Abstract
The project to define Long Term Evolution (LTE) of UMTS cellular technology started in year 2004 is well established to the world. The subsequent evolve of LTE-Advanced however targets for enhancement in average spectrum efficiency and cell-edge user throughput. The limiting factor of the system performance at cell-edge is inter-cell interference (ICI). The challenge that is discussed in this paper focuses on ensuring the overall satisfaction mainly cell-edge system performance through the analysis on Fractional Frequency Reuse (FFR) and hybrid Macro system which involves small cell technology - Femtocell technology. This paper discussed the three frequency allocation schemes. The schemes include without the application of Femtocell, with randomly application of Femtocell and with preplanned Femtocell scheme. The FFR mechanism divides the cell into two regions (inner and outer). The inner radius and inner region resource is determined base on overall average throughput and overall user satisfaction.
从2004年开始的UMTS移动通信技术LTE (Long Term Evolution,长期演进)的定义事业,在世界范围内已经确立。然而,LTE-Advanced的后续发展目标是提高平均频谱效率和蜂窝边缘用户吞吐量。小区间干扰是影响系统性能的主要因素。本文通过分析分数频率复用(FFR)和混合宏系统(涉及小蜂窝技术-飞蜂窝技术),重点讨论了如何保证蜂窝边缘系统性能的总体满意度。本文讨论了三种频率分配方案。包括不使用、随机使用和预先规划的三种方案。FFR机制将细胞分为两个区域(内部和外部)。内部半径和内部区域资源是根据总体平均吞吐量和总体用户满意度确定的。
