1. A radio communication method by a radio communication system in which output signals are generated from a plurality of information signals and then transmitted respectively at a plurality of different frequencies to a system of a communication partner from N antennas, the method comprising:

  • receiving control information by a control signal which is transmitted by the system of the communication partner; and

    transmitting transmission signals respectively at the plurality of frequencies from the N antennas based on the received control information, the transmission signals each being generated based on a first operation result, which is obtained by multiplying a first information signal by a first N-dimensional weight vector, and a second operation result, which is obtained by multiplying a second information signal by a second N-dimensional weight vector, whereinthe control information includes weight-related information representing a set of the first N-dimensional weight vector and the second N-dimensional weight vector,the first information signal and the second information signal include a set of signals modulated and encoded individually, andthe weight-related information is common to all of the plurality of frequencies used for signal transmission from the radio communication system to the system of the communication partner.
