Abstract

Método y nodo de red para la configuración de ventanas de contienda en un sistema de comunicaciones inalámbrico de múltiples portadoras que implementa un protocolo ‘escuchar antes de hablar’, De acuerdo con un aspecto, el método incluye la determinación de al menos una portadora de componentes (CC) de múltiples CC para servir como un canal de retardo. El método además incluye la realización de un procedimiento ‘escuchar antes de hablar’ en la al menos una CC que sirve como un canal de retardo. El procedimiento ‘escuchar antes de hablar’ incluye detectar en cada canal de retardo si existe un canal libre durante un período de retardo procedente de una ventana de contienda (CW). El procedimiento LBT también incluye diferir la transmisión en una CC en la cual la detección no indica si existe un canal libre. El procedimiento LBT también incluye transmitir en una CC en la cual la detección indica que existe un canal libre. El método también incluye la determinación de un tamaño de la CW sobre la base de al menos un valor de realimentación de transmisión.
