<P>PROBLEM TO BE SOLVED: To prevent deterioration of utilization efficiency of a communication resource for a channel for effecting frequency diversity transmission upon effecting frequency scheduling transmission and the frequency diversity transmission simultaneously in a multi-carrier communication. <P>SOLUTION: A modulation unit 12 produces a Dch (distributed virtual resource block) data symbol to a Dch data after encoding. Another modulation unit 22 produces an Lch data symbol by effecting modulation treatment to an Lch (localized virtual resource block) data after encoding. An allocation unit 103 allocates the Dch data symbol and the Lch data symbol to respective sub carriers which constitute OFDM (orthogonal frequency division) symbols to output the same to a multiplex unit 104. In this case, the allocation unit 103 employs Dchs of continuous channel numbers in a case when a plurality of Dchs are employed for the Dch data symbol of one mobile station. <P>COPYRIGHT: (C)2011,JPO&INPIT |
