METHOD FOR TRANSMITTING DATA AND DEVICE USING SAME

摘要

Provided are a method for transmitting data and a device using the same in a wireless LAN. A transmitter transmits a physical layer protocol data unit (PPDU) in a transmission bandwidth. The PPDU includes a first part to which a first fast Fourier transform (FFT) size is applied, and a second part to which a second FFT size is applied. The number of pilots of the second part is identical to the number of pilots of the first part, and the pilot frequency location of the second part is identical to the pilot frequency location of the first part.
