Method for performing measurement of terminal in wireless communication system and apparatus therefor

A User Equipment (UE) for performing a measurement in a wireless communication system, the UE comprising:

• a Radio Frequency (RF) unit;
• and
• a processor,
• wherein the processor is configured to:
• receive, via the RF unit, information about a specific cell group to be measured,
• wherein the received information includes at least one of a list of physical cell identifiers (IDs) of a plurality of cells included in the specific cell group and a virtual cell ID for the specific cell group,
• determine a representative value by measuring the specific cell group according to the received information, and
• when the received information includes the virtual cell ID, perform Radio Resource Management (RRM) or Radio Link Monitoring (RLM) based on the representative value,
• wherein the RRM is set to be performed based on a measurement result of the specific cell group being larger than a measurement result of a cell group having a cell ID different than the virtual cell ID.
