Transmission method and radio apparatus utilizing the transmission method

A radio apparatus, including:

• a computing unit which computes a received response vector of a terminal apparatus which is a targeted communication party, based on signals received from the targeted terminal apparatus;
• an acquiring unit which acquires a virtual response vector of a virtual terminal apparatus different from the targeted terminal apparatus;
• a generator which generates a transmission weight vector based on the received response vector computed by said computing unit and the virtual response vector acquired by said acquiring unit;
• and
• a transmitter which transmits a predetermined signal to the targeted terminal apparatus based on the transmission weight vector generated by said generator,
• wherein said acquiring unit acquires again, as appropriate, a virtual response vectors and the thus reacquired virtual response vector is again subject to the processings by said generator and said transmitter.

A transmission method, including:

• computing a received response vector of a terminal apparatus which is a targeted communication party, based on signals received from the targeted terminal apparatus;
• acquiring a virtual response vector of a virtual terminal apparatus which is not the targeted terminal apparatus;
• generating a transmission weight vector based on the received response vector computed in said computing and the virtual response vector acquired in said acquiring;
• and
• transmitting a predetermined signal to the targeted terminal apparatus based on the transmission weight vector generated by said generating,
• wherein said acquiring a virtual response vector is such that a virtual response vector is acquired again, as appropriate, and the thus reacquired virtual response vector is again subject to the processings by said generating a transmission weight vector and said transmitting a predetermined signal.

A program executable by a computer, the program including the functions of:

• computing a received response vector of a terminal apparatus which is a targeted communication party, based on signals received from the targeted terminal apparatus;
• acquiring a virtual response vector of a virtual terminal apparatus different which is not the targeted terminal apparatus;
• generating a transmission weight vector based on the received response vector computed in said computing and the virtual response vector acquired in said acquiring;
• and
• transmitting a predetermined signal to the targeted terminal apparatus based on the transmission weight vector generated by said generating,
• wherein said acquiring a virtual response vector is such that a virtual response vector is acquired again, as appropriate, and the thus reacquired virtual response vector is again subject to the processings by said generating a transmission weight vector and said transmitting a predetermined signal.
