    摘要： Techniques for performing a frequency scan to detect wireless systems operating on frequency channels with variable bandwidths are disclosed. In one aspect, a user equipment (UE) performs a frequency scan for a plurality of frequency channels and measures the received power of each frequency channel based on a center frequency and a bandwidth of the frequency channel. The UE identifies candidate frequency channels for acquisition based on the results of the frequency scan. In another aspect, a frequency scan of a band is performed by partitioning the band into multiple segments, measuring received powers of subcarriers or raster frequencies within each segment, and concatenating received powers of subcarriers or raster frequencies for all segments. A frequency scan is then performed based on the concatenated results for the multiple segments.

    摘要： 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.
