摘要
为满足全时、全域通信需求,低轨卫星通信将成为6G的重要组成部分。通过对地面移动通信协议体制进行适应性改进,低轨卫星可为地面移动手机终端提供直连服务。介绍了面向手机直连的低轨卫星通信关键技术和商业项目发展现状,探讨了未来需解决的关键问题和潜在技术途径。
In order to realize anytime and anywhere communication,low earth orbit(LEO)satellite communication becomes a key component in 6G.Through the adaptive enhancement of terrestrial mobile communication protocol,LEO satellites can provide direct connection services for mobile phones.The related key technologies and the recent progress of various commercial programs were introduced,and future issues were also identified together with poten-tial technical solutions.
