Title:
METHOD AND APPARATUS FOR RECEIVING PPDU THROUGH BROADBAND IN WIRELESS LAN SYSTEM
Document Type and Number:
WIPO Patent Application WO/2021/029552
Kind Code:
A1
Abstract:
Proposed are a method and an apparatus 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-STF and an L-LTF. The first field is generated on the basis of a first phase rotation value. The first phase rotation value is generated on the basis of a second phase rotation value and a third phase rotation value. The second phase rotation value is obtained by repeating a phase rotation value for a 160 MHz band, defined in an 802.11ax wireless LAN system. The third phase rotation value is defined in units of 80 MHz bands on the basis of the optimal PAPRs of the L-STF and L-LTF.
