Abstract

La présente invention se rapporte à un procédé et à un dispositif adaptés transmettre et recevoir des données sur la liaison montante dans un système de duplexage par répartition dans le temps (TDD). L'invention appartient au domaine technique des communications sans fil. Elle a pour objectif d'améliorer une couverture sur la liaison montante. Dans la présente invention : un terminal transmet un bloc de transmission de données (TB) dans N sous-trames sur la liaison montante, N étant le nombre de sous-trames sur la liaison montante qui sont incluses dans un cycle de service conformément à la configuration TDD sur la liaison montante/sur la liaison descendante qui est actuellement adoptée par le terminal ; et un côté réseau reçoit un TB de données envoyé par le terminal à partir de N sous-trames sur la liaison montante. Comme cela est décrit dans la solution technique de la présente invention, toutes les sous-trames sur la liaison montante qui sont incluses dans le cycle de service peuvent être utilisées à 100 %. Elles peuvent donc ainsi produire un gain de couverture sur la liaison montante, par rapport à la fois à un schéma de transmission par groupage avec un TTI non lié à une sous-trame et à un mécanisme de transmission par groupage avec TTI qui existe actuellement.
