Claim 0:
1. A wireless communication control method suppressing interference using a minimum mean square error (MMSE) weight in an environment of wireless communication where the number of transmission stations transmitting a wireless signal to a receiving station is larger than the number of reception antennas of the receiving station, the method comprising:
calculating, by the receiving station, power of an interference signal included in a signal received by the receiving station from the transmission stations the number of which is larger than the number of reception antennas, the interference signal corresponding to a part by which the number of transmission stations exceeds the number of reception antennas;
calculating, by the receiving station, an MMSE weight depending on the power of the interference signal; and
performing, by the receiving station, MMSE diversity using a recalculated MMSE weight obtained by recalculating the power of the interference signal using the MMSE weight depending on the power of the interference signal and recalculating the MMSE weight depending on the recalculated power of the interference signal.
