Abstract

The Proportional Fair (PF) scheduling technique is well known technique that is used to schedule radio resources at the mobile base station to the end-users. An efficient scheduling for radio resources in the physical layer of LTE-A base stations is challenging due to the high demand for various types of 4G wireless services such as VOIP calls, online gaming, HDTV, etc. In this paper, we derive the averagethroughput window size (TPF) formulas for LTE-A PF Scheduler, and then we investigate the effect of TPF size on the performance and fairness of PF Scheduler for LTE-A network. Both of downlink system-level (SL) simulator and link-level (LL) simulator are used to evaluate the scheduler performance for different TPF configurations. The simulation results showed that the long TPF improves both of UE (User Equipment) throughput and cell (eNodeB) throughput, however the achieved scheduler fairness in this case is low. On the other hand, the short TPF showed degradation in both of UE and cell throughput, but offers higher fairness values for the PF scheduler.
