Abstract

Des modes de réalisation de la présente demande concernent un procédé de détermination d'informations de configuration de mesure, ainsi qu'un procédé de configuration, un terminal et un dispositif côté réseau. Le procédé de détermination comprend les étapes suivantes : un terminal obtient ou détermine des informations de différence de retard ; le terminal reçoit des premières informations envoyées par le dispositif côté réseau, les premières informations comprenant au moins une information de configuration de mesure ; et le terminal détermine, en fonction des informations de différence de retard et des premières informations, les informations de configuration de mesure utilisées pour mesurer des cellules ou des points de fréquence. Dans les modes de réalisation de la présente demande, le terminal obtient, en fonction d'une différence de retard de transmission entre le terminal et deux cellules ou deux points de fréquence, des informations de configuration de mesure correspondant à la différence de retard de transmission, puis effectue une mesure intra-fréquence ou inter-fréquence à l'aide des informations de configuration de mesure correspondant aux informations de différence de retard de façon à ce que le terminal puisse détecter correctement un SSB des cellules ou des points de fréquence.
