Title:
METHOD AND APPARATUS FOR TRANSMITTING EHT PPDU IN WIRELESS LAN SYSTEM
Document Type and Number:
WIPO Patent Application WO/2020/122523
Kind Code:
A1
Abstract:
A method and apparatus for transmitting an EHT PPDU in a wireless LAN system is proposed. Specifically, a transmitting STA generates an EHT PPDU including a STF signal. The transmitting STA transmits the EHT PPDU to a receiving STA. The STF signal is generated on the basis of an EHT STF sequence for a 320 MHz band or a 160 + 160 MHz band. The EHT STF sequence for the 320 MHz band is a first sequence in which a predetermined M sequence is repeated, which is defined as {M 1 M 1 M 1 -M 0 M 1 -M 1 -M 1 M 0 M 1 M 1 M 1 -M 0 -M -1 M -1 M -1 -M}*(1+j)/sqrt(2). The sqrt() represents the square root. The predetermined M sequence is defined as M = {-1, -1, -1, 1, 1, 1, -1, 1, 1, 1, -1, 1, 1, -1, 1}.
