Abstract:
1. A method of scaling soft symbols of an uplink Enhanced Dedicated transport Channel (E-DCH) received from a user in a network for processing in a base station receiver in the network employing a log-MAP turbo decoding algorithm to process the E-DCH, the E-DCH having an Enhanced Dedicated Physical Data Channel (E-DPDCH) from which the soft symbols are generated at the base station receiver, and an Enhanced Dedicated Physical Control Channel (E-DPCCH) used to transmit control information associated with the E-DPDCH, which along with configuration information from a radio network controller (RNC) enables the base station receiver to determine a reference amplitude ratio linked to the actual power offset of the E-DPDCH from a legacy DPCCH, the method comprising: determining an estimated E-DPDCH to DPCCH amplitude ratio that represents a scaling factor for the soft symbols, and scaling the soft symbols by the scaling factor to enable the soft symbols to be processed by the log-MAP turbo decoding algorithm in the base station receiver.
