Abstract:

6G technology is still in its initial stage of research.It is expected that in the next few years,the world will gradually reach a consensus on visions and key technical parameters of 6G .Focusing on the further expansion of application areas and further enhancement of technical capability,the technical fields were summarized that may be involved in the future 6G radio access,including the coverage expansion based on the satellite-terrestrial integration,millimeter wave and terahertz communications,data-driven network artificial intelligence (AI) and security,large-scale cooperation and cell-free architecture innovation,etc.On this basis,some important technologies,such as ultra-high reliability and low latency,full dynamic radio resource allocation and centimeter level precise positioning,which need to be further broken through in the wide-area Internet of things (IoT) based on the public mobile communication system were analyzed and prospected.Finally,the conclusions were given.

Key words: 6G mobile communication, wide-area IoT, satellite-terrestrial converged communication, millimeter wave and terahertz, AI communication
