    • A method and an apparatus for transmitting/receiving data in an orthogonal frequency division multiple access are provided to transmit efficiently data by using a method for multiplexing and shifting the number of diversity tiles and the number of localized tiles. A decision process is performed to decide the number of diversity tiles including frequency resources from separated physically from each other(201). The decided number of diversity tiles is compared with a threshold value(203). The diversity tiles are distributed into an entire system band and localized tiles are positioned into the remaining band except for the diversity tiles when the decided number of diversity tiles is not larger than the threshold value(204). Data are transmitted through the diversity tiles and the localized tiles to a plurality of terminals by using a diversity transmission method and a localized transmission method(206,208).
