Claim of US Patent No. 10,142,950

1. A method of transceiving signals, which are transceived by a neighbor awareness networking (NAN) terminal in a wireless communication system, the method comprising:receiving a NAN synchronization beacon frame comprising information indicating whether a corresponding NAN cluster is a coordinated NAN cluster or not; and
joining the corresponding NAN cluster based on a first type operation or a second type operation according to whether the information indicates the corresponding NAN cluster is the coordinated NAN cluster,
wherein the first type operation comprises performing an anchor master selection by comparing an anchor master rank value included in the NAN synchronization beacon frame with a stored anchor master rank value in the NAN terminal and performing a state transition according to the anchor master selection,
wherein the second type operation comprises maintaining a state corresponding to a Non-Master Non-Synchronization State at the time of joining the corresponding NAN cluster without performing the anchor master selection,
wherein the Non-Master Non-Synchronization State is a state in which a device cannot transmit the NAN synchronization beacon frame and a NAN discovery beacon frame, and
wherein the coordinated NAN cluster comprises one or more devices having a master preference equal to or greater than a specific value.
