摘要： A method and system for providing efficient transmission power control commands to a base station. In a third generation IS-95 CDMA network, for example, cdma2000, the forward pilot channel is used to estimate the received signal power level. In the presently preferred embodiment, a mobile station measures the received pilot channel power, on a forward link pilot channel. The loss experienced on the pilot channel is estimated as the difference between the pilot channel power transmitted at the base station and the pilot channel power received at the mobile station. The pilot power transmission power is typically fixed based upon the operating environment of the base station. The fixed pilot channel transmission power can be transmitted via a message from the base station. Based on the estimated channel loss, the received traffic power is calculated as the difference between the initial traffic channel transmission power, that is, the power when the mobile station is assigned a traffic channel, and the estimated loss added to any power control gain corrections that have occurred. The initial traffic channel transmission power can be a default value or can be assigned by the base station using signaling messages, e.g., a forward common control channel (or F-CCCH) message. Power control decisions are made based on the ratio of received traffic channel energy with an estimate of interference and noise on the channel. A “power control decision” is made by comparing the ratio with a predetermined threshold to determine if the power level should be raised or lowered.
