Chapter 12 - Performance of IEEE 802.16m and 3GPP LTE-Advanced

Abstract

Link-level and system-level simulations are used to evaluate the performance of mobile radio access technologies under various operating conditions and deployment scenarios. While the simulations do not model the entire deployment parameters and propagation conditions that may be involved in a practical scenario due to increased computational complexity of the model, the statistical modeling of the parameters and estimation/measurement errors should be sufficiently accurate such that the simulation results are a faithful representative of the performance in an actual deployment. The evaluation of the IMT-Advanced candidates was comprehensively performed in strict compliance with the technical parameters and the methodology that were specified by the ITU-R. Each requirement is independently evaluated, except for the cell and cell edge user spectral efficiencies criteria that were jointly assessed using the same system-level simulation, and consequently the candidates were required to simultaneously satisfy the corresponding minimum requirements. Furthermore, the system-level simulation set-up used in the assessment of the mobility requirement was the same as that used for the evaluation of cell spectral efficiency and cell edge user spectral efficiency.
