Abstract
An approach is disclosed for synchronization of frequency and/or phase in a full duplex network. The method may comprise sending a timing beacon over a single full duplex radio channel from a timing master to a timing slave; receiving the timing beacon over the single full duplex radio channel at the timing slave; sending a retransmitted beacon over the single full duplex radio channel from the timing slave to the timing master; and sending a delta of the timing beacon and the retransmitted beacon from the timing master to the timing slave. The beacon may contain a timestamp. The retransmitted beacon may include a delay calculation. A hybrid analog/digital self-interference cancellation system may be used at the timing master or the timing slave. The method may also include simultaneously sending and receiving the synchronization information over the single full duplex radio channel.
