Abstract: Proposed is a method and device for receiving data in a wireless LAN system. Specifically, an AP transmits a trigger frame to a first to a third station (STA) through a multi-band. The AP receives data from the first to third STAs on the basis of the trigger frame. In the multi-band, a first band to a third band are combined. The trigger frame includes a common information field and a first to a third user information field. When the first and second STAs are associated with the first band, the first user information field includes user information relating to the first and second STAs. When the second and third STAs are associated with the second band, the second user information field includes user information relating to the second and third STAs. When the third STA is associated with the third band, the third user information field includes user information relating to the third STA.

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: 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.

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.
