When the SIR of the received signal is larger than the SIR upper limit, threshold determining section (105) outputs an instruction for decreasing the transmit power to control bit generating section (106). Further, when the SIR is smaller than the SIR lower limit, threshold determining section (105) outputs an instruction for increasing the transmit power to control bit generating section (106). When the SIR of the received signal is equal to or smaller than the SIR upper limit and equal to or larger than the SIR lower limit, threshold determining section (105) outputs the determined result to control bit generating section (106), which refers to a last instruction on the transmit power control stored in storage section (107), and outputs an instruction opposite to the last instruction with respect to an increase or decrease in the transmit power to storage section (107) and multiplexing section (108). |
