Abstract:
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may select, within a resource selection window, a set of resources in which to transmit over an unlicensed sidelink channel. The UE may attempt a listen before talk (LBT) procedure to initiate a channel occupancy time in which to transmit over the unlicensed sidelink channel. The UE may adjust, within at least a portion of the resource selection window, the set of resources in which to transmit over the unlicensed sidelink channel to be contiguous in at least a time domain based at least in part on the LBT procedure succeeding. The UE may transmit, over the unlicensed sidelink channel, using the set of resources that are adjusted to be contiguous in at least the time domain. Numerous other aspects are provided.
