Abstract: A base station of a wireless communication system is disclosed. The base station of the wireless communication includes a communication module, and a processor. The processor generates a preemption indicator indicating a preempted resource. In this case, the resource indicated by the preemption indicator does not include an orthogonal frequency divisional multiplexing (OFDM) symbol configured as an uplink (UL) symbol by a radio resource control (RRC) signal. The processor is configured to transmit the preemption indicator to a user equipment of the wireless system based on a predetermined period.

Abstract: Disclosed is an access point, which is a registrant desiring to register with a multiple access point network. A wireless communication terminal comprises: a transmitting and receiving unit for transmitting and receiving a wireless signal; and a processor for processing the wireless signal. The processor receives a first device provisioning protocol (DPP) message from a controller of the multiple access point network when the access point is onboarding to the multiple access point network by using a DPP, obtains, from the first DPP message, information on a channel on which the DPP is performed, and transmits a second DPP message to the controller in the channel indicated by the information on the channel.

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.
