Band-specific power control with multi-band antenna modules

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

• at least one processor;
• at least one memory coupled with the at least one processor;
• and
• instructions stored in the at least one memory and executable by the at least one processor to cause the apparatus to:
• receive a capability message indicating an antenna panel at a user equipment (UE) supports a plurality of frequency subbands of a band;
• transmit, based at least in part on receiving the capability message, a control message indicating a power scaling parameter dedicated to a frequency subband of the band for wireless communications by the antenna panel at the UE;
• and
• receive, from the antenna panel, a signal via the frequency subband at a transmit power that is based at least in part on the power scaling parameter dedicated to the frequency subband.

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

• transmitting a capability message indicating an antenna panel at the UE supports a plurality of frequency subbands of a band;
• receiving, based at least in part on transmitting the capability message, a control message indicating a power scaling parameter dedicated to a frequency subband of the band for wireless communications by the antenna panel at the UE;
• and
• transmitting, by the antenna panel, a signal via the frequency subband at a transmit power that is based at least in part on the power scaling parameter dedicated to the frequency subband.
