Title
(EN) ROBUST BEAM FAILURE RECOVERY USING A NON-SERVING CELL
(FR) REPRISE SUR DÉFAILLANCE DE FAISCEAU ROBUSTE À L'AIDE D'UNE CELLULE NON DE DESSERTE
Abstract
(EN)
A UE, in response to a beam failure being detected for a serving cell that serves the user equipment, determines whether a timer is running. One of the following is performed by the UE: in response to the timer running, a beam failure recovery procedure with a target non-serving cell; or in response to the timer not running, a beam failure recovery procedure with the serving cell. Methods, apparatus, computer programs, and computer program products are disclosed.
(FR)
Un UE, en réponse à une défaillance de faisceau détectée pour une cellule de desserte qui dessert l'équipement utilisateur, détermine si un temporisateur est en cours d'exécution. L'une des actions suivantes est effectuée par l'UE : en réponse à l'exécution du temporisateur, une procédure de reprise sur défaillance de faisceau avec une cellule non de desserte cible ; ou en réponse au temporisateur ne s'exécutant pas, une procédure de reprise sur défaillance de faisceau avec la cellule de desserte. L'invention concerne des procédés, un appareil, des programmes d'ordinateur, et des produits-programmes d'ordinateur.
