Method and apparatus for providing power saving of monitoring for device-to-device communication in a wireless communication system

A method of a first UE (User Equipment) for performing sidelink communication, comprising:

• the first UE is (pre-)configured with a sidelink resource pool in a carrier or cell;
• the first UE transmits a sidelink transmission to a second UE for requesting a second DRX pattern, wherein the sidelink transmission includes information associated with a first DRX (Discontinuous Reception) pattern of the first UE;
• the first UE receives a specific message from the second UE, wherein the specific message includes information associated with the second DRX pattern;
• and
• the first UE performs monitoring sidelink control information in the sidelink resource pool based on the second DRX pattern.

A first UE (User Equipment) for performing sidelink communication, comprising:

• a memory;
• and
• a processor operatively coupled with the memory, wherein the processor is configured to execute program code to:
• be (pre-)configured with a sidelink resource pool in a carrier or cell;
• transmit a sidelink transmission to a second UE for requesting a second DRX (Discontinuous Reception) pattern, wherein the sidelink transmission includes information associated with a first DRX pattern of the first UE;
• receive a specific message from the second UE, wherein the specific message includes information associated with the second DRX pattern;
• and
• perform monitoring of sidelink control information in the sidelink resource pool based on the second DRX pattern.
