Abstract
Se proporcionan métodos y aparatos para transmisores y receptores para conducir y recuperar información importante del sistema conducida en un sistema de modulación de múltiples portadores, para el cual, la corriente de datos se organiza en múltiples tubos de capa física (PLP). Esto es particularmente importante cuando los transmisores comparten el mismo canal físico. En un aspecto de los presentes principios, esto se logra al asignar un PLP, como un sistema PLP. El sistema llevará la información tal como la asociación entre el transmisor y sus PLP y mensajes especiales como un Sistema de Alerta de Emergencia y mensajes de Alerta Amber. En otro aspecto de los presentes principios, esta información es conducida en datos de señalización de la señal, en lugar de un PLP. En otro aspecto de los presentes principios, esto se logra por un parámetro de señalización, el cual identifica al transmisor asociado con cada PLP.
