1. A method for wireless communication at a first user equipment (UE), comprising:
transmitting a first communication to at least a second UE during a first channel occupancy time of the first UE for sidelink communications in a shared radio frequency spectrum band;
reserving at least a first resource for a retransmission of the first communication in a second channel occupancy time for sidelink communications in the shared radio frequency spectrum band, wherein the first resource is indicated relative to a start time of the second channel occupancy time, and wherein the start time of the second channel occupancy time is based at least in part on a listen before talk procedure associated with the second channel occupancy time;
determining, after the reserving, the start time of the second channel occupancy time in the shared radio frequency spectrum band; and
retransmitting the first communication to at least the second UE using the first resource, wherein a timing for the first resource is based at least in part on the determined start time of the second channel occupancy time.
