Abstract
Abstract A method for interference control includes receiving at a base station an interference report from a neighbor base station. The interference report indicates interference observed at the neighbor base station. The method also includes regulating, by the base station, data transmissions for terminals based on the interference report received from the neighbor base station. Regulating the data transmissions includes identifying disadvantaged terminals and assigning the disadvantaged terminals with lower data rates.
