Abstract
Provides apparatus, systems and methods for adapting a first and second transmission parameter R, P in a transmitting node of a data communication system to the current link quality of a data communication channel. A method comprises in the transmitting node counting the number of successful transmissions s, each successful transmission bases on a receipt of an acknowledgment “ACK”, and comparing the number of successful transmissions s against a threshold value Smax. In the event of reaching the threshold value Smax and operating with the first and second transmission parameter R, P in a predetermined parameter space, the method further comprises adapting at least one of the first and second transmission parameters R, P in dependence on a critical value that due to the current link quality corresponds to a temporarily unsupported value of one of the first and second transmission parameters R, P.
