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.
