Abstract:
The method for a first base station for controlling interference between base stations in a wireless communication system according to one embodiment of the present invention comprises a step of receiving, from a second base station, fully blank subframe (FBS)-related information in which transmission power is set to zero (0) in a downlink control region and a downlink data region; and a step of transmitting resource allocation information based on the FBS-related information to a user device. The FBS-related information may be determined based on the almost blank subframe (ABS) pattern information of the second base station.
Abstract:
A method for controlling interference between a plurality of pico base stations within the coverage of a macro base station in a wireless communication system, according to one embodiment of the present invention, comprises the steps of: enabling a first pico base station to transmit information on a first subset of an ABS (almost blank subframe) pattern for measuring a downlink to user equipment on the basis of the ABS pattern of a macro base station; receiving, from the user equipment, the measurement results of the downlink in the first subset; detecting, from the measurement results of the downlink, interference from a second pico base station within the coverage of the macro base station, wherein if the interference is detected, the first pico base station can transmit, to the second pico base station, a message for requesting pairing with the macro base station with respect to the ABS pattern.
