1. A method comprising:
performing a reverse time synchronization procedure between a sending device and a target receiving device;
determining a Time Error (TE) between the sending device and the target receiving device based on the reverse time synchronization procedure wherein determining the TE based on the reverse time synchronization procedure comprises performing other reverse time synchronizations procedures between the sending device and the target receiving device in addition to the reverse time synchronization procedure and determining the TE based on a statistical moment of the other reverse time synchronization procedures and the reverse time synchronization procedure; and
scheduling a gate time on the target receiving device based on the determined TE.
