Methods, systems, and devices for wireless communications are described. A first user equipment (UE) may determine that the first UE is to receive a sidelink transmission from a second UE, the sidelink transmission comprising a sidelink control channel and a sidelink data channel. The first UE may receive, based at least in part on a first resource configuration for a sidelink feedback channel failing to satisfy a resource threshold associated with transmitting a feedback message, an indication of a second resource configuration from the second UE, the second resource configuration for transmitting the feedback message to the second UE for the sidelink transmission, the second resource configuration satisfying the resource threshold. The first UE may receive the sidelink transmission from the second UE. The first UE may transmit, to the second UE, the feedback message using the second resource configuration.
