A forward power saturation protecting method for CDMA communication system and its power controller are disclosed. Said controller is composed of an emitting power control unit, a transceiver and a TPC instruction counter for base station, or a transceiver, a received signal quality determinator and a TPC instruction generator for mobile station. It can ensure that the limited power is distributed to the user whose communication quality is very poor and the communication channel quality can be quickly compensated.
