Methods, systems, and devices for wireless communications are described that provide for timing synchronization among one or more time sensitive network (TSN) endpoints via a wireless communications network. A data flow may be established via the wireless communications network, in which one or more system messages associated with the data flow may provide timing information for the data flow. A first node within the wireless communications network may receive a request for establishing such a data flow with a user equipment (UE). The first node may receive timing information for the data flow via one or more system messages associated with the data flow, and establish the data flow based at least in part on the timing information.
