Abstract

La presente invención está diseñada para exponer un método que puede impedir errores de desmodulación en terminales de usuario y hacer la utilización máxima de recursos cuando la transmisión de datos se lleva a cabo por medio del uso de solo una parte de los símbolos de OFDM en las subtramas. Una terminal de usuario de acuerdo con un ejemplo de la presente invención tiene una sección de recepción que acepta información acerca del número de símbolos utilizados en una subtrama determinada de una portadora donde se configura la función LBT (Escuchar Antes de Hablar), en la portadora, y una sección de control que dirige un proceso de recepción en la subtrama determinada con base en la información acerca del número de símbolos utilizados.
