Radio communication device, radio communication method, and radio communication program

The present application provides a case without using the response vector of the mobile station can estimate the fading speed of the mobile station, to determine whether space division multiple access wireless communication apparatus proper. The wireless communication apparatus comprising: a fading speed estimation portion (30), a phase change amount of the weight coefficients which detects the adaptive array antenna, according to the phase change amount of the weight coefficients of the weight estimated fading speed of the wireless station; and a communication control unit (12) , based on the estimated, channel assignment with space division multiple access is controlled.
