Abstract:

As 5G goes into commercial use, 6G has increasingly become a research hotspot by academics and industries. The integrated air-space-terrestrial communication (IASTC) is regarded as an important key technology of 6G, due to its advantages such as expanding coverage and saving cost. In this paper, the system design and key technologies of 6G IASTC are studied. Firstly, the driving force of 6G IASTC is analyzed, then the basic concept of system design is discussed, and then the difficulties and challenges are analyzed. Finally, a series of key technologies for 6G IASTC are proposed and discussed in depth. The research of this paper will provide reference for future work on 6G, including key technology research, system design, standard promotion and also industrialization.

Key words: 6G, integrated air-space-terrestrial communication (IASTC), multiple beams coordination
