A wireless communication apparatus wherein the data amount of feedback information can be reduced, while a high throughput being maintained. In this apparatus, a CSI (Channel State Information) processing part (38) generates a CSI frame based on an SNR (Signal power to Noise power Ratio) for each of measured subcarriers, and a CSI transmission control part (39) generates a timing signal and control information required for generating the CSI frame, and controls the CSI processing part (38). The CSI processing part (38) generates a first frame (CSI1), which comprises the CSI of a subcarrier whose SNR variation amount is less than a threshold value, in a generation period that is greater than the generation period of a second frame (CSI2) comprising the CSI of a subcarrier whose SNR variation amount is equal to or greater than the threshold value.

Appareil de communication sans fil où la quantité de données des informations de rétroaction peut être réduite tout en conservant un haut débit. Dans cet appareil, une partie de traitement des CSI (Channel State Information) (38) génère une trame de CSI basée sur un SNR (Signal power to Noise power Ratio) pour chacune des sous-porteuses mesurées et une partie de commande de transmission de CSI (39) génère un signal de synchronisation et des informations de contrôle requises pour générer la trame CSI et commande la partie de traitement des CSI (38). La partie de traitement des CSI (38) génère une première trame (CSI1) qui comprend la CSI d~une sous-porteuse dont la quantité de variation de SNR est inférieure à une valeur seuil pendant une période de génération qui est supérieure à la période de génération d~une deuxième trame (CSI2) comprenant la CSI d~une sous-porteuse dont la quantité de variation de SNR est égale ou supérieure à une valeur seuil.
