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.

Abstract: A method and device for transmitting data in a wireless LAN system are provided. Particularly, a transmission device receives configuration information relating to a multi-band. The transmission device performs channel sensing with respect to the multi-band. The transmission device transmits data to a reception device via the multi-band on the basis of the result of the channel sensing. A first band and a second band are combined in the multi-band. The first band comprises a first primary channel, and the second band comprises a second primary channel. The result of the channel sensing is obtained on the basis of whether or not the first primary channel is idle until a first BC value becomes 0 and whether or not the second primary channel is idle until a second BC value becomes 0. The first BC value is selected within a first CW configured with respect to the first primary channel. The second BC value is selected within a second CW configured with respect to the second primary channel.
