Abstract

Un planificador de asignación de recurso tiempo-frecuencia (18) para planificar la asignación de recursos de tiempo-frecuencia para mantener enlaces de comunicación desde un transmisor común (TX) a receptores múltiples (RX₁, ..., RXK) en un sistema de comunicación OFDMA inalámbrico incluye un selector del bloque de recurso (30) configurado para seleccionar un conjunto (RBS) de bloques de recursos de tiempo-frecuencia (RB) para la transmisión de un paquete para cada enlace de comunicación. Un proveedor de mediciones de calidad del enlace de comunicación (36) está configurado para determinar una medición de la relación de ganancia a interferencia más ruido (Gₖ) para cada enlace de comunicación. Un estimador de potencia de transmisión y velocidad de transmisión (34), conectado al selector del bloque de recurso (30) y el proveedor de mediciones de calidad del enlace de comunicación (36), está configurado para estimar en forma conjunta, dentro del conjunto seleccionado de bloques de recursos de tiempo-frecuencia, potencia de transmisión (Pₖ) y velocidad de transmisión (Rₖ) de los paquetes como funciones de las mediciones de la relación de ganancia a interferencia más ruido determinada, para al menos minimizar aproximadamente el consumo de energía del transmisor esperado.
