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: Proposed is a method for determining transmission using a network allocation vector (NAV) in a wireless LAN system. Specifically, after a receiving device receives a trigger frame, which triggers an uplink multiple user transmission, from a transmitting device, whether to transmit an uplink physical layer protocol data unit (PPDU) corresponding to the trigger frame is determined using the NAV of the receiving device. In this case, if the NAV is established by an intra-basic service set (BSS) frame, whether to transmit the uplink PPDU is determined without taking the NAV into consideration.

Abstract: Disclosed herein is an operating method of a station (STA) in a wireless LAN (WLAN) system. The method includes receiving a downlink (DL) physical protocol data unit (PPDU) and sending an uplink (UL) PPDU as a response to the DL PPDU. The DL PPDU may include at least one MAC protocol data unit (MPDU) and the at least one MPDU may include a first high efficiency (HE) control field. The UL PPDU may include at least one MAC protocol data unit (MPDU) and the at least one MPDU may include a second high efficiency (HE) control field. The each of the first and second HE control fields corresponds to an HT control field and comprises a plurality of aggregated HE control subfield. The HT control field includes VHT subfield value set to “1” and HE subfield value set to “1”.

Abstract: An embodiment of the present invention suggests a method in which an access point (AP) obtains channel quality information in a wireless LAN system. The AP transmits, to at least one station (STA), a null data packet announcement (NDP-A) frame including information on transmission of a subsequent null data packet (NDP) frame, and transmits an NDP frame to the at least one station on the basis of information on the NDP-A frame. Further, the AP receives, from the at least one STA, a feedback frame including downlink channel quality information. At this time, the NDP frame includes an L-part for a legacy STA and a high efficiency (HE)-part for a HE STA, wherein the HE-part consists of a HE-signaling A (HE-SIG A) field, a HE-short training field (HE-STF), and a HE-long training field (HE-LTF).
