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: In a wireless local area network system, a station (STA) may receive, from an access point (AP), a trigger frame including first association identifier (AID) information for orthogonal frequency division multiple access (OFDMA)-based random access and resource allocation information related to a first resource unit corresponding to the first AID information. The first AID information may be related to a first STA group, which has traffic requiring latency equal to or smaller than a first threshold value, among STAs coupled with the AP. The STA may perform OFDMA-based random access on the basis of the first AID information.

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: 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: According to one embodiment of the present specification, an STA may be connected to a primary AP and a secondary AP simultaneously. The STA may acquire control information related to whether the secondary AP can acquire a transmission/reception signal of the primary AP. Thereafter, the STA may transmit a UL signal to the primary AP. The STA may transmit, on the basis of whether the secondary AP can acquire the transmission/reception signal of the primary AP, a block acknowledgement request (BAR) signal for a UL signal to the secondary AP.

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.
