Proportional equal throughput scheduler — A very fair scheduling approach in LTE downlink

Abstract

Scheduling allots the frequency and time resources of the LTE network to the users based on certain algorithms. The aim of an efficient fair scheduling is to provide the radio resources such that all the users are serviced almost equally over time without reducing the average user throughput. In this paper a fair scheduling algorithm named Blind Equal Throughput is modified and tested in different user conditions and a new scheduling scheme named Proportional Equal Throughput (PET) is developed which offers better fairness among users without reducing average user throughput, in comparison with other scheduling algorithms.
