Abstract

Des modes de réalisation de l'invention concernent un procédé de mesure de cellule, un procédé de réception et de mesure de signaux ainsi qu'un équipement utilisateur permettant de réduire le temps de mesure, d'effectuer une mesure rapide et de fournir une solution pour une agrégation des porteuses d'éléments de masse. Le procédé de mesure de cellule comprend les étapes suivantes : un équipement utilisateur (UE) acquiert une demande de mesure ; l'UE mesure, d'après la demande de mesure, un nombre M de cellules sur un nombre N1 de points de fréquence à mesurer, où N1 ≤ N, M < 4*n, N étant le nombre total de points de fréquence à mesurer, et N étant un nombre entier. L'invention peut s'appliquer au domaine technique des communications sans fil.
