本文通过系统级仿真评估系留无人机基站构成的5G非地面网络在密集城市的下行性能，发现其每用户吞吐量优于地面5G，尤其对小区边缘和低信干噪比用户增益最大，但需优化飞行高度以平衡视距与损耗干扰。

本文评估了通过系留无人机（TUAV）搭载基站实现的5G非地面网络（NTN）的下行链路性能，并在现实密集城市场景中将其与传统5G地面网络（TN）进行比较。与电池受限的无人机不同，TUAV通过轻型电缆连接到地面站，能够实现稳定定位和近乎视距的用户链路，而不受非系留平台的续航限制。使用符合3GPP规范的多小区六边形布局，包含19个站点和57个扇区，我们对100至1000米高度的TUAV进行建模，并通过系统级仿真评估平均有效信干噪比（SINR）和用户吞吐量。结果表明，基于TUAV的NTN部署在每用户吞吐量方面可显著优于地面5G，其中对小区边缘和低SINR用户观察到的增益最大，前提是适当选择TUAV高度，以在改善视距概率与增加的高空传播损耗和干扰之间取得平衡。
英文摘要
This paper evaluates the downlink performance of 5G non-terrestrial networks (NTNs) realized via tethered unmanned aerial vehicle (TUAV)-mounted base stations, and compares it against conventional 5G terrestrial networks (TNs) in a realistic dense urban scenario. Unlike battery-limited UAVs, TUAVs are connected to ground stations via lightweight cables, enabling stable positioning and near-line-of-sight links to users without the endurance constraints of untethered platforms. Using a 3GPP-compliant multi-cell hexagonal layout with 19 sites and 57 sectors, we model TUAV altitudes ranging from 100 to 1000\,m and evaluate the average effective signal-to-interference-plus-noise ratio (SINR) and user throughput via system-level simulations. Results show that TUAV-based NTN deployments can significantly outperform terrestrial 5G in per-user throughput, with the largest gains observed for cell-edge and low-SINR users, provided the TUAV altitude is properly chosen to balance improved line-of-sight probability against increased propagation loss and interference at higher altitudes.
