AI-Driven Seamless and Massive Access in Space-Air-Ground Integrated Networks

The global ubiquitous coverage vision of the sixth-generation (6G) mobile communication system marks a significant leap beyond its predecessors by combining terrestrial networks (TN) with non-terrestrial networks (NTN) into a unified framework known as space-air-ground integrated networks (SAGIN). With the proliferation of IoT devices and reliable connectivity demands in diverse environments, seamless and massive access has become one of the key indicators of future networks which still suffer from frequently changed network topology, limited spectrum resources, dynamic and unstable links, and constrained energy supply. Therefore, it is critical to study how to leverage the potential of artificial intelligence…
