1. Method for transmitting user data between a transmitter and a receiver in a multi-carrier radio communication system having a plurality of orthogonal frequency sub-carriers, said method comprising the steps ofat the receiver, determining quality levels for said sub-carriers;

  • sending said quality levels from said receiver to said transmitter;

    selecting, based on said quality levels, a set of sub-carriers on which said user data is to be transmitted between said transmitter and said receiver,from said transmitter, before transmission of said user data, sending an indication related to a threshold, said indication and said quality levels enabling said receiver to deduce said set of sub-carriers on which said user data is to be transmitted; and

    at said receiver, selecting said set of sub-carriers on which said user data is to be transmitted as a function of said indication and of said quality levels.
