METHOD AND SYSTEM FOR ACCURATE CLOCK SYNCHRONIZATION THROUGH INTERACTION BETWEEN COMMUNICATION LAYERS AND SUB-LAYERS FOR COMMUNICATION SYSTEMS |
摘要 |
Time synchronization in a wireless communication system comprises transmitting a synchronization frame from a transmitter to a receiver over a wireless communication medium. The synchronization frame includes a timestamp indicating the transmitter local time when a symbol at a predefined position of the synchronization frame is placed on the wireless communication medium for transmission. The synchronization frame is received at the receiver which determines a receiving time comprising the receiver local time when said symbol of the synchronization frame was received at the physical layer of the receiver. Time synchronizing is performed by determining a difference between said timestamp and said receiving time, and adjusting the receiver local time based on said difference to time synchronize the receiver with the transmitter. |
