Abstract
A protection method for forward power saturation in a CDMA communication system and its power control apparatus are provided. The power control apparatus includes a base station (BS) transmitting power control unit, a base station (BS) transceiver and a transmitting power control (TPC) instruction counter. The mobile station includes a mobile station (MS) transceiver, a quality detector for a received signal, a TPC instruction generator. Through a saturation decision process and a saturation protection process, a limited power is distributed to a subscriber whose communication quality actually deteriorates and a subscriber whose communication quality deteriorates severely due to deep fading is rapidly compensated. Meanwhile, the protection method and control apparatus are capable of balancing the power and providing average power distribution among subscribers who need power increasing urgently. <IMAGE>
