(57) Abstract:
(EN): A method, performed by a user equipment (UE), of transmitting uplink data is provided. The method includes receiving, from a base station, configuration information for an uplink resource; determining a Hybrid Automatic Repeat Request (HARQ) process based on the configuration information; starting a configured grant timer (CGT) and a configured grant retransmission timer (CGRT) when uplink data corresponding to the HARQ process is transmitted; restarting the CGRT when the uplink data corresponding to the HARQ process is retransmitted; receiving, from the base station, downlink feedback information (DFI); and stopping the CGT and the CGRT based on the DFI indicating whether the base station received the uplink data.
(FR): L'invention concerne un procédé, réalisé par un équipement utilisateur (UE), de transmission de données de liaison montante. Le procédé consiste à recevoir, en provenance d'une station de base, des informations de configuration relatives à une ressource de liaison montante ; à déterminer un processus de demande de répétition automatique hybride (HARQ) sur la base des informations de configuration ; à démarrer un temporisateur d'autorisation configuré (CGT) et un temporisateur de retransmission d'autorisation configuré (CGRT) lorsque des données de liaison montante correspondant au processus HARQ sont transmises ; à redémarrer le CGRT lorsque les données de liaison montante correspondant au processus HARQ sont retransmises ; à recevoir, en provenance de la station de base, des informations de rétroaction de liaison descendante (DFI) ; et à arrêter le CGT et le CGRT sur la base des DFI indiquant si la station de base a reçu les données de liaison montante.
