Abstract: The present disclosure proposes a transmitting multi-link device (MLD) including a first station (STA) operating on a first link and a second STA operating on a second link. The transmitting MLD acquires a first transmission opportunity (TXOP) in the first link and transmits a first physical protocol data unit (PPDU) in the first link. The transmitting MLD receives a block acknowledgment (BA) frame for the first PPDU in the first link and transmits a second PPDU in the first link. The transmitting MLD changes a responder of the first TXOP based on not receiving, from the receiving MLD, a BA frame for the second PPDU within a preconfigured time interval in the first link.

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.

IPC: H04W74/08

Abstract: In a wireless local area network (WLAN) system, an STA performs CCA on resources allocated thereto via a trigger frame from an AP and can transmit a TB PPDU via an idle channel among the allocated resources on the basis of the result of the CCA, wherein the PHY of the TB PPDU may include information about the result of the CCA.

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: A transmitting multi-link device (MLD) in a wireless local area network system enables a first station (STA) to perform a back-off operation again without transmitting PPDU, if a second STA is in the middle of receiving even when a back-off counter (BC) of the first STA becomes 0. The first STA and the second STA are included in the same transmitting MLD. The first STA operates on a first link and the second STA operates on a second link. The first and second links are included in a non-simultaneous transmit and receive (NSTR) link pair.

Abstract: In a wireless local area network (LAN) system, a transmitting device can delay PPDU transmission in a first link when a backoff counter of a second link does not reach 0 even if a backoff counter of the first link reaches 0.
