Abstract

Abstract: With analysis of the integration of the satellite communications and the 5G system, the necessity of the integrated design of the radio air-interface technologies was pointed out firstly. Then, based on the research of NTN in 3GPP, key technologies of the radio air-interface for the integrated satellite-terrestrial system were refined, and potential solutions were proposed. Finally, for the future development of satellite-terrestrial integration, the unified radio airinterface design idea based on variable parameter set was discussed, which will provide guidance for future NTN projects in 3GPP standardization.

Key words: 5G technology, satellite communication, integration of the satellite communication and 5G, radio airinterface
