Técnicas de Coordenação de Interferência Inter-Celular para Redes Heterogêneas no Downlink LTE-A

Future generation cellular networks are expected to provide broad-band access to a continuously growing number of mobile users. The densification of cellular networks is necessary to increase their capacity and improve spectral efficiency, however, in these systems, ICI still represents a real challenge that limits system performance, especially for users located at the edge of the cell. This paper briefly reviews the ICIC techniques in the downlink LTE-A of mobile cellular networks as an approach to alleviate the impact of interference and improve performance. The simulation results show the advantages and limitations of the eICIC and FeICIC techniques compared to the model without interference control.
