Abstract

Des modes de réalisation de la présente demande divulguent un procédé et un appareil de gestion de faisceau. Le procédé comprend les étapes suivantes : par un dispositif terminal, recevoir des premières informations d'indication envoyées par une station de base, les premières informations d'indication étant utilisées pour indiquer que l'état de faisceau d'un faisceau de station de base est changé ; et en réponse à la détermination, selon les premières informations d'indication, que l'état de faisceau du faisceau de station de base est changé, mesurer à nouveau un signal pilote correspondant au faisceau de station de base pour obtenir un résultat de mesure, et rapporter le résultat de mesure à la station de base. En mettant en œuvre les modes de réalisation de la présente demande, la station de base est supportée pour envoyer activement les premières informations d'indication au dispositif terminal, indiquant que l'état de faisceau du faisceau de station de base est changé, et le dispositif terminal n'a pas besoin d'effectuer une mesure de liaison descendante, de déterminer une défaillance de faisceau, puis de rapporter un processus de découverte de défaillance de faisceau ; ainsi, le retard de transmission peut être réduit, et le surdébit de signalisation peut être réduit.
