Abstract
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 (φ) and a precoding matrix (φinv) orthogonal to the precoding matrix (φ). A control unit (106) controls the interval for using the precoding matrix (φinv) independently of the interval for using the precoding matrix (φ).
