Towards 6G Wireless Communication Networks: Vision, Enabling

Technologies, and New Paradigm Shifts

Fifth generation (5G) wireless satisfy the requirement of global coverage, (THz), and optical frequency bands. Third,

these requirements, 6G networks will rely
on new enabling technologies, i.e., air

and novel network architecture, such
as waveform design, multiple access,
channel coding schemes, multi-antenna
technologies, network slicing, cell-

computing. A long-form review, titled
"Towards 6G wireless communication
networks: vision, enabling technologies,
and new paradigm shifts," was published
in SCIENCE CHINA Information Sciences.
It is co-authored by Prof. Xiaohu You

Chengxiang Wang (corresponding author)
from Southeast University, China, along
with other 48 experts and scholars from
scientific research institutes, colleges, and
companies both at home and abroad. In
this article, the vision on 6G is that it will
have four new paradigm shifts. First, to
