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. As a synchronization method for an electronic device performing wireless communication with other electronic devices, the method may include: checking, when two or more reference synchronization signals are received within a preset period, whether the received reference synchronization signals are synchronized; determining, when the received reference synchronization signals are not synchronized, to operate as a device sending a reference synchronization signal of a class lower than or equal to that of the lowest class reference synchronization signal among the received reference synchronization signals; sending a reference synchronization signal at a preset time in a synchronization frame designed to preserve temporal orthogonality between classes; and performing synchronization between reference synchronization signals in cooperation with different devices having sent reference synchronization signals.
