Title (EN) METHOD OF TRANSMITTING CHANNEL STATE INFORMATION-REFERENCE SIGNAL (CSI-RS), BASE STATION, AND USER EQUIPMENT
(FR) PROCÉDÉ DE TRANSMISSION D'UN SIGNAL DE RÉFÉRENCE D'INFORMATIONS D’ÉTAT DE CANAL (CSI-RS), STATION DE BASE ET ÉQUIPEMENT UTILISATEUR
Abstract:
(EN) A method of transmitting Channel State Information (CSI)-Reference Signals (RSs) in a wireless communication system that includes a base station (BS) and a user equipment (UE) includes transmitting, from the BS to the UE, first multiple CSI-RSs in a CSI-RS resource set that consists of CSI-RS resources. The first multiple CSI-RSs are transmitted using the CSI-RS resources, respectively. The CSI-RS resource set is repeated in a time domain or a frequency domain. The transmitting transmits second multiple CSI-RSs in the repeated CSI-RS resource set.
(FR) Un procédé de transmission de signaux de référence (RS) d'informations d'état de canal (CSI) dans un système de communication sans fil comprenant une station de base (BS) et un équipement utilisateur (UE) consiste à transmettre, de la BS vers l'UE, des premiers CSI-RS multiples dans un ensemble de ressources CSI-RS qui est constitué de ressources CSI-RS. Les premiers CSI-RS multiples sont transmis à l'aide des ressources CSI-RS, respectivement. L'ensemble de ressources CSI-RS peut être répété dans un domaine temporel ou dans un domaine fréquentiel. La transmission transmet des seconds CSI-RS multiples dans l'ensemble de ressources CSI-RS répété.
