Orthogonal frequency division multiple access (OFDMA) is considered as the multiple access system for next generation wireless communications and provides multichannel structure. The results of this paper can be divided into two folds. First, the basic equation for multichannel OFDMA slotted ALOHA is devised considering the maximum number of allowed retrials, retransmission probability and the number of users involved in collisions. It is shown that the basic result is independent of retransmission probability as well as the number of users involved in the collision. In the second fold of the paper, we obtained the optimum number of channels with the variation of new packet arrival rate and the maximum allowed number of reattempts, under two conditions. These two conditions are: the system is stable, and provides maximum throughput.
