1. A method performed by a network entity for synchronizing one or more first fronthaul network units with one or more second fronthaul network units across a packet-based fronthaul network carrying Time-Division Duplex, TDD, radio transmissions, the method comprising:
obtaining information indicating uplink, UL, time periods and downlink, DL, time periods in the packet-based fronthaul network occupied by the TDD radio transmissions transmitted and/or received by the one or more second fronthaul network units over a radio interface; and
scheduling packet-based synchronization messages for transmission between at least the one or more first fronthaul network units and the one or more second fronthaul network units over the packet-based fronthaul network, the scheduling of the packet-based synchronization messages being based on the obtained information.
