Title
(EN) FLEXIBLE UPLINK BEAM MANAGEMENT
(FR) GESTION DE FAISCEAU DE LIAISON MONTANTE FLEXIBLE
Abstract
(EN)
According to some embodiments, a method performed by a wireless device of transmitting in an uplink radio beam comprises: obtaining a spatial domain filter to be used for uplink transmission; determining a spatial orientation of the wireless device has changed after obtaining the spatial domain filter to be used for uplink transmission; updating the spatial domain filter to be used for uplink transmission based on the changed spatial orientation of the wireless device; and transmitting an uplink beam using the updated spatial domain filter.

Selon certains modes de réalisation, un procédé mis en œuvre par un dispositif sans fil de transmission dans un faisceau radio de liaison montante consiste à : obtenir un filtre de domaine spatial à utiliser pour une transmission de liaison montante ; déterminer une modification d'orientation spatiale du dispositif sans fil après l'obtention du filtre de domaine spatial à utiliser pour une transmission de liaison montante ; mettre à jour le filtre de domaine spatial à utiliser pour une transmission de liaison montante sur la base de l'orientation spatiale modifiée du dispositif sans fil ; et transmettre un faisceau de liaison montante à l'aide du filtre de domaine spatial mis à jour.
