Abstract

La présente invention se rapporte à un procédé et à un dispositif de gestion de sous-trame flexible. Le procédé selon l'invention consiste : à indiquer un attribut de sous-trame d'une sous-trame flexible via un canal de commande physique d'indication de format (PCFICH) dans une tranche de temps pilote en liaison descendante (DwPTS), l'attribut de sous-trame comprenant un format en liaison montante ou en liaison descendante ; et à exécuter une communication sur la sous-trame flexible sur la base de l'attribut de sous-trame. La présente invention résout le problème lié au fait que la transmission de données manque d'efficacité en raison de l'incapacité à changer de façon dynamique la proportion liaison montante/liaison descendante d'une sous-trame. En cela, l'invention est apte à améliorer significativement l'efficacité d'une transmission de données.
