| 摘 要： |
The recent natural disasters, such as the Earthquake in Morocco in September 2023, have demonstrated one more time the necessity of immediately restoring lost connectivity to rescue victims living in rural villages that are far from urban areas. In such a framework, three-dimensional (3D) Non-Terrestrial Networks (NTNs) are expected to provide continuous wireless coverage at low Average Revenue Per User (ARPU), in disaster-hit and hotspot areas with the help of 5G New Radio (NR). This paper investigates the use of Unmanned Aerial Vehicles (UAV) as transparent aerial networks that perform signal amplification and frequency conversion between a satellite-based 5G network and a User Equipment (UE) using five different frequency bands (i.e., S-band, C-band, X-band, Ku-band, and Ka-band) supporting the satellite communication. The applications of the proposed technology concern connection-critical scenarios like emergency rescue and digital divide mitigation. Results show that 180Mbps to 4.85Gbps throughput can be achieved on the satellite-to-UAV link. Simulated transmission delay and average session time are also evaluated considering a delay budget of 2ms. The related results discussion confirms the viability and effectiveness of the proposed approach in the concerned case of study.
近期的自然灾害，例如2023年9月摩洛哥发生的地震，再次证明了必须立即恢复与偏远农村地区受灾群众之间的通信联系。在此背景下，三维（3D）非地面网络（NTNs）有望借助5G新无线电（NR）技术，在受灾区域和热点区域实现低平均用户收入（ARPU）下的持续无线覆盖。本文研究了无人机（UAV）作为透明空中网络的应用，通过五个不同的频段（即S波段、C波段、X波段、Ku波段和Ka波段）在卫星5G网络与用户设备（UE）之间进行信号放大和频率转换，以支持卫星通信。该技术的应用场景包括紧急救援和缩小数字鸿沟等对连接性要求较高的情况。结果表明，卫星到无人机链路可实现180 Mbps至4.85 Gbps的吞吐量。同时，还评估了在2毫秒延迟预算下的仿真传输延迟和平均会话时长。相关结果讨论证实了所提出方法在该研究案例中的可行性和有效性。 |
