Abstract

Les modes de réalisation de la présente invention concernent un procédé et un dispositif de programmation d'une demande, appartenant au domaine des communications, et autorisant l'UE à déterminer avec précision s'il faut déclencher une demande de programmation, et éviter des retards de données provoqués par la demande de programmation qui n'est pas déclenchée dans les temps. Le procédé comprend les étapes suivantes : si un dispositif terminal a au moins un rapport d'état de tampon déclenché, le dispositif terminal détermine une première condition, la première condition comprenant : une première ressource de liaison montante disponible pour une nouvelle transmission est présente, la première ressource de liaison montante étant configurée par un dispositif de réseau ; et si la première condition est remplie, le dispositif de terminal déclenche une demande de programmation, la demande de programmation étant utilisée pour demander une seconde ressource de liaison montante, et la seconde ressource de liaison montante étant une ressource de liaison montante à utiliser pour la nouvelle transmission.
