Abstract

The demand on mobile Internet related services has increased the need for higher bandwidth in fifth generation cellular networks (5G). Cell densification serves as a promising candidate solution for increasing system coverage and meeting the growing demand for mobile data. However, ICI represents a real challenge that limits system performance, especially cell-edge throughput. In view of this, we propose in this paper an analysis of the scheduling algorithms PF, PF+ and RR, besides a study of the eICIC and FeICIC techniques for hetnets in the downlink LTE-A and 5G. In addition, there is an improvement in the PF scheduling algorithm. The simulation results show the advantages and limitations of the ICIC techniques and the performance of the scheduling algorithms in the analyzed scenarios.
