摘要

构建空天地海一体化网络是6G的愿景之一，也是实现“万物智联”的重要手段。卫星通信具备全球覆盖、广域连接能力，是未来空天地海一体化网络的关键要素。首先，讨论空天地海一体化网络的基本架构和发展现状，介绍面向空天地海一体化网络的卫星通信技术；然后，分析空天地海一体化网络场景下卫星通信的若干关键技术，包括体系架构、空中接口、资源调度、网络切片和组网管理等技术；最后，讨论空天地海一体化发展趋势下，卫星通信面临的挑战及其发展前景。

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.
