Channel state information codebook parameter configuration for dynamic antenna port adaptation

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

• at least one processor;
• and
• at least one memory coupled with the at least one processor, with instructions stored in the at least one memory, the instructions being executable by the at least one processor to cause the apparatus to:
• receive, via a control message, a channel state information report configuration comprising a first set of codebook parameters associated with at least a first codebook, the first codebook associated with a channel state information measurement at the UE;
• determine a second set of codebook parameters associated with a second codebook based at least in part on the first set of codebook parameters associated with the first codebook;
• and
• transmit, via a physical uplink control channel, a channel state information report that comprises a respective set of subband channel state information parameters and a respective set of wideband channel state information parameters for each of the first codebook and the second codebook based at least in part on the first set of codebook parameters, the second set of codebook parameters, and a channel state information computation at the UE.
