Abstract

In this paper, we address the problem of adaptive radio resource allocation and QoS provisioning for real-time (RT) and non-real-time (NRT) services in OFDMA systems. The proposed algorithm tightly couples the subchannel allocation and packet scheduling together through an integrated cross-layer approach in which each packet is assigned a priority value by taking both the instantaneous channel condition and the QoS requirements into account. An efficient suboptimal algorithm with low computational complexity is proposed to solve the linear optimization problem. Simulation results show that the proposed algorithm can greatly improve the system performance in terms of high spectral efficiency and low outage probability compared to the traditional TDMA algorithm, thus is very suitable for the downlink of current OFDMA systems.
