LTE-A(Long Term Evolution-Advanced)是現在無線通訊發展的重要方向,大幅的提升了下行的傳送能力,多媒體服務更是日益漸增,如何將有限的資源提供給使用者並保障其服務的QoS便是一個重要的議題。隨著小型基地台的出現,雙重鏈結也被廣泛的研究,我們使用雙重鏈結技術將資料分流給小型基地台代為傳送,大大的提升了系統的吞吐量和保障服務的QoS。此外我們提出了一個三階段的下行排程方法,首先是資料分流的階段,我們使用線性規劃的方法計算出各個服務的分流量,在封包真正進行分流之前進行檢查,以確保交由SeNB傳送的封包可以在SeNB傳送成功。接下來是QoS排程方法,我們透過整體規劃的方式動態的將預期將要掉落的封包加入QoS Group中,使之可以提早拿到足夠的資源並且傳輸成功。最後是資源分配的階段,我們將使用提出的Prioritized C/I scheduling方法去分配在QoS Group中的服務,並且將剩餘的資源以PF(Proportional Fair)的方法將資源分配給Non-QoS Group的服務中,在使GBR(Guaranteed Bit Rate)類型的封包不掉落的前提之下,盡量的提升網路的效率。 Nowadays, multimedia application services are become more and more popular. And come along with the traffic demand increasing. For the above reasons, not only the bandwidth but the quality of services are need to be improved. As the appearance of small cell, user could connect the macro cell and small cell simultaneously. This mechanism leverage the loading of marco cell. In this paper, we design an algorithm for Qos-Aware Scheduling for LTE-A Small Cell Network with Dual Connectivity. Our algorithm guarantee the Qos of GBR flows and also improve the efficiency of entire network.
