摘要(中)

為了滿足現今的網路需求的快速成長以及資料傳輸嚴格的時間延遲要求。這篇論文的目標希望降低大小基地台間的干擾並藉由波束賦形來提升波束的利用率來有效的提升系統效能以及降低最佳化的計算時間。在LTE中，增強型蜂巢式區域間干擾消除技術利用統一的ABS配置也就是所有大小基地台都使用相同的ABS配置來降低基地台間的干擾，並利用基地台範圍擴展技術來達到負載平衡。然而採用統一的ABS配置會因為無法有效的利用每個基地台的波束而造成系統資源的浪費。為了解決這個資源浪費的問題，我們提出一個在雙連線環境下使用非統一的ABS配置結合基地台範圍擴展技術可以使得每個基地台的波束都有自己最佳的ABS比例來提升波束的利用率。在這篇論文中，當小基地的波束上具有小基地台邊緣使用者時，讓小基地台邊緣使用者在ABS訊框接收下行資料且讓小基地台中心使用者在非ABS訊框接收下行資料。當小基地台的波束上不存在小基地台邊緣使用者時，讓小基地台的中心使用者可以在ABS以及非ABS訊框接收資料。最後我們使用Gurobi這個最佳化計算工具來評估演算法的效能及執行時間。

摘要(英)

In order to satisfy increasing traffic demands, 5G network supported beamforming to improve the system throughput. This paper aims to reduce the interference between macro cell and small cell and increase the system beam utilization by beamforming to efficiently improve the system throughput and decrease the execution time of optimal ABS allocation computation. In LTE, traditional enhanced Inter-Cell Interference Coordination reduces the interference between cells by Uniform ABS allocation and achieves load balancing by Cell Range Expansion. However, adopting Uniform ABS allocation will waste the system resources because it can′t fully utilize the beam of each cell. In order to address the waste of resources problem, we proposed a beam-based Non-uniform ABS allocation with CRE in Dual Connectivity algorithm that made each beam of cells use its own optimal ABS ratio to increase the beam utilization and each small cell have its own optimal CRE bias. Other than this, in this paper, if there are small cell edge users located at the beam of small cell, we will allocate the ABS subframes for small cell edge users and Non-ABS subframes for small cell center users. If there are no small cell edge users located at the beam of small cell, we will allocate the ABS subframes and Non-ABS subframes for small cell center users to receive downlink data. Final, we used Gurobi which is a commercial optimization solver to evaluate our performance and execution time.
