Abstract

La présente invention concerne un procédé et un appareil de détermination d'un livre de codes de rétroaction, appartenant au domaine technique des communications. Dans le procédé de détermination d'un livre de codes de rétroaction, un terminal de communication détermine la taille du livre de codes de rétroaction selon un ou plusieurs des paramètres correspondant à chaque longueur de TTI : taille de fenêtre de rétroaction maximale M, retard de rétroaction minimal k, longueur de TTI pouvant être transmise sur une onde porteuse, quantité de longueurs de TTI pouvant être transmises sur l'onde porteuse, et longueur de TTI transportant des informations de rétroaction.
