Abstract

L'invention concerne un procédé et un appareil de mesure de porteuse. Le procédé de mesure de porteuse dans la présente invention peut comprendre : un dispositif de réseau qui envoie un premier message à un dispositif terminal, le premier message comprenant des premières informations, les premières informations étant utilisées pour indiquer au moins une fréquence cible et la ou les fréquences cibles pouvant comprendre une première fréquence cible et une seconde fréquence cible ; le dispositif terminal effectue une mesure périodique à la première fréquence cible ; et lorsque le dispositif terminal passe en mode connecté, le dispositif terminal envoie un résultat de mesure de la première fréquence cible au dispositif de réseau, ce qui permet d'établir rapidement le CA ou CC sur la base du résultat de mesure. Dans la présente invention, un dispositif terminal peut distinguer différentes fréquences cibles et améliorer les performances de mesure d'une première fréquence cible, de manière à assurer la validité et la précision d'un résultat de mesure de la première fréquence cible, de telle sorte qu'un dispositif de réseau configure avec précision une porteuse secondaire ou une porteuse secondaire primaire pour le dispositif terminal sur la base du résultat de mesure, répondant ainsi aux exigences de NR pour des performances telles qu'un taux de transmission de données élevé et un faible retard.
