And transmission method for efficient packet data transfer in a transmission protocol with repeat requests.

Method for transmitting data packets (D n) from a transmitter (TR) to a receiver (RE), wherein identifications of transmitted data packets are stored, the defective data packets (D n) are detected by the receiver (RE), status messages (S11, S12) applying defective data packets for retransmission are sent from the receiver (RE) to the transmitter (TR) and retransmissions of requested data packets according are made with status messages (S 11, S 12), wherein the transmitter (TR) evaluates a first status message (S 11) with an identification of at least one first requested data packet and retransmits the first data packet, and transmitter evaluates a further status message (S12) and detects at least one further data packet that is requested for a retransmission, wherein the transmitter (TR) initializes a timing unit according to the retransmission of the first paqu ete data where the timing unit or a threshold for the timing unit is attributable to the identification of the first data packet, if the identification of further data packet corresponds to the identification of the first data packet, the transmitter ( TR) selects the further data packet if the timing unit has reached the threshold, and the selected data packet is retransmitted.
