Abstract

La présente invention concerne un procédé de calibrage d'antenne, un dispositif, un support de stockage, un système de communication et un système de puce pour calibrer une antenne d'une station de base pour réduire une erreur sur un angle d'arrivée calculé. Le procédé de calibrage d'antenne comprend : l'obtention, par un dispositif de gestion de positionnement, d'informations de localisation d'un dispositif de terminal (111) (201) ; l'envoi d'un premier message à un premier dispositif de réseau, le premier message comprenant des premières informations d'angle d'arrivée, et les premières informations d'angle d'arrivée étant déterminées selon les informations de localisation du dispositif de terminal (111) et des informations de localisation du premier dispositif de réseau (202) ; et le calibrage, par le premier dispositif de réseau, d'une antenne du premier dispositif de réseau selon les premières informations d'angle d'arrivée (204). Étant donné que le premier dispositif de réseau peut calibrer l'antenne du premier dispositif de réseau selon les premières informations d'angle d'arrivée, l'erreur sur l'angle d'arrivée calculé peut être réduite.
