Abstract

Una estación base maximiza una tasa de transmisión de datos de enlace ascendente de múltiples unidades móviles tratadas por la estación base como un transmisor de enlace ascendente sencillo virtual. La estación base identifica un conjunto de estaciones móviles como un conjunto de transmisión candidato y determina una potencia de transmisión admisible de las estaciones móviles en el conjunto de transmisión candidato. Un subconjunto de estas estaciones móviles en el conjunto de transmisión candidato se identifica.. Las tasas de transmisión de datos de enlace ascendente se asignan y comunican al subconj unto de estaciones móviles en el conjunto de transmisión candidato para optimizar un número total de bits procesados por la estación base asociada con las transmisiones de enlace ascendente recibidas del subconjunto de estaciones móviles candidato. La optimización puede lograr uno o más objetivos además de optimizar el número total de bits procesados.
