Abstract:
1. A method for a central node (CN) to remove inter-cell interference of an access point (AP) in a wireless access system, the method comprising: receiving, by the CN, feedback information from a plurality of APs every time slot, the feedback information including channel measurement information between each AP and a user equipment (UE), which belongs to coverage of each AP, or position information of each AP; obtaining, by the CN, a preference for each pattern, the pattern representing an ON or OFF operation of each AP every time slot; determining, by the CN, a target time rate of each pattern on a basis of the obtained preference for each pattern; receiving, by the CN, an instantaneous transmission rate of UEs in the coverage of each AP for each pattern from the plurality of APs; and determining, by the CN, a pattern in order to minimize reference between the respective APs in accordance with the received instantaneous transmission rate.
