Abstract

L'invention concerne un procédé et un dispositif destinés à être utilisés dans un nœud de communication d'une communication sans fil. Le procédé comprend les étapes suivantes : le noeud de communication reçoit des premières informations ; déterminer un intervalle de mesure cible qui est l'un des X intervalles de mesure alternatifs ; envoyer un premier signal qui occupe un bloc de ressources temps-fréquence cible ; surveiller un premier type de signalisation dans une fenêtre temporelle cible. Les X intervalles de mesure alternatifs présentent une correspondance biunivoque avec X longueurs d'intervalle de temps, respectivement. Les premières informations sont utilisées pour déterminer la longueur d'intervalle de temps correspondant à chacun des X intervalles de mesure alternatifs. La longueur d'intervalle de temps entre le point de départ et le point de référence de la fenêtre temporelle cible est égale à une longueur d'intervalle de temps cible qui est la longueur d'intervalle de temps correspondant à l'intervalle de mesure cible dans les X longueurs d'intervalle de temps. La position du bloc de ressources temps-fréquence cible dans un domaine temps-fréquence est utilisée pour déterminer le point de référence. La présente invention améliore les performances d'accès aléatoire.
