摘要

首先简要回顾5G和低轨卫星通信的发展历程，并从需求、应用、技术等多个维度进行分析判断，指出低轨卫星通信在5G时代的定位是：与5G互补，而不是颠覆5G。进而在分析我国发展低轨卫星通信的应用需求、技术与产业基础等因素的基础上，提出了我国发展低轨卫星通信的建议：“与5G兼容，到6G融合”，分两个发展阶段。第一阶段，当前发展以5G技术为基础进行针对性修改和优化的低轨卫星通信系统，与5G兼容，最大程度复用5G技术，并利用5G规模经济，降低成本，实现差异化竞争优势；第二阶段，到6G时，实现陆地移动通信和高中低轨卫星通信的有机融合。最后提出建议：两个争取和两个合作，即鼓励申请和争取频谱资源和轨道资源，推进国际合作与国内合作，加速产业成熟，实现商用成功。

Abstract

The review on the development in 5G and LEO satellite communications was given on multi aspects.The role of LEO satellite communication in 5G was positioned as a complement

not yet as the main role.The proposals were thus given based on the analysis of the application requirements

technologies and the industrial level regarding to the LEO satellite communication R＆amp;D in China.Suggestions for the development of LEO satellite communication in China as:“compatible with 5G

integrated within 6G” were put forward.The development process could be divided into two steps.In the first step

the current LEO satellite communication system could be developed mostly based on the 5G technologies and compatibility

the maximumly reuse of 5G key technologies

the cost reduction from the scale economy effect of 5G

and finally the LEO advantages achieved from the differentiation between 5G and LEO.In the second step

the terrestrial mobile communication and the high

medium and low orbit satellite communications would be harmony integrated in 6G.The final suggestions were of two efforts and two cooperations:encouraging application and getting more frequency resources and satellite orbit resources

the international cooperation and the domestic cooperation

to accelerate the industrial maturity and to achieve commercial success.
