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。
Partial Frequency Reuse (FFR) is one of the core technologies for improving system capacity and edge user performance in the next generation of mobile communication systems. Quasi-dynamic FFR has obvious advantages in balance between gain and overhead, and becomes the main research direction for optimizing static FFR technology. In this paper, we propose a new quasi-dynamic FFR scheme that achieves the goal of improving system capacity and improving edge user performance with low overhead. Through simulation on LTE system-level simulation platform, the thesis analyzes the applicable scenarios, gains and costs of the algorithm in-depth.
