    摘要: A method for transmitting data in an Orthogonal Frequency Division Multiple Access (OFDMA) system. The data transmission method includes determining a number of diversity tiles, each of which includes physically separated frequency resources; dividing an entire system band into diversity subbands including the diversity tiles and localized subbands including localized tiles, each of which includes physically adjacent frequency resources, when the determined number of diversity tiles is greater than a threshold; uniformly distributing the diversity tiles over the entire system band, and disposing the localized tiles in the remaining bands except for the diversity tiles, when the determined number of diversity tiles is not greater than the threshold; and transmitting data to multiple terminals over the configured diversity tiles and localized tiles using diversity transmission and localized transmission schemes.
