It has been proven that the IEEE 802.16 broadband wireless access (BWA) network is the most preferable next-generation network with the well defined quality of service (QoS) framework. Due to lack of the scheduling algorithm for the guaranteed QoS in the IEEE 802.16 standard, many results for the scheduler of the IEEE 802.16 BWA network have been proposed. However, for the downlink transmission with the aggregate flow sharing the class queue, it is hard to guarantee the QoS requirements in the location-dependent wireless channel errors. In this paper, we propose a class-based downlink scheduling algorithm to compensate the wireless channel errors and to guarantee the QoS requirements.
