ABSTRACT:
In a mobile communication system100of the third generation CDMA type. A base station control apparatus1controls a transmission power of an opponent communication apparatus by means of measuring a FER within a predetermined segment, averaging plural pieces of quality information per frame, producing a translation table40cby means of associating the FER acquired by the measurement and average frame quality information acquired by the averaging, estimating an estimated FER corresponding to the quality information per frame from the translation table40c, and controlling a target receive power threshold based on the estimated FER and a target FER stored in advance, thereby quickly carrying out the transmission power control, improving the data quality of a lower layer, maintaining the data quality as constant, and increasing the throughput.
