Abstract

Abstract: With the accelerating commercialization of the 5th generation of mobile communications system(5G), the next 6th generation of mobile communications system(6G) is attracting extensive research interests from both the industry and academia. Towards the evolution from 5G to 6G, the requirements and challenges of 6G are investigated from the following four aspects:1) the enhancement of 5G key performance indicators; 2) multi-objective optimization in mixed scenarios; 3) new key performance indicators under emerging scenarios; 4) network operations requirements. Based on the analysis between 5G performance and the required conditions, potential improvements on 5G standard as well as our suggestions on the 6G key performance indicators are presented. Meanwhile, the technology trends and preliminary solutions for 6G are also proposed accordingly.

Key words: the 6th generation of mobile communications system, visions and requirements, key performance indicators
