Switching between polarization and spatial multiple-input-multiple-output based on a multiband antenna

An apparatus for wireless communication at a network node, comprising:

• a memory;
• and
• one or more processors, coupled to the memory, the one or more processors individually or collectively configured to:
• receive a first indication of a multiple-input-multiple-output (MIMO) configuration threshold that is associated with a selection between a polarized MIMO configuration and a spatial MIMO configuration, the MIMO configuration threshold being based at least in part on a performance threshold;
• transmit a second indication of a MIMO communication configuration that specifies the selection;
• receive a third indication of an updated MIMO configuration threshold;
• and
• select an updated MIMO communication configuration based at least in part on the updated MIMO configuration threshold.

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

• transmitting a first indication of a multiple-input-multiple-output (MIMO) configuration threshold that is associated with a selection between a polarization MIMO configuration and a spatial MIMO configuration, the MIMO configuration threshold being based at least in part on a performance threshold;
• receiving a second indication of a MIMO communication configuration that specifies the selection;
• obtaining an updated MIMO configuration threshold based at least in part on a set of reference signals;
• and
• transmitting a third indication of the updated MIMO configuration threshold.
