Techniques for per-polarization beam scheduling for multiple-input multiple-output (MIMO) communication

An apparatus for wireless communication at a user equipment (UE), comprising:

• one or more memories that store instructions;
• and
• one or more processors coupled with the one or more memories and configured to execute the instructions to cause the UE to:
• select, from a beamforming codebook and based at least in part on historical information stored at the UE that indicates one or more performance statistics associated with beams in the beamforming codebook, a first transmit beam and a second transmit beam for transmission of an uplink reference signal, the first transmit beam selected from a first set of beams associated with a first polarization in the beamforming codebook and the second transmit beam selected from a second set of beams associated with a second polarization in the beamforming codebook in accordance with the one or more performance statistics associated with the beams in the beamforming codebook;
• transmit, based at least in part on selection of the first transmit beam and the second transmit beam, the uplink reference signal to a network device via both the first transmit beam and the second transmit beam;
• and
• receive, from the network device, a beam report based at least in part on the transmission of the uplink reference signal via the first transmit beam and the second transmit beam.

A method for wireless communication at a user equipment (UE), comprising:

• receiving a downlink reference signal from a network device;
• selecting, from a beamforming codebook and based at least in part on historical information stored at the UE that indicates one or more performance statistics associated with beams in the beamforming codebook, a first receive beam and a second receive beam to be measured for receive beam strength with respect to the downlink reference signal, the first receive beam being selected from a first set of beams associated with a first polarization in the beamforming codebook and the second receive beam being selected from a second set of beams associated with a second polarization in the beamforming codebook in accordance with the one or more performance statistics associated with the beams in the beamforming codebook;
• measuring, based at least in part on selecting the first receive beam and the second receive beam, a receive strength of the downlink reference signal on both the first receive beam and the second receive beam;
• and
• transmitting, to the network device, a beam report that identifies the first receive beam and the second receive beam.
