Abstract

Una unidad base y un dispositivo identifican los espacios de búsqueda candidatos del canal de control. De acuerdo con un aspecto, la unidad base mapea la unidad remota a un conjunto de elementos de canal de control candidatos que constituyen un espacio de búsqueda candidato de canal de control para un canal de control para la unidad remota. La unidad base selecciona un canal de control que comprende uno o más elementos de canal de control a partir del conjunto de elementos de canal de control candidatos. La información de control para la unidad remota se comunica utilizando el canal de control seleccionado. De acuerdo con otro aspecto, la unidad remota utiliza una señal recibida de la unidad basepara identificar un espacio de búsqueda candidato de canal de control en el cual busca la señal de control.
