摘要： A method and a device for transmitting metadata in a WFD are provided. Particularly, a WFD source forms a WFD frame including a WFD header and metadata. The WFD source transmits, to a WFD sink, a packet stream created by packetizing a metadata stream including the WFD frame. The WFD header includes a metadata structure field and a metadata update indicator. The metadata structure field indicates whether the metadata has a video metadata structure or an audio metadata structure. The metadata update indicator indicates that previous metadata is updated such that all of the previous metadata is replaced with new metadata, or that the previous metadata is incrementally updated together with updated metadata.

摘要： A method and a device for positioning a NAN terminal in a wireless LAN system are provided. A first station receives, through a service discovery frame during a preset discovery window, allocation information of an available window for reporting a location estimate value of the first station, location information of a second station located within a distance of one hop from the first station, and location information of a third station located within a distance of at least one hop from the second station. The first station determines the location estimate value of the first station on the basis of the location information of the second station and the location information of the third station. The first station reports the location estimate value of the first station during a section indicated by the allocation information of the available window.

摘要： The present specification relates to a method for transmitting data by a first neighbor awareness networking (NAN) device in a wireless communication system. The method for transmitting data may comprise the steps of: performing a service discovery for a first service with a second NAN device through a service discovery frame (SDF); and exchanging data for the first service with the second NAN device on the basis of the performed service discovery. Here, when at least one of authentication and association is required in transmitting the data for the first service, attribute information which is required for the data transmission among information on authentication attributes and information on association attributes may be included in the service discovery frame.

摘要： 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.

摘要： Proposed are a method and an apparatus in which a plurality of CHIP controllers control an accessory STA in a wireless LAN system in a smart home environment. Particularly, the accessory STA performs a connection procedure for a first CHIP network to which a first controller belongs. The accessory STA receives a set configuration request message from the first controller. The accessory STA transmits a set configuration response message to the first controller. The accessory STA performs a connection procedure for a second CHIP network to which a second controller belongs.
