CONVERGE: A Multi-Agent Vision-Radio Architecture for xApps
Filipe B. Teixeira, Carolina Simões, Paulo Fidalgo +4
Telecommunications and computer vision have evolved independently. With the emergence of high-frequency wireless links operating mostly in line-of-sight, visual data can help predi…
A Reinforcement Learning Framework for Mobility Control of gNBs in Dynamic Radio Access Networks
Pedro Duarte, André Coelho, Manuel Ricardo
The increasing complexity of wireless environments, characterized by user mobility and dynamic obstructions, poses challenges for the maintenance of Line-of-Sight (LoS) connectivit…
Joint Mobile IAB Node Positioning and Scheduler Selection in Locations With Substantial Obstacles
Paulo Furtado Correia, Andre Coelho, Manuel Ricardo
Integrated Access and Backhaul (IAB) in cellular networks combines access and backhaul within a wireless infrastructure reducing reliance on fibre-based backhaul. This enables fast…
