Radio resource allocation and packet scheduling schemes are expected to play a key role in the overall performance of OFDMA-based wireless networks. Inevitably, efficient resource allocation strategies have to exploit information laying in different OSI layers, allowing for a cross-layer design. In this work we evaluate current static resource allocation schemes (PHY layer) and extend them to incorporate MAC layer information. Furthermore, we enhance current schemes with SNR scheduling in time-domain, achieving near optimum system performance. The evaluation is based on our joint MAC-PHY layer system model. Scheme's performance is evaluated in terms of average throughput-delay through simulations.
