Abstract
(EN)
A wireless device receives configuration parameters indicating: a first downlink bandwidth part for activation of a secondary cell, and a second downlink bandwidth part for transitioning from a dormant state to a non-dormant state of the secondary cell. The wireless device activates the first downlink bandwidth part in response to receiving a medium access control activation command indicating activation of the secondary cell. The wireless device transitions the secondary cell from the non-dormant state to the dormant state based on a command or a timer. The wireless device receives a downlink control information comprising a field indicating transitioning the secondary cell from the dormant state to the non-dormant state. The wireless device activates the second downlink BWP as an active downlink BWP in response to the transitioning the secondary cell to the non-dormant state.

L'invention concerne un dispositif sans fil qui reçoit des paramètres de configuration indiquant : une première partie de bande passante (BWP) de liaison descendante pour l'activation d'une cellule secondaire et une seconde partie de bande passante de liaison descendante pour le passage d'un état dormant à un état non dormant de la cellule secondaire. Le dispositif sans fil active la première partie de bande passante de liaison descendante en réponse à la réception d'une instruction d'activation de contrôle d'accès au support indiquant l'activation de la cellule secondaire. Le dispositif sans fil fait passer la cellule secondaire de l'état non dormant à l'état dormant en fonction d'une commande ou d'un temporisateur. Le dispositif sans fil reçoit des informations de commande de liaison descendante comprenant un champ indiquant le passage de la cellule secondaire de l'état dormant à l'état non dormant. Le dispositif sans fil active la seconde BWP de liaison descendante en tant que BWP de liaison descendante active en réponse au passage de la cellule secondaire à l'état non dormant.
