a new cross-layer resource allocation scheme based on OFDMA systems was proposed to maximize overall data throughput on the premise of achieving diverse QoS, simultaneously, to ensure fairness between users as much as possible. The scheme takes full account of the QoS requirements at MAC layer and large-scale fading characteristics of wireless channels, and makes a joint design of packet scheduling at the MAC layer and resource allocation at the physical layer. Packets are scheduled at the MAC Layer according to each user's timevarying channel bandwidth which reversly was assigned in physical layer based on user's queue state information at the MAC layer. Simulation results show that this solution can meet users' QoS requirements, increase the downlink total throughput of the system and improve the fairness between users with different path loss.
