Soft Frequency Reuse for Inter-Cell Interference Co-Ordination in LTE Based Cellular Network
In Third Generation Partnership Project (3GPP) Long Term Evolution (LTE), the frequency planning with reuse of one is aim to provide high bandwidth service to the user but such a frequency planning strategy can lead to unacceptable inter-cell interference levels experienced especially by users located at the cell edge area. In this paper, two methods, Fractional Frequency Reuse (FFR) and Soft Frequency Reuse (SFR) are proposed as interference management scheme in order to enhance overall per user Quality of Service (QoS) and throughput as per basis on Signal-to-Interference plus Noise Ratio (SINR) metrics.
