Abstract
An apparatus for transmitting data in a communication system includes: a receiving unit configured to receive feedback information for each of a plurality of stations (STAB) in response to a control frame; an adjusting unit configured to adjust links of the STAB at frequency channels based on the feedback information, and set optimal links for the respective STAB; and a transmitting unit configured to transmit data to the STAB through the optimal links, wherein the feedback information comprises one or more of optimal stream number information, optimal modulation and coding scheme (MCS) information, optimal bandwidth information, average signal-to-noise ratio (SNR) information, space-time information, optimal space-time block coding (STBC) information, group ID information, coding type information, and FB Tx type information.
