PHY-MAC cross layer based modelling for LTE QoS optimization

Abstract

We study two cross layer simulation models with different LTE MAC scheduler types in this paper: a discrete time simulation model and a discrete event simulation model. Results show that under similar settings, these two simulation models produce similar results in a single user scenario but perform differently in a multi-UE scenario. Moreover, the proportional fair scheduling is shown to be the fairest one using both simulation models.
