Abstract: Proposed herein is a method and device for receiving a WUR discovery frame in a wireless LAN system. More specifically, a station (STA) receives a WUR discovery element from an access point (AP). The STA receives the WUR discovery frame from a neighbor AP based on the WUR discovery element. The WUR discovery element includes AP list information. The AP list information includes information on a WUR discovery period. The WUR discovery frame is received during the WUR discovery period.

Abstract: Proposed are a method and device for receiving a feedback frame for MIMO beamforming in a wide band in a wireless LAN system. Specifically, a reception STA receives an NDPA frame from a transmission STA. The reception STA receives an NDP frame from the transmission STA. The reception STA transmits a feedback frame to the transmission STA on the basis of the NDP frame. The feedback frame includes information about a feedback subcarrier for the wide band. When the wide band is a continuous 320 MHz band and the grouping value is Ng, the indexes of the feedback subcarrier are set to [−2036:Ng:−1540], [−1532:Ng:−1036], [−1012:Ng:−516], [−508:Ng:−12], [12:Ng:508], [516:Ng:1012], [1036:Ng:1532] and [1540:Ng:2036].

Abstract: In a wireless local area network (LAN) system, a station (STA) may transmit a first physical protocol data unit (PPDU) including information indicating that a first traffic identifier (TID) is mapped to a first link and a second TID is mapped to a second link. The STA may transmit traffic pertaining to the first TID through only the first link, and traffic pertaining to the second TID through only the second link.

Abstract: One example according to the present specification relates to a method for identifying the format of a PPDU in a wireless LAN (WLAN) system. A receiving STA may receive a first PPDU. The receiving STA may check at least one extra tone of at least one symbol of the first PPDU. The receiving STA may determine, on the basis of the at least one extra tone, the format of the first PPDU as a repeated PPDU format. Thereafter, the receiving STA may receive a second PPDU including the same data as the first PPDU.

Abstract: Proposed are a method and an apparatus for receiving a PPDU over a broadband in a wireless LAN system. Specifically, a receiving STA receives the PPDU from a transmitting STA through a broadband. The receiving STA decodes the PPDU. The broadband is a 320 MHz band or a 160+160 MHz band. The PPDU includes first and second SIG fields. The first SIG field includes information on a broadband bandwidth. The information on the broadband bandwidth consists of 3 bits or 4 bits.

Abstract: In a wireless local area network system, a station (STA) may transmit, to an access point (AP), low-latency queue capability information including information related to whether the STA supports a low-latency queue. The STA may receive, from the AP, low-latency queue operation information including information related to a low-latency queue activation condition. The present invention may include a step of allowing the STA to transmit a low-latency queue activation signal to the AP on the basis of the low-latency queue activation condition.

Abstract: Proposed are a method and an apparatus for receiving a PPDU in a wireless LAN system. Specifically, a reception STA receives a PPDU from a transmission STA through a broadband and decodes the PPDU. The broadband is a 320 MHz band or a 160+160 MHz band. The PPDU includes a first field and a second field. The first field includes an L-STF and an L-LTF. The first field is generated on the basis of a first phase rotation value. The first phase rotation value is generated on the basis of a second phase rotation value and a third phase rotation value. The second phase rotation value is obtained by repeating a phase rotation value for a 160 MHz band, defined in an 802.11ax wireless LAN system.

Abstract: The present invention relates to a device and a method for performing channel selection in a wireless AV system. Such present specification discloses a wireless data transmission device for performing channel selection, the device comprising: a communication unit for performing the steps of selecting an initial channel in a non-connection state on the basis of first channel monitoring, transmitting a periodic beacon onto the initial channel in a standby mode after switching to a connection state, and selecting a new channel in the standby mode on the basis of second channel monitoring in an interval in which beacon transmission does not occur; and a processor connected to the communication unit so as to control the operation of the communication unit. Fast and economic channel selection appropriate for the wireless AV system is possible.

Abstract: Proposed is a method and device for receiving an EHT PPDU on the basis of a tone plan in a wireless LAN system. Specifically, a reception STA receives an EHT PPDU from a transmission STA via a 320 MHz band. The reception STA decodes the EHT PPDU. The EHT PPDU includes a control field and a data field. The control field includes information on a tone plan. The information on the tone plan includes allocation information indicating that a tone plan for the 320 MHz band is configured by four iterations of a tone plan for an 80 MHz band, which is defined in an 802.11ax wireless LAN system. The data field is received via an RU configured based on the allocation information.

Abstract: Proposed are a method and an apparatus for receiving an MU PPDU in a wireless LAN system. Specifically, a receiving STA receives an MU PPDU from a transmitting STA. The receiving STA decodes the MU PPDU. The MU PPDU includes an LSIG field, an RL-SIG field, an HE-SIG field, and an EHT-SIG field. A first reserved bit of the L-SIG field includes information indicating that a first band in which the MU PPDU is transmitted is greater than 160 MHz. A second reserved bit of the HE-SIG field includes information relating to a second band in which the EHT-SIG field is transmitted or the size of the first band. The receiving STA includes an HE STA and an EHT STA.
