Abstract

Un método llevado a cabo en una estación base de identificar un ACK / NACK válido de entre una pluralidadde ACK / NACK recibidos de un UE en respuesta a un PDCCH de enlace descendente transmitido endiferentes niveles de agregación, comprendiendo el método y caracterizado por: determinar (704) 5 si se recibe más de un ACK / NACK del UE; identificar (706) un nivel de agregación de enlace descendente correspondiente al PDCCH para el cual el UEha transmitido una pluralidad de ACK / NACK; decodificar (708) todos los ACK / NACK recibidos desde el UE para todos los niveles de agregación válidosmenores que o iguales al nivel de agregación del PDCCH de enlace descendente; analizar (710) atributos asociados con cada uno de los ACK / NACK decodificados; y seleccionar (712) un ACK / NACK válido de la pluralidad de ACK / NACK en base al menos a los atributosanalizados.
