1. A method for wireless communication by a user equipment (UE), comprising:
receiving a channel state information (CSI) reporting configuration, the CSI including channel quality information (CQI) and precoder matrix indicator (PMI) feedback;
determining a configured subband size for the CQI feedback and a number of frequency domain (FD) units configured for the PMI feedback corresponding to the subband size for the CQI feedback; and
calculating the CQI feedback for CQI subbands based on at least a portion of the corresponding number of FD units for the PMI feedback, the portion of the number of FD units being based on alignment of the CQI subbands and the number of FD units for the PMI feedback.
