1. A method in a wireless local area network (WLAN) system, the method comprising:
receiving, by a receiving station (STA), a Physical Protocol Data Unit (PPDU) from a transmitting STA; and
decoding, by the receiving STA, the PPDU,
wherein the PPDU includes a legacy preamble, first and second signal fields,
wherein a first phase rotation value is applied to the legacy preamble and the first and second signal fields 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].
