Abstract: In order to solve a problem in which when a terminal is converted from an active state of transmitting data to an inactive state, the transmission power of the terminal rapidly increases, a base station can control the transmission power by predicting and reflecting, in a target SIR, a decrease in SIR which results from an increase in interference amount due to data transmission of another terminal. The present invention can ensure the quality of an uplink control channel by controlling power in consideration of the effect of interference, even when the terminal is in an inactive state.
