Methods, systems, and devices for wireless communications are described. A base station may transmit a data message to a user equipment (UE) in a data block modulated according to a modulation and coding scheme (MCS). The UE may monitor for the data block and may attempt to decode the data block. If the UE successfully receives and decodes the data block, the UE may transmit an acknowledgment (ACK) in a feedback message. If the UE unsuccessfully receives or decodes the data block, the UE may transmit a negative acknowledgement (NACK). The UE may transmit the feedback message with the ACK or NACK and a value from a codebook indicating for the base station to increase or decrease the MCS by a delta value for a following transmission or a retransmission.
