The Worldwide Interoperability for Microwave Access (WiMAX) is one of the most possible candidates for next generation wireless network technology, and is promoted by WiMAX Forum as a leading technology for wireless broadband service. Currently, the packet scheduling is not specified in the IEEE 802.16 standard, and is open to vendor implementation. In this thesis, we study downlink scheduling algorithm which is implemented in the Gemtek Pico Base Station (BS). In addition, we designed, modified and implemented several representative downlink scheduling algorithms into the Gemtek Pico BS. The algorithms are studied under several users with different channel condition, in order to test the system throughput, fairness, and frame utilization. From our experiment result, those implemented scheduling algorithms largely improves system average throughput due to channel-aware scheduling policies, and the efficiency of resource utilization is also improved.1341685 bytesapplication/pdfen-US全球互通微波存IEEE 802.16下行排程演算法演算法實作測試平台WiMAXIEEE 802.16eDownlink SchedulingImplementationTestbedthesishttp://ntur.lib.ntu.edu.tw/bitstream/246246/253891/1/ntu-101-R99921029-1.pdf
