实现方式，当前周期的多个波束的基准域信息与当前周期之前周期的该多个波束的基准域信息相同。
一种可能的实现方式，当前周期的多个波束的基准域信息与当前周期之前周期的该多个波束的基准域信息不同。
一种可能的实现方式，当前周期的多个波束的第一偏移量的取值与当前周期之前周期的该多个波束的第一偏移量的取值不同。
一种可能的实现方式，当前周期的多个波束的第一偏移量的取值与当前周期之前周期的该多个波束的第一偏移量的取值相同。
一种可能的实现方式，当前周期第一偏移量的取值范围与当前周期之前周期的偏移量的取值范围不同。
示例性的，第一偏移量的取值范围不同可以对应理解为颜色复用阶数发生变化。例如，当前周期之前周期为当前周期的前一个周期，当前周期的前一个周期采用四色复用，当前周期采用三色复用，也就是说，当前周期的第一偏移量的取值范围为3，可以用2个bit来表示，例如为00，01，10，11。示例性的，11可以保留，使用00，01，10来指示三种颜色复用信息。需要说明的是，上述仅是示例，可以按照具体应用对标识进行设置和使用，本申请对此不进行限定。当前周期的前一个周期的第一偏移量的取值范围为4，例如为00，01，10，11。如表12所示，T为一个周期，在t11-t1T周期内，波束的基准域信息对应4种BWP配置信息，为四色复用方案；在t21-t2T周期内，波束的基准域信息对应3种BWP配置信息，为三色复用方案。

基于上述实施例，通过对波束信息的周期性更新，可以根据具体的干扰状态或终端设备需求实现波束颜色复用方案的动态调整，进而达到有效的进行波束干扰管理。
需要说明的是，以上表格在实际应用中可以使用其中部分行。另外，上述表格中的基准 域信息、偏移量、颜色复用信息(频率和/或极化方式、BWP等)和标识之间的映射关系以及波束采用的域信息仅仅是示例，本申请在此不做限定。一种可能的实现方式，当前周期的多个波束的第一偏移量的取值范围与当前周期之前周期的该多个波束的第一偏移量的取值范围相同。
一种可能的实现方式，当前周期的波束个数与当前周期之前周期的波束个数不同。
示例性的，卫星间干扰较大时，卫星对边缘波束进行关闭，波束个数发生变化；或者，卫星进行波束动态调整时，波束个数发生变化。
一种可能的实现方式，当前周期的波束个数与当前周期之前周期的波束个数相同。
一种可能的实现方式，当前周期的多个波束基准域信息与当前周期之前周期的该多个波束的基准域信息相同，当前周期的多个波束的基准域信息对应的第一偏移量的取值与当前周期之前周期的该多个波束对应的第一偏移量的取值相同。
基于上述实施例，有利于刚接入卫星网络的终端设备获得与已接入卫星网络的终端设备一致的波束的基准域信息和偏移量，减少波束干扰。

上述实施例为本申请提供的一种波束信息指示方法，在卫星动态变化的场景下，当卫星运动在赤道附近或者相邻卫星之间的星间距较大时，卫星之间的波束重叠比较少，因此带来的星间波束干扰也较少，利用本申请提供的波束信息指示方法，可以有效地节省波束信息更新带来的信令开销。根据上述实施例的描述，本申请提供的方法实现了波束颜色信息的复用，复用相同颜色信息的波束间存在一定的距离，有效的减少波束干扰，进而实现卫星的波束干扰管理。
另外，本申请提供的波束信息指示方法可以应用到多种场景实现波束干扰管理，示例性的，利用本申请提供的方法减少星间波束之间的干扰，例如服务卫星采用基准颜色信息，邻卫星采用基于第一偏移量对基准颜色信息偏移后的颜色信息，这样两个卫星之间复用相同颜色信息的波束之间存在一定距离，减少两个卫星之间的波束干扰；又例如，卫星在某一基准时刻t1采用基准颜色信息，在时刻2利用偏移量对基准颜色信息进行偏移得到新的颜色信息，减少同一卫星波束之间的干扰。
当卫星从低纬度区域运动到高纬度区域时，或者当卫星数量较多，相邻卫星之间的星间间距较小，不同卫星之间的重叠区域显著增加，星间干扰也随之大幅增加，极大地限制了网络性能。
基于此，本申请还提供一实施例，将波束信息指示方法与波束开关相结合，其中，波束开关是指根据卫星之间的重叠覆盖区域是否变大，决策是否关闭卫星边缘的部分波束，以此来减少卫星不同波束间的干扰。
