Abstract
To provide a radio communication method for enabling a control signal to be received with high quality and high efficiency, in the case of using spatial multiplexing transmission in data signals to transmit, and also transmitting the control signal in the same sub-frame, in the radio communication method of the invention, a mobile terminal apparatus receives a downlink signal including precoding information, separates a data signal and a control signal to assign to different radio resources, and performs MIMO-transmission on a signal of each transmission layer based on the precoding information, and a radio base station apparatus receives an uplink signal including the data signal and the control signal subjected to MIMO transmission, divides the uplink signal into data signals for each transmission layer, and reproduces the control signal from the uplink signal.
