摘要 |
A transmission apparatus for transmitting an uplink control signal by using a predetermined number of basic frequency blocks in 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, includes: 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; 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. 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. |
