We propose a QoS-driven resource allocation algorithm in the downlink orthogonal frequency division multiple access (OFDMA) network by integrating information theory with the concept of effective capacity (EC). By exploring the decoupling property of real-time session,we maximizes the network EC by increasing the EC of file transfer users gradually until the system power reaches the threshold while keeping the EC of real-time session users unchanged. Simulation shows that the proposed algorithm significantly improves the overall EC under the delay constraint.
