Abstract:	在現今無線通訊網路系統，有許多針對頻寬資源分配的研究與討論，由於近年來無線網路系統的快速發展，對於無線資源的需求也隨之與日俱增，但由於現今對於無線頻寬資源的缺乏，LTE-Advanced系統下的載波聚合技術用以解決4G 系統提供大帶寬、更高峰值速率的需求。本篇論文提出在LTE-Advanced 系統架構下使用載波聚合技術的資源分配演算法，針對CA 技術環境下會衍生的問題，提出在保障使用者基本需求為基礎，針對不同訊務類型的使用者，在滿足其服務品質(Quality of Services, QoS)的前提，追求系統的更大效能為目標的排程法則。並透過模擬的結果，來驗證並分析演算法的效能與公平性等評估指標。 With respect to current wireless communication systems, there are many researches involving the discussion of radio resource allocation. As the wireless network grows rapidly, there is also a large increase in wireless requirement. Because of the lake of the radio resource, LTE-Advanced proposed carrier aggregation Technology to support widely band and high peak data rate. To achieve high system throughput and still satisfying the basic requirements for users’ Quality of Service (Qos) datarate, the dissertation proposed a QoS-based Resource Scheduling for LTE-Advanced System with Carrier Aggregation. The simulation result used to prove the improving of the system.
