Estimating the term…
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 according to a defined probability-to-CER mapping function. By way of non-limiting example, these embodiments may be used to provide power control feedback for power control commands transmitted on a Fractional Dedicated Physical Channel in WCDMA systems.
A method of generating transmit power control feedback for a power control channel that lacks both error coded data and known data comprising:
A power control circuit for use in a wireless communication device or system, said power control circuit being operative to generate transmit power control feedback for a power control channel that lacks both error coded data and known data, said power control circuit comprising:
A wireless communication device comprising a power control circuit configured to generate transmit power control feedback for a power control channel received by the wireless communication device, wherein the power control channel lacks both error coded data and known data, and the power control circuit is configured to:
A non-transitory computer readable medium storing a computer program for generating transmit power control feedback for a power control channel that lacks both error coded data and known data, the computer program comprising:
