Interference Issues in Future Mobile Networks

Abstract

Interference is a major impediment in communications via cellular radio networks. Future networks such as Long Term Evolution-Advanced (LTE-A) and 5G networks are no exception and interference issues are liable to degrade network performance drastically. This paper investigates methods for interference mitigation in existing mobile communication standards and proposes a novel technique for reduction of interference. A dynamic transmit power manipulation method is proposed in this work which monitors interference levels in the cellular traffic through Channel Quality Indicator (CQI) reports and maneuvers the device transmit powers according to threshold values based on Signal-to-Interference-and-Noise-Ratio (SINR). A simulation model for the proposed framework is developed to evaluate system performance and results collection.
