Method and device for measuring sidelink signal in wireless communication system

A method performed by a base station in a wireless communication system, the method comprising:

• transmitting, to a user equipment (UE), configuration information including information associated with a condition for triggering a measurement report event;
• and
• receiving a report on a measurement result from the UE based on satisfaction of the condition,
• wherein whether the condition is satisfied is determined based on the configuration information and a measurement associated with at least one layer 2 (L2) UE-to-network (U2N) relay UE,
• wherein the information includes at least one of a first threshold associated with a sidelink reference signal received power (SL-RSRP) or a second threshold associated with a sidelink discovery reference signal received power (SD-RSRP), and the first threshold and the second threshold are associated with a measurement for a serving L2 U2N relay UE, and
• wherein the information further includes a third threshold associated with a measurement for a candidate L2 U2N relay UE.

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

• a transceiver;
• and
• at least one processor,
• wherein the at least one processor is configured to:
• receive, from a base station, configuration information including information associated with a condition for triggering a measurement report event;
• perform a measurement associated with at least one layer 2 (L2) UE-to-network (U2N) relay UE;
• determine whether the condition is satisfied based on the configuration information and the measurement;
• and
• transmit a report on a measurement result to the base station based on satisfaction of the condition,
• wherein the information includes at least one of a first threshold associated with a sidelink reference signal received power (SL-RSRP) or a second threshold associated with a sidelink discovery reference signal received power (SD-RSRP), and the first threshold and the second threshold are associated with measurement for a serving L2 U2N relay UE, and
• wherein the information further includes a third threshold associated with a measurement for a candidate L2 U2N relay UE.
