Abstract

Certains modes de réalisation de la présente invention concernent un procédé de communication sans fil et un dispositif, au moyen desquels des performances de communication peuvent être améliorées dans l'attribution ou l'utilisation de ressources pour un PDCCH. Le procédé comporte les étapes consistant: pour une première porteuse ou une cellule ou une partie de bande passante, déterminer un premier décalage d'un ensemble de ressources de commande (CORESET) d'un terminal sur la première porteuse ou la cellule ou la partie de bande passante par rapport à une première position de ressource de référence; pour une seconde porteuse ou la cellule ou la partie de bande passante, déterminer un second décalage du CORESET du terminal sur la seconde porteuse ou la cellule ou la partie de bande passante par rapport à une seconde position de ressource de référence; et envoyer des premières informations et des secondes informations au terminal, les premières informations étant utilisées pour indiquer le premier décalage correspondant à la première porteuse, à la cellule ou à la partie de bande passante, et les secondes informations étant utilisées pour indiquer le second décalage correspondant à la seconde porteuse, à la cellule ou à la partie de bande passante.
