摘要
A base station of the cellular telephone forward link power control system transmits frames initially at a high default transmit power level, then decreases the power level incrementally until either a frame erasure is detected, triggering an immediate sharp increase in transmission power, or until a predetermined period of time has elapsed, after which the base station performs a fast downward move in the transmit power level. The fast downward move constitutes a sharp reduction in the transmit power level. In one example, the fast downward move is performed if one hundred consecutive frames are successfully transmitted without a frame erasure. By providing the fast downward move in transmit power, the power transmitted is decreased on the average. In particular, the fast downward move allows the amount of transmit power to be reduced significantly in circumstances where slow incremental decreases in power would result in excess power being employed. Method and apparatus embodiments are disclosed.
