Abstract

Un dispositivo de terminal de comunicación puede enviar una petición de distribución de recurso a un dispositivo de control de comunicación sin distribuir ningún recurso dedicado para la petición de recurso. El dispositivo de terminal de comunicación es aplicado en un sistema de comunicación inalámbrica en el cual el dispositivo de control de comunicación distribuye los recursos utilizados cuando se realice la transmisión de radio a partir del dispositivo de terminal de comunicación (200) al dispositivo de control de comunicación (100). El dispositivo de terminal de comunicación incluye: una unidad de determinación (210) que establece si envía una petición de recurso al dispositivo de control de comunicación (100); y una unidad de control de señal (211) que transmite una señal utilizada para el mantenimiento de la sincronización de tiempo/frecuencia con el dispositivo de control de comunicación (100) al dispositivo de control de comunicación (100) a través de un primer procedimiento de transmisión para el mantenimiento de la sincronización. Si la unidad de determinación (210) hubiera establecido realizar una petición de recurso, la unidad de control de señal (211) transmitiría la señal al dispositivo de control de comunicación (100) mediante un segundo procedimiento de transmisión indicando la petición de recurso.
