[ 5. A method of performing a radio link monitoring by a user equipment (UE) configured with a plurality of cells in a wireless communication system, the method comprising:
receiving, from a base station (BS), information regarding a set of resources of a first cell for the radio link monitoring;
performing the radio link monitoring for the first cell only excluding other cells among the plurality of cells, based on the set of resources of the first cell; and
determining whether a result of the radio link monitoring is ‘out-of-synchronization’ or ‘in-synchronization’ based on a first threshold value (Qout) and a second threshold value (Qin),
wherein the result of the radio link monitoring is determined to be ‘out-of-synchronization’ based on that all radio link qualities of all resources in the set of resources of the first cell other than the other cells is less than the first threshold value (Qout),
wherein the result of the radio link monitoring is determined to be ‘in-synchronization’, based on that any radio link quality of any resource in the set of resources of the first cell other than the other cells is greater than the second threshold value (Qin), and
wherein the information regarding the set of resources includes information for configuring that at least one signal including a first channel state information-reference signal (CSI-RS) is set as a reference signal (RS) for the radio link monitoring from among a plurality of CSI-RSs configured in the UE.]
