Abstract
The present invention concerns a data communication method for communicating packetized data via an interface between a transmitter and a receiver, wherein communication relies on a layered communication protocol stack comprising at least two protocol layers of different hierarchy level, wherein at least data communication on a lower one of the layers adopts a retransmission scheme for data packets for which an acknowledgment of receipt was not received at the transmitter, the method comprising the steps of initializing the retransmission scheme of the lower one of the layers by setting a condition parameter, wherein fulfilling the condition defined by the condition parameter represents an indication as to how to control the retransmission scheme, wherein initializing comprises setting said condition parameter of the lower one of the layers according to information forwarded from the higher one of said layers to the lower one of said layers, transmitting packet data from the transmitter via the interface to the receiver according to the retransmission scheme of the lower one of the layers, detecting that the condition is fulfilled during transmitting, and controlling said retransmission scheme of the lower one of said layers in response to the detecting.
