Patent ID: 8676205

Claim:
An operating method of a terminal in a wireless communication system including at least one macro base station and at least one pico base station in a coverage of the macro base station, the method comprising: setting measurement reporting configuration for a blanking trigger; measuring a receive signal strength of the pico base station; comparing the measured receive signal strength with a reference signal strength for the blanking trigger; and when the measured receive signal strength is greater than the reference signal strength for the blanking trigger, transmitting to the macro base station, a measurement report message comprising a measurement identifier corresponding to the measurement reporting configuration for the blanking trigger and a value of the measured receive signal strength, wherein the reference signal strength for the blanking trigger is smaller than a reference signal strength for a handover trigger, wherein the pico base station is configured to perform a blanking operation corresponding to the measurement report message for the blanking trigger, and the blanking operation comprises one of not allocating a certain frequency band to the terminal and allocating the frequency band by limiting a transmit and receive power, and wherein the frequency band comprises a partial frequency band not used by the macro base station and the pico base station at a same time.
