论文摘要
如今，无人机（UAV）携带的毫米波（MMWAVE）接入点（APS）的按需部署被视为增强5G+网络性能的潜在解决方案。但是，现代无人机的电池寿命限制了此类系统中的飞行时间。在这封信中，我们评估了可行的部署替代方案，以提高用户需求高度波动的领域。这种方法是将基于无人机的MMWave AP降落在附近的建筑物上，而不是徘徊在该地区。在开发的数学框架内，我们通过考虑了就业无人机的完整操作周期来比较机载和降落部署的系统级绩效。我们的数值结果表明，无人机部署选项的选择取决于服务区域和无人机充电站之间的分离距离，无人机电池寿命以及正在使用的空中AP的数量。提出的方法和结果可以支持潜在的5G+网络中基于无人机的MMWAVE AP的有效按需部署。
On-demand deployments of millimeter-wave (mmWave) access points (APs) carried by unmanned aerial vehicles (UAVs) are considered today as a potential solution to enhance the performance of 5G+ networks. The battery lifetime of modern UAVs, though, limits the flight times in such systems. In this letter, we evaluate a feasible deployment alternative for temporary capacity boost in the areas with highly fluctuating user demands. The approach is to land UAV-based mmWave APs on the nearby buildings instead of hovering over the area. Within the developed mathematical framework, we compare the system-level performance of airborne and landed deployments by taking into account the full operation cycle of the employed drones. Our numerical results demonstrate that the choice of the UAV deployment option is determined by an interplay of the separation distance between the service area and the UAV charging station, drone battery lifetime, and the number of aerial APs in use. The presented methodology and results can support efficient on-demand deployments of UAV-based mmWave APs in prospective 5G+ networks.
