Abstract

The present invention relates to a transmitting apparatus, a receiving apparatus, a system and a method of re-transmitting data, wherein a signal, which has been transmitted on a first set of original subcarriers, is re-transmitted on a second set of re- transmission subcarriers. A transmission quality information of the original subcarriers and the re-transmission subcarriers is compared and the second set of re-transmission subcarriers is obtained by assigning a re-transmission subcarrier with the highest transmission quality not yet assigned among the second set to an original subcarrier with the lowest transmission quality among the first set.
