Method and apparatus for performing V2X communication in a wireless communication system

An operation method of a second terminal in a wireless communication system, the operation method comprising:

• receiving, from a base station, a radio resource control (RRC) reconfiguration message including configuration information associated with measurement of sidelink reference signal received power (SL-RSRP), wherein the configuration information associated with the measurement of the SL-RSRP includes information for a timer related to a periodic reporting regarding the measurement of the SL-RSRP;
• transmitting, to a first terminal, a RRC reconfiguration message including the configuration information associated with the measurement of the SL-RSRP, based on the RRC reconfiguration message received from the base station, wherein the SL-RSRP is measured by the first terminal based on the configuration information associated with the measurement of the SL-RSRP;
• and
• receiving a measurement result of a Layer 3 filtered SL-RSRP from the first terminal,
• wherein the measurement result of the Layer 3 filtered SL-RSRP is received from the first terminal in case that the measurement of the Layer 3 filtered SL-RSRP is performed by the first terminal.

A first terminal in a wireless communication system, the first terminal comprising:

• a transceiver;
• and
• at least one processor configured to:
• receive, from a second terminal through the transceiver, a radio resource control (RRC) reconfiguration message including configuration information associated with measurement of sidelink reference signal received power (SL-RSRP), wherein the configuration information associated with the measurement of the SL-RSRP includes information for a timer related to a periodic reporting regarding the measurement of the SL-RSRP;
• perform measurement of a Layer 3 filtered SL-RSRP, based on the configuration information associated with the measurement of the SL-RSRP;
• and
• transmit, to the second terminal through the transceiver, the measurement result of the Layer 3 filtered SL-RSRP.
