Apparatus and method for processing sidelink resource required for sidelink DRX operation in wireless communication system

A method performed by a second user equipment (UE) in a wireless communication system supporting a sidelink (SL) communication, the method comprising:

• receiving, from a first UE, first information for configuring a SL discontinuous reception (DRX) and second information associated with a channel state information (CSI) report of the SL including SL measurement configuration information, configuration information for a CSI, and an indication not to perform the CSI report when the second UE is not in an active time of the SL DRX;
• receiving, from the first UE, a SL channel state information (CSI) report request;
• and
• transmitting, to the first UE, the SL CSI report within the active time based on the first information and the second information,
• wherein the active time for the SL DRX is associated with the reception of the SL CSI report request and the transmission of the SL CSI report.

A first user equipment (UE) in a wireless communication system supporting a sidelink (SL) communication, the first UE comprising:

• a transceiver;
• and
• a controller, coupled with the transceiver, configured to:
• transmit, to a second UE, first information for configuring a SL discontinuous reception (DRX) and second information associated with a channel state information (CSI) report of the SL including SL measurement configuration information, configuration information for a CSI, and an indication not to perform the CSI report when the second UE is not in an active time of the SL DRX,
• transmit, to the second UE, a SL CSI report request, and
• receive, from the second UE, the SL CSI report within the active time based on the first information and the second information,
• wherein the active time for the SL DRX is associated with the transmission of the SL CSI report request and the reception of the SL CSI report.
