    摘要: A communication control method is applied to a mobile communication system including a base station that transmits a downlink signal through a plurality of antenna ports, and a user terminal that feeds back precoder matrix information to the base station, the downlink signal being precoded by using a precoder matrix, the precoder matrix information being indicating a precoder matrix preferably used in a downlink. The communication control method comprises: a step of feeding back, by the user terminal, correction value information for correcting the precoder matrix information to the base station when the precoder matrix information is fed back or after the precoder matrix information is fed back.

    摘要: A method for providing precoding weights for data symbols of data control subframes includes generating a downlink frame having control subframes which individually correspond to one of a plurality of downlink data subframes, and inserting weight information into each of the control subframes, such that the weight information is to be applied to data symbols present in the corresponding one of the data subframes. The method further includes transmitting the control subframes and the inserted weight information to a receiving device.
