Abstract
The present invention relates to a method for transmitting and receiving a Physical Protocol Data Unit (PPDU) and an apparatus for supporting the same. Particularly, a method for transmitting a Physical Protocol Data Unit (PPDU) performed by an apparatus in a wireless communication system may include generating a High Efficiency-Short Training Field (HE-STF) sequence in a frequency domain throughout a transmission bandwidth of the PPDU and transmitting the PPDU that includes an HE-STF field which is constructed based on the HE-STF sequence, wherein the HE-STF sequence may be mapped to a data tone except a direct current tone and a guard tone, and wherein a non-zero value may be mapped to all data tones that include a tone index which is a multiple of a predetermined value in the data tone.
