METHOD AND SYSTEM FOR TIME SYNCHRONIZATION AMONG NODES IN A WIRELESS COMMUNICATION SYSTEM

摘要

That in a wireless communication system, to a method and system for performing a synchronization between nodes, a method for in particular to synchronize the time between nodes in a wireless communication system, a reference node as a reference of the synchronization that is the target of the synchronization the process of transmitting a first packet to the destination node, and the step of the destination node receiving the first packet is transmitted to the second packet is received, the time of the first packet to the basic node records and the second packet a and process the said reference node to calculate a forward delay by using the transmission time and the reception time of the first packet received by the destination node receives the third packet containing the the forward delay relative to the reference node, the process, and the target node to calculate the reverse delay includes the step of calculating an offset value for the synchronization using the forward delay and the reverse delay. ; Wireless communication system, time synchronization, clock drift
