Method for transmitting and receiving signal in wireless communication system

A first user equipment (UE) in a wireless communication system, comprising:

• at least one processor;
• and
• at least one computer memory operatively connected to the at least one processor and configured to store commands that when executed causes the at least one processor to perform operations,
• wherein the operations include:
• monitoring a physical sidelink control channel (PSCCH) including first sidelink control information (SCI) in an on-duration section;
• based on that at least one sidelink traffic indication about that there is sidelink data to be transmitted from a second UE is received, monitoring a physical sidelink shared channel (PSSCH) including second SCI;
• and
• based on that the at least one sidelink traffic indication about that there is the sidelink data to be transmitted from the second UE is not received, skipping monitoring of the PSSCH including the second SCI.

A processor for performing operations for a base station (BS) in a wireless communication system, the operations comprising:

• monitoring a physical sidelink control channel (PSCCH) including first sidelink control information (SCI) in an on-duration section;
• based on that at least one sidelink traffic indication about that there is sidelink data to be transmitted from a second UE is received, monitoring a physical sidelink shared channel (PSSCH) including second SCI;
• and
• based on that the at least one sidelink traffic indication about that there is the sidelink data to be transmitted from the second UE is not received, skipping monitoring of the PSSCH including the second SCI.

A computer readable storage medium storing at least one computer program that includes a command that, when executed by at least one processor, causes the at least one processor to perform operations for a first user equipment (UE), the operations comprising:

• monitoring a physical sidelink control channel (PSCCH) including first sidelink control information (SCI) in an on-duration section;
• based on that at least one sidelink traffic indication about that there is sidelink data to be transmitted from a second UE is received, monitoring a physical sidelink shared channel (PSSCH) including second SCI;
• and
• based on that the at least one sidelink traffic indication about that there is the sidelink data to be transmitted from the second UE is not received, skipping monitoring of the PSSCH including the second SCI.