示例性的，图4为波束开关的示意图。如图4所示，卫星1、卫星2和卫星3之间的重叠覆盖区域较大，此时卫星2需要关闭外侧的波束(图中以数字1-6来示意要关闭的波束)，这样可以减少卫星之间的干扰。波束信息指示方法与波束开关相结合，一方面，可以减少卫星动态运动场景下的星间干扰；另一方面，卫星检测到干扰后，需要对波束颜色复用信息进行更新，根据本申请提供的波束信息指示方法，可以进一步减少更新波束信息带来的信令开销，同时实现波束的干扰管理。
具体的，如图5B所示，本申请提供一种波束开关方法，该方法包括：
S5B01：第三通信装置获取其他通信装置的位置信息。
需要说明的是，其他通信装置是指第三通信装置之外的通信装置。
示例性的，上述通信装置可以为卫星，下面以第三通信装置为第一卫星，其他通信装置为第一卫星之外的其他卫星为例进行说明。其中，图5B中以第一卫星和其他卫星示意，其中，其他卫星包含多个卫星。
S5B02:第一卫星根据该第一卫星的位置信息和其他卫星的位置信息确定该第一卫星的覆盖区域。
一种可能的实现方式，卫星的覆盖区域基于冯洛诺伊(Voronoi)图确定。
可选的，Voronoi图为二维或三维。示例性的，如图5A所示，卫星1-卫星10基于位置信息确定二维Voronoi图，如图5A中实线所示。其中，以卫星1为第一卫星为例，卫星1包含61个波束，其中波束中心点位于卫星1对应的Voronoi图内的波束开启，如图5A中的“*”点所示；波束中心点位于卫星1对应的Voronoi图之外的波束关闭，如图5A中的“+”点所示。其他卫星的波束开关规则与卫星1相同，在此不再赘述。
基于上述方案，利用Vorionoi图确定卫星的覆盖区域，进而判断波束中心点是否在卫星对应的Vorionoi图内来进行波束的开启或关闭，实现方式简单，并且基于Vorionoi图的方法实现波束开关不但可以最小化星间干扰，还可以保障卫星波束的全覆盖。
一种可能的实现方式，卫星的覆盖区域基于矩形或椭圆形等形状确定。
可选的，矩形或椭圆形对应大地坐标系(即二维经纬度平面)下卫星的覆盖/服务区域。
一种可能的实现方式，若时间变化大于预设值，或，第一卫星和其他卫星之间的位置变化大于预设值，则第一卫星更新Voronoi图。
基于上述方案，可以实现卫星Voronoi图的动态更新，在卫星动态变化时，由动态更新的Voronoi图来调整波束的开启或者关闭，进而达到最优的波束干扰管理。
一种可能的实现方式，第一卫星将波束开关信息发送给其他卫星，该波束开关信息为Voronoi图扩张或收缩后的端点位置或偏移值，该偏移值用于指示扩张或收缩后的Voronoi图相对于扩张或收缩前的Voronoi图的偏移量。
基于上述方案，第一卫星根据自身的负载能力对Voronoi图进行扩张或收缩，并将扩张或收缩后的Voronoi图的信息在卫星之间进行传输，有利于在减少星间干扰的同时进一步实现负载均衡。
一种可能的实现方式，该波束开关信息承载在XnAP消息中的覆盖模式(CoveragePattern)信元中。
示例性的，CoveragePattern信元格式如下：
Figure PCTCN2021102702-appb-000012
Figure PCTCN2021102702-appb-000013
其中，Pattern_location表示卫星扩张或收缩后的Voronoi图的端点位置，Offset表示卫星扩张或收缩后的Voronoi图相对于卫星扩张或收缩前的Voronoi图的偏移值。其中，端点位置信息可以表示为经纬度或地心地固坐标系(Earth Centered Earth Fixed，ECEF)下的(x，y，z)等形式。
S5B03：第一卫星根据波束中心点是否在该第一卫星的覆盖区域内确定波束的开启或关闭。
上述实施例为本申请提供的波束开关方法，利用Voronoi图确定卫星覆盖范围，进而根据波束中心点是否在Voronoi图内决定波束的开启或关闭，该波束开关方法不仅可以保障卫星波束的覆盖范围，避免关闭波束后相邻波束之间存在一定间隙，导致波束覆盖不足，而且可以减少卫星间干扰。
