A Traffic-Aware QoS-Energy Consumption Tradeoff Study for Integrated 6G TN & NTNs
Azim Akhtarshenas, Henri Alam, Henri Alam† +2
Motivated by the Hypercell concept, we extend BLASTER to investigate the trade-off between network quality of service (QoS) and terrestrial energy consumption in integrated terrest…
Passive AoA Estimation of COTS 5G NR Handsets from Uplink SRS: A Practical USRP-B210 Implementation
Ricardo N. Barrios-Muñoz, Azim Akhtarshenas, David Gomez-Barquero +1
This paper presents a passive network-side framework for estimating the uplink angle of arrival (AoA) of unmodified commercial 5G handsets from native Sounding Reference Signal (SR…
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…
