Method for mitigating inter-cell interference in wireless communication system and device therefor

An apparatus for canceling inter-cell interference in a wireless communication system, the apparatus comprising:

• a radio frequency module configured to transceiver wire/wireless signals;
• and
• a processor configured to:
• receive from a neighbor cell, time resource interference information indicating whether a subframe is a reduced-power almost blank subframe (ABS) or a normal subframe through the radio frequency module,
• receive 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 through the radio frequency module,
• receive 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 through the radio frequency module,
• perform downlink communication and uplink communication by using the first frequency resource interference information in the reduced-power ABS, and
• perform 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, and
• wherein 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.
