Abstract

Un procédé (1500) mis en œuvre par un équipement utilisateur, UE, (712), pour effectuer des mesures pendant des intervalles de mesure consiste à obtenir (1502) des informations indiquant une transformation entre des motifs d'intervalle de mesure simultanés. Sur la base des informations et d'une ou de plusieurs règles, l'UE effectue une transition (1504) d'une ou de plusieurs mesures réalisées sur au moins un objet de mesure d'un premier motif d'intervalle de mesure, MG1, à un second motif d'intervalle de mesure, MG2, au cours d'un temps de mesure.
