Abstract

Une méthode de transmission dun signal par une station de base vers un relais dans un système de communication sans fil comprend létalement du signal de référence et la transmission du signal de référence étalé vers le relais dans une trame secondaire. La trame secondaire présente une première et une deuxième fentes, chacune delle comprenant une pluralité déléments de ressource consécutifs à attribuer pour la transmission du signal de référence étalé. Les éléments de ressource consécutifs sont en chevauchement avec les deux derniers symboles de multiplexage par répartition orthogonale de la fréquence (OFDM) dans chaque fente. Si un dernier symbole OFDM de la trame secondaire nest pas disponible pour la transmission vers le relais, un élément de ressource des éléments de ressource consécutifs dans un deuxième dernier symbole OFDM est utilisé pour transmettre un signal de données.
