Abstract
A method reduces channel interference in a communication system that includes base stations and terminal stations with each base station having a plurality of sectors, each sector having a channel, and with each terminal station associated with a sector of a base station. A first set of terminal stations associated with a first sector that may potentially interfere with a second set of terminal stations associated with a second sector is determined. A first frequency sub-channel for use by the first set of terminal stations is selected and a second frequency sub-channel for use by the second set of terminal stations is selected. Transmissions by the first set of terminal stations are coordinated with transmissions by the second set of terminal stations, thereby reducing channel interference between the terminal stations of the first set and the terminal stations of the second set, as seen by a base station in the first or second sector.
