WIRELESS COMMUNICATION MOBILE STATION DEVICE AND METHOD FOR USING PRECODING MATRIX
摘要
<p>Provided is a wireless communication mobile station device capable of suppressing an increase in an SRS resource even when the mobile station is provided with a plurality of antennas. In the device, a weighting section (115) weights transmission data inputted from an IFFT section (111) and an SRS inputted from an IFFT section (114) by using a precoding matrix (?) and a precoding matrix (?inv) orthogonal to the precoding matrix (?). A control unit (106) controls the interval for using the precoding matrix (?inv) independently of the interval for using the precoding matrix (?).</p>
