Abstract:
1. A base station apparatus comprising: a mapping unit configured to map either first block(s), to which data for a mobile station are localizedly allocated, or second block(s), to which data for a mobile station are distributedly allocated, to each of a plurality of blocks, into which a plurality of consecutive subcarriers in a frequency domain are divided and each of which is comprised of the same number of subcarriers; and a transmitting unit configured to transmit control information including information indicating to the mobile station whether the first block(s) or the second block(s) are assigned to the mobile station, information indicating to the mobile station the first block(s) or the second block(s) that are allocated to the mobile station, and information indicating a modulation and coding scheme used for the data mapped to the first block(s) or the second block(s), the control information being in a format common to both the first block(s) and the second block(s), wherein the format common to both the first block(s) and the second block(s) includes a first field that indicates whether the first block(s) or the second block(s) are assigned to the mobile station, a second field that indicates the first block(s) or the second block(s) that are allocated to the mobile station, and a third field that indicates the modulation and coding scheme used for the data mapped to the first block(s) or the second block(s).
