1. A first user equipment (UE) configured for wireless communication, the first UE comprising:
a memory storing processor-readable code; and
at least one processor coupled to the memory, the at least one processor configured to execute the processor-readable code to cause the at least one processor to:
determine, based on a projected listen-before-talk (LBT) completion time, a resource selection window;
sense, in response to the determination, in a sidelink resource pool within a shared communication band for:
a subset of resources from the sidelink resource pool that are within the resource selection window, and
channel occupancy time (COT) sharing information (COT-SI) from one or more neighboring UEs, wherein the COT-SI includes identification of a COT initiated by the one or more neighboring UEs and one or more parameters associated with the COT;
identify, based on results of the sensing, one or more in-COT resources of the subset of resources located within the COT and one or more out-of-COT resources of the subset of resources located outside of the COT;
select, in response to the identification of the one or more in-COT resources and the one or more out-of-COT resources and a resource selection trigger, a set of transmission resources from the in-COT resources or from the out-of-COT resources; and
transmit to a second UE via the set of transmission resources.
