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 and a device for transmitting and receiving PPDU on the basis of FDR in a wireless LAN system are presented. More particularly, an AP transmits a trigger frame to an STA. The AP transmits downlink (DL) PPDU to the STA on the basis of the AP trigger frame. The AP receives uplink (UL) PPDU from the STA on the basis of the trigger frame. The trigger frame includes a first common information field. The first common information field includes a trigger type field, a length field, and a bandwidth field. The length field comprises information on the length of the longest PPDU of the DL PPDU and the UL PPDU. The bandwidth field comprises information on the total bandwidth over which the DL PPDU and the UL PPDU are transmitted. The DL PPDU and the UL PPDU are transmitted and received on the basis of FDR.

Abstract: Presented are a method and device for transmitting a wakeup packet in a wireless LAN system. Specifically, the transmission device configures a first wakeup packet having a first data rate by using a first sync field, and a second wakeup packet having a second data rate by using a second sync field. The transmission device transmits the first and second wakeup packets to a receiving device. Here, an OOK scheme is applied to the first and second wakeup packets to configure the first and second wakeup packets as an ON signal or an OFF signal. The first sync field includes a first sequence, and the second sync field includes a second sequence which is a complementary sequence to the first sequence. The number of coefficient 1 and coefficient 0 included in the first sequence is the same. The first and second sequences have a 32 bit length, and each bit of the first and second sequences has a duration of 2 μs.
