Abstract

L'invention concerne une technologie pour un nœud B de nouvelle génération (gNB) permettant de mesurer le rapport signal sur brouillage (SINR) interliaison dans un système New Radio (NR) de duplexage par répartition dans le temps (TDD) dynamique. Le gNB peut coder un signal de référence de mesure de brouillage (IM-RS) de liaison descendante, pour une transmission à un premier équipement utilisateur (UE), dans un peigne sélectionné d'une structure de peigne IFDMA. Le gNB peut décoder un IM-RS de liaison montante à partir d'un second UE reçu dans la structure de peigne IFDMA, l'IM-RS de liaison montante étant aligné temporellement avec l'IM-RS de liaison descendante. Le gNB peut déterminer le brouillage interliaison dans la structure de peigne IFDMA sur la base de l'IM-RS de liaison descendante et de l'IM-RS de liaison montante.
