LTE uplink analysis using two packet scheduling models

Abstract

This paper proposes the evaluation of LTE (Long Term Evolution) uplink performance using time and time-frequency domain Round Robin packet scheduling. In the analysis performed two types of non-real time services are considered, in both different and equal priorities cases. The number of users served in time-frequency domain packet scheduling strategy is limited by the number of PDCCHs (Physical Downlink Control Channel) and the results obtained take into account this constraint. Cell throughput, average user throughput and cell capacity are the performance indicators delivered by the simulations based on various scenarios of traffic, service priority and packet scheduling algorithms.
