Abstract

Des modes de réalisation de la présente divulgation concernent un procédé de réception/transmission d'informations de configuration d'un bloc de signal synchrone de non-définition de cellule (NCD-SSB). Le procédé est exécuté par une station de base. Le procédé consiste à : transmettre des informations de configuration d'un NCD-SSB à un terminal, les informations de configuration étant utilisées pour ordonner au terminal de réaliser, sur la base du NCD-SSB, une mesure. Dans les modes de réalisation de la présente divulgation, par comparaison avec la manière dont un terminal peut uniquement réaliser une opération de mesure sur la base d'informations de configuration d'un CD-SSB et à l'aide du CD-SSB, les informations de configuration du NCD-SSB peuvent être adaptées à la manière dont est réalisée une opération de mesure à l'aide du NCD-SSB, de sorte que le résultat de mesure de réalisation de l'opération de mesure à l'aide du NCD-SSB est plus précis.
