Method and user equipment for sidelink packet exchange operation

A method performed by a first User Equipment (UE) for a Sidelink (SL) packet exchange operation, the method comprising:

• receiving at least one SL-Discontinuous Reception (SL-DRX) configuration and a plurality of SL resource pool configurations to be configured on the first UE;
• performing partial sensing based on at least one of the plurality of SL resource pool configurations when an SL-DRX operation is performed based on the at least one SL-DRX configuration, each of at least one SL resource pool configured by the at least one of the plurality of SL resource pool configurations comprising one or more time slots;
• and
• performing SL-Channel Busy Ratio (SL-CBR) measurement associated with each of the at least one SL resource pool in the one or more time slots where the partial sensing is performed.

A User Equipment (UE) in a wireless communication system for a Sidelink (SL) packet exchange operation, the wireless communication system comprising a Base Station (BS), the UE comprising:

• one or more non-transitory computer-readable media having computer-executable instructions embodied therein;
• and
• at least one processor coupled to the one or more non-transitory computer-readable media, the at least one processor configured to execute the computer-executable instructions to cause the UE to:
• receive at least one SL-Discontinuous Reception (SL-DRX) configuration and a plurality of SL resource pool configurations to be configured on the UE;
• perform partial sensing based on at least one of the plurality of SL resource pool configurations when an SL-DRX operation is performed based on the at least one SL-DRX configuration, each of at least one SL resource pool configured by the at least one of the plurality of SL resource pool configurations comprising one or more time slots;
• and
• perform SL-Channel Busy Ratio (SL-CBR) measurement associated with each of the at least one SL resource pool in the one or more time slots where the partial sensing is performed.
