Abstract
A physical layer retransmission control method is used for retransmission control of a transmission system. The transmission system includes a first transmission terminal, a second transmission terminal and a transmission channel. The first transmission terminal sends downlink data packets to the second transmission terminal through the transmission channel. The second transmission terminal sends retransmission control information to the first transmission terminal through the transmission channel. Each downlink data packet includes a sequence number and an abnormal state field. The sequence numbers in the consecutive downlink data packets are arranged in the order of transmission. The abnormal state field indicates the abnormal state of the data of the first transmission terminal. If the second transmission terminal judges an error in the downlink data packet, it sends retransmission control information to the first transmission terminal, and the first transmission terminal retransmits the downlink data packet to the second transmission terminal accordingly.
