Abstract

Selon des modes de réalisation, la présente invention concerne un procédé d'attribution de ressources et un appareil associé. Le procédé comprend les étapes suivantes : un équipement utilisateur détermine son nombre de faisceaux de réception disponibles, et envoie des informations d'indication du nombre de faisceaux de réception à un dispositif de réseau, ces informations d'indication indiquant le nombre de faisceaux de réception disponibles de l'équipement utilisateur ; et le dispositif de réseau reçoit les informations d'indication du nombre de faisceaux de réception qui sont envoyées par l'équipement utilisateur, et attribue des ressources de signaux de référence de gestion de faisceaux en fonction du nombre de faisceaux de réception disponibles de l'équipement utilisateur et du nombre de faisceaux d'envoi du dispositif de réseau. L'utilisation des modes de réalisation de la présente invention permet d'attribuer de manière spécifique des ressources de signaux de référence de gestion de faisceaux, de réduire les surdébits de signalisation de rapport, ou d'économiser les ressources sans fil.
