A Ray-Traced Digital Twin for 5G NR Positioning with OpenAirInterface
Nima Chaharbaghi, Florian Kaltenberger, Bartosz Podrygajlo +2
Evaluating 5G positioning on a physical testbed ties every measurement to one propagation environment and one antenna layout, so any question about an alternative deployment requir…
Spatial Upper Bound of Radiated Power in Active Antenna Systems
Dominique Nussbaum, Christ Rizk, Eric Seguenot +4
The assessment of unwanted radiated emissions from Active Antenna Systems (AAS) has become a critical issue in adjacent-band coexistence scenarios. In this paper, we establish the…
A Multi-Armed Bandit Framework for Online Optimisation in Green Integrated Terrestrial and Non-Terrestrial Networks
Henri Alam, Antonio de Domenico, Tareq Si Salem +1
Integrated terrestrial and non-terrestrial network (TN-NTN) architectures offer a promising solution for expanding coverage and improving capacity for the network. While non-terres…
First Results on UAV-aided User Localization Using ToA and OpenAirInterface in 5G NR
Omid Esrafilian, Rakesh Mundlamuri, Florian Kaltenberger +2
This paper considers the challenge of localizing ground users with the help of a radio-equipped unmanned aerial vehicle (UAV) that collects measurements from users. We utilize time…
