摘要

第三代合作伙伴计划(3GPP) Rel-14/16(也称为“5g广播”)的广播/多播配置文件中引入的新功能代表了一个非常有希望的机会，可以通过网络运营商和内容提供商之间的密切协同作用，更有效地利用网络和频谱资源，同时覆盖更广泛的受众。目前，内容提供商和广播运营商正在积极参与多个研究项目，旨在分析5G在多大程度上可以用于向移动/便携式设备大规模传输电视信号。在这方面，本文旨在通过实验室测试、覆盖模拟分析和现场试验，概述5g广播技术的潜力，并特别关注一些可能对媒体链中所有相关参与者具有吸引力的部署模式。具体而言，意大利广播电视台(RAI)-研究、技术创新和实验中心(CRITS)成功测试了覆盖都灵大都市区的5g广播技术，并在奥斯塔山谷使用单频网络。

5G-Broadcast: Laboratory Tests and Field Trials for the Mobile TV of Tomorrow

The new features introduced in the broadcast/multicast profile of 3rd Generation Partnership Project (3GPP) Rel-14/16, also known as “5G-broadcast,” represent a very promising opportunity to address the challenges of the media sector allowing, by means of a close synergy between network operators and content providers, more efficient use of both network and spectrum resources while reaching wider audiences. At present, content providers and broadcast operators are actively involved in several research projects aiming to analyze to what extent 5G can be used for large-scale transmission of TV signals to mobile/portable devices. In this respect, this article aims at providing a general overview of the potential of 5G-broadcast technologies by means of laboratory tests, coverage simulation analysis, and field trials, with a particular eye on some deployment models that could be attractive for all the involved players in the media chain. Specifically, Radiotelevisione Italiana (RAI)-Centre for Research, Technology Innovation and Experimentation (CRITS) successfully tested 5G-broadcast technology with the coverage of the metropolitan area of Turin, and in the Aosta Valley with a single-frequency network.
