A mathematical model of the distribution of frequency resource balancing problem as the number of subchannels downlink between the subscriber stations network WiMAX. Comparative analysis showed that the best performance on the downlink performance provides a method of Max C/I Ratio, as well as the proposed model. From the perspective of a balanced distribution of bandwidth downlink best results were in methods Round Robin and Proportional Fair, provided the requirements for low transmission rate of subscriber stations. Given the high rate requirements the most balanced distribution of bandwidth downlink provides a model proposed in the article. Given the high rate requirements of subscriber stations proved effective the proposed model, providing each subscriber station transmission rate guaranteed with access to additional (non-guaranteed) bandwidth.
