Abstract

L'invention concerne un procédé de transmission de données, un dispositif de terminal, et un dispositif de réseau. Le procédé comprend les étapes suivantes: un dispositif de terminal détermine qu'une première ressource SPS disponible est configurée à un moment de transmission actuel; le dispositif de terminal détermine s'il faut utiliser la première ressource SPS pour transmettre des données de retransmission à un dispositif de réseau. Selon les modes de réalisation de la présente invention, en déterminant s'il faut utiliser la première ressource SPS du dispositif de terminal pour transmettre des données de retransmission au dispositif de réseau, le dispositif de terminal peut améliorer la compatibilité avec l'infrastructure de système existant, permettant ainsi d'améliorer l'expérience de l'utilisateur.
