Abstract: In a wireless local area network system, a station (STA) generates a physical (PHY) protocol data unit (PPDU) including at least one subframe and information related to a subframe length, wherein the subframe may include a medium access control (MAC) protocol data unit (MPDU) and a padding bit. The length of the padding bit may be determined such that the length of the subframes is an integer multiple of a codeword length. The information related to the subframe length may be information on the number of codewords related to the subframe length. A step in which the STA transmits the PPDU may be comprised.

Abstract: Proposed are a method and a device for transmitting data in a wireless LAN system. Specifically, a transmission device receives configuration information of a multi-band formed by aggregating first to third bands. The transmission device carries out channel sensing on the first to third bands. The transmission device transmits data to a receiving device on the basis of the result of the channel sensing. The first band comprises a first primary channel and a first secondary channel; the second band comprises a second primary channel and a second secondary channel; and the third band comprises a third primary channel and a third secondary channel.

Abstract: A method and an apparatus for transmitting a PPDU on the basis of an S-TDMA in a wireless LAN system are presented. Particularly, an AP transmits a trigger frame to a first STA and a second STA. The AP receives, on the basis of the trigger frame, a first trigger-based frame from the first STA and a second trigger-based frame from the second STA. The trigger frame includes a common information field and a user information field. The common information field includes S-TDMA indication information enabling the S-TDMA to be performed. The user information field includes: allocation information on a first RU to which the first trigger-based frame and the second trigger-based frame are transmitted; first symbol offset information on the first trigger-based frame; and second symbol offset information on the second trigger-based frame.
