Claim Text:
1. A method for performing mobility by a user equipment (UE) in a wireless communication system, the method comprising: receiving, by the UE from a serving cell operating on a first frequency, a proximity indication configuration message that includes a list of cells operating on a second frequency; detecting, by the UE, whether a specific cell is present in the list of cells operating on the second frequency, wherein the specific cell is a pico cell having a specified coverage; transmitting, by the UE to the serving cell, a proximity indication message that includes an indication indicating that the UE detects the specific cell in the list of cells operating on the second frequency, wherein the indication included in the proximity indication message further indicates that the specific cell is not a closed subscriber group (CSG) cell; receiving, by the UE from the serving cell, a measurement configuration used for measuring the specific cell; measuring, by the UE, the specific cell on the second frequency based on the measurement configuration; transmitting, by the UE to the serving cell, a measurement result when the specific cell operating on the second frequency satisfies a report condition of the measurement result; receiving, by the UE from the serving cell, a handover command message when the serving cell decides to perform the handover of the UE; and performing, by the UE, a handover to the specific cell based on the measurement of the specific cell.
