Patent ID: 7764662

Claim:
A method for allocating frequency resources in a serving cell in a multicell communication system including a plurality of cells, the method comprising the steps of: dividing, by a controller, a frequency band used in the multicell communication system into a plurality of segment bands; dividing, by the controller, the frequency band into a plurality of band groups by mapping the plurality of segment bands such that at least one segment band among the plurality of segment bands is allocated to a band group; mapping, by the controller, the plurality of band groups such that a first band group is allocated to a center band of the serving cell; mapping, by the controller, the plurality of band groups such that remaining band groups other than the first band group among the plurality of band groups are allocated to reuse bands; allocating, by the controller, a plurality of band groups to be used for transmitting user data for each of a plurality of subscriber stations among the plurality of band groups if there is user data targeting the plurality of subscriber stations; allocating, by a band group allocator, the user data for each of the subscriber stations such that the user data is transmitted through a corresponding band group; allocating, by an segment allocator, segment bands of the plurality of band groups allocated such that the user data for each of the subscriber stations is transmitted; RF-processing, by a RF processor, a signal of the segment-allocated band groups; and transmitting the RF-processed signal, wherein the first band group is mapped such that it is allocated to center bands of cells spaced apart by a predetermined distance from the serving cell among remaining cells other than the serving cell among the plurality of cells.
