The present disclosure describes methods and apparatus for synchronizing beacon transmissions. Synchronization beacons may be transmitted from multiple nodes during a same time slot of a discovery window with accommodation for managing potential signal interference. For certain example embodiments, a first wireless communication device includes a transceiver and a synchronization beacon transmission system. A transceiver may be configured to transmit a synchronization beacon in a neighbor awareness networking (NAN) environment, wherein the NAN environment includes multiple wireless communication devices arranged in a cluster. A synchronization beacon transmission system may be configured to determine a transmission time based at least partially on an operation that separates the wireless communication devices of the cluster into multiple groups. A synchronization beacon transmission system may further be configured to cause the transceiver to transmit the synchronization beacon responsive to the determined transmission time.
