Title:
METHOD AND DEVICE FOR TRANSMITTING FEEDBACK FRAME FOR STA OPERATING ONLY IN 20 MHZ IN WIRELESS LAN SYSTEM
Document Type and Number:
WIPO Patent Application WO/2022/220455
Kind Code:
A1
Abstract:
A method and a device for transmitting a feedback frame in a wireless LAN system are proposed. Specifically, a reception STA receives an NDPA frame from a transmission STA through a 320 MHz band. The reception STA receives an NDP frame from the transmission STA. The reception STA transmits a feedback frame to the transmission STA on the basis of the NDPA frame and the NDP frame. The NDPA frame includes information on a partial band. The information on the partial band includes a bitmap configured by one to nine bits. The reception STA is an STA operating only in 20 MHz.
