Overview and Prospect of 5G Broadcast Technology Development Research
[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.
