Abstract
Provided is a radio communication device which can prevent interference between SRS and PUCCH when the PUCCH transmission bandwidth fluctuates and suppress degradation of CQI estimation accuracy by the band where no SRS is transmitted. The device includes: an SRS code generation unit () which generates an SRS (Sounding Reference Signal) for measuring uplink line data channel quality; an SRS arrangement unit () which frequency-multiplexes the SRS on the SR transmission band and arranges it; and an SRS arrangement control unit () which controls SRS frequency multiplex so as to be uniform in frequency without modifying the bandwidth of one SRS multiplex unit in accordance with the fluctuation of the reference signal transmission bandwidth according to the SRS arrangement information transmitted from the base station and furthermore controls the transmission interval of the frequency-multiplexed SRS.
