5G预商用部署策略的探讨

Discussion on 5G Pre-Commercial Deployment Strategy

5G无线技术主要标准已确定,设备产品均已成熟,5G商用频谱已划分,5G商用牌照近日也已正式发布,我国正式进入了5G商用元年。三大运营商目前正在全国主要大城市开展5G预商用的工程建设。阐述5G预商用过程中网络的网络架构,论述了无线网、承载网和核心网的改造策略和方法,重点就SA/NSA选取、CU/DU部署、频率重耕方案、站间距选择等重大部署策略进行了深入的探讨,为5G工程建设和网络部署提供了理论和实践方针。

The main standards of 5G wireless technologies have been determined,the equipment products have matured,the 5G commercial spectrum has been divided,and the 5G commercial licenses has been officially issued recently.China has officially entered the first year of 5G commercial.The three major operators are currently carrying out 5G pre-commercial engineering construction in major cities across the country.The network architecture in the 5G pre-commercial process is expounded,and the transformation strategies and methods of wireless network,the bearer network and the core network discussed.At the same time,the key deployment strategies,such as SA/NSA selection,CU/DU deployment,frequency re-cultivation scheme and station spacing selection,are discussed in depth,in order to provide theoretical and practical guidelines for 5G project construction and network deployment.
