Abstract

A method and system for fractional frequency reuse in a communication network. A plurality of fractional frequency reuse modes for wireless communication are defined in which each of the modes are associated with a corresponding group of wireless communication tones assigned to one of a plurality of power levels. Communication with at least one mobile terminal in a first region is established using a fractional frequency reuse mode from the plurality of fractional frequency reuse modes. A coverage problem with communication with at least one of the mobile terminal in the first sector is detected. A base station associated with a second region is notified to change communication within the second region to a different fractional frequency reuse mode from the plurality of fractional frequency reuse modes.
