Wireless communications systems and methods related to channel occupancy time (COT) sharing for sidelink communications are provided. A first user equipment (UE) receives, from a second UE, a first sidelink transmission during a first channel occupancy time (COT), where the first COT is associated with the second UE. The first UE determines whether the second UE is one of two or more UEs intended to receive a second sidelink transmission. The first UE transmits, to the two or more UEs, the second sidelink transmission during a portion of the first COT based on COT sharing. The COT sharing is in response to determining the second UE is one of the two or more UEs intended to receive the second sidelink transmission.
