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: 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 system, a multi-link device (MLD) may transmit a multi-link element including a number-of-links field and a link present field indicating whether the number-of-links field exists. The multi-link element further includes a multi-link control field, a common information field, and a link information field. The number-of-links field may be included in the multi-link control field.

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: Provided is a method for providing information related to at least one channel supported in a wireless local area network (WLAN) system. For example, an extreme high throughput (EHT) operation element may include information related to at least one channel in a first band supporting an EHT standard. A very high throughput (VHT) operation element may include information related to at least one channel in a second band supporting a VHT standard. A high throughput (HT) operation element may include information related to at least one channel in a third band supporting an HT standard. The EHT operation element may include information for a channel number related to at least one channel in the first band and information related to a primary channel in the first band.

Abstract: A method for a non-simultaneous transmit and receive (non-STR) device in a wireless local area network (LAN) is provided. The non-STR device may support a multi-link communication related to a first link and a second link. The non-STR device may determine whether to transmit a first physical protocol data unit (PPDU), PPDU, based on a channel access result on the first link and a channel access result on the second link. The non-STR device determines not to transmit the first PPDU through the first link and keeps the back-off counter of the first link at zero (0) when a back-off counter of the first link reaches zero (0) and a back-off counter of the second link does not reach zero (0).

Abstract: The present specification proposes a technical feature related to a wake-up radio (WUR) STA. Specifically, proposed is an operation of updating a parameter related to an operation of a WUR mode. For example, the WUR STA may update a parameter related to the WUR mode by receiving an unsolicited frame from an AP while maintaining the WUR mode. The received frame may have a preset action type.

Abstract: A method and an apparatus for transmitting a PPDU in a WLAN system are proposed. Particularly, a transmission device receives configuration information relating to a multi-band. The transmission device performs channel sensing with respect to the multi-band. The transmission device transmits PPDUs to a reception device via the multi-band on the basis of the result of the channel sensing. In the multi-hand, a first band and a second band are combined. The first band includes a first primary channel. The second band includes a second primary channel. The channel sensing is performed on the basis of a first CW value which is set in common for the first and second bands. If transmission of some PPDUs allocated to the second band of the PPDUs fails, the first CW value is increased.
