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: An example according to the present specification relates to a method for performing low latency communication. A transmission STA and a reception STA may exchange a low latency communication request frame and a low latency communication response frame. The low latency communication request frame may include first information for performing the low latency communication. The first information may include at least one among information for requesting parameters for the low latency communication and information about traffic. In addition, the low latency communication response frame may include second information for performing the low latency communication. The second information may include information about the parameters for the low latency communication. The reception STA and the transmission STA may perform the low latency communication with the transmission STA on the basis of the first information and the second information.

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.

Abstract: Provided are a method for beamforming training and an apparatus using the same. An STA receives a beacon frame from an AP during a BTI. The STA transmits SSW frames during an A-BFT. The beacon frame comprises an A-BFT length indicating the number of a plurality of SSW slots included in the A-BFT, a FSS field indicating the number of the SSW frames allowed in one SSW slot among the plurality of SSW slots, and information about the type of the SSW frames used in one SSW slot. The information about the type of the SSW frames indicates that the SSW frames are determined to be one from among first type SSW frames and second type SSW frames. The second type SSW frames have a smaller size than that of the first type SSW frames. If the SSW frames are determined to be the second type SSW frames, the FSS field indicates the number of the second type SSW frames that can be transmitted in one SSW slot.
