Title
(EN) METHOD OF CSI REPORTING
(FR) PROCÉDÉ DE COMPTE RENDU DE CSI
Abstract
(EN) A method of Channel State Information (CSI) reporting in a wireless communication system includes performing, with a user equipment (UE), advanced CSI reporting based on a high resolution CSI feedback scheme. The advanced CSI reporting includes a beam index that identifies each of beams and amplitude of the beam corresponding to the beam index. The performing performs the advanced CSI reporting using a Physical Uplink Control Channel (PUCCH) format 3/4/5. The beam index and the amplitude are located in the PUCCH format 3/4/5. The performing performs first advanced CSI reporting and performs second advanced CSI reporting after performing the first advanced CSI reporting. The first advanced CSI reporting includes one of the beam index and the amplitude. The second advanced CSI reporting includes the beam index or the amplitude that is not included in the first advanced CSI reporting.
(FR) L'invention concerne un procédé de compte rendu d'informations d'état de canal (CSI) dans un système de communication sans fil, comprenant la réalisation, avec un équipement d'utilisateur (UE), d'un compte rendu avancé de CSI selon un schéma de rétroaction de CSI à haute résolution. Le compte rendu avancé de CSI comprend un indice de faisceau qui identifie chaque faisceau parmi des faisceaux et une amplitude du faisceau correspondant à l'indice de faisceau. La réalisation effectue le compte rendu avancé de CSI en utilisant un format 3/4/5 de canal physique de commande de liaison montante (PUCCH). L'indice de faisceau et l'amplitude sont situés dans le format 3/4/5 de PUCCH. La réalisation effectue un premier compte rendu avancé de CSI et effectue un deuxième compte rendu avancé de CSI après avoir effectué le premier compte rendu avancé de CSI. Le premier compte rendu avancé de CSI comprend un paramètre parmi l'indice de faisceau et l'amplitude. Le deuxième compte rendu avancé de CSI comprend celui de l'indice de faisceau et de l'amplitude qui n'est pas compris dans le premier compte rendu avancé de CSI.
