To allocate a number of data elements which constitute a data symbol to a set of carriers used for transmission in multicarrier applications, a full capacity step and capacity fine tuning step are executed successively. In the full capacity step, the individual capacity or maximum amount of data elements that may be allocated to a carrier is determined for each carrier which forms part of the set of carriers. This maximum amount of data elements is then allocated to each carrier in such a way that a full capacity occupation of the carrier set is obtained. In case of undercapacity, i.e. in case more data elements have to be allocated to the set of carriers, the capacity of the carrier set is enlarged, for example by power boosting, and additional data elements are allocated to the carriers in accordance to a predetermined rule. In case of overcapacity on the other hand, data bits previously allocated to the set of carriers, are removed from some carriers selected in accordance with another predetermined rule. <IMAGE> |
