Abstract:
1. A transmission apparatus comprising: a multiplexing portion that multiplexes a common pilot channel, a shared control channel, and a shared data channel; a symbol generation portion that performs an inverse Fourier transformation on the multiplexed signal so as to generate a symbol; and a transmission portion that transmits the generated symbol; wherein the multiplexing portion multiplexes the shared control channel including control information necessary for demodulation of the shared data channel including a payload and the common pilot channel to be used by plural users in either one of a frequency direction and a time direction, or a combination thereof, and multiplexes the shared data channel in a time direction with respect to the common pilot channel and the shared control channel, wherein the multiplexing portion multiplexes a dedicated pilot channel used to demodulate the shared data channel with the shared data channel allocated to a specific user in either one of the frequency direction and the time direction, or a combination thereof, and wherein the dedicated pilot channel is time-multiplexed at a first point of time at predetermined frequency intervals and also time-multiplexed at a second point of time at the predetermined frequency intervals.
