In this paper, the authors present radio resource allocation scheme to maximize Ergodic rates for OFDMA cellular network. Purpose behind this is to improve multiuser diversity. This paper is to improve multiuser diversity along with maximum Ergodic rates. SNR is considered to maximize erotic rates, along with that packet size is also considered. In this paper, an algorithm is proposed in which criteria for allocating a resource is based on prioritization. Prioritization is based on different parameters such as SNR, maximum power, maximum distance of user from base station, maximum frequency available within a band etc. Simulation results show excellent performance.
