Provided is a mobile station which can obtain an equivalent diversity effect in each communication scheme while keeping to an minimum the increase in the circuit scale of a mobile station even when the mobile station is compatible with a plurality of communication schemes. In a mobile station (100) which performs either single-carrier frequency-division multiple access (SC-FDMA) communication or orthogonal frequency division multiple access (OFDMA) communication, an interleaving unit (103) interleaves a plurality of resource elements, which are divided into a plurality of code blocks, in a plurality of code blocks when either SC-FDMA or OFDMA communication is performed. In addition, only when OFDMA communication is performed, a serial-to-parallel (SIP) converter (107) converts the data symbols to parallel streams and generates the OFDM symbols. A shifter (108) provides a different frequency shift to each OFDM symbol for the OFDM symbols input from the S/P converter (107), and distributes and places the plurality of resource elements of each plurality of code blocks after interleaving in the frequency domain.
