Abstract

La présente demande concerne un procédé de traitement, un dispositif de communication et un support de stockage. Le procédé de traitement comprend les étapes consistant à : déterminer un budget de ressources d'au moins une occasion de surveillance de canal dans au moins une combinaison de groupes de créneaux (S10) ; et régler au moins un ensemble d'espaces de recherche sur la base du budget de ressources (S20). Dans la solution technique de la présente demande, l'ensemble d'espaces de recherche est réglé sur la base du budget de ressources de l'occasion de surveillance de canal dans la combinaison de groupes de créneaux temporels, de façon à permettre à l'ensemble d'espaces de recherche réglé d'être mis en correspondance avec la capacité de traitement d'un terminal mobile, réduisant ainsi la complexité du décodage aveugle de PDCCH, et/ou résolvant le problème selon lequel un terminal mobile ne peut pas effectuer un décodage de PDCCH correspondant dans un temps défini.
