MIGITATION OF INTER CELL INTERFERENCE AND FADING IN LTE SYSTEMS

Abstract

In this study we investigate the compensation of outage area utmost. It introduces the self optimization of the neighbors of the outage cells with antenna tilts for the generation of the most suitable configuration settings for the network with base stations/eNodeBs positional information. All the neighbors of the outage cell increase their coverage area and thus contribute to cell outage compensation. Every neighbor cell calculates the edge points of its antenna reach by propagation path loss model in order to minimize the inter-cell interference. Antenna parameter selection and optimization has an important role to achieve maximum capacity and coverage performance in LTE and beyond (LTE-A). For this reason, the LTE framework is adopted for simulations and Cell coverage extension, cell capacity enhancement and Inter-Cell Interference (ICI) mitigation provided by optimized antenna parameter investigations on the basis of specifications (TR25.814 and TR36.814). The simulation results provide strong evidence that our scheme delivers substantial gains in terms of coverage compared to existing solutions without sacrificing the SINR.
