Title:
METHOD AND DEVICE FOR TRANSMITTING EHT PPDU IN WIRELESS LAN SYSTEM
Document Type and Number:
WIPO Patent Application WO/2020/111638
Kind Code:
A1
Abstract:
A method and device for transmitting an EHT PPDU in a wireless LAN system is proposed. Specifically, a transmission STA generates an STF signal for a 320 MHz band. The transmission STA transmits an EHT PPDU including the STF signal to a reception STA. The STF signal is generated on the basis of an EHT STF sequence. The EHT STF sequence is a first sequence in which preconfigured sequence M 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). Sqrt() represents a square root. Preconfigured sequence M is defined as M = {-1, -1, -1, 1, 1, 1, -1, 1, 1, 1, -1, 1, 1, -1, 1}.
