Abstract: A method and a device for transmitting data in a neighbor awareness network (NAN) are provided. A NAN device acquires a NAN association identifier (AID) from a unique identifier and receives a traffic indication map (TIM) information on the basis of a TIM offset. TIME offset is determined on the basis of the NAN AID.

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.

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.
