    摘要: In a wireless local area network system, a reception multi-link device (MLD) may not transmit a CTS frame, even if the reception multi-link device receives an RTS frame via a second link, in the case that an STA operating via a first link is a TXOP responder. In detail, the reception MLD may include at least one non-simultaneous transmit and receive (NSTR) link pair. A first STA affiliated with the MLD may determine to respond with the CTS frame to the RTS frame. The first STA does not respond with the CTS frame based on another STA being a transmission opportunity (TXOP) responder on another link.

    摘要: A method and an apparatus for transmitting an EHT PPDU to a wireless LAN system are presented. Particularly, a transmission device generates an EHT PPDU, and transmits the EHT PPDU to a reception device through a 320 MHz band of which a partial band is punctured on the basis of an RF. 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 method and a second method. The first method is for acquiring an optimum PAPR in the L-LTF. The second method is for acquiring an optimum PAPR on the basis of a maximum transmission bandwidth supported by the RF. The first phase rotation value is acquired on the basis of a second phase rotation value and a third rotation value. The second phase rotation value is a phase rotation value which repeats a phase rotation value that is defined with respect to an 80 MHz band in an 802.11ax system. The third phase rotation value is a phase rotation value that is defined by 80 MHz band units in the 320 MHz band.

    摘要: Proposed are a method and device for acquiring information on links between MLDs in a wireless LAN system. Specifically, a receiving MLD transmits a probe request frame to a transmitting MLD through a first link. The receiving MLD receives a probe response frame from the transmitting MLD through the first link. The transmitting MLD comprises: a first transmitting STA operating in the first link; a second transmitting STA operating in a second link; and a third transmitting STA operating in a third link. The receiving MLD comprises a first receiving STA operating in the first link. When the first receiving STA requests for information on the second and third links, the probe request frame includes link identifiers for the second and third links. When the first receiving STA requests for information on all the links, the probe request frame does not include link identifiers for all the links.

    摘要: 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.
