Abstract
A reverse time synchronization may be performed between a sending device and a receiving device. Then a Time Error (TE) between the sending device and the receiving device may be determined based on the reverse time synchronization. A gate time on the receiving device may be scheduled based on the determined TE.
Claims14
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.

A system comprising:
- a memory storage;
- and
- a processing unit coupled to the memory storage, wherein the processing unit is operative to:
- perform a reverse time synchronization procedure between a sending device and a target receiving device;
- determine a Time Error (TE) between the sending device and the target receiving device based on the reverse time synchronization procedure wherein the processing unit being operative to determine the TE based on the reverse time synchronization comprises the processing unit being operative to perform other reverse time synchronizations between the sending device and other non-target receiving devices in addition to the reverse time synchronization and determine the TE based on the other reverse time synchronizations and the reverse time synchronization;
- and
- schedule a gate time on the target receiving device based on the determined TE.
