Abstract

La présente divulgation concerne un procédé et un appareil de transmission de données, pouvant être appliqués à une technologie de communication mobile. Le procédé comprend les étapes suivantes : un dispositif terminal d'envoi détermine un spectre cible en fonction de caractéristiques de données pour des données, le spectre cible étant un spectre sous licence ou un spectre sans licence ; et utilise le spectre cible pour transmettre des données de liaison latérale. Par conséquent, lorsque le dispositif terminal d'envoi doit transmettre les données de liaison latérale, il peut être déterminé, en fonction des caractéristiques de données des données, si les données de liaison latérale sont transmises à l'aide du spectre sous licence ou du spectre sans licence, de sorte que l'applicabilité du procédé puisse être améliorée.
