(EN) SYSTEM AND METHOD FOR BEAM MANAGEMENT
(FR) SYSTÈME ET PROCÉDÉ DE GESTION DE FAISCEAU
Abstract
(EN)
A first apparatus may communicate with a user equipment through a first active beam. The first apparatus may determine that beam tracking is to be performed with the UE, including identifying a new beam for communication between the UE and the apparatus. The first apparatus may perform beam tracking with the UE based on the determination that beam tracking is to be performed. The first apparatus may communicate with the UE through a second active beam based on the beam tracking.

(FR)
Selon l’invention un premier appareil peut communiquer avec un équipement d’utilisateur au moyen d’un premier faisceau actif. Le premier appareil peut déterminer que le suivi de faisceau doit être effectué avec l’UE, dont l’identification d’un nouveau faisceau pour la communication entre l’UE et l’appareil. Le premier appareil peut procéder au suivi de faisceau avec l’UE sur la base de la détermination selon laquelle le suivi de faisceau doit être effectué. Le premier appareil peut communiquer avec l’UE au moyen d’un deuxième faisceau actif sur la base du suivi de faisceau.
