Title (EN) DEVICE AND METHOD FOR COMPRESSING AND/OR DECOMPRESSING CHANNEL STATE INFORMATION
(FR) DISPOSITIF ET PROCÉDÉ DE COMPRESSION ET/OU DE DÉCOMPRESSION D'INFORMATIONS D'ÉTAT DE CANAL
Abstract:
(EN) The invention relates to generating compressed channel state information and restoring the channel state information from the compressed channel state information. A computation device for compressing channel state information, CSI, representing a channel transfer function H (101) having a spatial dimension and a frequency dimension comprises a transforming unit (111) configured to perform a spatial transformation (104,109) and a frequency-to-time transformation (106, 107) subsequently and in any order on the channel transfer function H (101) to obtain a transformed channel transfer function HT (110), and a compressing unit (112, 114) configured to select values of the transformed channel transfer function HT (110) and to generate compressed channel state information, CCSI (115), based on the selected values.
(FR) L'invention concerne la production d'informations d'état de canal compressées et la restauration des informations d'état de canal à partir des informations d'état de canal compressées. Un dispositif de calcul pour compresser des informations d'état de canal (CSI), représentant une fonction de transfert de canal H (101) ayant une dimension spatiale et une dimension fréquentielle, comprend une unité de transformation (111) configurée pour effectuer une transformation spatiale (104, 109) et une transformation fréquence-temps (106, 107) par la suite et dans n'importe quel ordre sur la fonction de transfert de canal H (101) pour obtenir une fonction de transfert de canal transformée HT (110), et une unité de compression (112, 114) configurée pour sélectionner des valeurs de la fonction de transfert de canal transformée HT (110) et pour produire des informations d'état de canal compressées (CCSI) (115), en fonction des valeurs sélectionnées.
