Abstract: According to various embodiments, a multi-link device (MLD) operating in a plurality of links may transmit a first request frame for requesting information on the plurality of links. The multi-link device may receive a first response frame on the basis of the first request frame. The first response frame may include information on a ratio of stations (STAs) using a first link as an anchor link, and information on a ratio of STAs using a second link as an anchor link.

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: Provided is a method and device for transceiving a frame in a wireless Local Area Network (LAN) system. Particularly, an Access Point (AP) transmits a first frame to a first station (STA) via a first band. The AP receives a second frame from a second STA via a second band while the first frame is being transmitted. The first band and the second band are combined with each other as a multi-band. The multi-band simultaneously supports a Downlink (DL) transmission and a Uplink (UL) transmission. The relationship between the first STA and the second STA is a hidden node. A Physical (PHY) header of the first frame includes channel status information of the second band. A Network Allocation Vector (NAV) of the first STA is set up on the basis of the channel status information.

Abstract: In a wireless local area network system, a sharing access point (AP) may determine a long training field (LTF) subcarrier pattern for each of multiple streams, wherein an LTF symbol is used for at least one stream among a first to a third stream, the number of the LTF symbols is determined on the basis of the number of antennas of a shared AP having the maximum number of antennas among multiple shared APs associated with the sharing AP, and the first to the third stream are assigned different subcarrier patterns. The sharing AP may transmit information associated with the LTF subcarrier pattern.

Abstract: Proposed are a method and a device for transmitting data in a wireless LAN system. Specifically, a transmission device receives configuration information of a multi-band formed by aggregating first to third bands. The transmission device carries out channel sensing on the first to third bands. The transmission device transmits data to a receiving device on the basis of the result of the channel sensing. The first band comprises a first primary channel and a first secondary channel; the second band comprises a second primary channel and a second secondary channel; and the third band comprises a third primary channel and a third secondary channel.

Abstract: A method for an STA for receiving a WUR frame in a WLAN, according to one embodiment of the present invention, comprises the steps of: receiving a WUR frame including a first portion of a TSF timer and an MIC value; calculating an MIC verification value on the basis of the first portion of the TSF timer and the TSF timer stored in the STA; and determining whether to discard the received WUR frame depending on whether the MIC value included in the WUR frame matches the calculated MIC verification value, wherein the first portion of the TSF timer included in the WUR frame is the 8-bits following the least significant N-bit in the TSF timer, and the STA may obtain a continuous 48-bit partial TSF timer value through the first portion of the TSF timer and a second portion of the TSF timer stored in the STA, and may calculate the MIC verification value on the basis of the obtained 48-bit partial TSF timer value.

Abstract: In a wireless local area network (WLAN) system, a transmitting multi-link device (MLD) may defer the transmission of a PPDU on a first link, even if a back-off counter of a non-primary link reaches zero, as long as a back-off counter of a primary link does not reach zero. When the transmission of the PPDU is deferred, the back-off counter may be kept at zero.

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.
