METHOD AND APPARATUS FOR RECEIVING EHT PPDU IN WIRELESS LAN SYSTEM

WIPO Patent Application WO/2020/171462

A1

Proposed are a method and an apparatus for receiving an EHT PPDU in a wireless LAN system. Specifically, a reception STA receives an EHT PPDU including an STF signal from a transmission STA through a 320 MHz band or a 160+160 MHz band. The reception STA decodes the EHT PPDU. The STF signal is generated on the basis of an EHT STF sequence for the 320 MHz band or the 160+160 MHz band. The EHT STF sequence for the 320 MHz band is a first sequence in which a preconfigured M sequence is repeated, and is defined as {M -1 M 0 -M -1 M 0 M -1 M 0 -M -1 M 0 M -1 M 0 M -1 -M 0 -M 1 -M 0 -M -1 M}*(1+j)/sqrt(2).
