1. a selection is used to send the method for the automatic repetitive requests method of Frame, and this method comprises:

  • Determine the desired signal to noise ratio of successful decoded frame;

    The initialization frame;

    Reception is corresponding to the channel snr measurement report of the frame of initialization;

    Use measurement report to upgrade the accumulation snr value that receives, wherein this value representation is used for the estimation in the accumulation signal to noise ratio of the reception of the systematic bits of the frame of initialization;

    Determine whether initialization fails;

    Started originally when sending failure, relatively Lei Ji snr value and snr threshold;

    AndBased on the comparison, select automatic repetitive requests method to be used for retransmit frames.
