摘要：Long-Term Evolution (LTE), an emerging and promising fourth generation mobile technology, is expectedto offer ubiquitous broadband access to the mobile subscribers. In this paper, the performance of FrameLevel Scheduler (FLS), Exponential (EXP) rule, Logarithmic (LOG) rule and Maximum-Largest WeightedDelay First (M-LWDF) packet scheduling algorithms has been studied in the downlink 3GPP LTE cellularnetwork. To this aim, a single cell with interference scenario has been considered. The performanceevaluation is made by varying the number of UEs ranging from 10 to 50 (Case 1) and user speed in therange of [3, 120] km/h (Case 2). Results show that while the number of UEs and user speed increases, theperformance of the considered scheduling schemes degrades and in both case FLS outperforms other threeschemes in terms of several performance indexes such as average throughput, packet loss ratio (PLR),packet delay and fairness index.
