Patent ID: 7746839

Claim:
A method of managing communication in an orthogonal frequency division multiple access (OFDMA) system, the method comprising: setting use of at least a first segment belonging to a plurality of segments of an OFDMA frame as a high power segment for a plurality of base stations to communicate with at least one first communication device in the OFDMA system; determining if the at least one first communication device is present in one of a first area and a second area of each of the plurality of base stations, the first area and the second area belonging to a cell area of each of the plurality of base stations; if the at least one first communication device is present in the first area, facilitating the each of the of the plurality of base stations to communicate with the at least one first communication device using at least one or more segments belonging to the plurality of segments, wherein the at least one or more segments have a lower power than the first segment; and if the at least one first communication device is present in the second area, assigning each region of a first plurality of regions belonging to the first segment to at least one set of base stations, wherein the at least one set of base stations belongs to the plurality of base stations, and wherein the at least one first communication device is located in a cell area of the at least one set of base stations; and using at least an assigned region of the first segment for a communication between the at least one set of base stations and the at least one first communication device, wherein the communication being a unicast communication.
