Title:
METHOD AND DEVICE FOR GENERATING STF SIGNAL BY USING NBT METHOD IN WIRELESS LAN SYSTEM
Document Type and Number:
WIPO Patent Application WO/2019/132391
Kind Code:
A1
Abstract:
Suggested are a method and a device for transmitting a PPDU by using an NBT method in a wireless LAN system. A transmitting device generates an STF field, and transmits a PPDU including the STF field to a receiving device via the 1 MHz band. The STF field includes an NB-STF sequence. The STF field is generated by applying 64 IFFT with respect to the 1 MHz band, and the tone spacing of the STF field is 15.625 KHz. A first tone index for which a coefficient is configured from the NB-STF sequence is configured based on the tone spacing of the STF field. The coefficient in the NB-STF sequence is configured for a tone indicated by the first tone index, on the basis of a coefficient in an L-STF sequence.
