Title (EN) SYSTEM AND METHOD FOR FLEXIBLE CHANNEL STATE INFORMATION-REFERENCE SIGNAL TRANSMISSION
(FR) SYSTÈME ET PROCÉDÉ D’ÉMISSION FLEXIBLE D’UN SIGNAL DE RÉFÉRENCE D'INFORMATIONS D'ÉTAT DE CANAL
Abstract:
(EN) System and method for flexible channel state information-reference signal transmission A method by a wireless device is provided for restricting channel state information (CSI) measurement. The method includes receiving, from a network node, information identifying a first subset of channel state information-reference signal (CSI-RS) resources to be used in performing CSI measurements. The first subset of CSI-RS resources are associated with a first portion of a frequency band that is less than all of the frequency band. CSI measurements are performed in the first subset of CSI-RS resources that are associated with the first portion of the frequency band.
(FR) L'invention concerne un système et un procédé d'émission flexible d'un signal de référence d'informations d'état de canal. Un procédé exécuté par un dispositif sans fil permet de limiter la mesure d'informations d'état de canal (CSI). Le procédé comprend une étape consistant à recevoir d'un nœud de réseau des informations identifiant un premier sous-ensemble de ressources d'un signal de référence d'informations d'état de canal (CSI-RS) devant être utilisées pour effectuer des mesures de CSI. Le premier sous-ensemble de ressources de CSI-RS est associé à une première partie d'une bande de fréquences qui est inférieure à la totalité de la bande de fréquences. Des mesures de CSI sont effectuées dans le premier sous-ensemble de ressources de CSI-RS qui est associé à la première partie de la bande de fréquences.
