Abstract
A control information transmitting method for controlling transmission power, wherein a control symbol obtained by assigning control information for controlling transmission power to symbols of phase modulation is transmitted to a communication partner so as to control the transmission power of the communication partner, the control information which represents raising the transmission power of communication partner and the control information which represents lowering the transmission power of the communication partner are assigned to a pair of symbols having the longest Euclidian distance among the symbols of phase modulation. Whereby, even if receiving noise or interference are present during transmission, the control information can be prevented from being misjudged because the distance on the signal constellation is farthest apart from each other, so that the control information can be transmitted exactly.
