<p>Method for transmitting user data between a transmitter and a receiver in a multi-carrier radio communication system having a plurality of 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, said method further comprising the steps of:
determining at the receiver a quality level for each sub carrier;
sending said quality level from the receiver back to the transmitter;
sending from said transmitter, before transmission of said user data, a threshold which can be the number of sub carrier to select or a quality threshold;
at the receiver deducing which sub-carriers will be used for transmission by selecting the sub-carriers starting with the sub-carrier having the highest quality level and continuing to select the sub-carriers with decreasing quality level until the threshold is reached. The corresponding transmitter is also described.</p> |
