Abstract

L'invention concerne un dispositif d'un équipement utilisateur (UE) de nouvelle radio (NR), un procédé et un support lisible par machine permettant de mettre en œuvre le procédé. Le dispositif comprend une interface radiofréquence (RF) et des circuits de traitement couplés à l'interface RF, les circuits de traitement permettant : de déterminer, avant l'établissement de connexion de commande de ressources radio (RRC), un indice de code de couverture orthogonal (OCC) d'un format de canal physique de commande de liaison montante (PUCCH) 1 en fonction d'un indice de décalage cyclique (CS) initial du PUCCH ; et d'effectuer un codage afin de transmettre le PUCCH en fonction de l'indice d'OCC. Facultativement, le PUCCH peut présenter une longueur de 10 symboles ou 14 symboles.
