Mobile Base Station Positioning in Smart Ports Based on Kriged Sparse Measurements and Obstacle Inference
Paulo Furtado Correia, André Coelho, Manuel Ricardo
Smart-port wireless networks suffer from dynamic radio blockage caused by container stacks and industrial structures, challenging efficient mobile integrated access and backhaul (M…
A Vision-based Framework for Intelligent gNodeB Mobility Control
Pedro Duarte, André Coelho, Francisco Ribeiro +3
This paper proposes a vision-based framework for the intelligent control of mobile Open Radio Access Network (O-RAN) base stations (gNBs) operating in dynamic wireless environments…
Modular Design and Experimental Evaluation of 5G Mobile Cell Architectures Based on Overlay and Integrated Models
José Ruela, Ivan Cojocaru, André Coelho +2
This paper presents the concept, architectural design, and performance evaluation of a 5G Mobile Cell (MC) used to provide 5G wireless connectivity to User Equipment (UE) in areas…
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…
On-demand 5G Private Networks using a Mobile Cell
André Coelho, José Ruela, Gonçalo Queirós +6
This paper proposes the Mobile Cell (MC) concept for on-demand 5G private networks. The MC is designed to extend, restore, and reinforce 5G wireless coverage and network capacity o…
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…
Positioning of a Next Generation Mobile Cell to Maximise Aggregate Network Capacity
Paulo Furtado Correia, Andre Coelho, Manuel Ricardo
In wireless communications, the need to cover operation areas, such as seaports, is at the forefront of discussion, especially regarding network capacity provisioning. Radio networ…
Vision-Radio Experimental Infrastructure Architecture Towards 6G
Filipe B. Teixeira, Manuel Ricardo, André Coelho +7
Telecommunications and computer vision have evolved separately so far. Yet, with the shift to sub-terahertz (sub-THz) and terahertz (THz) radio communications, there is an opportun…
