Title:

METHOD FOR TRANSMITTING/RECEIVING SIGNAL IN WIRELESS LAN SYSTEM AND DEVICE THEREFOR

Document Type and Number:

WIPO Patent Application WO/2019/156459

Kind Code:

A1

Abstract:

Proposed are a method and a device for transmitting a first PPDU, for supporting a first wireless LAN system, by carrying out beamforming in a wireless LAN system. Specifically, a first STA generates a first PPDU and transmits the first PPDU to a second STA. The first PPDU includes a header field and a first TRN field. The header field includes TRN information indicating that the first TRN field includes a second TRN field for supporting a second wireless LAN system. The second TRN field is configured by reusing a first TRN subfield included in the first TRN field. The first TRN subfield is configured on the basis of a golay sequence for a spatial stream. The first TRN field includes AGC-related information, and the second TRN field does not include the AGC-related information.
