With the development of mobile communication technology in the world, within a few years, mobile communication has developed from 2G/3G to 4G technology, which has made significant achievements in practical applications and user experience and other aspects. However, with the development of communication technology, people can no longer meet the needs of 4G mobile communication. Related workers are developing a more advanced communication technology, the 5G mobile communication technology, which will become a new generation of mobile communication systems in the next decade. In this paper, some key technologies of 5G mobile communication are described in detail, and the development trend in the future is analyzed.%随着世界各国对移动通信技术发展的极大重视,在短短几年时间内,移动通信就从以往的2G/3G发展到现阶段的4G技术,在实际应用、用户体验等方面有了显著地提升.然而,随着通信技术的发展,人们已经不能满足4G移动通信所带来的体验,相关的工作者正在研发一种更高端的通信技术——5G移动通信技术.该通信技术在未来的十年后将成为新一代的移动通信系统,因此本文详细描述了5G移动通信的若干关键技术,并对未来的发展趋势进行了分析.
