Title:
METHOD AND DEVICE FOR CONFIGURING SPECIAL USER INFORMATION FIELD IN TRIGGER FRAME EVEN WHEN TRIGGERING ONLY HE TB PPDU IN WIRELESS LAN SYSTEM
Document Type and Number:
WIPO Patent Application WO/2022/203269
Kind Code:
A1
Abstract:
The present specification presents a method and device for configuring a special user information field in a trigger frame even when triggering only an HE TB PPDU in a wireless LAN system. Specifically, a reception STA receives a trigger frame from a transmission STA. The reception STA transmits an HE TB PPDU to the transmission STA. A special user information field comprises a PHY version ID subfield, a second bandwidth field, fifth and sixth spatial reuse fields, a U-SIG disregard and validate subfield, and a reserved subfield. A first bandwidth field comprises information about a bandwidth at which the HE TB PPDU is transmitted. If the bandwidth at which the HE TB PPDU is transmitted is 20 MHZ, then the fifth and sixth spatial reuse fields are set to the value of a first spatial reuse field.
