The invention concerns a method of re-sending incorrectly transmitted data (ARQ). To effect transmission between subscriber entities (T1, T2) each of which has at least one transmitting part (1, 10) and at least one receiving part (2, 20), a data stream is divided at the transmitting subscriber's end into data words of predetermined length which are combined to form other data words, the individual data words being temporarily stored in a transmission buffer store (6, 60), optionally transmitted via a transmitter unit (7) and, at the receiving subscriber's end, optionally received in a receiver unit (9, 8) and forwarded after temporary storage in a receiving buffer store (240, 24). An error occurring during transmission is detected and a command issued to the transmitting part (1, 10) of the transmitting subscriber entity, via the transmitter part (10, 1) of the receiving subscriber entity and the receiving part (2, 20) of the transmitting subscriber entity, to re-send the incorrectly transmitted data word. The ARQ re-transmissions of the incorrectly transmitted data are carried out using a predeterminable and invariable proportion of the data words transmitted in an average period.
