Abstract
A method for quantizing decision metrics (e.g., log likelihood ratios (LLRs)) for reduction of memory requirements in wireless communication is described. The method includes selecting a quantization algorithm. The quantization algorithm may be selected as a function of a characteristic of a decision metric representative of a transport block received over a communication channel, a characteristic of the transport block, or a condition of the communication channel. The method further includes quantizing the decision metric using the selected quantization algorithm to generate at least one quantized decision metric representative of the transport block. The method further includes storing the quantized decision metric and an indicia of the selected quantization algorithm to enable recovery of the decision metric representative of the transport block prior to decoding.
