摘要
卫星在覆盖范围、可靠性和灵活性等方面与地面5G网络具有融合互补的优势,尤其是低轨卫星和5G网络的融合已成为业界研究热点之一.重点面向星地融合领域介绍了 5G网络增强架构及融合关键技术.首先,分析了星地融合领域发展趋势并列举重点应用场景;其次,介绍了5G网络增强架构,涉及基于透明转发卫星和基于可再生卫星的两种组网架构;最后,重点围绕星地融合通信业务需求分析了相关关键技术并进行了简要总结,为5G星地融合的应用落地提供有益参考.
Abstract
Satellites have the advantages of complementing terrestrial 5G network in terms of coverage,reliability and flexibility,especially the integration of low earth orbit(LEO)satellite and the terrestrial 5G network has been one of the hot topics in the industry.The enhanced 5G network architecture and related key technologies for satellite-terrestrial integration were primarily introduced.Firstly,the development trends in the field of satellite-terrestrial inte-gration were analyzed and key application scenarios were listed.Secondly,two enhanced 5G network architectures were introduced,which involved transparent relay satellites and renewable satellites.Finally,the related key technolo-gies were analyzed for the business requirements of satellite-terrestrial integrated communication and the brief sum-mary was given,which provided useful reference for the application of 5G satellite-terrestrial integration.
