Abstract
A method and a device for receiving a PPDU in a wireless LAN system are presented. Specifically, a receiving STA receives a PPDU from a transmitting STA through a broadband and decodes the PPDU. The PPDU includes a legacy preamble and first and second signal fields. The legacy preamble and the first and second signal fields are generated on the basis of a first phase rotation value. When the broadband is a 320 MHz band, the first phase rotation value is [1 1 1 −1 1 1 1 −1 −1 −1 −1 1 −1 −1 1 −1].
