摘要
在卫星互联网技术体制的多种路线中,基于3GPP 5G非地面网络(Non-Terrestrial Networks,NTN)演进的技术体制因其适配3GPP国际标准,可以充分复用地面网络及终端的成熟产业链,同时大幅降低空间段研制部署的技术难度和成本,并且使系统具有面向未来6G移动通信时代的持续演进能力.聚焦于3GPP 5G NTN的接入网,在简要回顾3GPP Rel-17中引入的第一个5G NTN标准版本的主要内容后,首先介绍2024年6月正式发布的3GPP Rel-18中的技术进展,然后概述近期开启研讨的3GPP Rel-19中的技术议题,最后描述对未来3GPP Rel-20+中技术发展趋势的展望.
Abstract
Among multiple technical routes qualified for building satellite networks,the route which is based on 3GPP 5G NTN and its evolution has its own unique advantages,including fully reusing the mature industry chains of network equipment and terminal for ter-restrial networks,dramatically reducing the difficulty and cost of the development and deployment for space segment,and enabling the smooth and continuous evolution toward the future 6G systems.Focused on RAN for 3GPP 5G NTN,after briefly reviewed the key contents of the first version of 5G NTN standard introduced in 3GPP Rel-17,this paper firstly summarized the technical progress in 3GPP Rel-18 which had been officially published in 2024 June,then introduced the technical topics in 3GPP Rel-19 which had started the formal discussions recently,and finally looked into the technology trends in future 3GPP Rel-20+.
