摘要

本文首先概述了3GPP Release-17中正在开发的5G新无线电(NR)组播和广播服务(MBS)。支持基于Rel-17 5G NR网络的多播和广播业务，能够将多媒体流或下载业务传输到各种类型的通用5G设备。根据第17版5G新空口MBS的原理，中国广播网络(CBN)与行业合作伙伴合作，利用商用5G新空口网络平台和支持5G的智能手机，开发了全球首个5G新空口MBS端到端原型试验系统。在原型系统的基础上，分别对移动接收和固定接收进行了蜂窝部署和高塔部署的现场试验测试。现场测试结果表明，5G NR组播和广播技术具有通用性、灵活性和高效性，能够与已部署的移动通信网络高度融合，代表了未来新广播/组播技术的发展方向。

Field Test for 5G NR Multicast and Broadcast Services

This paper first provides an overview of 5G new radio (NR) multicast and broadcast service (MBS), which is under development in 3GPP Release-17. Multicast and broadcast services based on Rel-17 5G NR network are supported and capable of transporting multimedia streaming or download services to various types of general-purpose 5G-capable devices. Following the principle of Release-17 5G NR MBS, China Broadcasting Network (CBN) cooperated with industry partners to develop the world's first 5G NR MBS end-to-end prototype trial system using commercially-available 5G NR network platform and 5G-capable smartphones. Based on the prototype system, field trial tests for cellular deployment and high-tower deployment are conducted for mobile and fixed receptions respectively. The field test results demonstrate the versatility, flexibility and efficiency of 5G NR multicast and broadcast technology, which can be heavily integrated with the deployed mobile communication network, and represents the evolution direction of new broadcast/multicast technology in the future.
