於多基地台環境下考量干擾之無線網路資源分配研究

Abstract

在第四代行動通訊的蜂巢式系統中，協調式多點傳輸可以被用來有效減緩干擾。而無線電資源分配是協調式多點傳輸技術中的一個重要的方向，在本篇論文中主要針對了現有的無線電資源分配方法進行改良。我們針對一篇有關無線電資源分配的研討會期刊去做比較以及檢討並且改良了他原本會造成用戶斷線的問題。我們設計了一個演算法去取代這篇研討會期刊的演算法有問題的部分。並且最後我們根據模擬數據，來討論應該如何適當地調整我們的演算法之中的參數。

In 3GPP Long-Term Evolution-Advanced (LTE-A) systems, coordinated multi-point (CoMP) has been shown to be a promising technique to mitigate inter-cell interference. Radio resource allocation is an important part of CoMP technique. We focus on a conference paper which is about radio resource allocation, and do discussions and comparisons. We improve its unfair problem that makes many users in the central region idle by designing an algorithm to replace the problematical part. Finally, we discuss how to choose appropriate values for a parameter in our algorithm basing on simulation result.
