Abstract: Proposed are a method and an apparatus for transmitting data in a wireless LAN system. Particularly, an AP transmits a PPDU to one STA. The AP transmits data to the one STA over a first NCCB band or a second NCCB band on the basis of the PPDU. The PPDU includes a first signal field and a second signal field. The first NCCB band is a 40 MHz or 60 MHz band generated by bonding a discontinuous 20 MHz band in an 80 MHz band. The second NCCB band is an 80 MHz, 100 MHz, 120 MHz, or 140 MHz band generated by bonding a discontinuous 20 MHz band in a 160 MHz band. The first signal field includes first information and second information. The first information is NCCB indication information on whether or not an NCCB can be performed. The second information is NCCB bandwidth information for a band to be used for transmitting the PPDU from the first NCCB band and the second NCCB band.

Abstract: Disclosed is a signal processing method for changing an operating mode for transmitting a PPDU in a wireless LAN system. Specifically, a first station transmits, to a second station, the number of spatial streams supported by the first station, and a first instructional information instructing a change of the operating mode indicating a channel bandwidth. The first station applies the first instructional information after receiving an ACK therefor. The first instructional information comprises an operating mode indicator for indicating whether the operating mode is a receive operating mode (ROM) or a transmit operating mode (TOM).
