论文摘要
本文研究了在无人机小细胞（DSC）中使用动态水平机会定位（D-HOP）的可行性，并进行了对天线设备效率对最佳DSC高度的影响的中心分析，该高度已被选为最大程度地提高覆盖范围。我们扩展了各向同性天线的通用城市传播模型，以解释定向天线，从而取决于天线适合理想传播模式的能力。这使我们定义了一个封闭形式的表达，以计算通过天线倾斜来维持恒定覆盖的D-HOP实现的速率提高。假设对统一分布的活性用户位置的全面了解，则测试了三种D-HOP技术：在最小的边界圆（SBC）的中心；最大汇总率的点（3月）；以及上述两个中的最中位点（CMP）。通过分析研究和模拟，我们推断出使用电气小且可倾斜的天线时，DSC D-HOP实施是可行的。尽管如此，即使在为独立覆盖范围设计的DSC中，即使在低用户密度方案中，每个用户平均值的平均平均率最高为20-35％，或者在用户密度的方案中达到3-5％。
This paper investigates the feasibility of Dynamic Horizontal Opportunistic Positioning (D-HOP) use in Drone Small Cells (DSCs), with a central analysis on the impact of antenna equipment efficiency onto the optimal DSC altitude that has been chosen in favor of maximizing coverage. We extend the common urban propagation model of an isotropic antenna to account for a directional antenna, making it dependent on the antenna's ability to fit the ideal propagation pattern. This leads us to define a closed-form expression for calculating the Rate improvement of D-HOP implementations that maintain constant coverage through antenna tilting. Assuming full knowledge of the uniformly distributed active users' locations, three D-HOP techniques were tested: in the center of the Smallest Bounding Circle (SBC); the point of Maximum Aggregated Rate (MAR); and the Center-Most Point (CMP) out of the two aforementioned. Through analytic study and simulation we infer that DSC D-HOP implementations are feasible when using electrically small and tiltable antennas. Nonetheless, it is possible to achieve average per user average rate increases of up to 20-35% in low user density scenarios, or 3-5% in user-dense scenarios, even when using efficient antennas in a DSC that has been designed for standalone coverage.
