论文摘要
在将来的无人机应用程序中，快速移动的无人机（UAV）将需要通过高吞吐量超可靠的无线链接连接。 MMWave通信被认为是无人机通信的一种有前途的技术，因为狭窄的光束很少受到往返地面的干扰。此类网络的挑战是波束形成的要求，并且由于单元很小而需要经常进行移交。在无人机的通信研究界，通常会忽略移动性，尤其是移交性，但是，在考虑光束形成时，天线阵列的大小开始重要，方位角和高程的效果应被研究，尤其是它们对移交率和中断能力的影响。本文旨在填补一些知识差距，并阐明现有问题。这项工作将通过使用MMWave对现实的5G部署进行案例研究，分析无人机网络3D波束形成和移交的性能。我们将利用波束形成的MMWave链接来查看无人机飞越城市的表现。
In future drone applications fast moving unmanned aerial vehicles (UAVs) will need to be connected via a high throughput ultra reliable wireless link. MmWave communication is assumed to be a promising technology for UAV communication, as the narrow beams cause little interference to and from the ground. A challenge for such networks is the beamforming requirement, and the fact that frequent handovers are required as the cells are small. In the UAV communication research community, mobility and especially handovers are often neglected, however when considering beamforming, antenna array sizes start to matter and the effect of azimuth and elevation should be studied, especially their impact on handover rate and outage capacity. This paper aims to fill some of this knowledge gap and to shed some light on the existing problems. This work will analyse the performance of 3D beamforming and handovers for UAV networks through a case study of a realistic 5G deployment using mmWave. We will look at the performance of a UAV flying over a city utilizing a beamformed mmWave link.
