Provided is a wireless communication apparatus by which the maximum throughput can be obtained while satisfying required reception qualities in multicarrier communication. In the apparatus, a coding section (101) performs error correction coding to all of the plurality of resource blocks at a same coding rate, modulating sections (103-1 to 103-n) generate data symbols by modulating coding data for each of the resource blocks (1 to n), and repetition sections (104-1 to 104-n) repeat the data symbols inputted from the modulation section (103) for each of the resource blocks (1 to n) to generate a plurality of same data symbols. Namely, while the coding rate is same in all of the resource blocks, modulation system and the number of repetitions differ by resource block.
