  • Publication number: 20130017828
    Abstract: Aspects of the present application include using adaptive measurement intervals to improve RSSI scan accuracy. A method may involve determining a first power value in respect of a first measurement time interval, determining whether or not the first power value meets at least one criterion, when the first power value does not meet the at least one criterion, determining at least one additional power value, selecting at least one power value from a set of power values that have been determined, the set including the first power value and the at least one additional power value, and determining the power value for use in cell selection or cell re-selection based on the selected at least one power value. The methods may be applied to any cell selection or re-selection scheme for which an adaptive measurement interval may be beneficial.

  • Publication number: 20130013976
    Abstract: Method and a receiver in a communication system for receiving a transport block. The transport block comprises code blocks, each of the code blocks includes an error detection code and an error correction code. Reliability metrics are determined using an input generated during processing of the code blocks after the transport block is received. Each of the reliability metrics corresponds to each of the code blocks. A code block reorderer reorders the code blocks in an order based on the reliability metrics and a selection criterion. A decoder decodes each of the code blocks using the error correction code in the order. A verifier verifies each of the decoded code blocks using the error detection code.

  • Publication number: 20120270537
    Abstract: Described herein are methods and devices for use in telecommunication cell selection and re-selection for which there may be multiple different sizes of transmission bandwidth configurations in a telecommunications operating band. For each of a plurality of channel hypotheses, in which each channel hypothesis has a hypothetical occupied portion and a hypothetical guard band portion, a respective metric is calculated based on a power value for the hypothetical occupied portion and a power value for the hypothetical guard band portion. Based on the metrics determined for the plurality of channel hypotheses, at least one channel hypothesis is selected for further processing for cell selection or re-selection. The metric is calculated by determining a difference between the power value for the hypothetical occupied portion and the power value for the hypothetical guard band portion.

  • Publication number: 20100223524
    Abstract: A method and device for performing forward error (FEC) correction avoidance based upon predicted block code reliability in a communications device is provided. An avoidance unit comprising a metric computation unit and a decision unit generates a reliability metric based upon a received code block. The reliability metric is compared to a reliability threshold, and the forward error correction decoder in the communications device is disabled if the metric is below or equal to the threshold.
