Abstract

La présente invention concerne un procédé de transmission de données, un dispositif terminal et un dispositif de réseau. Le procédé comprend les étapes suivantes : un dispositif terminal reçoit des premières informations d'indication envoyées par un dispositif de réseau ; le dispositif terminal détermine une deuxième ressource qui peut être combinée avec une première ressource pour constituer une ressource continue ; le dispositif terminal transmet des données de liaison montante conformément à la ressource continue constituée par la première ressource et la deuxième ressource. La présente invention, d'une part, utilise pleinement un RB orphelin de sorte que le taux d'utilisation des ressources est amélioré. D'autre part, étant donné que la première ressource et la deuxième ressource peuvent constituer une ressource continue, le dispositif terminal peut transmettre des données de liaison montante au moyen de la ressource continue, de façon à réduire le PAPR.
