摘要
高塔高功率5G广播具备覆盖范围大、抗损毁能力强等优势,适用于应急广播场景。本文梳理了5G广播标准,着重从物理层设计比较现有技术路线,设计适用于应急广播的高塔高功率技术方案,开发原型系统并展开测试。结果表明该方案能够提供丰富灵活的应急消息内容,提供高质量的应急广播服务。
5G high power high tower broadcast has advantages of large coverage and strong resistance to damages,which is suitable for emergency broadcast services.This paper reviews the 3GPP standardization of multicast and broadcast services,and the state-of-the-art approaches are evaluated and compared from the aspect of physical layer design.A novel technical scheme was proposed and validated based on the prototype system.The result suggests this scheme can provide much richer emergency messages and high-quality emergency broadcast services.
