Zhang Ping, academician of the Chinese Academy of Engineering: 6G faces dimensional disaster

5G is developing in full swing. Currently, the number of 5G users in China has exceeded 100 million, and there are more than 480,000 5G base stations across the country.

At the same time, 6G network technology has also been put on the agenda. Companies such as Huawei and ZTE have begun to deploy 6G research and development. Developed countries such as Japan, South Korea, Finland and the United States are also actively developing 6G networks.

Zhang Ping, an academician of the Chinese Academy of Engineering and a professor at Beijing University of Posts and Telecommunications, pointed out that the driving force behind the evolution of mobile communications will shift from the single rate requirement of the 1G/2G/3G/4G era to scenario-driven as the basic evolution paradigm through the transition of three 5G scenarios.

Zhang Ping believes that in the process of evolution to 6G, the traditional technology route of following the stacking processing mode and taking complexity in exchange for performance gain is no longer sustainable, and new theoretical innovation is urgently needed. "6G must not only increase the speed and expand the space, but also improve the wisdom and study the new system of the relationship between intelligence, communication and the future of mankind."

From 1G wireless communication which only needed to increase frequency and reduce modulation, to 3G/4G which had more and more stacked development which led to an increasing burden on the network. After the arrival of 6G, intelligence and ubiquity have become one of the important requirements of mobile communications, which is divided into three parts with the demand for high speed. The traditional Shannon information theory can no longer meet the development needs.

Zhang Ping introduced that in the 6G system, people and network nodes can conduct deeper information interaction through semantic interaction, allowing humans to move from "outside the network" to "inside the network", and people and network nodes can become one and evolve together.

The 6G system is an open system in a non-equilibrium state, which is constantly evolving in the mutual transformation between "disorder" and "order". Its design goal is to reduce the disorder of the system and guide the system to evolve towards an ordered structure.
