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: A method and apparatus for communicating in a wireless LAN system are disclosed. The method by which a first station (STA) communicates in a wireless LAN system comprises the steps of: performing, with a second STA, a restricted target wake time (r-TWT) membership setup procedure; and receiving, from the second STA, r-TWT schedule information included in a broadcast TWT element, wherein, on the basis that a specific portion of a first transmission opportunity (TX-OP) in a r-TWT service period (SP) notified by the r-TWT schedule information is not used for downlink (DL) frame transmission corresponding to at least one r-TWT DL traffic identifier (TID) or uplink (UL) frame request corresponding to at least one r-TWT UL TID, the first TXOP may be terminated before the start time of the r-TWT SP.

Abstract: According to the present specification, when a non-AP STA initiates a sensing procedure such as a sensing measurement, an STA, such as an AP, which receives an initiation request of the non-AP STA, may execute a sensing procedure such as a sensing measurement, and transmit the sensing execution result to the non-AP STA.

Abstract: In a wireless local area network (WLAN) system, a transmission station (STA) may transmit a PPDU including a first data field and a second data field to a reception STA, and the second data field may be generated by duplicating the first data field. The PPDU may include information indicating that the first data and the second data are the same data.

Abstract: Proposed are a method and a device for receiving a PPDU in a wireless LAN system. Specifically, a reception STA receives a PPDU from a transmission STA through a broadband and decodes the PPDU. The PPDU includes a legacy preamble, and a first and a second signal field. The legacy preamble and the first and the second signal field are generated on the basis of a first phase rotation value. In a case in which the broadband is a 320 MHz band, the first phase rotation value is [1 1 1 −j j j j 1 j j j 1 −1 −1 −1 j].

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 (LAN) system, a station (STA) may transmit a first physical protocol data unit (PPDU) including information related to low latency traffic. The low latency traffic may be traffic requiring a latency less than or equal to a threshold value. A resource for the low latency traffic may be allocated to the STA. The STA may transmit, via the resource, a second PPDU including the low latency traffic.

Abstract: Proposed are a method and apparatus for receiving a PPDU on which BCC interleaving has been performed in a Multi-RU in a wireless LAN system. Specifically, a reception STA receives, from a transmission STA, a PPDU comprising a data field and decodes the data field. The data field is received via a Multi-RU which is an aggregate of a first RU and a second RU. The data field is generated on the basis of a coded bit string included in a BCC interleaver block. The coded bit string is obtained by interleaving a data bit string on the basis of first and second parameters. The data bit string is interleaved as the data bit string is entered into the BCC interleaver block in rows on the basis of the first parameter and is read out in columns of the BCC interleaver block on the basis of the second parameter.

Abstract: One embodiment according to the present specification relates to a method for constructing a preamble in a wireless LAN (WLAN) system. According to various embodiments, a PPDU may comprise a first signal field and a second signal field. The first signal field may include first information about PHY version. The first information may be determined on the basis of whether the PPDU is an EHT PPDU. The second signal field may include second information about the transmission of the PPDU, which is set on the basis of the first information.

Abstract: An example according to the present specification relates to a technique relating to a configuration of a preamble in a wireless LAN (WLAN) system. A transmitting STA may generate and transmit an EHT PPDU. The EHT PPDU may include an L-SIG field, an RL-SIG field, and a control field. A result of “modulo 3 operation” to a length field value of the L-SIG field may be set to “0”. The RL-SIG field may be configured the same as the L-SIG field. The control field may include 3-bit information relating to a version of a PPDU.
