Abstract: Methods, systems, and devices for wireless communications are described. Generally, the described techniques provide for managing timing for inter-user equipment (UE) coordination to prevent or minimize interference or collisions between sidelink transmissions. A first UE may determine a time window in which to select sidelink resources for an inter-UE coordination message based on a minimum time configured for selecting the sidelink resources. The minimum time configured for selecting the sidelink resources for the inter-UE coordination message may be different from a minimum time configured for selecting sidelink resources for other sidelink messages. The first UE may then select the sidelink resources in the time window for the inter-UE coordination message and transmit the inter-UE coordination message on the selected sidelink resources to the second UE over a sidelink.
