Abstract :
In this paper for the IEEE 802.16 OFDMA system we propose the fast algorithm to find the optimal average number of data block transmissions that minimizes the total downlink and uplink transmission power subject to satisfying QoS requirements. We show that the optimal average number of data block transmissions in the IEEE 802.16 OFDMA system is almost independent of the coding and modulation scheme used, propagation channel model, and data block size. In the IEEE 802.16 OFDMA system the optimal average number of data block transmissions is very close to 1.18
