The effective capacity of the multi-user OFDMA (Orthogonal Frequency-Division Multiple Access) system for time-varying channel is characterized. Then to maximize the system average effective capacity, through the Tayler approximation, an asymptotical optimal user scheduling is proposed, which selects users based on the relationships among the moving speed, traffic profile and the effective capacity. By means of simulations, it is further shown that the proposed scheme can improve the effective capacity of the mobile hosts.
