摘要
随着信息化技术的飞速发展,我国通信技术取得了重大的突破。近年来,5G通信技术已广泛应用于通信、交通、航空等各类生产生活场景中。在5G网络通信系统中,5G NTN(Non-Terrestrial Network)技术,又称为5G非地面网络技术,主要应用于卫星通信与低空通信等领域。5G NTN技术的出现标志着我国5G通信技术正式进入空间通信领域,使5G全领域覆盖成为可能实现的目标。首先介绍了目前5G通信中NTN技术应用的典型场景,其次分析了对5G NTN网络的组成与架构以及发展现状,再次对现阶段5G NTN的关键技术展开了深入研究,最后提出了5G通信中NTN关键技术的未来展望,为后续5G非地面网络技术的演化与研究提供有价值的参考。
With the rapid development of information technology,China has made significant breakthroughs in communication technology,and in recent years,5G communication technology has been widely applied in various production and life scenarios such as communications,transportation and aviation.In the 5G network communica⁃tion system,5G NTN technology,also known as 5G non-terrestrial network technology,is a key technology mainly applied in scenarios such as satellite communications and low-altitude communications,and the emergence of 5G NTN technology signifies the official entry of China's 5G communication technology into the space commu⁃nication field,making it possible to achieve the goal of 5G full-field coverage.This article first introduces the cur⁃rent typical scenarios of NTN technology application in 5G communications,then analyzes the composition,archi⁃tecture and development status of the 5G NTN,next conducts an in-depth research on the key technologies of the 5G NTN at the current stage,and finally proposes future prospects for the key technologies of the NTN in 5G communications,which provides valuable reference for the follow-up evolution and research of 5G NTN technology.
