Abstract

La présente invention concerne un procédé et un dispositif de mesure de faisceau, qui peuvent résoudre le problème selon lequel une grande quantité d'informations redondantes est rapportée pendant une mesure d'interférence de faisceau, entraînant ainsi un gros surdébit de rapport d'interférence, avec pour conséquence une réduction du gaspillage de ressources et une amélioration de l'efficacité de communication, et qui peuvent être appliqués à des systèmes de communication de type LTE et NR. Le procédé comprend les étapes suivantes : un dispositif terminal reçoit des informations de configuration de mesure provenant d'un dispositif réseau, les informations de configuration de mesure étant utilisées pour indiquer un ensemble CMR, un ensemble IMR, un mode de balayage de faisceau et un volume de données rapportées ; le dispositif terminal reçoit et mesure des signaux provenant du dispositif réseau sur l'ensemble CMR et l'ensemble IMR ; et le dispositif terminal détermine le contenu d'un rapport de mesure en fonction du mode de balayage de faisceau et/ou du volume de données rapportées, et envoie le rapport de mesure au dispositif réseau.
