Title
(EN) METHODS AND APPARATUS FOR USER EQUIPMENT-ANTICIPATED COMMON BEAM SWITCHING
(FR) PROCÉDÉS ET APPAREIL DE COMMUTATION DE FAISCEAU COMMUN ANTICIPÉE D'ÉQUIPEMENT UTILISATEUR
Abstract
(EN)
A method for user equipment-anticipated common beam switching includes receiving, by a user equipment (UE), a set of reference signals from a network controller; sending, by the UE, a measurement report to the network controller based on a first reference signal of the received reference signals; determining, by the UE, that a quantity of the first reference signal reported in the measurement report exceeds a threshold; and based thereon monitoring, by the UE, a physical downlink control channel (PDCCH) over a search space on a first control resource set (CORESET),a spatial quasi-colocation (QCL) field in a transmission configuration indication (TCI) state of the first CORESET being set to a resource index of the first reference signal.
(FR)
Un procédé de commutation de faisceau commun anticipée d'équipement utilisateur comprend la réception, par un équipement utilisateur (UE), d'un ensemble de signaux de référence en provenance d'un contrôleur de réseau; l'envoi, par l'UE, d'un rapport de mesure au contrôleur de réseau sur la base d'un premier signal de référence des signaux de référence reçus; la détermination, par l'UE, qu'une quantité du premier signal de référence rapportée dans le rapport de mesure dépasse un seuil; et sur cette base, la surveillance, par l'UE, d'un canal physique de contrôle descendant (PDCCH) dans un espace de recherche sur un premier ensemble de ressources de commande (CORESET), un champ de quasi-colocalisation spatiale (QCL) dans un état d'indication de configuration de transmission (TCI) du premier CORESET étant calé sur un indice de ressource du premier signal de référence.
