Abstract

L'invention porte sur un procédé d'envoi d'informations, un procédé de réception d'informations et un dispositif associé, de nature à résoudre le problème de comment envoyer ou recevoir un CSI-RS pour réduire le brouillage. Le procédé comprend les opérations suivantes : un UE acquiert des premières informations de configuration concernant un CSI-RS commun, les premières informations de configuration étant utilisées pour indiquer la transmission d'un premier ensemble d'unités de ressource du CSI-RS commun ; l'UE détermine de transmettre au moins une première ressource d'un canal commun, la première ressource comprenant le premier ensemble d'unités de ressource du CSI-RS commun ; et l'UE reçoit le canal commun sur la première ressource en laissant de côté le premier ensemble d'unités de ressource. Le dispositif comprend une station de base ou un équipement utilisateur (UE). La solution technique peut éviter le brouillage d'un CSI-RS commun sur un canal commun, et peut, au moyen des premières informations de configuration concernant le CSI-RS commun, étendre des ressources CSI-RS.
