Abstract
The present invention provides method and system for managing communication in a Frequency Division Multiple Access (FDMA) communication network. The method comprises reserving a first segment downlink time slot and/or a first segment uplink time slot for a first segment in the FDMA communication network. The first segment belongs to a plurality of segments used in the FDMA communication network. Thereafter, a communication is scheduled between a base station and one or more mobile stations based on the first segment downlink time slot and/or the first segment uplink time slot. The base station uses the first segment at a high power level for the communication. Further, the one or more mobile stations can be scheduled for an uplink transmission, based on a location of the one or more mobile stations. A mobile station can be located in one of a plurality of sectors of a cell area of a base station.
