Wireless communication apparatus and wireless communication method

A wireless communication method for controlling wireless communication between a wireless communication apparatus having a plurality of antennas and a counterpart wireless communication apparatus, comprising:

• a reception channel coefficient calculation step for calculating a reception channel coefficient in a reception frequency band, for each of the plurality of antennas;
• a transmission channel coefficient calculation step for calculating a transmission channel coefficient in a transmission frequency band, for each of the plurality of antennas, by extrapolation based on a distribution of reception channel coefficients calculated at the reception channel coefficient calculation step in a direction of frequency;
• and
• a correction step, when an absolute value of the transmission channel coefficient is greater than a threshold calculated based on the reception channel coefficient, for correcting the transmission channel coefficient calculated at the transmission channel coefficient calculation step such that the absolute value is matched with the threshold.
