Abstract

The present invention is a novel and improved method and apparatus for controlling the transmission power in a closed loop power control system. In the present invention, power control commands are issued in response to the reception of portions of a frame. An adaptive threshold is generated based on the energy of all other portions of the received frame and the energy of the current power control group is compared to this adaptive threshold.
