Abstract

Se describe un dispositivo de usuario utilizando un sistema de comunicaciones que realiza el control de retransmisión automática sincrónica o no sincrónica (ARQ), que recibe un canal de control de enlace descendente y que prepara un canal de datos de enlace ascendente y un canal de control de enlace ascendente que lo acompaña. Un paquete de retransmisión es preparado de acuerdo a la información de verificación de la transmisión. El canal de control de enlace ascendente incluye la información de nuevo-viejo que indica si el paquete transmitido por el canal de datos de enlace ascendente es un paquete de retransmisión, pero no incluye la información del formato de transmisión que contiene al menos un tipo de modulación de datos utilizado en el canal de datos de enlace ascendente. El canal de control de enlace ascendente puede contener o puede no contener la información del formato de retransmisión que indica cómo es derivado el paquete de transmisión a partir del paquete transmitido. El canal de control de enlace descendente puede contener información de asignación de recursos para el canal de datos de enlace ascendente y la información de reconocimiento de transmisión codificada por canal.
