摘要： A relay communication method in an orthogonal frequency division multiple access (OFDMA) communication system including at least one base station for providing a multiple access service to a plurality of mobile stations frame by frame. The relay communication method includes dividing a cell defined by transmission power of the base station into a plurality of sectors on the basis of the base station; dividing the cell into an inner area where a first service is supported and an outer area where a second service is supported, on the basis of the base station; arranging at least one relay station in a second service area of each sector; and allocating a partial resource of the frame for communication between the base station and the mobile station through the relay station.

A full subcarrier band allocable for one cell is divided into a plurality of subcarrier regions. Subcarriers selected from subcarriers existing in one of the plurality of subcarrier regions are allocated for each of a plurality of sectors constituting the cell. The subcarriers are allocated such that subcarriers existing in different subcarrier regions are allocated for neighboring sectors in the cell.
