PROBLEM TO BE SOLVED: To provide a wireless communication method whereby a range of eliminating interference components performed from partial transfer function matrices of wireless terminal stations is limited to a necessity minimum range in the transmission directivity control for the multiuser MIMO communication. SOLUTION: The wireless communication method adopted by a method of the MIMO communication between a first wireless station and a plurality of second wireless stations, acquires transfer functions between the first wireless station and the second wireless stations, selects the second wireless stations for communication opposite parties, extracts a first transfer function matrix resulting from transfer functions between the first wireless station and the second wireless stations, obtains a basic vector in a partial space stretched by row vectors of the second transfer function matrix by the transfer functions between the first wireless station and the second wireless stations other than the noted second wireless stations, obtains a coefficient from a mapped amount to the calculated basic vector, cancels components by multiplying a coefficient with each component in a basic vector direction by each row vector of the first transfer function matrix, and acquires a transmission weight matrix by the basic vector of the partial space stretched by the calculated row vectors.
