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 (WLAN) system, a transmission STA can transmit a PPDU via a 320 MHz channel, and a Medium Access Control (MAC) signal may be generated for the PPDU. The MAC signal may include puncturing pattern information and channel center frequency segment (CCFS) information for a 320 MHz band. The CCFS information may include a first CCFS field related to channel center frequency (CCF) information of a primary 160 MHz channel, and a second CCFS field related to CCF information of a 320 MHz channel.

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.

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: One embodiment according to the present specification relates to a technique for multiple frame transmission in a wireless LAN (WLAN) system. A transmission STA can transmit a first next generation V2X physical protocol data unit (NGV PPDU) from among a plurality of NGV PPDUs for a multiple frame transmission mode. Afterwards, the transmission STA can identify a channel state for the transmission of a second NGV PPDU from among the plurality of NGV PPDUs. The transmission STA can determine, on the basis of the channel state, whether to transmit the second NGV PPDU.

Abstract: Proposed are a method and a device for transmitting an NGV frame in a wireless LAN system. Specifically, a transmission device generates an NGV frame and transmits same via a first band. The NGV frame includes an L-STF, L-LTF, L-SIG, RL-SIG, NGV-SIG, NGV-STF, NGV-LTF and NGV-Data. The NGV-Data includes at least one midamble. The at least one midamble is generated on the basis of a sequence of the NGV-LTF. The sequence of the NGV-LTF includes two time sequences which, in a frequency domain, are mapped to a tone including two tone units, and in a time domain, are repeated in a single OFDM symbol. The at least one midamble includes one or two OFDM symbols.

Abstract: One example according to the present specification relates to a technique for forming a midamble in a wireless LAN (WLAN) system. A reception STA may receive an NGV PPDU. The NGV PPDU may include a preamble, a data field, and a midamble. The midamble format may be determined as either a first format or a second format. A midamble symbol of the first format may include an LTF signal and a GI pertaining to the LTF signal.

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: The present specification proposes various technical features applicable to WLAN sensing. For example, the present specification proposes a procedure for grouping wireless devices performing WLAN sensing. Wireless devices performing WLAN sensing may be grouped based on a channel and/or the type and properties of a wireless device. Further, the present specification proposes a signal transmission/reception procedure for grouped wireless devices to perform WLAN sensing. Specifically, the present specification proposes a WLAN sensing-related signal transmission/reception operation method in view of a channel and/or the type and properties of a wireless device.
