Abstract

Un dispositivo de estación base incluye: los medios para almacenar información de calidad indicadora del estado de canal para cada una de las estaciones de transmisión de un dispositivo de usuario; los medios de programación para crear información de programación indicadora de una planta de asignación de unidad de recursos a partir de la información de la calidad; y los medios para transmitir una señal de control de capa inferior que contiene información de programación e información de selección de antena hacia un dispositivo de usuario. La información de selección de antena indica cuál de las antenas de transmisión proporcionada en el dispositivo de usuario va a ser utilizada para realizar la transmisión. La información de selección de antena y la información de programación son ambas codificadas por canal.
