Abstract
設備與設備(Device-to-Device, D2D)之通訊將是長期演進技術(Long Term Evolution, LTE)網路中的重要通訊之一,D2D通訊可應用於蜂巢式網路並且重複使用基地台的資源可提高整體系統容量以及資源利用率(Resource Utilization),其中D2D用戶允入數量以及資源分配機制是重要的關鍵因素。本研究首先根據D2D用戶允入數量以及資源分配機制之條件下尋找出系統容量的最佳值,並且提出D2D位置推薦演算法(Location Recommendation, LR)來改善系統容量。根據結果顯示,D2D用戶透過演算法的移動後可有效地提升整體系統容量以及資源利用提升率。
Device-to-Device (D2D) communication becomes one of the important technologies in long-tern evolution (LTE) networks. D2D communication underlying cellular networks can increase capacity and resource utilization. User admissions and resource allocation (RA) are the key to D2D communication. First, in the conditions of this study D2D user admission and RA looked for the best value system capacity, and proposed recommended location for D2D users to enhance system capacity. The simulated results show that D2D users can effectively enhance the overall system capacity and utilization after the possible moves of algorithm.
