CDMA transmission power control in variable control cycle

In a CDMA transmission power control system for controlling reverse transmission power of reverse transmission power for a mobile station, a Doppler frequency detector (50) detects a maximum Doppler frequency using a pilot symbol extracted from a desired transmission data signal per transmission power control period. When the maximum Doppler frequency is smaller than a Doppler frequency threshold, the system performs a closed loop control in a cycle of the transmission power control period. On the other hand, when the maximum Doppler frequency is larger than the Doppler frequency threshold, the system performs the closed loop control in a cycle of N times the transmission power control period in appearance.
