Patent ID: 8078185

Claim:
A method, comprising: partitioning, by a base station, a designated frequency band into a plurality of sub-bands, wherein each sub-band is assigned a reuse factor and a power level, wherein the frequency band is used for communication between the base station and one or more subscriber stations in a cellular network; splitting, by the base station, each cell in the cellular network into at least two groups based on a degree of satisfaction metric obtained from each subscriber station, one of the groups being a cell edge user group, wherein the degree of satisfaction metric is defined relatively according to a quality of service (QoS) of each subscriber station in the cellular network and the subscriber stations occupying the at least two groups are adjusted dynamically by the base station according to changes in the QoS of each subscriber; based on the at least two user groups, calculating, by the base station, a number of available resource units for each user group, wherein the number of available resource units for each user group is proportional to the number of subscriber stations in the user group; and scheduling, by the base station, the cell edge user group before another user group of the at least two user groups using a best resource unit of the available number of resource units, subscribers in the cell edge user group to be assigned, by the base station, a boosted sub-band of the plurality of sub-bands, wherein the boosted sub-band has a reuse of greater than one and less than three; wherein the interference to cells in the cell edge user group is mitigated; creating a feedback pattern matrix to be populated with channel quality indicator information of the first sub-band, the second sub-band, and the third sub-band, the feedback pattern matrix comprising a first column for the cell edge user group, a second column for a cell middle user group, and a third column for a cell center user group, a first row for the first sub-band, a second row for the second sub-band, and a third row for the third sub-band; broadcasting the feedback pattern matrix to subscriber stations in the cellular network; and populating the feedback pattern matrix with channel quality indicator (CQI) information fed back from one or more subscriber stations located in each user group, wherein the CQI information is disposed in the feedback pattern matrix based on the location and sub-band assignment of the subscriber station; wherein the CQI information in the feedback pattern matrix is used to allocate resource units to each subscriber station in each user group.
