<P>PROBLEM TO BE SOLVED: To suppress degradation of CQI estimation accuracy on bands on which an SRS is not transmitted while preventing interference between the SRS and a PUCCH when the PUCCH transmission bandwidth fluctuates. <P>SOLUTION: Provided is a wireless communication device capable of suppressing degradation of CQI estimation accuracy on bands on which a SRS is not transmitted while preventing interference between the SRS and a PUCCH when the PUCCH transmission bandwidth fluctuates. In the device, an SRS code generation unit (201) generates an SRS(Sounding Reference Signal) for measuring the quality of an uplink data channel, an SRS arrangement unit (202) frequency-multiplexes and arranges the SRS on an SRS transmission band, and an SRS arrangement control unit (208), based on SRS arrangement information transmitted from a base station, according to the fluctuation of a reference signal transmission bandwidth, without changing the bandwidth of one multiple unit of the SRS, controls the frequency multiplex of the SRS so that the SRS is equalized in frequency, and controls transmission intervals of the frequency multiplexed SRS. <P>COPYRIGHT: (C)2012,JPO&INPIT |
