MOBILE STATION APPARATUS AND DATA RECEIVING METHOD

摘要

PROBLEM TO BE SOLVED: To prevent the decline of a system throughput due to the degradation in a utilization efficiency of a communication resource of a channel for carrying out a frequency diversity transmission when a frequency scheduling transmission and a frequency diversity transmission are concurrently carried out in multiple carrier communication.

SOLUTION: A modulation part (12) carries out modulation processing for Dch data after coding to generate a Dch data symbol. A modulation part (22) carries out modulation processing for Lch data after coding to generate an Lch data symbol. An allocation part (103) allocates the Dch data symbol and the Lch data symbol to each sub-carrier composing an OFDM symbol and outputs the allocated sub-carrier to a multiplex part (104). In this case, the allocation part (103) allocates the Dch data symbol to a plurality of resource blocks where one Dch is arranged at an interval equal to integral multiples of the number of resource blocks composing a resource block group.
