5G授权频谱分配及非授权频谱利用技术的研究

随着移动互联网和移动终端的不断发展，移动数据流量也大幅度增长。因此，在第五代蜂窝移动通信系统中，如何对现有的频谱资源进行有效的分配和利用成为了讨论和研究的热点。一方面，5G系统的频段向高频方向拓展，增大可用的频谱资源。另一方面，5G系统继续对接入技术进行演进，以实现对非授权频谱资源的充分利用。本文的内容主要分为三部分，分别对目前主流阵营的授权频谱分配计划、正处于讨论中的非授权频谱接入技术和目前的标准化进程进行了介绍。

The study on spectrum allocation and access technology in unlicensed spectrum of 5G

With the development of mobile internet and mobile terminals, the data traffic has experienced a significance increment. Thus, efficient allocation and utilization of spectrum resources become heat topics to the fifth generation telecommunication system. In one hand, the spectrum of 5G extends to high-band, increasing the usable spectrum resources. In the other hand, the access technologies continue to develop in 5G, hoping to realize the fully utilization of unlicensed spectrum. This passage has two main parts, separately giving introductions to the spectrum allocation of main camps and access technologies of unlicensed spectrum which are still under discussion and the standardization process nowadays.
