Abstract

Base station 20, mobile terminal device 30 the result of monitoring the changes in the parameters of the adaptive array antenna to control the directivity of the beam to be transmitted, if the value indicating the change falls below a predetermined value, the signal to be transmitted inhibit control of directivity. Further, the base station 20 transmits the decrease information indicating that the value indicating the change falls below a predetermined value to the mobile terminal device 30. Mobile terminal device 30, when receiving the decrease information transmitted from the base station 20, based on the delay status of the reception signal received from the base station 20, to equalize the signal to be transmitted to the base station 20, and the equalized signal and it transmits to the base station 20.
