Claim Text:
1. A method at a mobile device, the method comprising: de-spreading one or more data symbols to produce de-spread data symbols, each data symbol representing respective data encoded as a respective quadrature amplitude modulated ‘QAM’ symbol; determining reduced symbols based on the de-spread data symbols, each reduced symbol comprising: storing, prior to modulation demapping to determine soft decisions from the reduced symbols, the reduced symbols in a symbol buffer; while storing the reduced symbols in the symbol buffer and prior to performing the modulation demapping, estimating QAM amplitudes of the de-spread data symbols; after the storing, de-interleaving the reduced symbols to produce de-interleaved reduced symbols; performing, based on the estimating QAM amplitudes, the modulation demapping on the de-interleaved reduced symbols to produce soft decisions; performing constellation de-arrangement of the soft decisions; and based on performing the constellation de-arrangement, performing rate de-matching and HARQ combining of the soft decisions.
