Abstract
A method for communication includes obtaining a timing signal from a timing synchronization reference source, computing a system frame number (SFN)—direct frame number (DFN) offset, creating a timing fingerprint using the timing signal and the SFN-DFN offset, the timing fingerprint also comprising additional timing information, entering the timing fingerprint into a database, continually updating the timing fingerprint, determining whether the timing signal remains within a threshold, if the timing signal exceeds the threshold, iterating the timing fingerprint, verifying the timing fingerprint to determine whether there is a timing inconsistency between a most recent timing fingerprint and current time, if the timing fingerprint is verified, using the SFN-DFN offset to derive current DFN timing to decode a sidelink control information (SCI) communication, and if the SCI communication is decoded, using the timing signal for communicating over a sidelink communication channel.
