    Abstract: In a wireless local area network system, a reception multi-link device (MLD) may not transmit a CTS frame, even if the reception multi-link device receives an RTS frame via a second link, in the case that an STA operating via a first link is a TXOP responder. In detail, the reception MLD may include at least one non-simultaneous transmit and receive (NSTR) link pair. A first STA affiliated with the MLD may determine to respond with the CTS frame to the RTS frame. The first STA does not respond with the CTS frame based on another STA being a transmission opportunity (TXOP) responder on another link.

    Abstract: Proposed are a method and device for acquiring information on links between MLDs in a wireless LAN system. Specifically, a receiving MLD transmits a probe request frame to a transmitting MLD through a first link. The receiving MLD receives a probe response frame from the transmitting MLD through the first link. The transmitting MLD comprises: a first transmitting STA operating in the first link; a second transmitting STA operating in a second link; and a third transmitting STA operating in a third link. The receiving MLD comprises a first receiving STA operating in the first link. When the first receiving STA requests for information on the second and third links, the probe request frame includes link identifiers for the second and third links. When the first receiving STA requests for information on all the links, the probe request frame does not include link identifiers for all the links.

    Abstract: A method and an apparatus for transmitting a PPDU on the basis of an S-TDMA in a wireless LAN system are presented. Particularly, an AP transmits a trigger frame to a first STA and a second STA. The AP receives, on the basis of the trigger frame, a first trigger-based frame from the first STA and a second trigger-based frame from the second STA. The trigger frame includes a common information field and a user information field. The common information field includes S-TDMA indication information enabling the S-TDMA to be performed. The user information field includes: allocation information on a first RU to which the first trigger-based frame and the second trigger-based frame are transmitted; first symbol offset information on the first trigger-based frame; and second symbol offset information on the second trigger-based frame.

    Abstract: The present specification proposes a method for resuming a PHY-level HARQ operation in a wireless local area network (WLAN) system. The method may include transmitting a resume signal including information related to resumption of hybrid automatic repeat request (HARQ) retransmission. The method may include transmitting a physical protocol data unit (PPDU) after transmitting the resume signal. The PPDU and the resume signal may be transmitted in different transmission opportunities (TXOPs).

    Abstract: A method for supporting dual connectivity performed by a STA connected to a first AP and a second AP in a WLAN according to one embodiment includes: determining whether a predetermined AP change condition is satisfied while performing uplink transmission based on a first operating band for the first AP; transmitting an AP change request frame to the first AP in order to perform uplink transmission based on a second operating band for the second AP when it is determined that the AP change condition is satisfied; receiving an AP change response frame from the first AP in response to the AP change request frame; performing a channel switch operation from the first operating band to the second operating band when the AP change request frame is received; and transmitting an uplink frame to the second AP based on the second operating band.
