<p>Aspects of a method and system for adaptive quantization steps for HS-SCCH decoding using average CQI are provided. A HS-SCCH in a received HSDPA signal may be adaptively quantized before HS-SCCH decoding occurs. Quantization information may be determined based on a CQI value associated with the HS-PDSCH. A preferred soft bit precision and quantization geometry, which associated with the quantization information, for the given soft bit precision may be determined based on the CQI value. The received HS-SCCH data may be truncated with the determined soft bit precision in the determined quantization geometry, accordingly. A look-up table, which may comprise the mappings between CQI and quantization step information, may be used for selecting quantization step sizes in HS-SCCH quantizing in order to, for example, lower the complexity in HS-SCCH quantizing.
