Abstract

In some embodiments, one or more wireless stations operate to configure direct communication with neighboring mobile stations, e.g., direct communication between the wireless stations without utilizing an intermediate access point. Embodiments of the disclosure relate to a mechanism for a wireless station to discover a neighboring peer wireless station, e.g., via peer-to-peer Wi-Fi communications, receive a synchronization beacon(s) from the neighboring peer wireless station, and synchronize timing with the neighboring peer wireless station based at least in part on the synchronization beacon(s). In addition, the wireless station may transmit, e.g., via Wi-Fi peer-to-peer communications, a data beacon to one or more neighboring wireless devices stations, wherein the one or more neighboring wireless stations are configured to synchronize timing with the wireless station based on the data beacon.
