Abstract: Disclosed are a method and an apparatus for generating an STF signal usable in a wireless LAN system. The STF signal is included in a field used to improve AGC estimation of a MIMO transmission. A portion of the STF signal is used to transmit an uplink, and can be used for uplink MU PPDUs transmitted from a plurality of STAs. The STF that is suggested, for example, is used for a 40 MHz band or an 80 MHz band and can be generated based on a sequence in which a predetermined M sequence is repeated. The predetermined M sequence can be a binary sequence of which the length is 15 bits.

Abstract: Provided are a method and a device for transmitting a feedback frame in a wireless LAN system. Particularly, a first wireless station receives, from a second wireless station, a feedback request field including an LTF. The first wireless station configures feedback information on a wireless channel corresponding to a preset frequency band by using the feedback request field. The first wireless station transmits the feedback information to the second wireless station.

Abstract: Proposed is a control field including allocation information regarding a resource unit (RU) in a wireless local area network (WLAN) system supporting a plurality of RUs. A data field may be transmitted in unit of the RU. For a case where two 106-RUs are arranged and a plurality of user stations (STAs) are multiplexed to the respective 106-RUs, a SIG-B field may be used to perform signaling. More specifically, the number of STAs to be multiplexed may be indicated by using first and second identification bits in a user-common field of the SIG-B field.

Abstract: A beamforming training using a polarization in a wireless local area network is provided. An initiator receives a response frame from the responder. The response frame includes information about a polarization type selected by the responder. The initiator transmits a sector sweep message to the responder using the selected polarization type through all sectors during a sector sweep.

Abstract: A method for the multiple beamforming training and an apparatus using the same are provided. An initiator determines a candidate sector to be used for a transmission during a sector sweep. After the initiator exchanges with a responder an information request frame and an information response frame about the multiple beamforming training through the candidate sector, the responder performs a plurality of beam refinement protocol (BRP) processes using a plurality of polarized channels through the candidate sector.

Abstract: Proposed are 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 the EHT PPDU from a transmission STA through 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 about a pilot tone. The information about the pilot tone includes allocation information indicating that a first pilot tone for the 320 MHz band is configured by repeating a second pilot tone for an 80 MHz band defined in an 802.11ax wireless LAN system. The first pilot tone is received in a data field on the basis of the allocation information.
