Claim 0:
1. A method for transmitting a physical protocol data unit (PPDU) in a WLAN system, the method comprising:
generating the PPDU by a transmitting device, the PPDU including 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 [1 −1 −1 −1 1 −1 −1 −1 −1 1 1 1 −1 1 1 1].
