Abstract: The iterative decoding of blocks may be continued or terminated based on CRC checks. In an example embodiment, one iteration of an iterative decoding process is performed on a block whose information bits are covered by a CRC. The iterative decoding process is stopped if the CRC checks for a predetermined number of consecutive iterations. In another example embodiment, a decoding iteration is performed on a particular sub-block of multiple sub-blocks of a transport block, which includes a single CRC over an entirety of the transport block. The CRC is checked using decoded bits obtained from the decoding iteration on the particular sub-block and decoded bits obtained from previous decoding iterations on other sub-blocks of the multiple sub-blocks. The decoding iteration is then performed on a different sub-block if the CRC does not check. Also, the decoding iterations for the sub-blocks may be terminated if the CRC checks.

Abstract translation: 可以基于CRC校验继续或终止块的迭代解码。 在示例实施例中，对其信息比特被CRC覆盖的块执行迭代解码处理的一次迭代。 如果CRC检查预定数量的连续迭代，则停止迭代解码过程。 在另一个示例实施例中，对传输块的多个子块的特定子块执行解码迭代，其在整个传输块上包括单个CRC。 使用从特定子块上的解码迭代获得的解码比特和在多个子块的其他子块上从先前的解码迭代获得的解码比特来校验CRC。 如果CRC不检查，则在不同的子块上执行解码迭代。 此外，如果CRC校验，则可以终止子块的解码迭代。

Abstract: Systems and methods for computing and/or utilizing mutual information based link metrics for a link in a wireless mesh network are disclosed. In one embodiment, one or more mutual information values are computed for a link between a transmitter of a first network node and a receiver of a second network node in a wireless mesh network. Each of the one or more mutual information values is computed for a different hypothesized transmission mode for the link. One or more link metrics for the link are computed as a function of the mutual information values, where each link metric is computed based on a different one of the one or more mutual information values. In this manner, a link metric is computed for each of the one or more hypothesized transmission modes for the link. At least one of the link metrics are then provided to a routing update module.
