In this paper we theoretically perform joint fragment size and transmission rate optimization for request-tosend/clear-to-send mechanism of IEEE 802.1lb distributed coordination function considering both collisions due to system load and frame errors due to non-ideal channel conditions. We have chosen system throughput maximization as the optimization(More)
In this letter we introduce our system load model for the orthogonal frequency division multiple access (OFDMA) network. We formulate the requirements to the system load model and present its definition. The system load model comprises the uplink load, the downlink load, the sector load, and the network load. We describe our approach to combine the(More)
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(More)
