Abstract

L'invention concerne un procédé de réalisation d'une transmission sur un canal à l'aide d'un spectre sans licence, ainsi qu'un dispositif de réseau et un terminal. Dans les modes de réalisation de la présente invention, un dispositif de réseau envoie au moins deux SSB à un terminal sur une première porteuse d'une première bande de fréquences, les au moins deux SSB comprenant un premier SSB et un second SSB et un premier espacement de sous-porteuse du premier SSB étant différent d'un second espacement de sous-porteuse du second SSB. Lorsque les SSB sont transmis sur un canal à l'aide d'un spectre sans licence, l'espacement de sous-porteuse approprié est ajusté et un espacement de sous-porteuse uniforme n'est plus utilisé ; par conséquent, des exigences OCB peuvent être satisfaites.
