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 (CSI 1 ) 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 (CSI 2 ) comprising the CSI of a subcarrier whose SNR variation amount is equal to or greater than the threshold value.
