摘要 部分频率复用(FFR)是下一代移动通信系统中提升系统容量与边缘用户性能的核心技术之一。准动态FFR在增益与额外开销的平衡上具有明显优势,成为优化静态FFR技术的主要研究方向。本文提出了一种新的准动态FFR方案,以很低的额外开销,同时达到提高系统容量和改善边缘用户性能的目的。通过在LTE系统级仿真平台上的仿真,论文对算法的适用场景、增益和代价进行了深入分析。 The Fractional Frequency Reuse （FFR） is designed to boost both the system capacity and cell - edge users＇ serving quality for the next - generation wireless communication system. Quasi - dynamic FFR has its gain - cost tradeoff advantage, and receives great attention to enhance the per- formance of static FFR. In this paper, a new quasi - dynamic FFR algorithm is put forward, which could further increase system capacity and improve cell - edge users＇ serving quality at minimum cost. Simulation is done at a LTE system -level simulator, and the algorithm＇s potential applicability, gains and cost axe analyzed.
