摘要
本文对我国未来5G广播的发展路径开展了研究。首先分析了5G广播可开展的业务形态,提出了总体发展路径。其次对“小区5G广播”和“广域5G广播”的关键技术进行了剖析,其中解读了各技术在3GPP Rel-18中的演进方向。然后从频谱规划角度分别提出了基于600MHz和700MHz频段的广域5G广播部署方案。最后提出了NR广播作为广域5G广播解决方案时亟待解决的若干问题。
This paper conducts research on the development route of 5G Broadcasting of China in the future.Firstly,it analyzes the services that 5G Broadcasting can support,and suggests an overall development route.Secondly,it analyzes the key technologies of“Cell 5G Broadcasting”and“Wide-Area 5G Broadcasting”,and interprets the evolution of these technologies in 3GPP Rel-18.Then,from the perspective of spectrum planning,Wide-Area 5G Broadcasting deployment solutions based on 600MHz and 700MHz frequency bands were respectively proposed.Finally,several issues are proposed that need to be resolved urgently when NR broadcasting is used as a solution for Wide-Area 5G Broadcasting.
