    • The present invention relates to the fields of adaptive multi-carrier data transmission schemes. The present invention especially relates to a method of adapting transmission parameters of a group of subcarriers, a software program product and a communication device. The method of adapting transmission parameters of a group of subcarriers comprises steps of: determining a channel quality value for each subcarrier; establishing an order of assignment groups, each assignment group comprising one or more subcarriers, based on the channel quality values; assigning, in the order of the assignment groups, a transmission parameter to every assignment group, whereby assigning a transmission parameter to an assignment group comprises assigning the transmission parameter to all subcarriers of the assignment group; and calculating a link performance value based on previously assigned one or more transmission parameters; whereby the step of assigning a transmission parameter to every assignment group is based on the calculated link performance value.
