Method and apparatus for configuring parameters in vehicle-to-everything system

A first terminal configured to perform vehicle-to-everything (V2X) communication in a wireless communication system, comprising:

• a transceiver configured to transmit and receive a signal;
• and
• a controller configured to:
• receive, from a base station, a V2X system information block (V2X-SIB) including resource pool information associated with a second terminal, the resource pool information including a first parameter associated with a numerology for the first terminal and a second parameter associated with a numerology for the second terminal,
• identify whether the first parameter is different from the second parameter based on the V2X-SIB,
• determine at least one parameter associated with a numerology of a sidelink signal to be transmitted to the second terminal based on the second parameter, in case that the first parameter and the second parameter are different, and
• transmit, to the second terminal, the sidelink signal based on the determined at least one parameter.

A method for vehicle-to-everything (V2X) communication performed by a second terminal in a wireless communication system, the method comprising:

• receiving, from a base station, a V2X system information block (V2X-SIB) including resource pool information associated with a first terminal, the resource pool information including a first parameter associated with a numerology for the first terminal and a second parameter associated with a numerology for the second terminal;
• identifying whether the first parameter is different from the second parameter based on the V2X-SIB;
• determining at least one parameter associated with a numerology of a sidelink signal to be received from the first terminal based on the first parameter, in case that the first parameter and the second parameter are different;
• and
• receiving, from the first terminal, the sidelink signal based on the determined at least one parameter.
