Abstract:
1. A transmission apparatus for transmitting an uplink signal by using a plurality of basic frequency blocks, wherein a system band is divided into a plurality of bands by a basic frequency block having a predetermined bandwidth, comprising: a mapping unit configured to map control information to subcarriers in a basic frequency block in a given subframe; an inverse Fourier transform unit configured to perform inverse Fourier transform on a signal to which the control information is mapped by the mapping unit; and a radio transmission unit configured to transmit a transmission signal, to a receiving apparatus by radio, including a signal on which inverse Fourier transform has been performed by the inverse Fourier transform unit, wherein, in a subframe subsequent to the given subframe, the mapping unit maps the control information to subcarriers in a basic frequency block of a band different from a band of the basic frequency block in the given subframe, wherein, in a basic frequency block in a given subframe, the mapping unit maps the control information to a plurality of bands that are prepared discontinuously in the frequency domain over a period of a subframe and that are prepared separately from a band for a shared data channel.
