摘　　要：针对当前城区已经完成5G通信网络基础覆盖,以及后期郊区和乡镇环境下5G覆盖发展,结合5G建设成本、运营成本、实际网络覆盖需求、4G/5G用户过渡多角度分析未来5G网络发展需求,推动时分双工(Time Division Duplex,TDD)和频分双工(Frequency Division Duplex,FDD)高低频组网技术下5G组网架构融合发展,进一步简化当前通信网络结构和提升网络运营效益,实现蜂窝通信技术平稳迭代。Considering the completion of the basic coverage of 5G communication network in urban areas and the later development of 5G coverage in rural areas,this paper analyzes the future 5G network development needs from multiple perspectives such as 5G construction costs,operating costs,actual network coverage requirements,and 4G/5G user transition.This paper promotes the integration and development of 5G networking architecture under the high and low frequency networking technologies of Time Division Duplex(TDD)and Frequency Division Duplex(FDD),and further simplify the current communication network structure and improve the efficiency of network operations,and finally realize the stable iteration of cellular communication technology.
