Abstract: Disclosed are a transmission or reception method and device based on distributed allocation of multiple resource units in a wireless LAN system. A method performed by a station (STA) in a wireless LAN system, according to one embodiment of the present disclosure, comprises the steps of: receiving, from an access point (AP), a trigger frame including distributed resource allocation information related to a plurality of resource units (RUs) that are allocated to the STA; and performing uplink transmission to the AP on the basis of the distributed resource allocation information, wherein the distributed resource allocation information may be indicated on the basis of at least an RU allocation subfield included in one user information field in the trigger frame.

Abstract: Proposed are a method and a device for receiving a PPDU on the basis of control information related to an operating channel in a wireless LAN system. Specifically, a reception STA receives control information from a transmission STA. The reception STA receives a PPDU from the transmission STA on the basis of the control information. The control information includes an EHT operation element and a UHR operation element. The EHT operation element includes a first channel bandwidth subfield, a first CCFS subfield, and a second CCFS subfield. The UHR operation element includes a second channel bandwidth subfield, a third CCFS subfield, and a fourth CCFS subfield.

Abstract: Proposed are a method and a device that receive a PPDU on the basis of control information related to channelization of a 6 GHz band in a WLAN system. Specifically, a receiving STA receives the PPDU from a transmitting STA. The receiving STA decodes the PPDU to obtain the control information related to the channelization of the 6 GHz band. The receiving STA decodes a data field of the PPDU on the basis of the control information. The 6 GHz band includes first to seventh 160 MHz channels, first to third 320-1 MHz channels, first to third 320-2 MHz channels, first and second 480-1 MHz channels, or first and second 480-2 MHz channels.

Abstract: Disclosed are a method and a device for a sounding procedure related to an aggregated-physical layer protocol data unit (A-PPDU) support in a WLAN system. A method for performing a sounding procedure by a first station (STA) in a wireless LAN system comprises the steps of: receiving at least one null data PPDU (NDP) announcement frame from a second STA on a first frequency unit associated with a first type PPDU format and a second frequency unit associated with a second type PPDU format; receiving at least one NDP from the second STA on the first frequency unit and the second frequency unit; receiving at least one trigger frame from the second STA on the first frequency unit and the second frequency unit; and transmitting a feedback frame for at least one of the first frequency unit and the second frequency unit to the second STA, wherein the at least one NDP may be received from the second STA on the basis of a first type of training sequence and a second type of training sequence.
