论文摘要
如今，移动运营商开始部署第五代（5G）网络，以扩大宽带无线服务的覆盖范围。相反，机上连接仍然有限，其服务质量并不总是满足期望。在空对面（A2G）通信系统中拥抱5G新广播（NR）可以帮助缩小空气传播和地面连通性之间的差距。在本文中，我们专注于基于5G NR的直接A2G通信。我们首先提供基于早期移动技术的现有A2G系统的概述。然后，我们在从低于7 GHz到毫米波频率的一系列频段中确认了NR A2G系统的可行性。结果表明，NR A2G系统可以为机上连接提供显着提高的数据速率。我们还确定了与NR A2G通信相关的主要挑战，讨论了应对挑战的增强功能，并指出了未来研究的富有成果的途径。
Today, mobile operators are starting to deploy Fifth-Generation (5G) networks to expand the coverage ubiquity of broadband wireless service. In contrast, in-flight connectivity remains limited and its quality of service does not always meet the expectations. Embracing 5G New Radio (NR) in Air-to-Ground (A2G) communication systems can help narrow the gap between airborne and ground connectivity. In this article, we focus on 5G NR based direct A2G communications. We first provide an overview of the existing A2G systems which are based on earlier generations of mobile technologies. Then we confirm the feasibility of NR A2G systems with a performance study in a range of bands from below 7 GHz to millimeter wave frequencies. The results show that NR A2G systems can provide significantly improved data rates for in-flight connectivity. We also identify the major challenges associated with NR A2G communications, discuss enhancements to counteract the challenges, and point out fruitful avenues for future research.
