Patent ID: 8514811

Claim:
A method of performing a handover procedure of a femto base station in a wireless communication system in which a macro base station and the femto base station coexist, the method comprising: detecting an uplink signal transmitted from a terminal to the macro base station; sending a report message including information about the uplink signal to the macro base station, the information about the uplink signal including information about a section in which an intensity of the uplink signal is greater than a reference value, the information about the section including Masked Cyclic Redundancy Check (MCRC) information about the section, information about a beginning time and a length of the section: and when the macro base station triggers handover based on the report message, performing the handover procedure with the terminal that is identified by the macro base station as a terminal to which an uplink resource has been allocated during the section, wherein the terminal is unable itself to trigger the handover because a difference between an intensity of a signal received from the macro base station and an intensity of a signal received from the femto base station is not sufficient.
