Patent ID: 8712464

Claim:
A method of generating transmit power control feedback for a power control channel that lacks both error coded data and known data comprising: setting a target signal quality for power control of the power control channel that corresponds to a target power control command error rate, according to a defined signal-quality-to-command-error-rate mapping function; receiving power control commands over the power control channel; estimating a signal quality for the power control channel based on the received power control commands; and generating transmit power control feedback for the power control channel by comparing the estimated signal quality to the target signal quality; wherein setting the target signal quality comprises determining the target signal quality value by: using the target power control command error rate to access a data lookup table embodying the defined signal-quality-to-command-error-rate mapping function; or using the target power control command error rate as an input value to a polynomial function embodying the defined signal-quality-to-command-error-rate mapping function.
