There is provided a transmission power control method for a terminal. In this method, when reception power is divided into at least two ranks at equal intervals, each of the at least two ranks has an allowable range having an identical size, a margin is set between a lower limit of the allowable range in an upper rank and an upper limit of the allowable range in a lower rank in the at least two ranks, and the allowable range is equal to or larger than the margin, the terminal adjusts transmission power of the first signal and the second signal by using a transmission power adjustment amount calculated by using reception power of the first signal and the second signal, a reception power difference between these signals, the at least two ranks, the allowable range, and the margin.
