摘要：

The inter-cell interference in the downlink for IEEE 802.16 wireless metropolitan area network (MAN) mainly depends on the distance between the base station (BS) and the subscriber station (SS). In order to improve the spectrum efficiency and make the frequency reuse factor approach 1.0, the wireless scheduling for supporting the diverse quality of service (QoS) should consider the other-cell interference. In this paper, the wireless packet scheduling algorithms are based on the jointly considering inter-cell interferences, service status, and channel conditions. The advanced scheduling algorithms are proposed for Unsolicited Grant Service (UGS), real time polling service (rtpS), non real time polling service (nrtPS), and best effort (BE) services. Numerical results reveal that the proposed interference coordination based scheduling algorithm improves the overall network throughput, provides an efficient user throughput, and guarantees the diverse QoS requirements.
