5G移动通信发展趋势与若干关键技术
摘要
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 rstly 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 de ned networking (SDN), and content distribution network (CDN). Furthermore, the recent R&D and promotion activities for 5G mobile communication system in China are summarized.
