Patent ID: 8437315

Claim:
A method in a wireless mobile device for fractional dedicated physical channel (F-DPCH) processing in a high-speed data packet access (HSDPA) application, the method comprising: receiving a radio frequency (RF) signal from a serving high speed downlink shared channel (HS-DSCH); producing a baseband signal from the received RF signal; processing the baseband signal to produce a processed baseband signal; when an uplink channel of the wireless mobile device to a serving HS-DSCH cell is a legacy WCDMA dedicated physical channel, providing the processed baseband signal to a WCDMA processing block for apportioning F-DPCH processing to: produce a set of soft symbol outputs from the processed baseband signal; detect, by the wireless mobile device, whether transmit power control (TPC) command bits are present in the set of soft symbol outputs, wherein the TPC command bits are conveyed over non-dedicated pilot bit positions in the processed baseband signal; when the TPC command bits are detected in the processed baseband signal, process the set of soft symbol outputs to produce estimated TPC command bits to be applied to the uplink channel based on the legacy WCDMA dedicated physical channel; generate a TPC quality estimate based on the estimated TPC command bits; and adjust a signal-to-interference ratio (SIR) for the WCDMA dedicated physical channel based upon a comparison of the TPC quality estimate with a TPC quality target to effect F-DPCH power control.
