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. The K band groups is mapped such that a first band group which is a particular one of the K band groups is allocated to a center band, and the K band groups are mapped such that the remaining band groups other than the first band group among the K band groups are allocated to reuse band groups.
