Abstract

The present invention provides a device and method for transmitting a relay synchronization signal on an LTE-A system based on orthogonal frequency division having a multi-hop relay. In one example of the present invention, the device for transmitting a relay synchronization signal employs a synchronization signal for synchronization between a relay and a base station, and for synchronising one relay and a lower relay, and also for synchronization with a terminal for the purpose of having one relay monitor a neighbouring base station or relay; the synchronization signal being employed in such a way as to generate a relay synchronization signal having low correlation properties and having the same PAPR characteristics as the synchronization signal, and also to generate a frame comprising a relay synchronization signal.
