具体实施方式
下面详细描述本申请的实施例,实施例的示例在附图中示出,其中自始至终相同或类似的标号表示相同或类似的元件或具有相同或类似功能的元件。下面通过参考附图描述的实施例是示例性的,仅用于解释本申请,而不能解释为对本发明的限制。

为使本申请的目的、技术方案和优点更加清楚,下面将结合附图对本申请实施方式作进一步地详细描述。
本申请实施例提供的技术方案可以适用于多种系统,尤其是5G系统。例如适用的系统可以是全球移动通讯(global system of mobile communication,GSM)系统、码分多址(code division multiple access,CDMA)系统、宽带码分多址(Wideband Code Division Multiple Access,WCDMA)通用分组无线业务(general packet radio service,GPRS)系统、长期演进(long term evolution,LTE)系统、LTE频分双工(frequency division duplex,FDD)系统、LTE时分双工(time division duplex,TDD)系统、高级长期演进(long term evolution advanced,LTE-A)系统、通用移动系统(universal mobile telecommunication system,UMTS)、全球互联微波接入(worldwide interoperability for microwave access,WiMAX)系统、5G新空口(New Radio,NR)系统等。这多种系统中均包括终端设备和网络侧设备。系统中还可以包括核心网部分,例如演进的分组系统(Evloved Packet System,EPS)、5G系统(5GS)等。
首先对本申请涉及的一些名词进行介绍和解释:
本申请实施例涉及的终端设备,可以是指向用户提供语音和/或数据连通性的设备,具有无线连接功能的手持式设备、或连接到无线调制解调器的其他处理设备等。在不同的系统中,终端设备的名称可能也不相同,例如在5G系统中,终端设备可以称为用户设备(User Equipment,UE)。 无线终端设备可以经无线接入网(Radio Access Network,RAN)与一个或多个核心网(Core Network,CN)进行通信,无线终端设备可以是移动终端设备,如移动电话(或称为“蜂窝”电话)和具有移动终端设备的计算机,例如,可以是便携式、袖珍式、手持式、计算机内置的或者车载的移动装置,它们与无线接入网交换语言和/或数据。例如,个人通信业务(Personal Communication Service,PCS)电话、无绳电话、会话发起协议(Session Initiated Protocol,SIP)话机、无线本地环路(Wireless Local Loop,WLL)站、个人数字助理(Personal Digital Assistant,PDA)等设备。无线终端设备也可以称为系统、订户单元(subscriber unit)、订户站(subscriber station),移动站(mobile station)、移动台(mobile)、远程站(remote station)、接入点(access point)、远程终端设备(remote terminal)、接入终端设备(access terminal)、用户终端设备(user terminal)、用户代理(user agent)、用户装置(user device),本申请实施例中并不限定。
本申请实施例涉及的网络侧设备,可以是基站,该基站可以包括多个为终端提供服务的小区。根据具体应用场合不同,基站又可以称为接入点,或者可以是接入网中在空中接口上通过一个或多个扇区与无线终端设备通信的设备,或者其它名称。网络侧设备可用于将收到的空中帧与网际协议(Internet Protocol,IP)分组进行相互更换,作为无线终端设备与接入网的其余部分之间的路由器,其中接入网的其余部分可包括网际协议(IP)通信网络。网络侧设备还可协调对空中接口的属性管理。
例如,本申请实施例涉及的网络侧设备可以是全球移动通信系统(Global System for Mobile communications,GSM)或码分多址接入(Code Division Multiple Access,CDMA)中的网络侧设备(Base Transceiver Station,BTS),也可以是带宽码分多址接入(Wide-band Code Division Multiple Access,WCDMA)中的网络侧设备(NodeB),还可以是长期演进(long term evolution,LTE)系统中的演进型网络侧设备(evolutional Node B,eNB或e-NodeB)、5G网络架构(next generation system)中的5G基站(gNB),也可以是家庭演进基站(Home evolved Node B,HeNB)、 中继节点(relay node)、家庭基站(femto)、微微基站(pico)等,本申请实施例中并不限定。在一些网络结构中,网络侧设备可以包括集中单元(centralized unit,CU)节点和分布单元(distributed unit,DU)节点,集中单元和分布单元也可以地理上分开布置。
网络侧设备与终端设备之间可以各自使用一或多根天线进行多输入多输出(Multi Input Multi Output,MIMO)传输,MIMO传输可以是单用户MIMO(Single User MIMO,SU-MIMO)或多用户MIMO(Multiple User MIMO,MU-MIMO)。根据根天线组合的形态和数量,MIMO传输可以是2D-MIMO、3D-MIMO、FD-MIMO或massive-MIMO,也可以是分集传输或预编码传输或波束赋形传输等。
卫星通信系统中,区分两类波束,即第一类波束和第二类波束,第一类波束也可称为随遇波束,第二类波束也可称为业务波束,其中,第一类波束不为连接态UE提供服务,第二类波束可允许UE接入,为连接态UE提供服务。一个卫星的通信覆盖范围可以划分为多个波位,其中第一类波束通过周期性扫描每个波位实现为每个波位提供服务的目的,每个周期内第一类波束在每个波位服务固定单位时间,例如5ms,处于每个波位的UE可以周期性获得第一类波束的服务。第一类波束工作带宽较窄,不为连接态UE提供服务,第一类波束可以为UE广播系统信息。每个第一类波束可以通过对应的波束标识区分识别。
卫星系统通过第二类波束为连接态UE提供服务。一个卫星可以支持多个第二类波束,每个第二类波束的工作频域以及带宽等可以不同。第二类波束与第一类波束的工作频域和带宽也不同,第二类波束按需调度,即根据是否某波位有UE需要接入服务,而调度第二类波束为该UE服务。
由于为连接态和非连接态UE服务的波束类型不同,UE如何通过第一类波束获知可以接入的第二类波束有待解决。
因此,本申请实施例中提供的获取波束信息的方法,UE通过第一类波束系统信息中广播的当前覆盖波位的第二类波束的相关信息,获取可以接入的第二类波束的信息,和/或,UE通过第一类波束发送接入请求,第一类波束通过系统信息或者媒体接入控制层控制单元(Media Access  Control Control Element,MAC CE)携带为该UE提供服务的第二类波束的相关信息。
下面以具体地实施例对本申请的技术方案以及本申请的技术方案如何解决上述技术问题进行详细说明。下面这几个具体的实施例可以相互结合,对于相同或相似的概念或过程可能在某些实施例中不再赘述。下面将结合附图,对本申请的实施例进行描述。

下面结合附图3至图9,并以“预设卫星系统划分500个波位,第一类波束在每个波位驻留时间为5ms,则第一类波束扫描周期为2.5s,第一类波束的波束index(标识)为0-499,第二类波束的标识为1-5”为例,对本申请实施例提供的一种获取波束信息的方法的具体实现过程进行详细的描述。
实施例1:通过发送接入请求来获取第二类波束信息。
实施例1-1:UE通过MAC CE方式获得第二类波束信息的方法如图3所示,包括:
步骤301:UE驻留在第一类波束,预设该第一类波束的标识为15,并在该第一类波束发起接入请求。
具体的,在该实施例中,在发送接入请求前,UE在该第一类波束15获得系统信息,其中,系统信息包含5个第二类波束的基本信息或至少一个第二类波束的基本信息(即:系统信息中可以包含所有第二类波束的基本信息,或者可能调度到该波位的第二类波束的基本信息)。每个第二类波束的基本信息包括以下至少一项:
