LTE network Interference Mitigation using Scheduling Schemes for Femto to Macro Interference coordination

Abstract

Interference is one of the most common problems that occur in the LTE network and its causes are interference signals inseveral paths, noise and others.In this research, the femto to macro interference was reduced by using coordination methods for time and frequency scheduling algorithms based on priority user. Two scenarios were developed including urban and suburban areas. The coordination algorithms were applied to them. The best performance for SINR and Throughput was calculated by calculating some equations using the Mat lab program.Simulation result using ICIC methods can improve SINR performance 25 dBin urban and 27 dB in suburban, throughput performance 0.77 Mbps in urban and 1.83 Mbpsin suburban.eICIC methods can improve SINR performance 22 dB inurban and 29 dB in suburban, throughput performance 2.47 Mbps in urban and 5.3 Mbpsin suburban. The result proved using eICIC method in time domain resource have better performance than using ICIC method in frequency resource. However using eICIC method in suburban deployment scenario can increase the performance of SINR and throughput more effective than using ICIC method in urbanthe scenarios were compared and the suburban scenario was found to be better than the urban scenario.
