  • METHOD AND SYSTEM FOR DATA TRANSMISSION UNIT RETRANSMISSION, DATA RECEIVER AND DATA TRANSMITTER
    Publication number: 20080175186
    Abstract: A method and system for data transmission unit retransmission between a data receiver and a data transmitter. A data receiver determines that there is a missing data transmission unit based on a non-acknowledgement mechanism. The data receiver transmits identification information of correctly received data transmission units which are in the same link as the missing data transmission unit to a data transmitter. The data transmitter determines a data transmission unit which needs data retransmission according to the identification information it has received, and retransmits the data transmission unit.
