Abstract
An automatic and adjustable power control method and apparatus for optimally controlling the output power of a CDMA handset is provided. The method and apparatus utilize a single control signal to automatically control the gain of two frequency diverse variable gain stages of a transmitting portion of the handset by a multi-point hand-off technique. The multi-point hand-off technique partially varies the gain of a first stage to satisfy key system constraints and hands-off control to a second stage. The gain of the second stage is varied to satisfy additional system constraints. A second hand-off is performed so that the gain of the first stage may be varied again to maintain the optimal power control.
