The deployment of femto-cells in fifth-generation (5G) systems is necessary thanks to their advantages in terms of the number of supported users, and the reduction of energy consumption, thus it’s promising to adopt this concept to meet the 5G networks’ requirements. However, the allocation of resources and the management of traffic while maintaining the quality of service (QoS); constitutes a major challenge in terms of fairness and perceived throughput at the terminal level.In this paper, a number of scheduling algorithms planned to be used in 5G, namely the Proportional Fair (PF) algorithm, the Exponential Proportional Fair algorithm (EXP / PF) and the algorithm Maximum Largest Weighted Delay First (MLWDF) are studied and compared in terms of equity (Fairness Index), useful rate (Goodput) and spectral efficiency, at the level of femto-cells in the downward direction.
