Abstract: New generations of cellular networks are expected to meet the exponential evolution of the requirements of the wireless network services. Thus, standards like 3GPP LTE-Advanced and IEEE 802.16m have been developed in different releases in order to fulfil the rather challenging goals. New paradigms such as cooperative relaying, OFDMA access technique and the cross-layer approach have great application potential contributing to this development process. Particularly, these mechanisms are important in macro cell downlink scheduling. Within this paper, two novel algorithms of radio resource management (RRM) denoted Max-of-Max and Max-deviation are proposed. They are standard-compliant cross-layer mechanism in downlink OFDMA networks. If the reduction of the schemes complexity is a main key of this study, the high ubiquitous cell throughput aware fairness among users remains a fundamental purpose. With the aim to investigate the proposed algorithms performance, a selection of numerical results is outlined.
