论文摘要
飞机小屋是没有移动宽带的最后一个场所之一。考虑到未来的5G应用程序和连接性要求，直接空对地面通信（DA2GC）是唯一可以通过直接通信链接为飞机提供高容量和低延迟回程链接的技术。为此，我们提出了一个分析框架，以使用双极化的混合DA2GC天线阵列进行多用户边际形成DA2GC网络的地面站部署问题。此外，提议的框架被用来分析和优化DA2GC网络的总拥有成本（TCO），以为欧洲领空提供覆盖范围。我们介绍了不同网络参数之间的相互作用：计算地面站的数量，阵列大小，传输功率和带宽以及TCO优化部署参数以满足容量要求。最后，我们表明，根据不同网络资源的成本，可以设计陆地蜂窝网络，以覆盖整个欧洲领空，其地面站有限，分别具有一定的阵列大小，即地面站和空中站的900和361天线元件。
Aircraft cabin is one of the last venues without mobile broadband. Considering future 5G applications and connectivity requirements, direct air-to-ground communications (DA2GC) is the only technique which can provide high capacity and low latency backhaul link for aircraft via a direct communication link. To this end, we propose an analytical framework to investigate the ground station deployment problem for DA2GC network employing multi-user beamforming with dual-polarized hybrid DA2GC antenna arrays. In addition, the proposed framework is utilized to analyze and optimize the total cost of ownership (TCO) of the DA2GC network to provide coverage for European airspace. We present the interplay between different network parameters: the number of ground stations, array size, transmit power and bandwidth, and TCO optimizing deployment parameters are calculated in order to satisfy capacity requirements. At the end, we show that, depending on the cost of different network resources, a terrestrial cellular network can be designed to cover the whole European airspace with limited number of ground stations with a certain array size, i.e., 900 and 361 antenna elements for ground station and air station, respectively.
