Title:
METHOD AND APPARATUS FOR CONFIGURING SPACE REUSE FIELD IN WLAN SYSTEM
Document Type and Number:
WIPO Patent Application WO/2022/158779
Kind Code:
A1
Abstract:
Proposed are a method and an apparatus for configuring a space reuse field in a WLAN system. Specifically, a receiving STA receives a trigger frame from a transmitting STA. The receiving STA transmits a TB PPDU to the transmitting STA through a 320 MHz band. The trigger frame includes first and second non-HT Dup PPDUs. In a first non-HT Dup PPDU, all fields are copied and transmitted for each 20 MHz channel over a first 160 MHz channel having a low frequency within a 320 MHz band. In a second non-HT Dup PPDU, all fields are copied and transmitted for each 20 MHz channel over a second 160 MHz channel having a high frequency within the 320 MHz band. The first non-HT Dup PPDU includes a first common information field and a first special user information field. The second non-HT Dup PPDU includes a second common information field and a second special user information field.
