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 inte-grated network is satellite communication,which provides global coverage and wide-area connectivity.The basic ar-chitecture 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 tech-nologies of satellite communication in the space-air-ground-sea integration scenario were analyzed,including adap-tive 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.
