Patent ID: 11476994

Abstract:
A method and a device for transmitting a PPDU in a WLAN system are proposed. Specifically, an AP generates a PPDU and transmits the PPDU to a STA. The PPDU includes an extremely high throughput (EHT)-LTF and a data field. The data field includes a pilot tone. The pilot tone is configured based on resource unit (RU) information about a broadband. When the broadband includes four 996-tone RUs based on the RU information, an index for the pilot tone is set to ±{24, 92, 158, 226, 266, 334, 400, 468, 562, 630, 696, 764, 804, 872, 938, 1006, 1048, 1116, 1182, 1250, 1290, 1358, 1424, 1492, 1586, 1654, 1720, 1788, 1828, 1896, 1962, 2030}.
