ABSTRACT:
A transmission power control method that is able to keep the signal quality approximately constant. A receiving-side station measures the average CIR for the radio communication channel in use. The receiving side station delivers a command for decreasing the transmission power to a transmitting-side station when the measured value is equal to or greater than a reference value. The receiving-side station also delivers a command for increasing the transmission power to the transmitting-side station when the measured value is less than the reference value. When a command for a preceding control period is an increase command, the transmitting power for the next control period is set as a first value obtained by subtracting a predetermined value from a prior value that precedes by the delay time. When the command for a preceding control period is a decrease command, and the sum period is not longer than the delay time, the transmitting power is set as a second value, which is a lower one of the first value and the preceding value. When the command for a preceding control period is a decrease command, and the sum period of the prior successive decrease commands is longer than the delay time, the transmitting power is set as a third value obtained by subtracting the predetermined value from the preceding value. When the detected command is the increase command, the power is set as a value in a similar way.
