ABSTRACT:
In a transmission power control method, a receiver receives user data transmitted intermittently from a transmitter to a receiver and control data transmitted continuously from the transmitter to a plurality of receivers including the receiver via a DPDCH and a CPICH, respectively; and generates, when the receiver is receiving the user data from the transmitter via the DPDCH, a command for controlling transmission power of the transmitter of a DPDCH in a manner that an SIR of a received signal of the DPDCH by the receiver becomes equal to a target SIR, and generates, when the receiver is not receiving the user data from the transmitter via the DPDCH, a command for controlling the transmission power of the transmitter of the DPDCH by updating the target SIR by using received quality of the CPICH.
