Title:
METHOD AND DEVICE FOR CONFIGURING SPATIAL REUSE FIELD OF TRIGGER FRAME FOR TRIGGERING TB A-PPDU IN WIRELESS LAN SYSTEM
Document Type and Number:
WIPO Patent Application WO/2022/186660
Kind Code:
A1
Abstract:
The present disclosure proposes a method and device for configuring a spatial reuse field in a wireless LAN system. Particularly, a reception STA receives a trigger frame from a transmission STA. The reception STA transmits a TB A-PPDU to the transmission STA through a 320 MHz band. The trigger frame includes a common information field and a special user information field. The common information field includes first to fourth spatial reuse fields. The special user information field includes fifth and sixth spatial reuse fields. The TB A-PPDU includes an HE TB PPDU for a primary 160MHz channel and an EHT TB PPDU for a secondary 160MHz channel.
