<p>The mobile communication device has multiple antennas, transmitting parts, and receiving parts. A baseband processing part of the mobile communication device transmits data signals to a base station device via a transmitting part and an antenna used for transmission of data signals selected based on received instructions from the base station device, and also transmits multiple reference signals via the multiple transmitting parts and antennas, so that the transmission frequencies of the reference signals in this instance do not overlap. The baseband processing part of the base station device transmits, to the mobile communication device, signals relating to information as to which of the antennas and transmitting parts of the mobile communication device will transmit the data signals and relating to information as to whether the multiple reference signals will be transmitted assigned to multiple transmitting parts and antennas of the mobile communication device, based on the quality of the received reference signals. In this way, deterioration of communication quality and interference caused by an increase in the number of reference signals can be limited.</p> |
