Abstract: The present invention relates to a data transmission device and reception device in a wireless AV system. Disclosed in the present specification is a wireless data transmission device comprising: a processor for generating a compressed bitstream by encoding media data; and a communication unit for segmenting the compressed bitstream, mapping the segmentation results to MSDUs, generating an MPDU frame sequentially including a MAC header, a frame body, and an FCS associated with the MAC header in order to transmit the MSDUs, generating a PPDU frame sequentially, which includes a preamble to which at least a portion of the MAC header is mapped, at least one PPDU to which the frame body and the FCS are mapped, and a TRN field, and transmitting the PPDU frame through a wireless channel. A data transmission rate can be improved through a reduction in overhead information.

Abstract: Provided are a method and apparatus for receiving only complete information on other access points (APs) in a transmitting multi-link device (MLD) in a wireless local area network (WLAN) system. Specifically, a receiving MLD transmits a probe request frame to the transmitting MLD through a first link. The receiving MLD receives a probe response frame from the transmitting MLD through the first link. The probe request frame includes a frame body and a profile field of a second receiving station (STA). When a first receiving STA does not request complete information on the first link and requests complete information on the second link, the complete information on the second link is requested based on the profile field of the second receiving STA. The probe response frame does not include the complete information on the first link, and includes only the complete information on the second link.

Abstract: The present specification provides a technical feature for extended range transmission in a wireless LAN signal. A physical protocol data unit (PPDU) of the present specification may include a universal signal (U-SIG) field. The U-SIG field may be received through first to the fourth symbols, the second symbol may include information in which bit information of the first symbol is repeated, and the fourth symbol may include information in which bit information of the third symbol is repeated. The receiving STA of the present specification may determine the transmission mode of the PPDU based on constellation mapping pattern of the first and second symbols.

Abstract: Proposed herein is a method and device for setting limited RUs and MRUs in a WLAN system. More specifically, a receiving STA receives a PPDU from a transmitting STA through a preset frequency band, and decodes the PPDU. The receiving STA is an STA operating only in a 20MHz band. The PPDU includes a preamble and a data field. The data field is received through resources other than the first RU and the first MRU among the preset frequency band.

Abstract: A method performed in a wireless local area network (LAN) system is presented. Particularly, a first type access point (AP) #1 can receive a trigger frame from a second type AP. The first type AP #1 can transmit a null data packet (NDP) request frame to a first station (STA). The first type AP #1 can receive a first NDP frame from the first STA, and receive a second NDP frame from a second STA. The first type AP #1 can receive a feedback request frame from the second type AP. The first type AP #1 can transmit an NDP feedback frame to the second type AP on the basis of the first and second NDP frames.

Abstract: A method and device for transmitting an NGV frame in a wireless LAN system is proposed. Specifically, a transmission device generates an NGV frame and transmits the NGV frame through a first band. The NGV frame includes an L-STF, an L-LTF, an L-SIG, an NGV-SIG, an NGV-STF, an NGV-LTF, and NGV-Data. The L-STF, the L-LTF, the L-SIG, and the NGV-SIG are duplicated in units of second bands and transmitted through the first band. The NGV-STF, the NGV-LTF, and the NGV-Data are transmitted through a full band of the first band. The first band is a 20 MHz band, and a second band is a 10 MHz band.

Abstract: A method and an apparatus for transmitting an EHT PPDU in a WLAN system are proposed. Specifically, a transmitter generates an EHT PPDU and transmits, on the basis of an RF, the EHT PPDU to a receiver through a 320 MHz band in which an 80 MHz band is punctured. A legacy preamble includes an L-STF and an L-LTF. The legacy preamble is generated by applying a first phase rotation value. The first phase rotation value is determined on the basis of a first scheme and a second scheme. The first scheme is a scheme of obtaining an optimal PAPR in the L-STF and the L-LTF. The second scheme is a scheme of obtaining an optimal PAPR on the basis of the maximum transmission bandwidth supported by the RF. The first phase rotation value is obtained on the basis of a second phase rotation value and a third phase rotation value. The second phase rotation value is a phase rotation value that repeats a phase rotation value defined for the 80 MHz band in an 802.11ax system. The third phase rotation value is a phase rotation value defined in units of the 80 MHz band in the 320 MHz band.

Abstract: Provided is a method and device for transceiving a frame in a wireless LAN system. Particularly, an AP transmits a first frame to a first STA via a first band. The AP receives a second frame from a second STA via a second band while the first frame is being transmitted. The first band and the second band are combined with each other as a multi-band. The multi-band simultaneously supports a DL transmission and a UL transmission. The relationship between the first STA and the second STA is a hidden node. A PHY header of the first frame includes channel status information of the second band. An NAV of the first STA is set up on the basis of the channel status information.
