Method and apparatus for low power sensing for sidelink in wireless communication systems

Apparatuses and methods for low power sensing operations for a sidelink (SL) a wireless communication system a method of operating a user equipment (UE) is provided. The method includes transmitting, on a sidelink SL interface, traffic with a periodicity; operating in a transmit (TX) resource pool with a parameter sl-MultiReserveResource set to enabled; and performing at least partial sensing including: determining a resource selection window, selecting Y slots within the resource selection window, and for each slot, sensing a set of slots. The method further includes determining candidate resources available in the resource selection window after resource exclusion based on the at least partial sensing and performing resource selection within the available candidate resources.
