Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may include an L shaped antenna module, which may include a first array of antenna elements in one dimension and a second array of antenna elements in a second dimension. In an L shaped antenna module, antenna element configurations may be used that combine antenna elements across the two sides of the “L”. In some aspects, a UE may dynamically select a configuration of antenna elements of an L shaped antenna module to enhance performance and power consumption. In some aspects, the UE may select whether to use a cross-polarization configuration or a co-polar configuration for the L shaped antenna module.

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.
