    Abstract: A method for transmitting, by an access point (AP), a wake-up radio (WUR) packet in a wireless local area network (WLAN) system, according to an embodiment of the present invention, comprises the steps of: setting a MAC header comprising at least two of type information of the WUR packet, receiver address information, and transmitter address information; and transmitting the WUR packet comprising the MAC header, wherein in setting the MAC header, when the WUR packet is a broadcast WUR packet, the AP omits the receiver address information from the MAC header and sets the transmitter address information, and wherein whether or not an STA belonging to the AP should perform a primary connectivity radio (PCR)-on procedure after receiving the broadcast WUR packet may be instructed through the type information of the WUR packet.

    Abstract: One embodiment of the present specification may provide a method for transmitting data by a first NAN device in a wireless communication system. Here, the method for transmitting data by the first NAN device may comprise the steps of: exchanging a service discovery frame (SDF) with a second NAN device using a common channel; switching the first NAN device to a first channel during a first interval; checking whether the switched first channel is available during a second interval; and if the first channel is available, transmitting data to the second NAN device via the first channel. Here, information on the first interval and the second interval with respect to the first channel may be included in the service discovery frame.

    Abstract: A method for performing uplink Orthogonal Frequency Division Multiple Access (UL OFDMA) based random access to an Access Point (AP) by a Station (STA) in a Wireless Local Area Network (WLAN) system is proposed. For the purpose, the STA sets a random value within an OFDMA Contention Window (CWO) as an OFDMA Back-Off (OBO) value, receives a beacon frame from the AP, the beacon frame including transmission start time information of one or more Trigger Frames for Random Access (TF-Rs), decrements the OBO value based on reception of the one or more TF-Rs, and if the OBO value reaches 0, transmits a random access request frame in resources selected randomly from among resources allocated to the STA.

    Abstract: In the present specification, provided is a method for relaying, by a NAN proxy server, data communication in a wireless communication system. Here, the method for relaying data communication by an NAN proxy server may comprise the steps of: transmitting server capability attribute information of the NAN proxy server to a first NAN proxy client; receiving connection capability attribute information from the first NAN proxy client; transmitting proxy relay request attribute information to the first NAN proxy client; receiving proxy relay response attribute information from the first NAN proxy client; and performing scheduling for the first NAN proxy client and relaying data communication to the first NAN client. Here, the proxy relay request attribute information may be transmitted if information on a direct connection failure is included in the connection capability attribute information.

    Abstract: Disclosed are a data communication method between NAN devices operating in power save mode and a data communication-performing NAN device operating in power save mode. The data communication method between NAN devices operating in power save mode may comprise the steps of: a first NAN device receiving a discovery window cycle information element; on the basis of the window cycle information element, the first NAN device setting a discovery window cycle and a discovery window included in the discovery window cycle; the first NAN device operating on the discovery window in an awake state and receiving, from a second NAN device, a TIM information element containing information on data buffered on the first NAN device; and on the basis of the TIM information element, the first NAN device setting a listening window or a power save window within the discovery window cycle after the discovery window.
