Abstract: Disclosed is a method for a station (STA) to transmit a frame in a wireless communication system. In the present invention, the STA receives a management frame including a first operation element and a second operation element from an access point (AP), and transmits a PPDU to the AP on the basis of the first operation element or the second operation element. Here, the first operation element may indicate a basic service set (BSS) operation channel for a legacy STA, and the second operation element may indicate a BSS operation channel for the STA that is not the legacy STA.
