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 (WLAN) system, a transmission station (STA) may transmit a PPDU including a first data field and a second data field to a reception STA, and the second data field may be generated by duplicating the first data field. The PPDU may include information indicating that the first data and the second data are the same data.

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: The present specification proposes a method for configuring a trigger frame that can be applied to a next-generation Wireless LAN (WLAN) system and an apparatus using the method. As an example, the trigger frame of the present specification may set a bandwidth for a trigger-based (TB) PPDU of up to 320 MHz. As another example, the trigger frame of the present specification may set the format of the TB PPDU transmitted through a primary bandwidth. As another example, the trigger frame of the present specification may trigger an aggregated PPDU (A-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: In a wireless local area network (LAN) system, a sharing access point (AP) can determine a Q-matrix related to a first antenna of a first shared AP, a second antenna of the first shared AP, a third antenna of a second shared AP, and a fourth antenna of the second shared AP. The sharing AP can transmit, to the first shared AP, a first value related to the first antenna and a second value related to the second antenna in the Q-matrix. The sharing AP can transmit, to the second shared AP, a third value related to the third antenna and a fourth value related to the fourth antenna in the Q-matrix.
