Abstract
A method of communicating between a transmitter and a receiver based on frames is provided. An error detection code is added to each frame to be transmitted by the transmitter. The frames to be transmitted by the transmitter are transmitted and the transmitted frames are received by the receiver. An error detection code is re-computed based on the received frames by the receiver. At least one frame which has been correctly received based on a comparison of the error detection code of each frame with the re-computed error detection code of each received frame is acknowledged. An error indication frame is sent by the receiver when an error is detected based on the comparison result. If a retransmission condition is detected by the transmitter by receiving an error indication frame from the receiver or if no acknowledgement frame was received by the transmitter from the receiver in a predetermined time interval, the currently transmitted frame is aborted and the transmitter inserts a trailer. As a further possibility instead of inserting a trailer, the start of re-transmission can be indicated by using a retransmission indicator.
