Abstract: The present disclosure is related to a long training field (LTF) sequence for 320 MHz band transmission in a wireless local area network system. The main features comprise the steps of: generating a physical protocol data unit (PPDU); and transmitting the PPDU through a 320 MHz band, wherein the PPDU includes an LTF signal and the LTF signal is generated on the basis of an LTF sequence for the 320 MHz band. Therefore, the proposed LTF has improved effects such as increased bandwidth, an improved PHY layer protocol data unit (PPDU) structure, an improved sequence, and use of a hybrid automatic repeat request (HARQ) technique.

Abstract: Proposed are a method and a device for requesting the same partial information for all transmission STAs within a transmission MLD and responding thereto in a wireless LAN system. Specifically, a reception MLD transmits an ML probe request frame through a first link from the transmission MLD. The reception MLD receives an ML probe response frame through the first link from the transmission MLD. The ML probe request frame includes a first frame body and a probe request ML element. When the first reception ST A requests the same partial information for all transmission STAs, the first frame body includes a first request element and the probe request ML element does not include a profile sub-element of the second transmission STA.

Abstract: Proposed are a method and apparatus for receiving PPDU in a wireless LAN system. Specifically, a receiving STA receives a PPDU from a transmitting STA via broadband and decodes the PPDU. The broadband is a 320 MHz or 160+160 MHz bandwidth that is not preamble punctured. The PPDU includes a first field and a second field. The first field includes L-LTF. The PPDU includes a first signal field and a second signal field. The first field includes L-LTF. The first field is generated on the basis of one of a first, second, third or fourth phase rotation value. The first phase rotation value is a phase rotation value that obtains PAPR of the L-LTE optimized for the broadband on the basis of a first combination of RFs used for transmitting the PPDU. The first combination of RFs is a combination of 160 MHz-capable RFs or 320 MHz-capable RFs.

Abstract: The present disclosure relates to a transmission device and reception device for data in a wireless AV system. The transmission device comprises: a processor for encoding media data thereby generating a compressed bitstream; and a communication unit for: fragmenting the compressed bitstream and mapping the compressed bitstream to an MSDU; generating, for transmission of the MSDU, an MPDU frame sequentially comprising an MAC header, a frame body, and an FCS for the MAC header; generating, for the transmission of the MPDU frame, a PPDU sequentially comprising a preamble, at least one PSDU, and a TRN field; and transmitting the PPDU frame through a radio channel. A radio resource for transmission of actually necessary data can be secured by minimizing unnecessary overhead information (i.e., control-related information in the MAC header) from among data transmitted over radio.

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].
