蜂窝结构与5G无线通信网络关键技术分析

Cellular Structure and Key Technology Analysis of 5G Wireless Communication Network

在5G技术引领移动互联网无线连接的背景下,以5G系统的蜂窝结构作为切入点进行5G资源利用价值的深入分析,在此基础上引入毫米波、大规模MIMO传输、移动基站以及新空口4项关键技术进行应用要点的梳理。从上下行解耦、选用双连接方式、利用优质低频资源3个方面探讨关于加快5G通信网络建设、提升通信传输质量的具体路径,以期为5G网络应用落地提供参考。

Under the background of 5G technology leading the wireless connection of mobile Internet,the cellular structure of the 5G system is used as an entry point to conduct an in-depth analysis of the value of 5G resource utilization,and on this basis,four items:millimeter wave,massive MIMO transmission,mobile base station and new air interface are introduced.The key technologies are used to sort out the application points.Discuss specific paths for accelerating the construction of 5G communication networks and improving the quality of communication transmission from three aspects:decoupling of uplink and downlink,selection of dual connection methods,and utilization of highquality low-frequency resources,in order to provide a reference for the implementation of 5G network applications.
