Abstract
Proposed are a method and device for receiving an A-PPDU in a wireless LAN system. Specifically, a reception STA receives an A-PPDU from a transmission STA and decodes the A-PPDU. The A-PPDU includes a first PPDU for a primary 160 MHz channel and a second PPDU for a secondary 160 MHz channel. A first signal field includes information about a bandwidth in which the first PPDU is transmitted. The information about the bandwidth in which the first PPDU is transmitted includes information about a first preamble puncturing pattern punctured in a unit of a 20 MHz channel in the primary 160 MHz channel. A second signal field includes information about a second preamble puncturing pattern.
