Abstract
Slot quality detector 121 detects reception level, and power controller inversely corresponding to reception quality 122 outputs power control information indicative of increasing transmission power in the case where the detected reception level is higher than a threshold value and of decreasing the transmission power in the case where the detected quality is lower than the threshold value. Transmission power setter 108 performs the setting of transmission power corresponding to the power control information and provides a control to transmit by the set power. That allows improving of a battery saving and moderating of the specification of amplifiers in a transmission/reception apparatus, thereby resulting in decreased interference to signals of other users in the CDMA communication.
