Abstract: One embodiment of the present specification relates to a method for performing low-latency communications. According to one embodiment, an interframe space (IFS) for low-latency data may be suggested. The interframe space for low-latency data may be set to be greater than PIFS and smaller than DIFS. On the basis of the interframe space for low-latency data, a reception STA may perform EDCA and transmit low-latency data to a transmission STA.

Abstract: In a wireless local area network (WLAN) system, a transmitting multi-link device (MLD) may defer the transmission of a PPDU on a first link, even if a back-off counter of a non-primary link reaches zero, as long as a back-off counter of a primary link does not reach zero. When the transmission of the PPDU is deferred, the back-off counter may be kept at zero.

Abstract: In a wireless local area network system, a station (STA) may transmit a low-latency queue activation signal. The STA may additionally receive, from an access point (AP), allocation of a resource for data transmitted using a low-latency queue. The STA may transmit a signal requesting, from the AP, a change of an allocation resource.

Abstract: In a wireless local area network, a reception station (STA) may receive, from a transmission STA, a first signal via a first link and a second signal via a second link. The reception STA may transmit, to the transmission STA via the second link, a response signal associated with whether the first and second signals are to be received. The response signal may include a first field associated with the feature of the response signal including responses with respect to whether a plurality of signals transmitted via a plurality of links are to be received.

Abstract: An embodiment according to the present specification relates to a method for performing low latency communication. An STA can determine a first parameter set between the first parameter set and a second parameter set on the basis of the time delay value of uplink data. The STA can access a channel on the basis of the first parameter set and transmit the uplink data to an AP.

Abstract: A station (STA) can transmit a first physical protocol data unit (PPDU) including a plurality of first constellation symbols related to initial transmission in a wireless location area network system. The first PPDU includes a first resource unit (RU), and the plurality of first constellation symbols can be assigned to a plurality of subcarriers within the first RU on the basis of a first assignment pattern. The STA can receive a retransmission request related to the first PPDU. The STA can transmit a second PPDU including a plurality of second constellation symbols related to retransmission. The second PPDU includes a second RU, and the plurality of second constellation symbols can be assigned to a plurality of subcarriers within the second RU on the basis of a second assignment pattern.

Abstract: Provided are a method and device for receiving data in a wireless LAN system. Particularly, an STA transmits an operating band negotiation request frame to an AP by means of a first band supported by first and second RFs. The STA receives an operating band negotiation response frame from the AP by means of the first band as a response to the operating band negotiation request frame. The STA changes the first band supported by the second RF into a second band on the basis of the operating band negotiation request frame and the operating band negotiation response frame. The STA receives first data from the AP by means of the first band supported by the first RF and the second band supported by the second RF. The first data is transmitted by means of a multi-band in which the first band and the second band are combined.

Abstract: A method and a device for transmitting data in a wireless LAN system are presented. Particularly, a transmission STA transmits information about a preamble puncturing pattern to a reception STA. The transmission STA transmits data to the reception STA through a 320 MHz band on the basis of the preamble puncturing pattern. The preamble puncturing pattern is determined on the basis of a first bandwidth unit in which a CCA is performed and a second bandwidth unit in which user specific information is repeated. At least one 20 MHz subchannel is punctured in the 320 MHz band on the basis of the preamble puncturing pattern.
