Abstract: A method for allowing a terminal to reuse 60 GHz P2P (Peer to Peer) connection in a wireless communication system is disclosed. The method for reusing the 60 GHz P2P (Peer to Peer) connection by the terminal includes performing first Wi-Fi Display (WFD) session connection based on a Real Time Streaming Protocol (RTSP) message, completing the first WFD session connection, and performing second WFD session connection. The RTSP message includes a first parameter for indicating whether the 60 GHz P2P connection will be retained after completion of the first WFD session connection, and a second parameter for indicating whether the 60 GHz P2P connection will be reused after completion of the first WFD session connection. When the first parameter indicates that the 60 GHz P2P connection is not retained and the second parameter indicates that the 60 GHz P2P connection is reused, information associated with the 60 GHz P2P connection is exchanged when the first WFD session connection is completed.

Abstract: Disclosed are a method and a device for operation based on a power save mode in a WLAN. The method for operation based on a power save mode may comprise steps in which: an STA, which has been switched to an awake state, transmits a PS-poll frame to an AP on the basis of the transmission cycle of a beacon frame; the STA receives an ACK frame from the AP in response to the PS-poll frame; after receiving the ACK frame, the STA overhears a different BSS frame; and within a preset time upon overhearing the different BSS frame, the STA determines whether or not to maintain the awake state on the basis of whether or not a power management control frame has been transmitted from the AP.

Abstract: Proposed is a method for receiving a Wi-Fi service by a wireless LAN station supporting an application service platform (ASP). Specifically, the Wi-Fi service can be received through at least two connection techniques, for example, a Wi-Fi direct connection of Wi-Fi infrastructure connection may be used. The wireless LAN station having an ASP may detect information on each of the connection techniques and may be provided with the Wi-Fi service using one of the connection techniques. In addition, when a change in a communication environment or the like occurs, the connection technique may be switched and, in this case, signaling for switching the connection technique may be used.

Abstract: Disclosed are a method and an apparatus for reporting information about a transmission failure frame. The method for reporting information about a transmission failure frame in a wireless LAN may comprise the steps of: creating, by an STA, the retransmission frame includes information about the transmission failure frame, the information about the transmission failure frame includes timestamp information and duration information, the timestamp information includes information about the transmission start time of the transmission failure frame, and the duration information includes information about the transmission period of the transmission failure frame.

Abstract: The present disclosure relates to a wireless communication system, and in particular to a data transmission operation of an AP in a wireless LAN system. To this end, the AP may obtain information on a STA located at an overlapping basic service set (OBSS) from among STAs connected to the AP, and determines, based thereon, (1) whether to transmit data from the AP through a downlink oriented channel or a general channel different from the downlink oriented channel, or (2) whether to use one or more of a distributed coordination function (DCF) procedure and an enhanced distributed channel access (EDCA) procedure.

Abstract: A power save mode-based operating method and device in a WLAN are disclosed. The power save mode-based operating method in the WLAN may include: transmitting, by an STA, a first trigger frame to an AP; receiving, by the STA, a downlink frame transmitted by the AP based on the first trigger frame on a first service section; receiving, by the STA, traffic indication information from the AP on a second service section after the reception of the downlink frame; determining, by the STA, the presence or absence of a pending downlink frame at the AP based on the traffic indication information on the second service section; and determining, by the STA, a power saving mode based on the presence or absence of the pending downlink frame.
