Method and apparatus for selecting resources based on partial sensing in NR V2X

A first device adapted to perform wireless communication based on partial sensing, the first device comprising:

• at least one transceiver;
• at least one processor;
• and
• at least one memory connected to the at least one processor and storing instructions that, based on being executed by the at least one processor, cause the first device to perform operations comprising:
• triggering a resource selection procedure;
• determining a selection window within a packet delay budget (PDB) based on the triggering of the resource selection procedure;
• selecting Y candidate slots in the selection window;
• determining a contiguous partial sensing (CPS) window related to the Y candidate slots;
• and
• selecting a sidelink (SL) resource,
• wherein, based on that a number of slots included in the CPS window is less than a minimum number of slots for CPS, the SL resource is selected based on random selection from a resource pool,
• wherein, based on that the number of slots included in the CPS window is greater than or equal to the minimum number of slots for the CPS, the SL resource is selected based on the CPS in the Y candidate slots, and
• wherein Y is a positive integer.
