US 2006/0140217 A1 · Method for adaptively allocating frequency resource in communication system using orthogonal frequency division multiple access scheme

Abstract

Disclosed is a method for adaptively allocating frequency resources in a communication system using an orthogonal frequency division multiple access scheme. The method for allocating frequency resources in the communication system that includes a plurality of cells using an identical frequency band includes the steps of dividing a frequency band used in the communication system into sub-frequency bands corresponding to a number of cells, and allocating one of the sub-frequency bands to each of mobile subscriber stations exiting in the cells according to positions of the mobile subscriber stations, thereby increasing the degree of the freedom for frequency resource allocation and minimizing ICI.

Dependent claims

A method for adaptively allocating frequency resources in a communication system using an orthogonal frequency division multiple access (OFDMA) scheme, the method comprising the steps of:

dividing a cell into a plurality of sub-cells corresponding to positions of mobile subscriber stations (MSS) existing in the cell;
dividing a frequency band used in the communication system into sub-frequency bands corresponding to the number of sub-cells;
and
allocating the sub-frequency bands to the sub-cells in such a manner that the sub-cells corresponds to the sub-frequency bands in a ratio of 1:1.
