摘要
随着5G牌照的发放和国家"新基建"政策的引导推进,我国5G网络建设进程必将迈入快车道。相对于传统运营商而言,广电5G网络具备频段不同、制式多样、业务融合等差异化特点,决定了面向广播电视的5G网络在规划建设方面存在一定独特性,本文首先在研究回顾移动通信网络规划相关理论的基础上,针对面向广播电视的5G网络规划设计的特点、基本方法及要点进行一些探讨,然后以国内某重点城市密集城区部分区域为覆盖场景,使用700MHz+4.9GHz协同组网、上行增强技术相结合的方式进行覆盖仿真,给出在一定组网条件下目标区域基站密度及参考信号接收功率(RSRP)、信号干扰噪声比(SINR)等主要参数的仿真结果,为面向广播电视的5G网络规划设计提供参考。
With the issuance of 5 G licenses and the guidance of national"new infrastructure"policy,5 G network construction will enter fast lane.Compared with traditional network operators,radio and television 5 G network has the characteristics of different frequency bands,diversified formats and business convergence,which determine that 5 G network for radio and television has a certain uniqueness in planning and construction.Firstly,based on research and review of relevant theories of mobile communication network planning,this paper conducts some discussions on the characteristics,basic methods and main points of 5 G network planning and design for radio and television.Then,taking some dense urban areas of a key city in our country as coverage scene,the paper carries out coverage simulation by using 700 MHz+4.9 GHz cooperative networking and uplink enhancement technology.Finally,the paper gives simulation results of main parameters such as base station density,reference signal received power(RSRP)and signal to interference and noise ratio(SINR)in target area under certain networking conditions.It provides a reference for planning and design of 5 G network for radio and television.
