摘要
日益增长的数据流量以及智能终端的普及,导致第四代移动通信网络(4G)在容量、速率、频谱等方面已经不能满足人们对网络的需求。基于此,第五代移动通信网络(5G)应运而生。在回顾移动通信近年来的发展历程的基础上,从网络部署场景、接入网、核心网三大块,总结出一种5G的网络架构,该架构具有大容量、高速率、低时延的特点。基于此架构,描述了5G的四大潜在关键技术:超密集异构部署、D2D(device-to-device)通信、大规模MIMO(multiple input multiple output)、绿色通信,同时叙述了未来研究存在的挑战。
The increasing growth of data traffic and the popularity of the intelligent terminals lead to the fact that the fourth generation mobile communication network （4G） cannot meet the demand in terms of capacity, speed, and the spectrum. Thereby the fifth generation mobile communication network （5 G） comes into being. Based on reviewing the development of mobile communications in recent years in this article, a type of 5G network architecture is summarized from network deployment scenarios, access network, core network, which has a large capacity, high-speed, low-latency characteristics. Based on the architecture, four potential key technologies are described, Super dense heterogeneous deployment, D2D telecommunication, Massive MIMO and Green communications, meanwhile the future research challenges are also presented.
