Methods, systems, and devices for wireless communications are described. A user equipment (UE) to be scheduled by a scheduler UE in a sidelink system may transmit a first scheduling request (SR) to request sidelink resources. The UE may transmit the first SR via a set of feedback resources. The scheduler UE may transmit, to the UE, a sidelink control message to schedule a sidelink transmission. The sidelink control message may indicate a set of feedback resources mapped to the sidelink transmission. The UE may transmit the scheduled sidelink transmission based on the sidelink control message and may request additional sidelink resources. The UE may transmit a second SR, where the second SR is transmitted via the set of feedback resources mapped to the sidelink transmission.
