具体实施方式
下文中将结合附图对本申请的实施例进行说明。
在附图的流程图示出的步骤可以在诸如一组计算机可执行指令的计算机系统中执行。并且，虽然在流程图中示出了逻辑顺序，但是在一些情况下，可以以不同于此处的顺序执行所示出或描述的步骤。
本申请的技术方案可以应用于各种通信系统，例如：全球移动通讯系统(Global System of Mobile communication，GSM)、码分多址(Code Division Multiple Access，CDMA)系统、宽带码分多址(Wideband Code Division Multiple Access，WCDMA)系统、通用分组无线业务(General Packet Radio Service，GPRS)、长期演进(Long Term Evolution，LTE)系统、LIE-A(Advanced long term evolution，先进的长期演进)系统、通用移动通信系统(Universal Mobile Telecommunication System，UMTS)、以及第五代移动通信技术(5th Generation wireless systems，5G)系统等，本申请实施例并不限定。在本申请中以5G系统为例进行说明。
本申请实施例中，基站可以是能和用户终端进行通信的设备。基站可以是任意一种具有无线收发功能的设备。包括但不限于：基站NodeB、演进型基站eNodeB、5G通信系统中的基站、未来通信系统中的基站、WiFi系统中的接入节点、无线中继节点、无线回传节点等。基站还可以是云无线接入网络(Cloud Radio Access Network，CRAN)场景下的无线控制器；基站还可以是小站，传输节点(Transmission Reference Point，TRP)等，本申请实施例并不限定。在本申请中以5G基站为例进行说明。
本申请实施例中，用户终端是一种具有无线收发功能的设备可以部署在陆地上，包括室内或室外、手持、穿戴或车载；也可以部署在水面上(如轮船等)；还可以部署在空中(例如飞机、气球和卫星上等)。所述用户终端可以是手机(mobile phone)、平板电脑(Pad)、带无线收发功能的电脑、虚拟现实(Virtual Reality，VR)终端、增强现实(Augmented Reality，AR)终端、工业控制(industrial control)中的无线终端、无人驾驶(self driving)中的无线终端、远程医疗(remote medical)中的无线终端、智能电网(smart grid)中的无线终端、运输安全(transportation safety)中的无线终端、智慧城市(smart city)中的无线终端、智慧家庭(smart home)中的无线终端等等。本申请的实施例对应用场景不做限定。用户终端有时也可以称为终端、接入终端、用户设备(User Equipment，UE)单元、UE站、移动站、移动台、远方站、远程终端、移动设备、UE终端、无线通信设备、UE代理或UE装置等。本申请实施例并不限定。
NTN是5G和6G网络的重要组成部分，其目的是解决偏远地区、海洋、孤岛的网络覆盖问题。NTN以卫星或高空平台(High Altitude Platform Station，HAPS)作为基站的载体，具有覆盖范围大，抗自然灾害能力强的优点。第三代 合作伙伴计划(3rd Generation Partnership Project，3GPP)正计划使用NTN网络来支持NB-IoT业务，基本思路是以NB-IoT标准为基础，分析将其应用于NTN网络可能存在的问题，然后对相关方面进行针对性增强。NB-IoT所基于的LTE网络架构和NTN网络架构不一致，如图1所示，LTE采用传统的小区覆盖模式，而NTN采用单小区多波束的覆盖模式，波束之间频率复用。
这种覆盖模式的差异将会导致一系列的问题。在地面NB-IoT网络中，UE只要识别出小区的ID就可以利用该小区ID信息和新无线(New Radio，NR)基站(Base Station，BS)之间建立有效的连接。而在NTN网络中，一颗卫星通常就是一个小区，卫星利用多个波束实现对小区的无缝覆盖。在这种情况下UE不仅要识别小区的ID信息，还要识别出信道条件最好的波束ID信息。
识别波束ID信息，首先在于UE和卫星之间要通过此波束建立通信链路，该UE的上下行数据都要依靠此波束进行发送和接收。其次，考虑到移动性，波束ID信息还是UE波束切换过程中一系列信令交互的重要依赖。此外，在NTN覆盖模式下，相同频率的波束之间存在干扰，在NB-IoT标准中，所有的干扰抑制和规避方案都是小区级的，例如物理广播信道(Physical Broadcast CHannel，PBCH)的加扰，参考信号的映射等等。对于NTN网络，在一些信道的加扰或资源映射的过程中引入波束ID信息能够有效抑制波束之间的干扰。
本申请实施例提供如下技术方案。

S12、将所述第一波束ID信息承载在第一资源上发送至第二节点。
S13、将所述第二波束ID信息承载在第二资源上发送至第二节点。

所述第一资源和第二资源可以理解为第一节点和第二节点之间的信道和/或信令。所述第一资源和第二资源可以是相同的，也可以是不同的。如果第一资源和第二资源相同，则第一波束ID信息在第一资源上的承载方式与第二波束ID信息在第二资源上的承载方式不同。
