5G移动通信网络关键技术及分析

Key technology and analysis of 5G mobile communication network

近年来,随着无线网络通信技术的不断发展,第四代移动通信系统(4G)的技术已经逐渐成熟,因此,各个国家也开始着眼于第五代移动通信技术(5G)的研究与开发。我国目前在5G技术方面的研究重点就是如何将现行的技术和未来潜在的新技术实现融合与发展。解释并介绍了5G目前的概念以及性能,研究了5G移动通信网络的关键技术,主要有大规模MIMO技术、毫米波通信技术以及D2D通信技术等。同时,也对国内外有关于5G技术的研究现状进行了探索,最后分析了5G移动通信网络的发展趋势以及面临的问题与挑战,为今后5G通信网络的正式推出做好相应的准备。

In recent years,with the development of the wireless network communication technical,the fourth generation mobile communication system（ 4G） technical has gradually flourished. Therefore,all the countries began to focus on the researchment and development of the fifth generation mobile communication technical（ 5G）. At present in our country,the most important research point on 5G technical is how to integrate and develope the existing technical and the future potential of the new technical. This paper explains the concept and performance of 5G. It analyse the key technical of 5G mobile communication network,such as large scale MIMO technical,millimeter wave communication technical and D2 D communication technical. Also,this paper have analysed both home and abroad 5g technical status. Finally we analyse the problems and challenges that 5g mobile communication network need to solve,and this a corresponding preparations for future 5g communication network officially launched.
