Comparative Evaluation of Fractional Frequency Reuse (ffr) and Traditional Frequency Reuse in 3gpp-lte Downlink

3 Generation Partnership Project Long Term Evolution (3GPP-LTE) is focusing towards aggressive frequency reuse i.e. reuse of 1 so that we 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. We observe that FFR has relatively better performance in 3GPP-LTE downlink.
