Forward error correction scheduling for the improvement of the radio link protocol

摘要

Forward error correction scheduling technique to improve the radio link protocol used, such as EV-DO, in a wireless communication system. In one embodiment, I will describe the generation of scheduling repair the encoded symbols to be transmitted with the source data. In another embodiment, in order to control the falling edges of the protective window that is provided by the repair symbols, the acknowledgment message from the receiver is used. In another embodiment, in order to control the generation of extra repair symbols, a negative acknowledgment message from the receiver is used. In another embodiment, in order to avoid transmission of padding bytes in the over-the-air, the length field is used. In another embodiment, to indicate the padding bytes required for the symbol matching the symbol supplemental field is added to the source symbols, the transmission of padding bytes in the over-the-air thereby avoiding further.
