DOI: 10.1109/lcomm.2025.3542787
Abstract: This letter studies the coverage performance of the sensing-assisted millimeter wave networks with imperfect beam alignment to guide beamwidth adjustment. A sensing-assisted adaptive beamforming (SABF) scheme is proposed where the transmitted beamwidth is dynamically adjusted… read more here.
