Abstract
Provided are method for transmitting a data block in a wireless LAN and an apparatus using the same. 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 second FFT size increases by integer times as the size of the transmission bandwidth increases.
