Title:
METHOD AND DEVICE FOR RECEIVING PPDU THROUGH BROADBAND IN WIRELESS LAN SYSTEM
Document Type and Number:
WIPO Patent Application WO/2021/045421
Kind Code:
A1
Abstract:
Proposed are a method and device for receiving a PPDU in a wireless LAN system. Specifically, a reception STA receives a PPDU from a transmission STA through a broadband and decodes the PPDU. The broadband is a 320 MHz band or a 160+160 MHz band. The PPDU includes a first field and a second field. The first field includes an L-LTF. The first field is generated on the basis of a first or second phase rotation value. The first phase rotation value is generated on the basis of a third phase rotation value and a fourth phase rotation value. The third phase rotation value is a phase rotation value obtained by repeating a phase rotation value for an 80 MHz band defined in an 802.11be wireless LAN system. The fourth phase rotation value is a phase rotation value defined in 80 MHz band units on the basis of an optimal PAPR of the L-LTF.
