Title
(EN) BEAM INDICATION FOR UPLINK POWER CONTROL
(FR) INDICATION DE FAISCEAU POUR COMMANDE DE PUISSANCE DE LIAISON MONTANTE
Abstract
(EN)
A user equipment (UE) being configured to receive a downlink, DL, information; determine a spatial association for an uplink, UL, transmission based on the DL information; and determine UL power control, PC, parameters based on the DL information.
(FR)
Un équipement utilisateur (UE) est configuré pour recevoir des informations de liaison descendante (DL) ; déterminer une association spatiale pour une transmission de liaison montante (UL) sur la base des informations DL ; et déterminer des paramètres de commande de puissance (PC) UL sur la base des informations DL.
