METHOD AND APPARATUS FOR TIME SYNCHRONIZATION BETWEEN NODES IN WIRELESS NETWORK

摘要

The present invention provides a method for synchronizing a reception point of a first node in a wireless network. The synchronization method comprises the following steps of: receiving signals from a plurality of second nodes at a first point, wherein the second nodes are adjacent to the first node; excluding at least one node among the second nodes when a reception point difference between the signals from the second nodes is greater than the length of cyclic prefix of one symbol; setting an initial value of a fast Fourier transform (FFT) start point using a reception point of a signal transmitted by at least one node among the remaining second nodes which have not been excluded in the excluding step; requesting the excluded second node in the excluding step to change a signal transmission point; and updating the FFT start point at a second point by receiving signals from the second node which has been excluded and requested to change the signal transmission point and the remaining second nodes which have not been excluded.;COPYRIGHT KIPO 2015
