    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: In a wireless local area network (WLAN) system, a first station (STA) may transmit first information related to a maximum value of a hybrid automatic repeat request (HARQ) index supported by the first STA, and second information related to a time limit related to the HARQ index. The HARQ index may be used for an HARQ operation of the first STA, and the time limit may be used for a maximum storage time of an HARQ buffer related to the HARQ index. The first STA may perform an association with a second STA on the basis of the first information and the second information.

    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: The present document relates to a method and device for an Access Point (AP) to transmit ACK/NACK signals for MU (Multi-User) transmission data of a plurality of stations (STA) in a wireless LAN (WLAN) system. To this end, the method and device are characterized in that a STA responds to a trigger frame received from an AP, transmits data to the AP through an MU access technique, and sets an ACK policy value for data transmitted on the basis of the trigger frame to another value other than a first ACK policy value requesting an ACK signal transmission on the basis of a block ACK request.

    Abstract: A method for an STA to transmit or receive a frame in a WLAN, according to one embodiment of the present invention, comprises the steps of: receiving a first HARQ trigger frame that triggers transmission of an A-PHDU into which PHDUs that are PHY data transmission units for a HARQ process are combined; transmitting at least one PHDU within the A-PHDU on the basis of the first HARQ trigger frame at the timing designated for the STA; and retransmitting the at least one PHDU or transmitting a new PHDU according to reception of a second HARQ trigger frame, wherein the first HARQ trigger frame includes timing offset information between the STA and another STA transmitting the PHDU within the A-PHDU, and the STA may determine the timing designated for the STA by using the timing offset information.

    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.

    Abstract: A method for receiving a frame by a station (STA) in a wireless LAN (WLAN) according to the present embodiment: performing a wake-up radio (WUR) negotiation procedure for exchanging WUR operation parameters with an access point (AP) through a primary connectivity radio (PCR); entering a WUR mode; and waking up when a WUR frame is received through a WUR and monitoring a beacon frame through the PCR from the next beacon transmission timing, the WUR operation parameters exchanged through the WUR negotiation procedure include first time information indicating a time for which the STA that has woke up upon reception of the WUR frame needs to monitor the beacon frame from the next beacon transmission timing, and the STA can return to the WUR mode when the beacon frame is not received until the time indicated by the first time information has elapsed.
