The goals of this chapter are for the reader to have a basic understanding of resource allocation problem in OFDMA-based systems and, to have an in-depth insight of the state-of-the-art research on that  ...  Emerging broadband wireless systems such as WiMAX and 3GPP/LTE employ Orthogonal Frequency Division Multiple Access (OFDMA) as the basic multiple access scheme.  ...  Further work will focus on the combination of our proposals with CQI feedback schemes in order to assess the robustness of our proposals with respect to partial and inaccurate CQI reporting schemes.  ...
