Patent ID: 8144657

Claim:
A method for allocating resource blocks in an orthogonal frequency-division multiple access network, including a set of base stations and a set of mobile stations served by each base station in a cell, and each cell is partitioned into a set of sectors, and each cell includes a center zone, an edge zone and a corner zone, comprises the steps of: forming clusters from the sectors, wherein each cluster includes adjacent sectors from different neighboring cells; acquiring channel state information collection for each cluster in one of the base stations associated with the cluster; and allocating resources for each mobile stations in each cluster according to whether the mobile station is the center zone, the edge zone or the corner zone of the cell, and wherein the allocating uses the channel state information for the cluster, wherein the allocating uses proportional fair scheduling to provide similar transmit data rates for the mobile stations and wherein the proportional fair scheduling for each mobile station u is ρ u = mr u R u , where m is a number of resource blocks allocated to the mobile station u in a current frame, r u is a data rate is used according to the channel state information, and R u is the data rate of a previous frames.
