Comparative Evaluation of Fractional Frequency Reuse (FFR) and Traditional Frequency Reuse in 3GPP-LTE Downlink

Third Generation Partnership Project Long Term Evolution (3GPP-LTE) is focusing towards aggressive frequency reuse i.e. reuse of 1 so that the authors can get maximum number (all available spectrum) within a cell. Now, the major hindrance is co-channel interference which increases dramatically due to nearby adjacent co-channel cell and most especially for cell edge users. Traditional frequency reuse concept for interference management doesn't provide satisfactory coverage and rate. In this paper, FFR is purposed as a candidate for interference management and its comparative evaluation over Traditional frequency reuse on the basis of two parameter metrics viz. probability of coverage and probability of acceptance rate is done.
