Abstract

Abstract

With the commercialization of 5G mobile communication networks, researches on the development vision, capability requirements and key technologies of the new generation mobile communication systems (6G) are becoming new hotspots. Firstly, the key technical fields are summarized that may be involved in the future 6G communication, including the deep satellite-terrestrial integration, the new spectrum communication, the distributed cooperative MIMO and intelligent communication. The Space-Ground Integration Network (SGIN) based on the deep satellite-terrestrial integration is discussed further. Secondly, for the two possible network topologies, the characteristics and technical requirements of the interstellar high-speed link, the satellite-terrestrial feeder links and the user links are analyzed. The progress of high-speed communication applied to three different types of transmission links is summarized. In the end, the key technologies which are urgently needed to break through in the SGIN are analyzed and prospected, such as the multiple-access based on optical phased array, the high-efficiency satellite-terrestrial laser communication and the optoelectronic hybrid networking, and the directions are pointed out for the subsequent related researches.
