    Abstract: A method for transmitting or receiving a frame by a STA in a WLAN according to one embodiment of the present invention may comprise the steps of: receiving a first frame including a PHY header and an A-PHDU obtained by aggregating PHDUs which are PHY data transmission units for a HARQ process; decoding at least one PHDU for the STA in the A-PHDU on the basis of the PHY header; and transmitting a second frame including ACK/NACK information on each of the at least one PHDU for the STA, according to a decoding result, wherein a CRC is individually provided to each of the PHDUs included in the A-PHDU, and the STA transmits a NACK through the second frame in relation to a particular PHDU for which a CRC failure has occurred during the decoding of the particular PHDU.

    Abstract: A method and an apparatus for transmitting a PPDU in a WLAN system are proposed. 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 PPDUs to a reception device via the multi-band on the basis of the result of the channel sensing. In the multi-hand, a first band and a second band are combined. The first band includes a first primary channel. The second band includes a second primary channel. The channel sensing is performed on the basis of a first CW value which is set in common for the first and second bands. If transmission of some PPDUs allocated to the second band of the PPDUs fails, the first CW value is increased.

    Abstract: In a wireless local area network (LAN) system, a station (STA) may transmit a first physical protocol data unit (PPDU) including information related to low latency traffic. The low latency traffic may be traffic requiring a latency less than or equal to a threshold value. A resource for the low latency traffic may be allocated to the STA. The STA may transmit, via the resource, a second PPDU including the low latency traffic.

    Abstract: Proposed are a method and device for performing UL transmission through a multi-link in a wireless LAN system. In detail, a transmission STA generates a first frame including BQR information regarding the multi-link. The transmission STA transmits the first frame to a reception STA. The multi-link is a link in which first and second links are combined with each other. The BQR information regarding the multi-link includes channel state information regarding at least one of the first and second links. The first frame is transmitted through the second link.

    Abstract: A receiving STA can receive a first PPDU including a first data block and a second data block in a wireless local area network system according to various embodiments. The first data block and the second data block can be configured by a first index. Afterward, the receiving STA can transmit a retransmission request signal for the first data block. The receiving STA can receive the first data block again. Then, the receiving STA can combine the first and second data blocks configured by the first index.

    Abstract: In a wireless local area network (LAN) system, a transmitting STA can encode at least one codeword on the basis of a plurality of data blocks. The transmitting STA can encode a second codeword on the basis of a first data block and a second data block that is continuous with the first data block, in response to a first data block transmission request signal from among the plurality of data blocks. The transmitting STA can transmit the encoded second codeword to a receiving STA.

    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.
