Abstract: A multicell communication system includes a plurality of cells which use a frequency band on a division basis, wherein a frequency reuse factor K is defined such that the frequency band is divided into K sub-frequency bands, the K sub-frequency bands are allocated to K cells including a serving cell among the plurality of cells, and the K sub-frequency bands are reused in some of the remaining cells other than the K cells, and the K cells use the frequency band on a division basis. The frequency band is divided into a plurality of segment bands. The plurality of segment bands is mapped such that at least one of the segment bands is allocated to each of the band groups, to divide the frequency band into the K band groups.

Abstract: A method for using resources in a multi-cell communication system is disclosed. The method includes dividing a frequency band used in the multi-cell communication system into a plurality of unit subchannels; and allocating the unit subchannels according to a sequence which is predefined in each cell in an allocation order of the unit subchannels depending on identifier information of the multiple cells.

Abstract: A method is provided for controlling resource allocation in a multicell communication system including a plurality of cells, each of the cells using the same frequency band. The method comprises dividing the frequency band for each of the cells into a plurality of band groups; dividing a cell region for each of the cells into a plurality of segment regions; and mapping corresponding segment regions to each of the band groups.
