Abstract :
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 outage probability.
