摘要
第5代移动通信系统(5G)是面向2020年之后的新一代移动通信系统,其技术发展尚处于探索阶段.结合国内外移动通信发展的最新趋势,本文对5G移动通信发展的基本需求、技术特点与可能发展途径进行了展望,并分无线传输和无线网络两个部分,重点论述了富有发展前景的7项5G移动通信关键技术,包括大规模天线阵列、基于滤波器组的多载波技术、全双工复用、超密集网络、自组织网络、软件定义网络及内容分发网络.本文还概括性地介绍了国内5G移动通信的相关研发活动及其近期发展目标.
5G is a new generation mobile communication system that is to be commercialized in the year beyond 2020. Currently the development of 5G mobile communication system is on its earlier stage. In this article, the development requirements, technique features and possible approaches for the 5G are firstly addressed. The wireless transmission and networking techniques are introduced and remarked, which include massive multiple-input- multiple-output （MIMO）, filter-bank based multi-carrier, full duplex, ultra dense network （UDN）, self-organizing network （SON）, software defined networking （SDN）, and content distribution network （CDN）. Futhermore, the recent R＆D and promotion activities for 5G mobile communication system in China are summarized.
