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...
A cell planning and resource allocation scheme for improving channel capacity and for maintaining QoS (quality of service) over a downlink OFDMA (Orthogonal Frequency Division Multiple Access) system is proposed. The frequency overlay is applied to improve link capacity and the sectorization is reduce the influence of carrier collision. This consideration enhances link capacity of system with a proper...
