To provide a method and a device which control signal power in a radio communication system.
An Eb/N0 detector 330 measures the quality measured value (Eb/N0) of a signal received by a receiver 320 in the base station 210 of the radio communication system, a processor 350 calculates an effective signal quality measured value for a certain time length, a 1st comparator 360 compares a model target signal quality measured value with the effective signal quality measured value, and an aggregating device 370 increases a target quality measured value only by one step-up size, when the effective signal quality measured value is smaller than the model target quality measured value or reduces the target quality measured value only by one step-down size, when the effective quality measured value is larger than the model target quality measured value to adjust the target signal quality measured value, while corresponding to a fact that the effective signal quality measured value is different from the model target signal quality measured value. A 2nd comparator compares the target signal quality measured value with a received signal quality measured value and sends the adjustment request of the signal power from a mobile terminal to the mobile terminal.
