1. A method for canceling inter-cell interference in a wireless communication system, the method comprising;

  • receiving from a neighbor cell, time resource interference information indicating whether a subframe is a reduced-power almost blank subframe (ABS) or a normal subframe;

    receiving from the neighbor cell, first frequency resource interference information related to the reduced-power ABS and a plurality of first thresholds related to the reduced-power ABS;

    receiving from the neighbor cell, second frequency resource interference information related to the normal subframe and a plurality of second thresholds related to the normal subframe;

    performing downlink communication and uplink communication by using the first frequency resource interference information in the reduced-power ABS; and

    performing downlink communication and uplink communication by using the second frequency resource interference information in the normal subframe,wherein the first frequency resource interference information indicates a range of transmission power of the neighbor cell in the reduced-power ABS based on the plurality of first thresholds, andwherein the second frequency resource interference information indicates a range of transmission power of the neighbor cell in the normal subframe based on the plurality of second thresholds.
