Study on the key technologies of satellite communication for space-air-ground-sea integration
Abstract
Building a space-air-ground-sea integrated network is one of the visions of 6G, and it is also an important means to realize the “intelligent connection of all things”. The key element of the future space-air-ground-sea integrated network is satellite communication, which provides global coverage and wide-area connectivity. The basic architecture and development status of the space-air-ground-sea integrated network were discussed, and the satellite communication technology for the space-air-ground-sea integrated network was introduced. Then, several key technologies of satellite communication in the space-air-ground-sea integration scenario were analyzed, including adaptive air interface, multi-satellite cooperative robust beamforming, multi-dimensional resource on-demand scheduling, networking/network management, and network slicing technology. Finally, the challenges and application prospects of satellite communication were discussed under the development trend of space-air-ground-sea integration in the future.
