Abstract: A method and a device for receiving uplink data in a WLAN system are proposed. Specifically, an AP transmits a beacon frame to a first STA or a second STA. The AP receives uplink data from the first STA or the second STA based on the beacon frame. The beacon frame includes information about a transmission mode for the uplink data for each channel in a first band and each channel in a second band. The uplink data is transmitted based on contention when the information about the transmission mode for the uplink data is set to a first value. The uplink data is transmitted based on scheduling when the information about the transmission mode for the uplink data is set to a second value.

Abstract: A method and a device for transmitting and receiving a PPDU on the basis of an FDD in a wireless LAN system are presented. Particularly, an AP transmits a trigger frame to a first STA and a second STA. The AP transmits a first downlink (DL) PPDU to the first STA on the basis of the trigger frame. The AP transmits a second DL PPDU to the second STA on the basis of the trigger frame. The AP receives a first uplink (UL) PPDU from the second STA on the basis of the trigger frame. The trigger frame includes bandwidth information of a primary channel and a secondary channel. The first DL PPDU is transmitted through the primary channel. The second DL PPDU and the first UL PPDU are transmitted through the secondary channel. The first and second DL PPDU are simultaneously transmitted. The first UL PPDU is received after a preset period after the second DL PPDU is transmitted.

Abstract: Proposed are a method and an apparatus for transmitting a signal by performing MIMO beamforming in a wireless LAN system. Specifically, a first STA performs MIMO beamforming during a second STA and TDD-based SP. The first STA transmits a signal to the second STA on the basis of a result of the MIMO beamforming. The SP includes a plurality of TDD slots. The MIMO beamforming includes a first sub-step and a second sub-step. In the first sub-step, after receiving a first MIMO beamforming setup frame from the second STA, the first STA transmits a second MIMO beamforming setup frame in the first allocated TDD slot among the TDD slots allocated to the first STA. In the second sub-step, after receiving a first MIMO beamforming feedback frame from the second STA, the first STA transmits a second MIMO beamforming feedback frame in a first allocated TDD slot among the TDD slots allocated to the first STA.

Abstract: According to one embodiment of the present specification, provided is a method by which a station (STA) transmits, through a plurality of channels, signals in a wireless LAN (WLAN) system. The method for transmitting signals comprises the steps of: allowing an STA to transmit a packet for an ISS; allowing the STA to receive a packet for an RSS; allowing the STA to transmit a packet for a SSW feedback; and allowing the STA to receive a packet for an SSW ACK, wherein the packet for the SSW feedback and the packet for the SSW ACK can include a field for indicating whether the packet for the ISS and the packet for the RSS are transmitted into the short SSW packet.
