Patent ID: 8125963

Claim:
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, wherein the control information includes weight-related information including 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 one of a set of signals modulated by different modulation schemes and a set of signals encoded by different encoding methods, and the 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.
