Abstract

Un aparato que comprende: circuitería de generador (842) adaptada para generar información de control de enlace descendente, DCI, según un formato de DCI, que incluye un campo indicador de portadora, CIF; y circuitería de transmisor (832), acoplada con la circuitería de generador, adaptada para transmitir la DCI según el formato de DCI a un equipo de usuario, UE, en el que el CIF es para planificar una pluralidad de portadoras componentes, CC, con una portadora única, y incluye bits Y, donde Y = ceiling(log2 X) +1, donde X es un número de la pluralidad de CC planificadas mediante la portadora única pero sin incluir la portadora única, en el que el UE es un primer UE, la DCI es la primera DCI, el formato de DCI es el primer formato de DCI, el CIF es el primer CIF, y la circuitería de generador (842) está además adaptada para generar la segunda DCI, según un segundo formato de DCI, que incluye un segundo CIF; y la circuitería de transmisor (832) está adaptada para transmitir la segunda DCI según el segundo formato de DCI a un segundo UE, en el que un número de bits en el primer CIF es mayor que un número de bits en el segundo CIF. el primer CIF incluye una pluralidad de bits que se generan mediante una combinación de bits de un campo CIF heredado y un bit más significativo, MSB, de un campo de número de procedimiento de solicitud de repetición automática híbrida, HARQ; o el segundo formato de DCI es uno de los formatos de DCI estándar utilizados en el sistema LTE 3GPP versión 12.
