Abstract

Les modes de réalisation de la présente invention concernent un procédé et un appareil de transmission d'informations de commande de liaison montante, ainsi qu'un dispositif terminal. Le procédé comprend les étapes au cours desquelles : le dispositif terminal reçoit des premières informations de configuration, les premières informations de configuration étant utilisées pour ordonner au dispositif terminal de générer au moins deux livres de codes de rétroaction, lesdits au moins deux livres de codes de rétroaction comprenant un premier livre de codes de rétroaction et un second livre de codes de rétroaction ; lorsque le dispositif terminal détermine de construire le premier livre de codes de rétroaction et/ou lorsque le dispositif terminal détermine de transmettre un premier PUCCH transportant le premier livre de codes de rétroaction, le dispositif terminal détermine de ne pas construire le second livre de codes de rétroaction et/ou le dispositif terminal détermine de ne pas transmettre un second PUCCH transportant le second livre de codes de rétroaction, le premier PUCCH et le second PUCCH étant tous deux situés dans un premier créneau temporel.
