Abstract

This paper describes the implementation of an LTE downlink simulator that is able to precisely model the fast time and frequency variations existing in a multipath channel. This is decisive to properly simulate the gains achievable by the channeldependent scheduling LTE is capable of. The aim of this study is to investigate the relationship between the throughput achieved by a base station and parameters of active users in the cell (such as SINR or speed). The ultimate goal is to obtain a model that can predict throughput as a function of a few selected parameters that characterize users’ conditions. A proportional fair scheduler is used because of its ability to maximize the BS throughput while preventing user starvation. Some conclusions are drawn on the main parameters affecting the BS throughput based on results obtained so far.
