Abstract

L'invention concerne un appareil et un procédé de communication. Le procédé de communication d'un équipement utilisateur (UE) consiste à recevoir un premier signal de référence d'informations d'état de canal (CSI-RS) et/ou un second CSI-RS en provenance d'une station de base, le premier CSI-RS et/ou le second CSI-RS étant situés dans une zone de mesure. Cela peut fournir une configuration et un procédé de mesure de faisceau.
