長期演進技術系統下針對聯播傳輸之裝置對裝置叢集生成策略

Abstract

在本篇論文中，我們提出了一個長期演進技術系統下針對聯播傳輸之裝置對裝置叢集生成策略，藉由此策略，我們可以適當地分配使用者裝置(UE)的傳輸模式，由基地台接收資料或藉由裝置對裝置(D2D)傳輸方式接收資料，以此達到本篇論文的目標，降低此系統中最大傳輸時間。經由模擬結果可以知道我們提出的叢集生成策略如預期地降低了最大傳輸時間，同時也降低了平均傳輸時間，且上述兩者與傳統的聯播方式相比皆有顯著的改善。

In this thesis, a clustering strategy for multicast transmission in Device-to-Device (D2D) communication integrated into LTE networks is proposed to decrease maximum transmission time. Through mathematical analysis, we can select some user equipment (UE) as cluster head (CH) who is capable of distributing data to its members by multicast transmission, and arrange their members appropriately to decrease maximum transmission time. The simulation result shows that the clustering strategy decrease maximum transmission time, as well as average transmission time significantly.
