Abstract:
1. An interference control method for use in a communication system including a macro base station, a macro terminal communicating with the macro base station, a femto base station, and a femto terminal registered in the femto base station, the interference control method comprising the steps of: measuring reference signal received quality of the femto base station and reference signal quality of the macro base station at the macro terminal; determining whether a difference value between the measured reference signal received quality of the femto base station and the reference signal received quality of the macro base station is greater than a predetermined first threshold value; in response to determining that the difference value between the measured reference signal received quality of the femto base station and the reference signal received quality of the macro base station is greater than a predetermined first threshold value, transmitting a request for activating interference control, the difference value, and identification information of the femto base station from the macro terminal to the macro base station; transmitting to the femto base station specified by the identification information from the macro base station an interference control activation request signaling that the interference control is activated based on the request for activating interference control, the difference value, and the identification information; and performing interference control for the femto terminal registered in the femto base station, based on the interference control activation request signaling at the femto base station.
