Fair boundary scheduler for LTE system

摘要

Scheduling technique plays a significant role in distributions of Resource Blocks (RBs) in LTE system. In order to ensure the LTE system operates efficiently, the scheduler needs a good trade-off between the overall cell throughput and the fairness to all the users' equipment (UEs) in its respective cell. Improving the overall cell throughput while maintaining its fairness level is very crucial in order to ensure all UEs have been served fairly and efficiently. The proposed scheduler technique, which is referred to as Fair Boundary (FB) Scheduler is shown to improve the overall cell throughput while maintaining a high level of fairness among UEs. Our simulation showed that the Fair Boundary Scheduler achieved up to 13 percent improvement in term of the overall cell throughput. Furthermore, our simulation results also showed that the proposed scheduler exhibited better fairness compared to the widely used Proportional Fair (PF) and Round Robin (RR) schedulers.
