Methods, systems, and devices for wireless communications are described. In some systems, a user equipment (UE) may communicate with other UEs via sidelinks during sidelink communication resources assigned by a base station. However, due to the propagation delay of signals in a wireless communications system, a first UE may receive a sidelink transmission from a second UE in resources delayed with respect to the resources used for transmission. If the delay results in a scheduling conflict (e.g., overlapping resources for reception), the first UE may transmit a timing request to resolve the conflict. In a first example, the base station may receive the request and configure a timing gap based on the request. In a second example, the timing request may indicate to the second UE a sidelink transmission timing adjustment for communicating with the first UE, and the second UE may determine whether to implement this timing adjustment.
