Apparatus and method for power control using small base stations

A power control method of a target power device among a plurality of power devices controlled through a wireless communication system comprising a small base station and a macro base station, the method comprising:

• receiving, from the small base station, a control signal for controlling power of the target power device;
• controlling a power ON/OFF device that performs power ON or power OFF of the target power device based on the control signal;
• and
• executing one of power ON and power OFF of the target power device through controlling of the power ON/OFF device,
• wherein the control signal comprises a power device identifier (ID) field including an ID of the target power device, a small base station ID field including an ID of the small base station, and an ON/OFF field indicating one of power ON and power OFF of each of the at least one power device.

A small base station to perform power control in a wireless communication system comprising the small base station and a macro base station, the small base station comprising:

• a user detector to detect a presence of a user terminal by monitoring whether a registration state of the user terminal served by the small base station corresponds to a registration complete state, a registration maintain state, or a registration release state;
• a control signal generator to generate a control signal for controlling power of at least one power device among a plurality of power devices included in a predetermined group, based on the detection result;
• and
• a control signal transmitter to transmit the control signal to the at least one power device among the plurality of power devices.

A target power device among a plurality of power devices controlled through a wireless communication system comprising a small base station and a macro base station, the target power device comprising:

• a control signal receiver to receive, from the small base station, a control signal for controlling power of the target power device;
• a power control unit to control a power ON/OFF device that performs power ON or power OFF of the target power device based on the control signal;
• and
• the power ON/OFF device to execute one of power ON and power OFF of the target power device through controlling of the power ON/OFF device,
• wherein the control signal comprises a power device identifier (ID) field including an ID of the target power device, a small base station ID field including an ID of the small base station, and an ON/OFF field indicating one of power ON and power OFF of each of the at least one power device.
