Abstract

Sistema, método y nodo para la codificacion no ambigua de canales físicos de control de enlace descendente (PDCCH) en un sistema de telecomunicaciones de Evolucion a largo plazo (LTE) a fin de eliminar errores de deteccion. El método incluye el paso de modificar una dimension de un almacenamiento intermedio excluyendo a éste al menos un bit codificado. El almacenamiento intermedio recoge los bits intercalados de una carga de trabajo de PDCCH que tiene multiples bits. La carga de trabajo de PDCCH se codifica con un codigo convolucional. Después se intercalan los bits de la carga de trabajo de PDCCH. Los bits intercalados se recogen en el almacenamiento intermedio modificado. Después los bits se seleccionan del almacenamiento intermedio modificado para su transmision.
