摘要

为了在蜂窝网络中实现高容量，采用了统一的频率复用因子。然而，它在细胞边缘区域受到严重的同信道干扰。这导致较差的信号干扰加噪声比(SINR)，因此性能差。分数频率复用(FFR)是提高小区边缘性能的方法之一。在这项工作中，我们提出了信噪比阈值和带宽划分对FFR方案成功部署的影响。我们已经考虑了实时和最佳努力流量。

Analysis of fractional frequency reuse in OFDMA networks for real time and best effort traffic

To achieve high capacity in cellular networks, frequency reuse factor of unity is used. However, it suffers from heavy co-channel interference at cell edge regions. This leads to poor Signal to Interference plus Noise Ratio (SINR) and hence poor performance. Fractional Frequency Reuse (FFR) is one of the methods being considered to improve cell edge performance. In this work we present the impact of SINR threshold and bandwidth partitioning on the successful deployment of FFR scheme. We have considered both Real Time and Best Effort traffic.
