Abstract
A system and method for proactive repeat transmission of data units sent using an unreliable transmission medium for the delivery of time sensitive data content predicts a future condition of a downlink data distribution channel using current channel estimation information. The predicted channel condition is used to determine which data units in a next data frame are likely to decode incorrectly, and a repeat transmission of those data units is explicitly requested by the receiving equipment, or automatically scheduled by the sending equipment using time domain channel state information provided to the sending equipment by the receiving equipment.
