ABSTRACT:
A processing unit transmits, from at least one of a plurality of antennas, data corresponding respectively to the plurality of antennas. A control unit generates a request signal with which to have a second radio apparatus provide information on rates at the second radio apparatus. When transmitting the request signal, the processing unit also transmits known signals corresponding respectively to the plurality of antennas, from the plurality of antennas containing an antenna to transmit data.
