ciency. The evaluation of the IMT-Advanced candidate technologies (i.e., LTE-Advanced and IEEE 802.16m) followed the following principles [6]: 1. Use of reproducible methods including computer simulation, analytical/theoretical approach, and inspection; 2. Technical evaluation against performance targets that were set for each test environment; 3. Consistency between self-evaluations and technical descriptions provided in technology description templates; 4. Use of unified methodology, software, and common parameter sets by the evaluation groups including channel models, link-level parameters, and link-to-system mapping; 5. Evaluation of multiple proposals using one simulation platform by each evaluation group to ensure comparability of the results; 6. Inclusion of L1/L2 overhead in the evaluation of cell spectral efficiency, cell edge user spectral efficiency, and VoIP capacity; 7. Independent drop of users with uniform distribution over the coverage area where each mobile user corresponds to an active session that runs for the duration of the drop; 8. Random assignment of LoS and NLoS path loss models to the users; Mobile WiMAX. DOI: 10.1016/B978-0-12-374964-2.10012-8 Copyright © 2011 Elsevier Inc. All rights reserved. CHAPTER 12 Performance of IEEE 802. 16m and 3GPP LTE-Advanced 9. Cell assignment to a user based on the air interface cell selection schemes; 10. Fading signal and fading interference computed from each mobile station into each cell and from each cell into each mobile station (in both directions on an aggregated basis); 11. Consideration of the Interference over Thermal (IoT) constraint in the uplink design, such that the average IoT value remains less than or equal to 10 dB; 12. In the full-buffer traffic model, packets are not blocked upon their arrival, i.e., buffer sizes are assumed to be infinite; 13. Data and VoIP packets are scheduled with appropriate packet schedulers for full buffer and VoIP traffic models separately; 14. Modeling of channel quality feedback delay, feedback channel error
