摘要： PROBLEM TO BE SOLVED: To improve reception characteristics in a signal sequence of a first channel, which includes ACK/NACK signals, a CQI (Channel Quality Indicator) signal, etc. considering characteristics that signal quality at a boundary of symbols or near a power changing point is easy to deteriorate. SOLUTION: A transmission station carries out multiplexing so that at least a part of signal sequence of a second channel in which error-resistance is high than the signal sequence of the first channel, intervenes between a block boundary of a time-multiplexing signal and the signal sequence of the first channel in a time domain. Namely, the signal sequences of respective channels are subjected to time-multiplexing so as to be positioned in order from high error-resistance of the respective signals in a direction to separate from the block boundary. Moreover, this time-multiplexing is carried out so that at least a part of the signal sequence of the second channel in which error-resistance is high than the signal sequence of the first channel, intervenes between a timing at which transmission power of the time-multiplexing signal changes and the signal sequence of the first channel in the time domain.
