Method and system for performing time synchronization between nodes in wireless communication system
A method is provided for synchronizing time between nodes in a wireless communication system. A reference node transmits a first packet to a correspondent node. Upon receiving the first packet, the correspondent node transmits a second packet with a reception time of the first packet recorded therein, to the reference node. Upon receiving the second packet, the reference node calculates a forward delay time using a transmission time and the reception time of the first packet. The correspondent node receives a third packet with the forward delay time from the reference node, and calculates a reverse delay time. The correspondent node calculates an offset value for the synchronization using the forward delay time and the reverse delay time.
