LTE Cellular Networks Packet Scheduling Algorithms in Downlink and Uplink Transmission: A Survey

This survey paper provides a detailed explanation of Long Term Evolution (LTE) cellular network’s packet scheduling algorithms in both downlink and uplink directions. It starts by explaining the difference between Orthogonal Frequency Division Multiple Access (OFDMA) that is used transmission, Single Carrier – (SC-FDMA) uplink. Then, it explains LTE process donwlink through interaction users scheduler. most commonly analyzing their formulas, characteristics, suitable conditions for them to work in, main differences among them. covers Max Carrier-toInterference (C/I), Round Robin (RR), Proportional Fair (PF), Earliest Deadline First (EDF), Modified EDF-PF, Modified-Largest Weighted Delay (M-LWDF), Exponential Fairness (EXPPF), Token Queues Mechanism, Packet Loss Ratio (PLR), Quality Guaranteed (QG), Opportunistic (OPLF), Low Complexity (LC), LC-Delay, PF-Delay, Maximum Throughput (MT), Expansion (FME), Adaptive Resource Allocation Based Scheduling (ARABPS). Lastly, some concluding remarks.
