Aspects of the present disclosure relate to wireless communications, and more particularly, to techniques for providing quantized channel state information (CSI) feedback that may be used to adjust transmission parameters for retransmissions after a negative acknowledgment. An example method performed by a user equipment (UE) generally includes generating hybrid automatic repeat request (HARQ) feedback for a downlink transmission from a network entity, generating quantized channel state information (CSI) feedback, transmitting the HARQ feedback and quantized CSI feedback to the network entity in a physical uplink control channel (PUCCH) transmission, and processing a retransmission of the downlink transmission, sent with transmission parameters adjusted based on the quantized CSI feedback if the HARQ feedback indicates a decoding failure.
