in a method of fractional frequency reuse in a communication network , a frequency band is divided into a plurality of sub - bands according to a fractional frequency reuse scheme to define a ffr allocation of the band for a plurality of bases stations , each of the base stations being associated with a respective region . at a first base station of the plurality of base stations , the first base station associated with a first region , communication with a mobile terminal in the first region is established on one of the plurality of sub - bands according to the ffr allocation . a second base station of the plurality of base stations , the second base station associated with a second region , transmits on the one of the plurality of sub - bands according to the ffr allocation ; receives an indication of a coverage problem detected at the mobile terminal due to interference from the second base station on the one of the plurality of sub - bands ; and in response to the receiving the indication , decreases a transmit power level for the one of the plurality of sub - bands in the second region .
