Title:
METHOD AND DEVICE FOR TRANSMITTING FEEDBACK FRAME IN WIDE BAND IN WIRELESS LAN SYSTEM
Document Type and Number:
WIPO Patent Application WO/2021/006495
Kind Code:
A1
Abstract:
Proposed are a method and device for receiving a feedback frame for MIMO beamforming in a wide band in a wireless LAN system. Specifically, a reception STA receives an NDPA frame from a transmission STA. 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 NDP frame. The feedback frame includes information about a feedback subcarrier for the wide band. When the wide band is a continuous 320 MHz band and the grouping value is Ng, the indexes of the feedback subcarrier are set to [-2036:Ng:-1540], [-1532:Ng:-1036], [-1012:Ng:-516], [-508:Ng:-12], [12:Ng:508], [516:Ng:1012], [1036:Ng:1532] and [1540:Ng:2036].
