Title
(EN) METHOD AND DEVICE IN A NODE USED FOR WIRELESS COMMUNICATION
(FR) PROCÉDÉ ET DISPOSITIF DANS UN NŒUD UTILISÉ POUR LES COMMUNICATIONS SANS FIL
Abstract
(EN) The present disclosure provides a method and device in a node for wireless communications. A node first receives first information, and then monitors a first-type signaling in a first time-frequency-resource pool; the first information is used to determine a first candidate parameter and a second candidate parameter; a target parameter is the first candidate parameter, or a target parameter is the second candidate parameter; the first time-frequency-resource pool comprises K1 Resource Element (RE) sets, the first-type signaling occupies one of the K1 RE sets; the target parameter is used for receiving the first-type signaling; whether the first time-frequency-resource pool belongs to a first time window in time domain is used to determine whether the target parameter is the first candidate parameter or the second candidate parameter. The present disclosure associates spatial characteristics of the first time-frequency-resource pool with whether it is in the first time window or not, which ensures a more flexible spatial configuration of the control resource set, thus improving the overall performance.
(FR) La présente invention concerne un procédé et un dispositif dans un nœud pour les communications sans fil. Un nœud reçoit d'abord des premières informations, puis surveille une signalisation d'un premier type dans un premier pool de ressources temps-fréquence; les premières informations sont utilisées pour déterminer un premier paramètre candidat et un second paramètre candidat; un paramètre cible est le premier paramètre candidat, ou le paramètre cible est le second paramètre candidat; le premier pool de ressources temps-fréquence comprend K1 ensembles d'éléments de ressource (RE), la signalisation du premier type occupe l'un des K1 ensembles de RE; le paramètre cible est utilisé pour recevoir la signalisation du premier type; le fait que le premier pool de ressources temps-fréquence appartient ou non à une première fenêtre temporelle dans le domaine temporel est utilisé pour déterminer si le paramètre cible est le premier paramètre candidat ou le second paramètre candidat. La présente invention associe des caractéristiques spatiales du premier pool de ressources temps-fréquence au fait qu'il se trouve dans la première fenêtre temporelle ou non, ce qui garantit une configuration spatiale plus flexible de l'ensemble de ressources de commande, améliorant ainsi les performances globales.
