Abstract

In this work, we consider a UAV-assisted cell in a single user scenario. We consider the Quality of Experience (QoE) performance metric calculating it as a function of the packet loss ratio. In order to acquire this metric, a radio-channel emulation system was developed and tested under different conditions. The system consists of two independent blocks, separately emulating connections between the User Equipment (UE) and unmanned aerial vehicle (UAV) and between the UAV and Base station (BS). In order to estimate scenario usage constraints, an analytical model was developed. The results show that, in the described scenario, cell coverage can be enhanced with minimal impact on QoE.

摘要

在这项工作中，我们考虑单用户场景下的无人机辅助小区。我们将体验质量（QoE）性能指标视为丢包率的函数进行计算。为了获取该指标，开发了一个无线信道仿真系统并在不同条件下进行了测试。该系统由两个独立模块组成，分别模拟用户设备（UE）与无人机（UAV）之间以及无人机与基站（BS）之间的连接。为了估计场景使用限制，开发了一个分析模型。结果表明，在所描述的场景中，可以在对QoE影响最小的情况下增强小区覆盖。
