PROBLEM TO BE SOLVED: To prevent degradation of utilization efficiency of a communication resource of a channel for performing frequency diversity transmission at the time when both frequency scheduling transmission and the frequency diversity transmission are performed simultaneously in multicarrier communication.SOLUTION: A modulation part 12 performs a modulation process on Dch data after encoding, to generates Dch data symbol. A modulation part 22 performs a modulation process on Lch data after encoding, to generates Lch data symbol. An allocation part 103 allocates the Dch data symbol and the Lch data symbol to each subcarrier constituting an OFDM symbol, and outputs them to a multiplex part 104. In this case, if the allocation part 103 uses a plurality of Dchs for the Dch data symbol of one mobile station, Dchs of consecutive channel numbers are employed. |
