Abstract: In the present specification, a method may be provided in which a NAN terminal exchanges frames in a wireless communication system. Here, the method in which a NAN terminal exchanges frames may include the steps of: transmitting a first frame, in which a first NAN terminal requests first properties information, to a second NAN terminal, and receiving a second frame for the first properties information from the second NAN terminal. Here, when the first frame is a service discovery frame, the first properties information may be set on the basis of a first field value of the first frame, and when the first frame is a GAS frame, the first properties information may be set as proxy service information.

Abstract: The present invention relates to a method for a NAN proxy client transitioning a state in a wireless communication system. Here, the method for a NAN proxy client transitioning a state may comprise the steps of: the NAN proxy client transitioning, to a NAN proxy server, a request message requesting the escrowing of a proxy service; receiving a response message from the NAN proxy server; performing registration to the NAN proxy server on the basis of the response message; and the state of the NAN proxy client transitioning. Here, if the registration to the NAN proxy server is performed, the state of the NAN proxy client can be transitioned to a first state.

Abstract: The present document relates to a method for efficiently performing uplink multi-user transmission in a wireless LAN system and an apparatus therefor. To this end, an access point (AP) may transmit a downlink multi-user frame to a plurality of STAs, receive an uplink frame including an acknowledgement/non-acknowledgement (ACK/NACK) signal for the downlink multi-user frame and an uplink scheduling request signal from at least two STAs among the STAs, transmit a downlink frame including uplink scheduling information to the at least two STAs on the basis of the uplink scheduling request signal, and receive an uplink multi-user frame including data from the at least two STAs in response thereto. Here, an SIG field of the downlink frame preferably comprises an indicator indicating that the downlink frame includes uplink multi-user scheduling information.

Abstract: Disclosed are a power save mode-based operating method and apparatus in a wireless LAN. The power save mode-based operating method in a wireless LAN comprises the steps of: receiving, by an STA, overheard BSS information from an AP; receiving, by the STA, a PPDU, wherein the PPDU includes information on a BSS having transmitted the PPDU; determining, by the STA, whether the overheard BSS information includes the information on the BSS; and switching an awake state to a doze state when the STA determines whether the overheard BSS information includes the information on the BSS, wherein the overheard BSS information can include the information on at least one overheard BSS for transmitting a frame enabled to be overheard by the AP.

Abstract: A method for performing 60 GHz WFD (Wi-Fi Display) connection by a first terminal in a wireless communication system is disclosed. The method includes transmitting, by the first terminal, a message requesting 60 GHz WFD connection to a second terminal through an access point (AP); and receiving a message accepting 60 GHz WFD connection from the second terminal through the access point (AP). The 60 GHz WFD connection request message includes capability information indicating whether the first terminal supports 60 GHz. The 60 GHz WFD connection accept message includes capability information indicating whether the second terminal supports operation at 60 GHz. The messages are exchanged with each other on the basis of at least one of 2.4 GHz and 5 GHz.

Abstract: The present document relates to a backoff procedure and apparatus for efficiently accessing a broadband channel in a wireless LAN system. To this end, a station performs a clear channel assessment (CCA) operation in each of a plurality of channels, and when one or more of the plurality of channels is/are not used and the one or more channels is/are not used for frame transmission in the basic service set (BSS) of its/their station, the station is characterized in that it performs or re-performs a backoff procedure in the one or more channels. When a backoff counter value becomes zero according to the backoff procedure, the station may transmit a frame through the one or more channels.
