Hybrid beamforming selection for higher-order MIMO

A network node for wireless communication, comprising:

• a memory;
• and
• one or more processors, coupled to the memory, configured to:
• receive a measurement report indicating a plurality of candidate beam pairs for multiple-input multiple-output (MIMO) communication with a user equipment (UE), wherein the plurality of candidate beam pairs includes a first beam pair and a second beam pair, wherein each beam of the plurality of candidate beam pairs has a spatial characteristic indicating a direction of the beam and a polarization characteristic indicating a polarization of the beam;
• and
• transmit a MIMO configuration for the first beam pair and the second beam pair, wherein a beam of the second beam pair is outside a beam avoidance region, wherein the beam avoidance region is defined based at least in part on the spatial characteristic of a beam of the first beam pair, wherein the beam is within the beam avoidance region.

A method of wireless communication performed by a user equipment (UE), comprising:

• generating a measurement report indicating a plurality of candidate beam pairs for multiple-input multiple-output (MIMO) communication with a network node, wherein the plurality of candidate beam pairs includes a first beam pair and a second beam pair, wherein each beam of the plurality of candidate beam pairs has a spatial characteristic indicating a direction of the beam and a polarization characteristic indicating a polarization of the beam;
• transmitting the generated measurement report;
• and
• receiving a MIMO configuration for the first beam pair and the second beam pair, wherein a beam of the second beam pair is outside a beam avoidance region, wherein the beam avoidance region is defined based at least in part on the spatial characteristic of a beam of the first beam pair, wherein the beam is within the beam avoidance region.
