Title:
METHOD AND APPARATUS FOR INDICATING BANDWIDTH OF NON-HT DUP PPDU BEING TRANSMITTED IN 320 MHZ BAND IN WIRELESS LAN SYSTEM
Document Type and Number:
WIPO Patent Application WO/2022/158780
Kind Code:
A1
Abstract:
Proposed are a method and apparatus for indicating a transmission band for a non-HT Dup PPDU in a wireless LAN system. Particularly, a reception STA receives a non-HT Dup PPDU from a transmission STA via a preset frequency band. The reception STA decodes the non-HT Dup PPDU. All fields of the non-HT Dup PPDU are duplicated and transmitted on every 20 MHz channel in the preset frequency band. The non-HT Dup PPDU includes a service field within a data field. The service field comprises first to sixteenth bits. The preset frequency band is configured on the basis of the sixth to eighth bits. If the preset frequency band is a 320 MHz band, the sixth bit is set to 1, the seventh bit is set to 1, and the eighth bit is set to 1.
