Open the CIPO recordAbstract From the Canadian patent
A wireless communication device or system generates transmit power control feedback for a received power control channel by determining a command error rate (CER) or by identifying a target signal quality for the power control channel according to a defined signal-quality-to-CER mapping function. Generally the power control channel does not include error- coded data to use for CER estimation. However in one embodiment, the channel does include known reference bits that are evaluated for CER estimation with the estimated CER used to set the signal quality target for inner loop power control. In other embodiments a computed reception error probability is used to identify a CER estimate …
