In this apparatus, a modulating part modulates an encoded Dch data to generate Dch data symbols. A modulating part modulates an encoded Lch data to generate Lch data symbols. An assigning part assigns the Dch and Lch data symbols to subcarriers constituting OFDM symbols and outputs them to a multiplexing part. At this moment, the assigning part assigns a set of Dch and Lch data symbols to each subcarrier for a respective subband. ## Claims ### Claim 1 A mobile station apparatus comprising: a receiving unit configured to receive data in a plurality of blocks, wherein either a first block, to which data indicated by a single resource index are localizedly allocated, or each of a plurality of second blocks, to which data indicated by the single resource index are distributedly allocated, is mapped to each of the plurality of blocks, into which a plurality of consecutive subcarriers in a frequency domain and in a subframe are divided and each of which is comprised of a same number of subcarriers, and to receive control information that is in a format common to both the first block and the plurality of second blocks, wherein the format common to both the first block and the plurality of second blocks includes a first field that indicates whether the first block or the plurality of second blocks is assigned to the mobile station apparatus, a second field that indicates the single resource index indicating data that is allocated to the mobile station apparatus, and a third field that indicates a modulation and coding scheme used for the data mapped to the first block or the plurality of second blocks, wherein the plurality of second blocks, to which the data indicated by the single resource index are allocated, are mapped to the plurality of blocks with a predetermined gap such that the data indicated by the single resource index are distributed in the frequency domain, and a resource size for the data indicated by the single resource index in the plurality of second blocks is constant regardless of variation of the predetermined gap, and wherein a plurality of data sets indicated by different resource indices are multiplexed in the plurality of second blocks, and a number of the plurality of second blocks used to transmit one of the data sets indicated by the single resource index in the subframe is the same as a number of the plurality of data sets multiplexed in one of the plurality of second blocks. ### Claim 2 (depends on 1) The mobile station apparatus according to claim 1, wherein the first block or the plurality of second blocks is variably mapped per each of the plurality of blocks. ### Claim 3 (depends on 1) The mobile station apparatus according to claim 1, wherein the first block or the plurality of second blocks is variably mapped per each subframe. ### Claim 4 (depends on 1) The mobile station apparatus according to claim 1, wherein a plurality of data sets for a plurality of different mobile stations are time-multiplexed in the plurality of second blocks. ### Claim 5 (depends on 1) The mobile station apparatus according to claim 1, wherein in the plurality of second blocks, the data indicated by the single resource index are allocated in different positions in a time domain. ### Claim 6 (depends on 1) The mobile station apparatus according to claim 1, wherein the first block is used in a frequency scheduling transmission. ### Claim 7 (depends on 1) The mobile station apparatus according to claim 1, wherein the plurality of second blocks is used in a frequency diversity transmission. ### Claim 8 (depends on 1) The mobile station according to claim 1, wherein the resource size is defined by a number of subcarriers used to transmit the data indicated by the single resource index in a subframe. ### Claim 9 (depends on 1) The mobile station apparatus according to claim 1, wherein the resource size is defined by a number of units used to transmit the data indicated by the single resource index in a subframe, wherein each unit is defined as “one subcarrier x one symbol.” ### Claim 10 (depends on 1) The mobile station apparatus according to claim 1, wherein a resource size for the data indicated by the single resource index in the first block is the same as a resource size for the data in the plurality of second blocks in a subframe. ### Claim 11 (depends on 1) The mobile station apparatus according to claim 1, further comprising a measuring unit configured to measure a reception quality for each of the plurality of blocks. ### Claim 12 A method for receiving data using a mobile station apparatus comprising: receiving data in a plurality of blocks, wherein either a first block, to which data indicated by a single resource index are localizedly allocated, or each of a plurality of second blocks, to which data indicated by the single resource index are distributedly allocated, is mapped to each of the plurality of blocks, into which a plurality of consecutive subcarriers in a frequency domain and in a subframe are divided and each of which is comprised of a same number of subcarriers;
