Title (EN) CHANNEL STATE INFORMATION FRAMEWORK DESIGN FOR 5G MULTIPLE INPUT MULTIPLE OUTPUT TRANSMISSIONS
(FR) CONCEPTION D'INFRASTRUCTURE D'INFORMATIONS D'ÉTAT DE CANAL POUR TRANSMISSIONS À ENTRÉES MULTIPLES ET SORTIES MULTIPLES 5G
Abstract:
(EN) A user equipment can be configured to decompose a multiple input multiple output (MIMO) channel into multiple domains, measure the channel state information reference signal (CSI-RS) for each domain, and select a feedback format for transmission to network node based on the measurements and a list of feedback formats. The network node can use the feedback to determine transmission parameters to be transmitted to the user equipment.
(FR) Un équipement utilisateur peut être conçu pour : décomposer un canal à entrées multiples et sorties multiples (MIMO) en multiples domaines ; mesurer le signal de référence d'informations d'état de canal (CSI-RS) pour chaque domaine ; et sélectionner un format de rétroaction pour une transmission à un nœud de réseau sur la base des mesures et d'une liste de formats de rétroaction. Le nœud de réseau peut utiliser la rétroaction pour déterminer des paramètres de transmission devant être transmis à l'équipement utilisateur.
