Abstract

De acuerdo con determinadas modalidades, un método llevado a cabo por un dispositivo inalámbrico incluye recibir, desde un nodo de red, información de control de enlace descendente (DCI). El método también incluye determinar, con base en la DCI, un primer grupo de subintervalos de canal de enlace descendente para transmisiones de canal de enlace descendente. El primer grupo de subintervalos de canal de enlace descendente corresponde a un grupo de subintervalos de canal de enlace ascendente y está asociado con uno o más recursos de enlace ascendente en el grupo correspondiente de subintervalos de canal de enlace ascendente. El método incluye además la construcción de un primer libro de códigos de HARQ que comprenda retroalimentación de acuse de recibo (ACK) y/o acuse de recibo negativo (NACK) para las transmisiones de canal de enlace descendente programadas en el primer grupo de subintervalos de canal de enlace descendente. El método incluye además transmitir la retroalimentación de ACK y/o NACK, usando el uno o más recursos de enlace ascendente, de acuerdo con el primer libro de códigos de HARQ.
