Evaluation of adaptive and non adaptive LTE Fractional Frequency Reuse mechanisms

Abstract

LTE networks are deployed to increase capacity and coverage especially for the indoor and cell-edge mobile users. However, such deployment comes with major challenges, radio resource management and inter-cell interferences. Fractional Frequency Reuse mechanism (FFR) is one of the most effective interference avoidance techniques. In this paper, we evaluate an existing adaptation process that adjusts to better network performance as users move in the network. With adaptation in place, we utilize our proposed metric to determine inner region radius and frequency allocation which generates high total cell throughput and serves maximum number of users in the network. The performance of static sectorized FFR with specific mobility model using adaptation process is evaluated using proposed metric and other metrics.
