ABSTRACT:
The present invention relates to a 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 of selecting a set of sub-carriers on which said user data are to be transmitted between said transmitter and said receiver.According to the present invention, the method comprises the steps of:Sending from said transmitter, before transmission of said user data, an indication related to a threshold;Determining at the receiver a quality level for each sub carriers;Selecting at said receiver sub carriers to received said user data as a function of said indication related to a threshold and of said quality levels.
