Matteo Bernabè, David López-Pérez, Nicola Piovesan
Energy consumption remains a dominant operational challenge for current and future cellular systems, especially in dense urban deployments. This paper investigates a novel role for…
Centralized PPO-Based DRL for Multi-UAV-BS Positioning and Trajectory Optimization in Disaster Response Networks
Azim Akhtarshenas, Mario Rico Ibanez, Matteo Bernabe +2
Unmanned aerial vehicle-mounted base stations (UAV-BSs) constitute a flexible and effective solution for global positioning system (GPS)-free emergency and disaster scenarios, wher…
PPO-Based Dynamic Positioning of HAPS-BS in Wind-Disturbed Stratospheric Maritime Networks
Azim Akhtarshenas, German Svistunov, Matteo Bernabè +2
High-Altitude Platform Stations (HAPS) offer a promising solution for wide-area wireless coverage in maritime regions lacking terrestrial infrastructure. However, maintaining relia…
Performance Analysis of Tri-Sector Reflector Antennas for HAPS-Based Cellular Networks
German Svistunov, Matteo Bernabe, David Lopez-Perez
The increasing demand for ubiquitous, highcapacity mobile connectivity has driven cellular systems to explore beyond-terrestrial deployments. In this paper, we present a system-lev…
Capacity and Energy Trade-Offs in FR3 6G Networks Using Real Deployment Data
David López-Pérez, Nicola Piovesan, Matteo Bernabè
This article presents a data-driven system-level analysis of multi-layer 6G networks operating in the upper mid-band (FR3: 7-24 GHz). Unlike most prior studies based on 3rd Generat…
