1. A user equipment (UE) for wireless communication, comprising:
a memory; and
one or more processors, coupled to the memory, configured to:
determine that a set of uplink resources to be used for transmitting a channel state information (CSI) communication is insufficient to permit one or more four-bit sub-band channel quality indicator (CQI) values to be transmitted in the CSI communication;
determine, based at least in part on the determination that the set of uplink resources is insufficient to permit the one or more four-bit sub-band CQI values to be transmitted in the CSI communication, whether the set of uplink resources is sufficient to permit one or more two-bit sub-band differential CQI values to be transmitted in the CSI communication; and
selectively transmit the one or more two-bit sub-band differential CQI values in the CSI communication based at least in part on the determination of whether the set of uplink resources is sufficient to permit the one or more two-bit sub-band differential CQI values to be transmitted in the CSI communication.
