Abstract

Des modes de réalisation de la présente invention concernent un procédé de positionnement relatif, un dispositif électronique, un appareil et un support d'enregistrement. Le procédé comprend les étapes suivantes : un premier UE terminal diffuse un message de positionnement relatif ; et le premier UE effectue un positionnement relatif au moyen d'une interface entre le premier UE et un second UE, le second UE étant un UE déterminant la prise en charge d'un processus de positionnement relatif du premier UE après la réception du message de positionnement relatif. Selon des modes de réalisation de la présente invention, l'UE est supporté par un UE voisin pour effectuer un positionnement relatif, de sorte qu'une erreur de positionnement relative entre les UE est réduite lorsqu'un module de positionnement par satellite ne peut pas être utilisé ou qu'une erreur de la position absolue déterminée au moyen du module de positionnement par satellite de l'UE est importante.
