US 2023/0412233 A1 · SELECTION OF ADAPTIVE BEAM WEIGHTS FOR HYBRID BEAMFORMING AT MILLIMETER WAVE AND BEYOND FREQUENCIES

Abstract

Certain aspects of the present disclosure provide techniques for wireless communications by a wireless device. The method generally includes determining a classification of electric field behavior of one or more antenna elements of the wireless device. The method generally includes selecting, based on the classification, between a phase-only beam weight control scheme and a phase and amplitude beam weight control scheme for hybrid beamforming using the one or more antenna elements.
