Abstract

La présente invention concerne un procédé d'envoi de données, un terminal d'envoi de données, et une station de base. Le procédé comprend les étapes suivantes : un UE distant obtient des premières informations de support ; d'après les premières informations de support, l'UE distant envoie un paquet de données à un UE relais et/ou l'UE relais obtient des secondes informations de support ; et, d'après les secondes informations de support, l'UE relais envoie un paquet de données à l'UE distant ou à une station de base. L'invention résout ainsi le problème lié, dans l'état de la technique, au fait qu'un UE distant ou un UE relais ne peut pas envoyer normalement des données lorsque l'UE distant est connecté à l'UE relais au moyen d'une technologie d'accès non 3GPP.
