<p>To improve precision of control of data transmission. A processing part (22) transmits, from at least one of a plurality of antennas (12), data associated with each of the antennas (12). A control part (30) generates a request signal for causing a second radio apparatus to provide rate information of the second radio apparatus. When transmitting the request signal, the processing part (22) also transmits, from a plurality of antennas (12) also including ones other than an antenna (12) from which to transmit the data, known signals associated with the respective antennas (12).</p> |
