Executive Summary

This paper presents a detailed analysis on the Long Term Evolution performance in both downlink and uplink directions emphasizing the most important aspects that influence the performance indicators. Round Robin and Weighted Round Robin scheduling strategies, in time domain and time-frequency domain, are used in different scenarios concerning antenna configuration, number of users and types of services in order to evaluate cell throughput, average user throughput and cell capacity. The control channels bring some limitations in the number of users served and on the actual transmission bandwidth when time-frequency domain packet scheduling is implemented and all these are reflected in the simulation results.
