Abstract: A method and an apparatus for receiving an ACK frame in a WLAN system are proposed. Specifically, a first STA transmits a plurality of first MPDUs in a first transmitting TDD slot to a second STA. The first STA receives a first ACK frame for the plurality of first MPDUs from the second STA in a first receiving TDD slot. The first STA transmits a second MPDU to the second STA in a second transmitting TDD slot. The first STA receives a second ACK frame for the second MPDU from the second STA in a second receiving TDD slot.

Abstract: A method performed by a first STA in a wireless local area network (WLAN) according to various embodiments may comprise transmitting or receiving a TWT setup request message and a TWT setup response message. The first STA may perform a TWT operation on the basis of the TWT setup request message and the TWT setup response message. The TWT setup request message and the TWT setup response message may be transmitted or received through a first link included in multiple links. The first STA may set the first link to be in an awake state in order to perform the TWT operation through the first link.

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.

Abstract: Provided are a method and apparatus for transmitting/receiving a signal based on a power saving (PS) mode in a wireless local area network (WLAN) system. Specifically, a first station (STA) determines the PS mode in a time division duplex (TDD)-based service period (SP), and transmit the signal to the second STA or receive the signal from the second STA based on the PS mode. The SP includes a plurality of TDD slots. The plurality of TDD slots include an unassigned TDD slot, an assigned Tx TDD slot, and an assigned Rx TDD slot. In the unassigned TDD slot, a PS mode of the first STA is determined as a doze state, and a PS mode of the second STA is determined an awake or doze state. In the assigned Rx TDD slot, the PS mode of the first STA is determined as the awake state, and the PS mode of the second STA is determined as the awake state. In the assigned Tx TDD slot, the PS mode of the first STA is determined as the awake or doze state, and the PS mode of the second STA is determined as the awake state.
