Abstract: In a wireless local area network (LAN) system, a transmission station (STA) may transmit, to a receiving STA, a PHY protocol data unit (PPDU) including a first redundancy version of transmission data. On the basis of whether an acknowledgement (ACK) or negative ACK (NACK) frame is received within a threshold time, the transmission STA may determine a second redundancy version of the transmission data to be retransmitted.

Abstract: In a wireless local area network (LAN) system, a station (STA) may transmit a first physical protocol data unit (PPDU) including information indicating that a first traffic identifier (TID) is mapped to a first link and a second TID is mapped to a second link. The STA may transmit traffic pertaining to the first TID through only the first link, and traffic pertaining to the second TID through only the second link.

Abstract: According to one embodiment of the present specification, an STA may be connected to a primary AP and a secondary AP simultaneously. The STA may acquire control information related to whether the secondary AP can acquire a transmission/reception signal of the primary AP. Thereafter, the STA may transmit a UL signal to the primary AP. The STA may transmit, on the basis of whether the secondary AP can acquire the transmission/reception signal of the primary AP, a block acknowledgement request (BAR) signal for a UL signal to the secondary AP.

Abstract: A method performed by a first STA in a wireless local area network (WLAN) according to various embodiments may comprise transmitting or receiving a TWT setup request message and a TWT setup response message. The first STA may perform a TWT operation on the basis of the TWT setup request message and the TWT setup response message. The TWT setup request message and the TWT setup response message may be transmitted or received through a first link included in multiple links. The first STA may set the first link to be in an awake state in order to perform the TWT operation through the first link.

Abstract: In a wireless local area network (WLAN) system, a transmission STA can transmit a PPDU via a 320 MHz channel, and a Medium Access Control (MAC) signal may be generated for the PPDU. The MAC signal may include puncturing pattern information and channel center frequency segment (CCFS) information for a 320 MHz band. The CCFS information may include a first CCFS field related to channel center frequency (CCF) information of a primary 160 MHz channel, and a second CCFS field related to CCF information of a 320 MHz channel.

Abstract: According to various embodiments, a multi-link device (MLD) operating in a plurality of links including a first link can transmit a request frame to a first AP of an AP MILD through a first STA (station), wherein the request frame includes an information field for requesting every element included in an element set designated for a second link. The MILD can, on the basis of the request frame, receive every element included in the element set designated for the second link.

Abstract: In a wireless local area network (LAN) system, a first station (STA) may check the transfer failure of a first acknowledgement (ACK) signal for a first frame, the signal being received through a first link. The first STA may transmit report information related to the transfer failure of the first ACK signal to a second STA through a second link. Here, the report information may include identification information associated with the first link. The first STA may receive a second frame from the second STA through the first link. The first STA may transmit a second ACK signal for the second frame to the second STA through the first link on a narrowband.

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.
