Abstract

L'invention concerne un procédé et un dispositif de communication cellulaire de bande étroite. Un équipement utilisateur (UE) reçoit premièrement un premier signal sans fil, puis envoie un deuxième signal sans fil et un troisième signal sans fil. Le premier signal sans fil est utilisé pour déterminer le deuxième signal sans fil, et le deuxième signal sans fil comprend les unes ou les autres parmi {des premières informations, des premières données}. L'expéditeur du premier signal sans fil est un premier nœud, et un récepteur du second signal sans fil comprend un second nœud. Les premières informations sont générées sur une couche physique, et les premières données sont générées sur une couche élevée. Selon la présente invention, un UE est autorisé à déterminer un contenu à envoyer de sa propre initiative, et ainsi, des ressources d'interface radio de liaison montante peuvent être utilisées de manière plus efficace, et l'efficacité de transmission est améliorée. En outre, un UE de relais mesure et rapporte des informations pertinentes concernant la qualité de canal d'une liaison de dérivation, et l'efficacité de spectre de fréquences est améliorée de façon à améliorer les performances globales d'un système.
