5G广播技术发展研究综述与展望

Overview and Prospect of 5G Broadcast Technology Development Research

【目的】为了满足日益增长的广播电视移动公共服务、应急和公共安全服务、群组通信、物联网和车联网等业务的需求,对5G广播技术发展研究进行梳理,以便更好地建设部署可以有效支撑上述应用场景服务的5G广播系统。【方法】通过对5G广播发展的文献进行研究,并对LTE 5G广播和5G NR广播这两种技术方式的系统架构、技术特性等方面的进行探讨,提出了对5G广播发展的观点,并进行了展望。【结果】5G广播的两种技术分别承担着不同网络环境下的应用需求,存在一定区别和互补关系,短期内能在一定范围内并行共存,长期必将走向全面统一。【结论】建设5G广播需要根据自身的业务需求、技术发展趋势和产业成熟度选择合适的技术方式,发展新型广播业务,提高网络服务能力。

[Purposes]In order to meet the growing demand for broadcast and TV mobile public services,emergency and public safety services,group communications,Internet of Things(IoT)and Vehicle to Ev-erything(V2X),research on 5G broadcast technology is conducted to build and deploy 5G broadcast sys-tems that can effectively support services of the above application scenarios.[Methods]Through the lit-erature research on the development of 5G broadcast,combined with the discussion of the system archi-tecture and technical characteristics of the two technical methods,the views and prospects of the develop-ment of 5G broadcast were put forward.[Findings]The two technologies of 5G broadcasting bear differ-ent application requirements under different network environments,and there are certain differences and complementary relationships.In the short term,5G broadcast technology will coexist in parallel within a certain range,and in the long term,it will certainly move towards full unification.[Conclusions]The con-struction of 5G broadcast needs to choose the right technical route according to its own business needs,technology development trends and industrial maturity,develop new broadcast services,and improve net-work service capabilities.
