Abstract: Presented in the present disclosure are a method and a device for defining an A-PPDU header in a DL A-PPDU and configuring information indicated by the A-PPDU header in a wireless LAN system. Particularly, a reception STA receives a DLA-PPDU from a transmission STA. The reception STA decodes a DL A-PPDU. The DL A-PPDU comprises an A-PPDU header for a 320 MHz band, a first PPDU for a primary 160 MHz channel, and a second PPDU for a secondary 160 MHz channel. The A-PPDU header is generated on the basis of a first phase rotation value. The first phase rotation value is a phase rotation value defined in an EHT wireless LAN system with respect to a 320 MHz band.

Abstract: Disclosed are a method and apparatus for carrying out communication on the basis of operating mode control information in a wireless LAN system. The method by which a first STA carries out communication in a wireless LAN system comprises the steps of: receiving, from a second STA, a frame including first information related to a first channel width less than or equal to a first maximum bandwidth and second information related to a second channel width less than or equal to a second maximum bandwidth; and carrying out communication on the basis of the first information, or the first information and the second information, wherein a value of the first information when a combination of the first information and the second information indicates the second maximum bandwidth may be the same as a value of the first information when the first information alone indicates the first maximum bandwidth.

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 20 MHz 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.
