Abstract

La présente invention a trait au domaine des communications. L'invention concerne un procédé de mesure de signal de référence, un dispositif terminal et un dispositif de réseau. Le procédé selon l'invention consiste : à ne pas mesurer un signal de référence cible au cas où le signal de référence cible est configuré sur une bande de fréquence sans licence ou une bande de fréquence faisant fonctionner un mécanisme d'accès à partage de spectre; ou à mesurer un signal de référence cible au cas où une position dans le domaine temporel d'au moins une SSB cible dans un groupe de SSB candidates et une position dans le domaine temporel du signal de référence cible satisfont à une relation de position prédéfinie, le groupe de SSB candidates étant associé au signal de référence cible.
