In a transmission power control method, a base station apparatus and a communication terminal, transmission between the transmission side and the reception side can be preformed with an optimum transmission power. In the transmission power control method in which at the transmission side, a control signal for controlling the transmission power is transmitted, while at the reception side, the transmission power is controlled based on the received control signal, with the power value of the transmission power having reached the limit value of a power control range, if the instructions of the received control signal are to control the power value in the direction of allowing it to exceed the power control range, the number of receptions of the control signal is counted, and if the instructions of the control signal received thereafter are to control the power value in the direction of not allowing it to exceed the power control range, the count value of the number of receptions is decreased, and the power value is not controlled in the direction of not allowing it to exceed the power control range until the count value reaches a predetermined value.
