Abstract

Este trabajo presenta una revisión de la capa física y los algoritmos de planificación en LTE y WiMAX, como son BestCQI, PF y RR en la asignación de recursos para el enlace descendente o Downlink. Se presentan los principales criterios a tener en cuenta en los planificadores como la fairness y el rendimiento, a partir del análisis de las tramas, subtramas, señalización y sincronización que componen la capa física de LTE y WiMAX. Finalmente se presentan las conclusiones de los tres algoritmos de planificación de recursos y se muestran las debilidades y fortalezas de cada uno.
