Abstract
The present application relates to a method for central node (CN) to remove inter-cell interference of an access point (AP) in a wireless access system according to the present invention, including: receiving feedback information at each time slot from a plurality of APs, the feedback information including channel measurement information between terminals in each AP and the coverage of each AP, or position information of each AP; obtaining a preference for each pattern, the pattern representing an ON or OFF operation of each AP at each time slot; determining a target time rate of each pattern on the basis of the obtained preference for each pattern; receiving an instantaneous transfer rate of terminals in the coverage of each AP for each pattern from the plurality of APs; and determining a pattern in order to minimize reference between each AP according to the received instantaneous transfer rate.
