Research on key technologies for direct-to-cell communication networking
摘要
Abstract
With the advancement of 5G Non-Terrestrial Network(NTN)standardization and the emergence of the 6G vision of ubiquitous,all-time,and all-domain connectivity,direct-to-cell satellite communication has become a promising approach for building integrated space-ground networks in the 6G era.This technology not only enables ubiquitous global access for mobile users but also supports reliable,high-speed communication services across diverse geographical and temporal scenarios.This paper reviews the evolution and future development trends of direct-to-cell satellite communication standards,focusing on the 3GPP NTN framework.It further analyzes the transition of network architectures from satellite transparent relay systems to architectures in which base station functionalities are deployed onboard satellites.Particular attention is given to the challenges and future research directions associated with key networking technologies,including radio access,link adaptation,and resource management in direct-to-cell satellite communication systems.Finally,the paper summarizes the current state of research and outlines potential future directions for the development of direct-to-cell satellite communication networks.关键词
