Abstract: A multi-link device using a plurality of links is disclosed. The multi-link device comprises: a transceiving unit; and a processor. When the multi-link device transmits a plurality of PPDUs simultaneously on the plurality of links using the transceiving unit, the processor determines a transmission end time of the plurality of PPDUs on the basis of whether the multi-link device transmits a frame requesting an ACK.

Abstract: Disclosed is a method for transmitting or receiving a TB PPDU based on a trigger frame in a wireless communication system. A terminal receives a trigger frame from an access point (AP) and transmits a response frame in response to the trigger frame. The response frame may be generated on the basis of information obtained from a first plurality of spatial reuse fields or a second plurality of spatial reuse fields of the trigger frame according to a resource unit and/or a format of the response frame.

Abstract: Disclosed is a station which communicates with an access point (AP) multi-link device using a plurality of links. The AP multi-link device comprises: a transceiver, and a processor. The processor receives, by using the transceiver, a management frame from the AP multi-link device, and obtains, from the management frame, a multi-link setup element including information required for setting the plurality of links. The multi-link setup element includes a common part including information corresponding to all links signaled by the multi-link setup element, and link-specific parts independently including information corresponding to each of the plurality of links signaled by the multi-link setup element.

Abstract: Disclosed is a method for transmitting and receiving a physical protocol data unit (PPDU) in a wireless communication system. A terminal receives a preamble of the PPDU from an access point (AP). The preamble includes a universal signal (U-SIG) field and an extremely high throughput (EHT)-SIG field, wherein the EHT-SIG field may be configured with at least one content channel on a frequency axis. Here, the number of the at least one content channel may be recognized on the basis of the U-SIG field. Subsequently, the terminal receives data of the PPDU on the basis of the U-SIG field and the EHT-SIG field.
