An Overview of Key Technologies for Intelligent Access Toward 6G Full-domain Convergence
Considering the integrated air-to-ground access network,based on summarizing the relevant research,the key technologies of future air-to-ground integrated access architecture are elaborated,and the research progress in several key directions,such as air-port technology,multiple-access technology,interference analysis,computation technology,and Artificial Intelligence(AI)technology are analyzed,and a flexible network architecture with the coexistence of multiple access forms is proposed.Considering the key research problems of the access architecture in the current air-to-ground integrated network,an integrated AI-enabled architecture is constructed by combining the user's quality of service demand,and the large-scale hybrid multiple access and flexible resource adaptation strategy is proposed.Based on the future key research directions of network architecture stereoscopic,network cooperative transmission,integrated network resource management,future air-to-ground access technology,and network cooperative computation are discussed and outlooked.
