Abstract

Un método para gestionar órdenes de canal de control de enlace descendente físico, denominado PDCCH en lo sucesivo en el presente documento, en un equipo de usuario, denominado UE en lo sucesivo en el presente documento, de un sistema de comunicación inalámbrica, soportando el sistema de comunicación inalámbrica una agregación de portadoras, denominada CA en lo sucesivo en el presente documento, lo que permite al UE realizar una transmisión y/o una recepción a través de múltiples portadoras, comprendiendo el método: - configurar una pluralidad de portadoras (402); - recibir una orden de PDCCH (404); y - usar una portadora específica dentro de la pluralidad de portadoras para activar un procedimiento de acceso aleatorio, denominado RA en lo sucesivo en el presente documento, de acuerdo con la orden de PDCCH (406); caracterizado por que - la recepción de la orden de PDCCH consiste en recibir la orden de PDCCH a través de una portadora de enlace descendente dentro de la pluralidad de portadoras, - la portadora específica es una portadora de enlace ascendente dentro de la pluralidad de portadoras correspondiente a la portadora de enlace descendente.
