In this paper, we research the wireless resource allocation problem with packet scheduling in both MAC layer and physical layer in multi-user orthogonal frequency division multiplexing (OFDM) systems. Under the practical environment where mobile users receiving signal with different SNR levels in a cell or around a Wi-Fi hot spot, our designed algorithm can execute relatively fair packet scheduling from MAC layer consideration and make efficient use of wireless resources at physical layer. simulation results show that our proposed scheme satisfy most users in various SNR and have better average performance in packet drop rate, packet delay and total throughput.
