    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.

    摘要: A transmission/reception apparatus for transmitting packet data in an Orthogonal Frequency Division Multiplexing (OFDM) system. The apparatus includes a transmission module for generating a frame of an OFDM symbol including pilot tones using the packet data, and transmitting the frame to a wireless network; and a controller for changing at least one of a Pilot-to-Data Ratio (PDR) of the pilot tones and a density of the pilot tones based on a length of the frame. The reception apparatus includes a reception module for receiving a frame of an OFDM symbol including pilot tones from a wireless network, extracting the pilot tone from the received frame, performing channel estimation thereon, and demodulating the packet data; and a controller for receiving at least one of a PDR of the pilot tone and a density of the pilot tone, both of which are in proportion to a length of the frame, and controlling the reception module so that the channel estimation is performed, based on the received information.
