Power control and resource management method of femtocell base station in wideband wireless access system

A method for a macrocell base station to control power of a femtocell base station located in a macrocell of the macrocell base station in a wideband wireless access system in which macrocells and femtocells coexist comprising:

• receiving first received signal strength on a signal provided by the macrocell base station and femtocell information from the femtocell base station;
• calculating a difference value between the first received signal strength and second received signal strength measured by the macrocell terminal in the macrocell by using a signal provided by the macrocell base station;
• when the difference value is less than a threshold value, receiving third received signal strength measured by the macrocell terminal by using a signal provided by the femtocell base station from the macrocell terminal;
• determining whether the macrocell terminal is located in the coverage of the femtocell base station based on the third received signal strength;
• and
• transmitting power control information for controlling power of the femtocell base station to the femtocell base station based on the determination result.

A method for a femtocell base station and a macrocell base station in cooperation with each other to control a radio resource in a wideband wireless access system in which macrocells and femtocells coexist comprising:

• the femtocell base station transmitting first received signal strength on a signal provided by the macrocell base station and femtocell information including preamble information and femtocell base station identifier of the femtocell base station to the macrocell base station;
• the macrocell base station transmitting control information generated based on at least one of a difference value between the first received signal strength and second received signal strength measured by a corresponding macrocell terminal by using a signal provided by the femtocell base station, and third received signal strength measured by the macrocell terminal by using a signal provided by the femtocell base station to the femtocell base station;
• and
• the femtocell base station determining whether to use a specific radio resource agreed in advance with the macrocell base station based on the control information.
