FIELD: information technology.
SUBSTANCE: transmitter station receives channel information for at least one subcarrier which is a subset of multiple subcarriers used to transmit data. Channel information can include at least one transmission control matrix, at least one set of eigen vectors, at least one channel response matrix, at least one channel covariance matrix, uncontrolled pilot signal or a controlled pilot signal for at least one subcarrier. The transmitter station receives at least one transmission control matrix for at least one subcarrier from the channel information and determines the transmission control matrix for each of the multiple subcarriers. The transmitter station controls transmission or controls the position of the directional pattern for each of the multiple subcarriers with the transmission control matrix for such subcarrier.
EFFECT: high carrying capacity of MIMO channel and improved reliability.
