1. A method comprising:
receiving, by a user equipment (UE) from a base station, configuration information related to a configuration of a sidelink resource pool;
performing, by the UE, a sensing based on a sensing window related to the sensing of the UE,
wherein the sensing window is configured based on an available slot including at least one slot;
selecting, by the UE based on a result of the sensing, a resource for a sidelink transmission from among candidate sidelink transmission resources identified within a resource selection window from the resource pool,
wherein a start time of the resource selection window is determined as (i) a time point apart by a first time offset based on a processing time for the UE to select the resource for the sidelink transmission (ii) from a slot related to a time point at which the selection of the sidelink transmission resource is triggered, and
wherein an end time of the resource selection window is determined as (i) a time point apart by a second time offset based on remaining Packet Delay Budget (PDB) of data packet related to the sidelink transmission (ii) from the slot related to the time point at which the selection of the sidelink transmission resource is triggered;
performing, by the UE based on whether a RE-EVALUATION and/or a PRE-EMPTION on the resource is selected based on the result of the sensing to be triggered, the RE-EVALUATION and/or the PRE-EMPTION related to resource re-selection,
wherein a resource for the resource re-selection based on the RE-EVALUATION and/or the PRE-EMPTION is configured based on a remaining slot in which a slot related to the resource selected based on the result of the sensing is excluded from the available slot; and
performing, by the UE based on (i) the resource selected based on the result of the sensing and/or (ii) a resource re-selected based on the RE-EVALUATION and/or the PRE-EMPTION, the sidelink transmission.
