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 through a broadband; and
decoding, by the receiving STA, the PPDU,
wherein the PPDU includes a legacy preamble, first and second signal fields,
wherein the legacy preamble and the first and second signal fields are generated based on a first phase rotation value, and
wherein when the broadband is a 320 MHz band, the first phase rotation value is [1 −1 j j 1 1 j −j j −j −1 −1 −j −j 1 −1].
