Abstract

Low earth orbit (LEO) satellite constellations are evolving to support on-board processing

reconfigurable functions

satellite-terrestrial cooperation

and the coordinated execution of multiple tasks

including communication

sensing

navigation

and control. However

LEO satellite networks are constrained by bottlenecks such as inadequate signal processing and computing capabilities of individual LEO satellites and constrained inter-satellite link capacity

necessitating a deep integration with terrestrial mobile communication networks that include extensive cloud-based processing and computing capabilities. Therefore

an innovative architecture for an integrated satellite-terrestrial-based 6G cloud-fog collaborative self-organizing network was proposed and its protocols were discussed

achieving the deep integration of LEO fog-based satellite networks and terrestrial cloud-based communication networks. In addition

key technologies such as integrated communication

sensing

navigation

and control waveform

as well as resource management based on satellite onboard fog processing

along with mobility management and intelligent information processing based on cloud-fog collaboration

were elaborated in detail. In the end

insights into future directions for standardization and hardware experimentation were presented.
