Abstract: Methods, systems, and devices for wireless communications are described. Generally, the described techniques provide for reducing the overhead associated with reporting feedback, such as hybrid automatic repeat request (HARQ) feedback. A user equipment (UE) may receive a configuration message from a base station indicating that the UE is to request resources for transmitting negative acknowledgment (NACK) feedback for a downlink transmission. If the UE fails to receive or decode the downlink transmission, the UE may request resources from the base station on which to transmit the NACK feedback for the downlink transmission. Because the UE may be configured to request resources on which to transmit the NACK feedback, the UE may avoid transmitting HARQ feedback for every downlink transmission from the base station. Thus, the base station may avoid allocating resources for HARQ feedback from the UE for every downlink transmission, and the overhead of reporting HARQ feedback is reduced.
