1. A method of wireless communication performed by a first user equipment (UE), the method comprising:
determining a first resource selection window relative to a projected listen-before-talk (LBT) completion time for an LBT procedure performed by the first UE, wherein the projected LBT completion time is based on an estimated duration of the LBT procedure;
sensing, based on the determining, in a sidelink resource pool within a shared radio frequency band;
identifying, based on the sensing, a subset of resources from the sidelink resource pool that are within the first resource selection window;
selecting at least a first resource from the subset of resources; and
transmitting, to a second UE using the selected first resource, a sidelink transmission.
