Abstract

La présente invention concerne un appareil et un procédé de rapport de faisceau d'ondes, ainsi qu'un dispositif de communication. Le procédé de rapport de faisceau d'ondes est appliqué à un dispositif côté réseau. Le procédé consiste à envoyer des premières informations de configuration d'un signal de référence à un terminal ; les premières informations de configuration comprennent un signal de référence utilisé pour la gestion de faisceau d'ondes, et une correspondance existant entre le signal de référence et un point de réception de transport (TRP).
