Synchronization of a peer-to-peer communication network
In an ad hoc peer-to-peer communications network, timing synchronization can be facilitated between two or more nodes based on respective timing adjustments. A sequence of timing synchronization time intervals can be determined based on a first timing reference received from a source. A symbol timing can be determined and included in a first signal transmitted during a dedicated time interval, which can be a chosen fraction of one of the timing synchronization time intervals. In the remaining portion of the time interval, such as a non-chosen fraction, a second signal that includes a second timing reference can be received. Based on the symbol timing and the second timing reference, a timing adjustment can be determined and timing of each node adjusted accordingly.
