Abstract:
1. A transmission apparatus comprising: a spreading section configured to spread transmission data by discrete Fourier transform to generate a first multi-carrier signal in each of a plurality of frequency channels; a data selection section configured to select, based on control information, one of the first multi-carrier signal and a second multi-carrier signal that is not spread by the spreading section; a sub-carrier allocation section configured to allocate the first multi-carrier signal to a plurality of sub-carriers using one of a first manner and a second manner in each of the plurality of frequency channels which the first manner being a manner for non-continuously allocating the plurality of sub-carriers in at least a first group and a second group where the first group includes a first portion of the plurality of sub-carriers continuously allocated to form the first group and where the second group includes a second portion of the plurality of sub-carriers continuously allocated to form the second group, and the second manner being a manner for allocating the plurality of sub-carriers continuous to form a single group of sub-carriers, in a case that the data selection section selected the first multi-carrier signal; and an Radio Frequency (RF) section configured to transmit the first multi-carrier signal simultaneously from each of the plurality of frequency channels.
