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.
Claims29
An apparatus configured for wireless communications, the apparatus comprising:
- memory comprising computer-executable instructions;
- and
- one or more processor coupled with the memory and configured to, individually or collectively, execute the computer-executable instructions to cause the apparatus to:
- determine a classification of electric field behavior of one or more antenna elements of the apparatus;
- select, 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;
- signal, to a base station, an indication that the apparatus will use the selected phase-only beam weight control scheme or the selected phase and amplitude beam weight control scheme;
- and
- communicate with the base station using the selected phase-only beam weight control scheme or the selected phase and amplitude beam weight control scheme.
An apparatus configured for wireless communications, the apparatus comprising:
- memory comprising computer-executable instructions;
- and
- one or more processors coupled with the memory and configured to, individually or collectively, execute the computer-executable instructions to cause the apparatus to:
