Abstract

L'invention concerne un procédé de transmission de données comprenant les étapes suivantes consistant à : recevoir des premières informations envoyées par une station de base ; créer une séparation de support ; transmettre, à une station de base, un rapport d'état de tampon comprenant des informations de tampon d'un premier canal logique et d'un second canal logique, et recevoir des secondes informations renvoyées par la station de base ; obtenir des informations de contrainte dans des premières informations et/ou des secondes informations, et générer une relation de contrainte conformément aux informations de contrainte, la relation de contrainte étant utilisée pour définir que le premier canal logique et le second canal logique sont respectivement mappés sur différentes porteuses ; et attribuer respectivement des ressources de différentes porteuses au premier canal logique et au second canal logique conformément à des informations de distribution et à la relation de contrainte. Selon un mode de réalisation de la présente invention, des canaux logiques non liés et des porteuses attribuées à ces canaux logiques non liés limitent simplement, au moyen de différentes porteuses, l'attribution de ressources au premier canal logique et au second canal logique ; en conséquence, lorsqu'il est détecté qu'une porteuse est encombrée ou a un problème de liaison ou d'autres problèmes, un canal logique mappé sur la porteuse peut être mis en correspondance avec une autre porteuse au moyen d'un réglage.
