設計於LTE網路下Multi-RAT資料流量之資源分配機制設計

背景與目的：球類運動經常需要追蹤動態的物體，其中棒球及壘球選手需要在比賽中追蹤移動中的球、看著跑步中的隊友及對手以執行最佳的防守，桌球選手在動態視覺與反應需要有較家的能力；因此特別傑出的棒壘球及桌球選手在多物體追蹤能力應較非運動員有如此更佳的能力。本篇研究目的在於分析此假設並且探討在不同運動時期的棒壘球選手其多物體追蹤能力是否有所差異。方法：49名男性棒球選手、25名女性壘球選手、7位男性桌球選手、39名非運動員（20名女性及19名男性）參與本研究，所有參與者接受典型多物體追蹤測驗(Pylyshyn & Storm, 1988)。在此測驗中參與者被要求專注追蹤特定目標，並有數顆使其分心的移動球體移動數秒，之後參與者選擇出需要追蹤的球體。其中實驗一強調在物體移動速度的追蹤，實驗二強調在追蹤球體的數目以此了解參與者的追蹤及注意力限制能力。其中棒球及壘球選手並在訓練期與比賽期各被測驗一次。結果：無論實驗一或實驗二，棒球選手皆顯著優於一般非運動員，壘球選手非顯著的較棒球選手差但優於一般非運動員，桌球選手在追蹤球體速度上也顯著優於一般非運動員。在專注追蹤的限制能力分析上，棒球選手無論在追蹤球體速度或是球體數目上皆顯著優於非運動員。至於在不同運動時期之多物體追蹤能力上，則發現棒壘球運動員在比賽期及訓練期皆無顯著差異。結論：本研究發現棒球選手確實在多物體追蹤能力優於一般非運動員，但棒壘球運動員在不同運動時期此能力並無明顯的差異。

LTE is one of 3GPP standards developed by 3GPP organization which is organized by telecommunication manufacturers and operators. It is backward compatible with 3G/UMTS cellular systems and competing access network technologies in 4G wireless networks with WiMAX. Multiple radio access technologies (Multi-RAT) means that a base station as eNB/DeNB is composed of more than one radio access technology. Our previous project had proposed a basic Multi-RAT Virtualization structure in DeNB. To design an appropriate scheme of resource allocation for Multi-RAT traffic flow with QoS requirement is necessary because eNB/DeNB should handle and identify many multiplexing backhaul QoS traffic flows simultaneously. To support heterogeneous traffic QoS requirement, the cross-layer Tagging scheme should be adopted. From MAC layer to PHY layer in eNB/DeNB, the physical capacity of radio resources are variant due to different CQI states in each RB. How to arrange different upper layer traffic flow requirements to varied RBs is an important issue. Therefore the cross-layer LTE resource allocation scheme and scheduling policy are proposed in this project. This project focuses on multiplexing traffic Tagging and MAC and PHY layers resource allocation and scheduling schemes. Our proposed schemes might improve the system usage and total radio resource utilization in LTE E-UTRAN environment. Moreover, these resource allocation schemes can not only support our previous Multi-RAT Virtualization structure, but also the regular LTE structure in LTE network.
