论文摘要
蜂窝连接的无人机市场是5G最有前途的市场之一。但是，它仍然占整体电信市场的一小部分，并且在可预见的将来不太可能大幅度增加。使用上倾斜天线部署专用网络可以选择，但是专用网络的货币成本直接影响了移动运营商的接受。因此，必须开发具有成本效益的空中覆盖解决方案。重用地面覆盖的网络是一种具有成本效益的空中覆盖范围的方法，但是应解决由天线旁边造成的一些关键挑战。在本文中，提出了一种新颖的航空覆盖方法。通过调整测量报告处理机制，可以识别和忽略无人机报告的旁观者信号。仿真结果表明，具有所提出方法的常规蜂窝网络可以以令人满意的质量提供广泛而连续的空中覆盖范围。
The cellular-connected drone market is one of the most promising markets of 5G. However, it still accounts for a small share of overall telecommunication market, and it is unlikely to increase significantly for the foreseeable future. Deploying dedicated network with up-tilted antennas can be an option, but the monetary cost of dedicated network directly impacts the acceptance of mobile operators. Therefore, cost-efficient aerial coverage solutions must be developed. Reusing network for terrestrial coverage is a cost-efficient approach for aerial coverage, but several critical challenges caused by antenna sidelobe should be solved. In this paper, a novel method for aerial coverage is proposed. By tweaking the measurement report handling mechanism, signals from sidelobes reported by drones above the predefined height can be identified and ignored. Simulation results show that the conventional cellular network with the proposed method can provide wide and continuous aerial coverage with satisfactory quality.
