WIRELESS COMMUNICATION APPARATUS AND WIRELESS COMMUNICATION METHOD |
摘要 |
<p>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.</p> |
