Abstract: According to various embodiments, a multi-link device including a first STA and a second STA may receive a first PPDU by means of the first STA. The PPDU may include information about traffic buffered in the second STA operating in a second link. In response to the first PPDU, the multi-link device may change the second STA from a doze state to an awake state, and transmit information about the state of the second STA by means of the second STA.

Abstract: In a wireless local area network (WLAN) system, an AP multi-link device (MLD) may estimate an uplink transmission time of a non-simultaneous transmit and receive (STR) station (STA) MLD, and on the basis of the time estimation, uplink transmission and downlink transmission in links of the non-STR STA MLD may not overlap.

Abstract: According to various embodiments, a multi-link device operating in a plurality of links can transmit, via a first link, a request frame for changing the first link from among the plurality of links to a second link not included in the plurality of links. The multi-link device can receive a response frame via the first link on the basis of the request frame. The multi-link device can change the first link to the second link on the basis of the response frame.

Abstract: According to various embodiments, a multi-link device including a first STA and a second STA may receive, via the first STA, at least one PPDU within a transmission opportunity (TXOP) configured in a first link. While the at least one PPDU is received, the state of the second STA may be set to a doze state. The multi-link device may receive, via the first STA, a first control frame for the truncation of the TXOP. The multi-link device may change the state of the second STA from the doze state to an awake state on the basis of the first control frame.

Abstract: According to various embodiments, a multi-link device (MLD) including a first STA and a second STA can receive a DL PPDU through a first link. The multi-link device can set the state of the second STA to be a doze state during the duration of the DL PPDU. The multi-link device can transmit an ACK frame through the first link in response to the DL PPDU. The multilink device can set the state of the second STA to be an awake state during the duration of the ACK frame.

Abstract: In a wireless local area network system, a shared AP may receive an announcement frame and a data frame from a sharing AP for multi-AP transmission. In the present disclosure, the announcement frame may be transmitted in a broadcasting scheme. The data field of the announcement frame may include an identifier (ID) of the shared AP. The shared AP may receive a data frame from the sharing AP. In the present disclosure, a receiver address (RA) field of the data frame may include an address of the sharing AP. The shared AP may decode the data frame based on the address of the sharing AP included in the RA field of the data frame.

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 various embodiments, a method performed in a wireless local area network (WLAN) system may comprise the steps of: receiving, by a first station (STA) supporting a first and a second link, a physical protocol data unit (PPDU) generated for a second STA, via the first link, the PPDU being received from a BSS to which the first STA belongs; setting, by the first STA, a first type NAV for the first link on the basis of the PPDU; and setting, by the first STA, a first type NAV for the second link on the basis of the PPDU.
