摘　　要：为满足乘客对空中上网日益强烈的需求,实现地面网络与天基网络的互联互通和优势互补,天地协同组网成为5G移动通信演进的技术方向之一。相比于时延长、成本高的卫星宽带接入,ATG地空通信系统时延短、成本低、速率快,具有良好的应用前景。为研究ATG业务需求,首先基于5G技术分析了ATG地空通信系统的组网形式,然后对飞机位于ATG基站不同位置时3400-3500 MHz 5G NR频段的系统容量进行了分析比较,通过分析证明,将3.5 GHz 5G NR频段用于ATG业务能够很好地满足其业务需求。In order to meet the increasing demand of passengers for Internet access in the air and realize the interconnection and complementary advantages of the ground network and the space-based network,the space-ground collaboration network has become one of the technical directions of 5G mobile communication evolution.Compared with the satellite broadband access with the long latency and high cost,the ATG(Air to Ground)communication system has short time delay,low cost and fast rate,and hence has a favorable application prospect.To study ATG service requirements,this paper firstly analyzes the networking form of the ATG communication system based on 5G technologies,and then analyzes and compares the system capacity of the 3400~3500 MHz 5G NR frequency band when the airplane is located at different positions of the ATG base station.Through analysis,using the 3.5GHz 5G NR band for ATG services can well meet the service requirements.
