Abstract

L'invention concerne un procédé et un dispositif de mise en correspondance de signaux de référence, utilisés pour réaliser une mise en correspondance de signaux de référence d'indication d'état de canal (CSI-RS) d'au moins 16 ports, de manière à réaliser une transmission CSI-RS d'au moins 16 ports. Le procédé comprend les étapes suivantes : selon une configuration de signal de référence de N ports, déterminer qu'un signal de référence d'informations d'état de canal (CSI-RS) est mis en correspondance sur une unité de ressource RE, N étant un nombre entier supérieur à 16, une position RE, ayant un CSI-RS de N ports de la configuration de signal de référence de N ports mise en correspondance avec celle-ci, est déterminée en fonction d'une position de RE ayant un CSI-RS dans une pluralité de groupes de configurations de signaux de référence de 8 ports mis en correspondance avec celui-ci, chaque S port dans le N port est multiplexé avec S mots de code de 8 mots de code à l'aide d'un code d'étalement orthogonal à 8 bits, et la configuration de signal de référence de 8 ports est une configuration CSI-RS de 8 ports définie par 3 GPP Rel -13; et réaliser une mise en correspondance de ressources sur le CSI-RS selon la RE déterminée.
