Wireless communication system, method for controlling wireless communication system, base station, and mobile station

In a wireless communication system which includes a mobile station and a base station and in which there might be a difference in a frequency band between a downlink resource and an uplink resource allocated to the mobile station, the base station comprising:

• a communicator that receives from the mobile station a message indicating that the mobile station includes the adaptive array antenna;
• and
• a controller that, in response to receiving the message, assigns the same frequency band as a frequency band of a downlink resource block to be a frequency band of an uplink resource block following the downlink resource block, the downlink resource block and the uplink resource block being allocated to the mobile station.

In a wireless communication system which includes a mobile station and a base station and in which there might be a difference in a frequency band between a downlink resource and an uplink resource allocated to the mobile station, the mobile station comprising:

• a communicator that transmits to the base station a message indicating that the mobile station includes the adaptive array antenna;
• and
• a controller that calculates an antenna weight based on a reception signal received by using a downlink resource block allocated by the base station in response to the message and that controls the communicator to transmit a transmission signal by using an uplink resource block allocated by the base station, the allocated uplink resource block following the allocated downlink resource block and being assigned with a frequency band that is the same frequency band as a frequency band of the allocated downlink resource block.
