摘要
With the large-scale commercialization of 5G network,the research on the sixth generation(6G)network has been started.Towards 2030 and beyond,new services and new scenarios such as holographic interaction,emotional transmission,and air-space-earth integration will bring higher requirements to mobile communications,which will surely stimulate the networks evolution.ICDT converged development also provides a new paradigm for the 6G network.6G will promote the society to move towards a“digital twin”world which combines both the virtual and the physical domains,and realize the goal of“6G will rebuild a new world”through ubiquitous intelligence.New radio technologies and architecture become the key enabler to build such efficient,cooperative and intelligent 6G network.
