Abstract: The present document relates to a wireless communication system and, more specifically, to a method for flexibly supporting resource allocation in a wireless LAN system, and a method and an apparatus for signal transmission using the same. To this end, a first STA configures a radio frame comprising: a signaling (SIG) field including control information; and a data field in which data can be transmitted via a discontinuous channel or a channel having a bandwidth size that is supported by a legacy system. When the first STA transmits the configured radio frame to a second STA, the SIG field preferably comprises: information about a full bandwidth in which data can be transmitted via the data field; and null indicator information indicating a channel region of the full bandwidth that is not used in data transmission, or used channel indicator information indicating a channel region of the full bandwidth that is used in data transmission.

Abstract: The present specification relates to a method for transmitting signals by a station (STA) which operates in a wireless LAN system. Here, the method for transmitting signals by a station can comprise: a step of receiving a first frame for converting a power saving (PS) mode, from an access point (AP) station, to an awake mode; and a step of transmitting a second frame for informing the awake mode of the station in response to the first frame. Here, the second frame can be a null data packet (NDP) frame.

Abstract: The present disclosure relates to a method of receiving, by a station that operates in a wireless LAN system, a signal in a wireless communication system. In this case, it is possible to include the steps of receiving a PPDU that includes an MAC frame, decoding the MAC frame, and checking information in the MAC frame based on the MAC header of the MAC frame that includes a first address field and a second address field. In this case, when the PPDU includes the identification information (ID) of a station, the MAC header may include only one of any of the first address field and the second address field.

Abstract: Provided are a method and an apparatus for transmitting metadata in a WFD. More particularly, a WFD source transmits, to a WFD sink, a first transmission stream in which an audio stream and a video stream are superimposed and multiplexed. The WFD source receives, from the WFD sink, a first RTSP request message for requesting transmission of metadata for audio data and video data during the transmission of the first transmission stream. The WFD source transmits, to the WFD sink, a first RTSP response message in response to the first RTSP request message during the transmission of the first transmission stream. The WFD source transmits, to the WFD sink, a metadata stream including the metadata and a second transmission stream in which the audio stream and the video stream are superimposed and multiplexed.

Abstract: Disclosed are a method for data communication between NAN devices, and a NAN device for performing data communication. The method for data communication between the NAN devices comprises the steps of: receiving a service discovery frame from a second NAN device by a first NAN device; transmitting a TIM element to a second NAN device by the first NAN device having received the service discovery frame and being triggered by a user action, wherein the TIM element includes information related to data buffered with respect to the second NAN device; performing, by the first NAN device, an authentication procedure and an association procedure with the second NAN device on the basis of a request of the second NAN device having received the TIM element; transmitting a falling frame from the second NAN device by the first NAN device; and transmitting, by the first NAN device, the data buffered with respect to the second NAN device, to the second NAN device in response to the falling frame.
