In this paper; we derive an analytical model for the delay bound of the down link (base station to mobiles); in a single cell Orthogonal Frequency Division Multiple Access (OFDMA) cellular system. The delay bound is exploited in formulating a dynamic subcarrier assignment strategy that equalizes both the queuing; and the channel throughput performances in response to the time-varying nature of frequency selective fading channels. Optimal subcarrier's transmission power allocation is found by solving a constrained optimum rate allocation problem. Results have indicated that the proposed strategies exploit the time varying channel conditions in an efficient way; and have the prospects to improve the queuing delay while maximizing the data transmission rates in real life networks. © Faculty of Engineering Alexandria University;
