Abstract: A method for transmitting an uplink frame in a wireless LAN system according to an embodiment of the present specification comprises the steps in which: a user STA configures a backoff counter for contention-based channel access according to first parameter information for multiple users when a first trigger frame for uplink transmission of the multiple users is received from an AP; the user STA performs a countdown operation on the basis of the backoff counter configured according to the first parameter information; the user STA interrupts the countdown operation in order to transmit a trigger-based uplink frame in response to a second trigger frame when the second trigger frame is received; and the user STA resumes the countdown operation, which has been interrupted, when an ACK frame corresponding to the trigger-based uplink frame is not received.

Abstract: A method for a WLAN system including transmitting, by a first station (STA), a trigger frame triggering uplink multi-user (UL MU) transmission from a second STA, in which the trigger frame includes preference information related to an access category (AC) type for an aggregation frame to be generated by the second STA and limit information related to a maximum number of traffic identifiers (TIDs) for the aggregation frame. In response to the trigger frame, the first STA may receive a UL frame configured based on the aggregation frame and a Quality of Service (QoS) null frame which has an acknowledgement (ACK) policy field being set to no ACK. When the QoS null frame is aggregated, the preference information and the limit information may be disregarded.

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.
