Method and apparatus for adjusting power control setpoint in a wireless communication system

In a wireless communication system, a method for adjusting a setpoint indicative of a target received signal quality for a transmission, comprising:

• receiving one or more frames from the transmission;
• decoding the one or more received frames in accordance with a particular decoding scheme to provide one or more decoded frames;
• determining status of each decoded frame;
• determining a power surplus or deficit indicative of the received signal quality for the transmission being respectively greater than or less than the setpoint;
• and
• adjusting the setpoint based at least in part on the determined status and power surplus or deficit.

A power control unit for use in a wireless communication system, comprising:

• a decoder configured to decode received frames in accordance with a particular decoding scheme to provide decoded frames;
• a checker configured to receive and check the decoded frames to provide status for the decoded frames;
• a metric calculation unit configured to provide one or more metrics indicative of confidence in decoded results for the received frames;
• and
• a power control processor configured to receive the status and one or more metrics for the decoded frames and to adjust a setpoint for a power control loop based at least in part on the received status and one or more metrics, wherein the setpoint is indicative of a target received signal quality for the received frames.
