Document Type and Number:
WIPO Patent Application WO/2015/046925
Kind Code:
A1
Abstract:
The present invention relates to a method and apparatus for synchronization between electronic devices, and more particularly, to a synchronization method and apparatus for wireless communication between electronic devices. A method, which is a synchronization method in an electronic device for wireless communication with other electronic devices according to an embodiment of the present invention, comprises the steps of: when two or more reference sync signals are received within a predetermined period, checking whether the received sync signals have been synchronized; when the reference sync signals have not been synchronized, selecting a terminal for transmitting a reference sync signal which has the lowest rating or below among the received reference sync signals; when a terminal is selected as the reference sync signal transmission terminal, generating and transmitting a reference sync signal at a predetermined time point so as to have temporal orthogonality among ratings within a sync frame; and synchronizing the reference sync signal with the other electronic devices which transmit the reference sync signal.
