Frequency band and slot selection scheme for downlink packet transmissions in cellular band division MC-CDMA systems

This paper proposes a downlink frequency band and slot selection scheme for cellular bandwidth division MC-CDMA systems. The proposed scheme selects transmission frequency band and slot according to the signal-to-interference ratio estimated by using the pilot signal at mobile stations. Simulation results show that the proposed scheme improves the downlink throughput but degrades delay performance and it has a trade off between throughput and delay performance. By selecting suitable control parameters, the proposed scheme achieves the throughput improvement without sacrificing the delay performance.
