With the rapid development of wireless technologies, the concept of the Fifth Generation (5G) wireless communication system started to emerge. But most people know little about 5G，including some aspects of 5G wireless communication networks ,just like what 5G is about: what are the building blocks of core 5G system concept, what are the main challenges and how to tackle them. Besides, A number of countries and organizations working on 5G, 5G development situation in China is of concern to everyone, China also needs to have its own place in such a competitive environment.
随着无线技术的飞速发展，第五代(5G)无线通信系统的概念开始出现。但大多数人对5G知之甚少,包括5G无线通信网络的某些方面,就像5G是什么:什么是核心5G系统的构建块的概念,主要的挑战是什么,以及如何解决这些问题。此外，一些国家和组织致力于5G, 5G在中国的发展情况是每个人都关心的，中国也需要在这样的竞争环境中有自己的位置。
