1. A method for transmitting a Physical Protocol Data Unit (PPDU) in a wireless LAN system, the method comprising:
generating, by a transmitting device, the PPDU, wherein the PPDU includes a legacy preamble and a data field; and
transmitting, by the transmitting device, the PPDU to a receiving device,
wherein the legacy preamble includes a Legacy-Short Training Field (L-STF) and a Legacy-Long Training Field (L-LTF),
wherein the legacy preamble is generated by applying a first phase rotation value for a 320 MHz band, and
wherein the first phase rotation value is given as follows based on a subcarrier index k:
