Abstract:
In a multi-tone data transmission system, data are modulated on a set of M tones for being transmitted between a transmitter and a receiver. The data retransmission request device in such system is adapted to request retransmission of a data transmission unit that is hierarchically modulated at a particular hierarchical level and that is modulated on a particular group of N tones, N being a positive integer value greater than one and smaller than or equal to M.
