Method and apparatus for wireless communication in wireless communication system

A method by a base station supporting a vehicle-to-everything (V2X) communication in a wireless communication system, the method comprising:

• receiving, from a terminal, a first message including assistance information associated with a semi-persistent scheduling (SPS) for the V2X communication;
• transmitting, to the terminal, a second message including SPS configuration information for the V2X communication;
• and
• transmitting, to the terminal, a third message including downlink control information (DCI) associated with activation of the SPS for the V2X communication,
• wherein data is transmitted from the terminal to another terminal based on the SPS configuration information and the DCI, and
• wherein the assistance information associated with the SPS includes at least one of period information and timing offset information.

A terminal performing a vehicle-to-everything (V2X) communication in a wireless communication system, the terminal comprising:

• a transceiver;
• and
• a controller coupled with the transceiver and configured to control to:
• transmit, to a base station, a first message including assistance information associated with a semi-persistent scheduling (SPS) for the V2X communication;
• receive, from the base station, a second message including SPS configuration information for the V2X communication;
• receive, from the base station, a third message including downlink control information (DCI) associated with activation of the SPS for the V2X communication;
• and
• transmit, to another terminal, data based on the SPS configuration information and the DCI,
• wherein the assistance information associated with the SPS includes at least one of period information and timing offset information.
