Channel Knowledge Maps for FR3 UAV Base Stations: Dataset and ML-based Modeling

Guillem Moreno~Garcia, Sergi Abadal, Evgenii Vinogradov · 2026

This paper introduces a dense upper mid-band Frequency Range (FR3) Channel Knowledge Map (CKM) dataset for Uncrewed Aerial Vehicles (UAVs) with an on-board base station (UxNB). It contains 16,180 CKM samples from 3,236 urban locations in 66 cities at 7.125 GHz and UxNB heights of up to 500 meters. Every 513x513 sample …

Reinforcement Learning-Based 3D Beam Adaptation for Underwater Wireless Optical Communication with AUVs

Viviana Centritto~Arrojo, Ama Bandara, Sergi Abadal وآخرون · 2026

Underwater Wireless Optical Communications (UWOC) provide essential high data rates for Autonomous Underwater Vehicles (AUVs), but reliable connectivity is critically affected by transmitter-receiver misalignment. This work addresses the beam pointing problem for a moving AUV subject to unknown ocean currents through a …
