A radio communication terminal includes a detection unit configured to detect a plurality of usable frequencies of a frequency range, in which the radio communication terminal plans to transmit, at least depending on whether or not a power of a first received signal is greater than a first threshold, a selection unit configured to select, when a first frequency band from f0+f1 to f0+f1+Deltaf1 (f1 is a first frequency, and Deltaf1 is a first bandwidth) and a second frequency band from f0-f1-Deltaf1 to f0-f1 are simultaneously usable with respect to a center frequency f0 of a utilizing frequency range including the usable frequencies, the first frequency band and the second frequency band as a pair of utilizing frequency bands, and a transmission unit configured to transmit different signals in the pair of utilizing frequency bands.
