Abstract
Provided is, in wireless communication systems such as TD-LTE where there might be difference in frequency band allocated to a mobile station between uplink and downlink, a wireless communication system which is capable of ensuring desired antenna directivity by the mobile station controlling an adaptive array antenna, such a method for controlling a wireless communication system, such a base station, and such a mobile station. The mobile station transmits to the base station a message indicating that the self station includes an adaptive array antenna. Upon receiving the message, the base station assigns a downlink resource block and an uplink resource block following the downlink resource block allocated to the mobile station within the same frequency band. The mobile station 1 controls the adaptive array antenna based on a signal received using the allocated downlink resource block and transmits a signal using the allocated uplink resource block.
