Abstract: One embodiment of the present invention relates to a method for transreceiving signals through a neighbor awareness networking (NAN) terminal in a wireless communication system, comprising the steps of: receiving a NAN synchronization beacon frame and/or a NAN discovery beacon frame; and accessing a NAN cluster which has transmitted the NAN discovery beacon frame, wherein when the NAN cluster is a coordinated NAN cluster, the NAN terminal maintains the state at the time of accessing the NAN cluster.

Abstract: One embodiment of the present invention relates to a method for shifting the state of a neighbor awareness networking (NAN) terminal in a wireless communication system, comprising the steps of: receiving a first synchronization beacon frame; and receiving a second synchronization beacon frame after the first sync beacon frame has been received, wherein the state of the NAN terminal is shifted to a state capable of transmitting synchronization beacon frames regardless of a received signal strength indicator (RSSI) of the synchronization beacon frames, when anchor master rank information included in the first synchronization beacon frame and anchor master rank information included in the second synchronization beacon frame are different, and the NAN terminal is in a non-master non-sync state.

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: A wireless communication system is disclosed. Disclosed herein are methods for transmitting a physical uplink control channel (PUCCH) signal in a wireless communication system, which includes setting transmit power for the PUCCH signal, and an apparatus thereof. If the PUCCH signal is transmitted on a subframe configured for a scheduling request (SR), the PUCCH signal includes one or more hybrid automatic repeat request acknowledgement (HARQ-ACK) bits and an SR bit. When determining the transmit power for the PUCCH, the SR bit is selectively considered depending on whether or not a transport block for an uplink shared channel (UL-SCH) is present in the subframe.
