Abstract:
1. An apparatus for transmitting data in a communication system, comprising: a receiving unit configured to receive first feedback information for a first station (STA) of a plurality of stations (STAs) and to receive second feedback information for a second STA of the plurality of STAs; an adjusting unit configured to adjust links of the first STA at frequency channels based on the first feedback information and the second feedback information, adjust links of the second STA at frequency channels based on the first feedback information and the second feedback information, and set optimal links for the respective STAs; and a transmitting unit configured to transmit data to the STAs through the optimal links, wherein the each of the first and second 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 (STEC) information, group ID information, coding type information, and Feedback Transmission (FB Tx) type information.
