    摘要: 本篇論文考量在IEEE 802.16m OFDMA Frame架構下,分析框架比例對於LRU Utilization之影響 ,並針對問題提出A Dynamic Downlink/Uplink Resource Adjustment Mechanism (DRAM),藉此尋找出可以並行傳輸的傳輸對組合來改善LRU utilization並且同時考量Femtocells之干擾。首先DRAM利用Advanced Mobile Station(AMS)與Femto Advanced Base Station(ABS) 的位置關係建構出干擾關係圖,根據關係圖依序調整各個Femto ABS的框架比例,藉此改善LRU Utilization。最後在模擬的結果可以明顯看到DRAM之LRU utilization、system throughput以及service ratio這三項數值明顯比其他做法來的好上許多。
    The thesis investigates the impact between the ratio of downlink/uplink subframes and logical resource unit (LRU) utilization in the IEEE 802.16 OFDMA systems. Based on the relationship, the thesis proposes a dynamic downlink/uplink resource adjustment mechanism (DRAM) for LRU utilization improvement by finding the concurrent transmission pairs based on the interference relationships among femtocells. First, DRAM constructs interference relationship graph based on the location information of advanced mobile stations (AMSs) and femto advanced base stations (ABSs) and adjusts the ratio of downlink/uplink subframes for each femtocell. Finally, the simulation results show that the LRU utilization, system throughput and service ratio of DRAM outperforms other related work.
