<p><P>PROBLEM TO BE SOLVED: To effectively evaluate transmission line properties by efficiently utilizing a combination in which signals are to be made orthogonal using limited frequencies or codes. <P>SOLUTION: When transmitting sounding reference signals (SRSs), each of which becomes the base of CSI measurement, from two antennas 81, 82 in a base station device, a control section 100 controls resource element mapper sections 51 and 52 in accordance with the use of CSI in the base station device and makes the signals orthogonal using frequencies or codes between the two antennas 81, 82 or sets the signals to the equal frequency and code. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
