Abstract: Proposed is a method and device for receiving data in a wireless LAN system. Specifically, an AP transmits a trigger frame to a first to a third station (STA) through a multi-band. The AP receives data from the first to third STAs on the basis of the trigger frame. In the multi-band, a first band to a third band are combined. The trigger frame includes a common information field and a first to a third user information field. When the first and second STAs are associated with the first band, the first user information field includes user information relating to the first and second STAs. When the second and third STAs are associated with the second band, the second user information field includes user information relating to the second and third STAs. When the third STA is associated with the third band, the third user information field includes user information relating to the third STA.

Abstract: A method for providing ACK and/or NACK information in a WLAN system is proposed. The method proposes configuring a second PPDU in response to receiving a first PPDU. The second PPDU includes a legacy part, a control signal field, and a training field. The training field of the second PPDU may be configured based on whether the data field of the first PPDU is successfully received. The training field may be configured based on a first LTF sequence for indicating a successful reception of the first PPDU. The training field may be configured based on a second LTF sequence for indicating an error of the first PPDU.

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: A method and an apparatus for transmitting and receiving PPDU on the basis of FDR in a wireless LAN system are presented. Specifically, an AP generates FDR indication information that FDR can be performed. The AP transmits a DL PPDU including the FDR indication information to a first STA. The AP receives a UL PPDU from the first STA. The DL PPDU includes a legacy signal field, a first signal field, a second signal field, a third signal field, and a DL data field. The second signal field includes information on an RU placement in the entire frequency band and allocation information for a first RU to which the DL data field is allocated. The third signal field includes allocation information for a second RU to which the UL PPDU is allocated on the basis of the information on the RU placement. The allocation information for the second RU includes a bitmap of whether the UL PPDU is allocated in units of 26 RUs.
