19. A user equipment (UE) for wireless communication, comprising:
a memory; and
one or more processors, coupled to the memory, configured to:
receive an indication of a subband threshold;
determining a quantity of bits used to represent one or more channel quality indicator (CQI) values, corresponding to one or more subbands to be reported in a CQI report,
wherein the quantity of bits used to represent the one or more CQI values is based at least in part on a quantity of the one or more subbands in comparison to the subband threshold, and
wherein:
a first quantity of bits, used to represent the one or more CQI values, corresponds to the quantity of the one or more subbands failing to satisfy the subband threshold, and
a second quantity of bits, used to represent the one or more CQI values, corresponds to the quantity of the one or more subbands satisfying the subband threshold; and
transmit the CQI report comprising the one or more CQI values based at least in part on the determined quantity of bits.
 
24. A user equipment (UE) for wireless communication, comprising:
a memory; and
one or more processors, coupled to the memory, configured to:
determine a quantity of bits used to represent one or more channel quality indicator (CQI) values, corresponding to one or more subbands to be reported in a CQI report,
wherein the quantity of bits used to represent the one or more CQI values is based at least in part on a comparison between a quantity of the one or more subbands and a threshold, and
wherein:
a first quantity of bits, used to represent the one or more CQI values, corresponds to the quantity of the one or more subbands failing to satisfy the threshold, and
a second quantity of bits, used to represent the one or more CQI values, corresponds to the quantity of the one or more subbands satisfying the threshold; and
transmit the CQI report comprising the one or more CQI values based at least in part on the determined quantity of bits.
