Abstract
A method for transmitting a payload encapsulated in a packet from a transmitter to a receiver by using an Automatic Request process, in which: the receiver checks each packet received from the transmitter to detect some potential corrupted received packets the receiver acknowledges the correct or the corrupted reception of each received packet by emitting one or many acknowledgment messages to the transmitter; the transmitter resends the packets that were indicated as corrupted in the received acknowledgment messages. For at least some packets, the transmitter implements an EC-PartARQ error control mechanism including the steps of: defining a sensitive part and a non-sensitive part in the transmitted packet; checking only the sensitive parts in the packets to detect any potential corrupted received packet, a packet being considered as corrupted if the sensitive part has not been correctly received.