本申请提供又一实施例，将本申请提供的波束开关方法与现有卫星通信中多色复用方法相结合，利用本申请提供的波束开关方法可以减少卫星之间的波束干扰，另外，基于Voronoi图的波束开关方法在实现波束开启和关闭时可以保障波束的全覆盖，避免开启的波束之间存在距离过大，导致覆盖范围不足。进一步的，与多色复用方法相结合，可以通过对颜色信息的复用，进一步减少波束干扰。
如图6所示，本申请又提供一种将波束信息指示方法与波束开关方法相结合，以实现波束干扰管理的方法，其中，本申请实施例不限于两个卫星的场景，可以应用于多个卫星。为了便于描述，图6仅以两个卫星为例进行示意，并不对本申请实施例构成限定。
具体的，该波束干扰管理方法包括：
S601：第二卫星向第一卫星发送波束开关信息。
示例性的，第一卫星为服务卫星，第二卫星为邻卫星。
需要说明的是，第二卫星向第一卫星发送波束开关信息之前需要确定卫星的覆盖区域，例如，利用所有卫星的位置信息确定各个卫星的Voronoi图。
第一卫星根据第二卫星的波束开关信息进行Voronoi图(也就是卫星的覆盖区域)的调整，例如，第二卫星根据自身的负载能力进行Voronoi图的扩张或收缩，并将扩张或收缩后的Voronoi图端点位置或偏移值作为波束开关信息发送给第一卫星，第一卫星重新确定Voronoi图，并判断波束中心点是否在自己的Vorinoi图内从而进行波束的开启或关闭。
其中，具体确定卫星覆盖区域的实现方式可以参考前述波束开关方法的描述，在此不再赘述。
可选的，也可以是第一卫星根据自身的负载能力进行Voronoi图扩张和收缩，并将扩张或收缩后的Voronoi图端点位置或偏移值作为波束开关信息发送给其他卫星。
S602：第一卫星向终端设备发送第一偏移量和波束的基准域信息。
S603：终端设备根据第一偏移量和波束基准域信息更新波束的域信息。
其中，步骤S602和S603的具体实现方式可以参考前述实施例，在此不再赘述。
需要说明的是，当卫星没有根据自身负载能力对已经确定的覆盖范围进行调整时，直接根据已经确定的覆盖范围进行波束开启或关闭，在这种情况下可以省略步骤S601。
上述实施例可以适用于卫星从低纬度运动到高纬度区域或者卫星数量多而密集的场景，在减少星间干扰的同时可以保障卫星波束范围的全覆盖，还可以对波束颜色信息进行复用， 在波束颜色信息复用的过程中进一步节省信令开销，并且颜色信息的复用减少了波束之间的干扰，实现高效的波束干扰管理。
本申请提供一种卫星网络干扰管理的实现方法，在该方法中可以应用本申请提供的波束信息指示方法和/或波束开关方法。具体的，卫星网络干扰管理的实现方法包括：
如图7A所示，对于网络侧，以卫星为例，可以包括以下步骤：
步骤1：卫星周期性的监测干扰状态或按照自身的需求进行干扰状态监测；
步骤2：卫星进行干扰状态监测后，如果干扰达到预先设定的门限值，则根据干扰情况调整和更新波束颜色复用方案和/或开关波束，并将更新的波束颜色复用方案和/或开关波束信息进行下发；如果干扰在预先设定的门限值的范围内，则卫星维持当前的波束颜色复用方案和/或开关波束的状态。
基于上述实施例，卫星根据干扰状态进行波束颜色复用方案的调整，利用本申请提供的波束信息指示方法实现波束颜色复用方案的更新，例如，重新下发更新后的基准颜色复用信息和第一偏移量或重新下发第一偏移量等，在实现波束干扰管理的同时还可以进一步节省信令开销。可选的，还可以进一步结合波束开关方法来减少星间干扰，在保障卫星波束全覆盖的情况下实现更充分的波束干扰管理。
如图7B所示，对应终端侧，可以包括以下步骤：
步骤1：终端设备周期性的从卫星接收消息，或按照自身的需求，如在预设时间范围内未收到波束基准颜色信息或波束基准颜色信息有误，导致波束干扰较大等，终端设备向卫星发送请求基准颜色信息的消息，相应的，终端设备接收卫星发送的消息。示例性的，该消息为SIB消息。
步骤2：终端设备根据卫星发送的消息判断颜色复用方案是否改变，如果颜色复用方案发生改变，则终端设备根据改变后的颜色复用方案进行更新；如果颜色复用方案未发生改变，则终端设备维持当前的颜色复用方案，不进行更新。
基于上述实施例，终端设备根据卫星下发的消息判断和更新颜色复用信息，实现颜色复用信息与卫星侧信息一致，实现波束干扰管理。
