摘要
信息社会日益增长的需求,促使着无线通信技术的不断发展。计划于2020年进入商业运营的5C无线通信技术,尚在探索和研究阶段。从无线通信的发展历程出发,介绍了当前国内外的无线通信发展的最新趋势,然后从频谱资源紧缺、系统容量亟需提高的角度,着重介绍了两个关键的物理层技术——毫米波通信技术和大规模MIMO技术,以应对未来无线通信的发展要求。此外,还概括性地介绍了5G无线通信系统的应用场景以及未来的发展趋势。
The continuously increasing demand of wireless communications impels the fast development of the next generation wireless communication technology. The 5G communication technology, which scheduled to be commercialized in the year beyond 2020, is still on its earlier stage. Based on the development history of wireless communications, the latest trend in the development of the wireless communications at home and abroad was presented. In order to solve the shortage of spectrum resources and improve the capacity of system, two key technologies of physical layer （millimeter-wave communications and massive MIMO） were introduced and remarked. Furthermore, the scenarios and development trend of 5G mobile communication systems in the future were also described.
