Abstract: A method for transmitting and receiving a signal by a relay node in a wireless communication system is disclosed. More particularly, the method comprises the steps of: during communication on the basis of a first backhaul link synchronization and a first access link synchronization, transmitting, to a terminal, information about change initiation to a second backhaul link synchronization; configuring a frame synchronization from the first backhaul link synchronization; and in order to configure to the terminal a second access link synchronization determined on the basis of the second backhaul link synchronization, transmitting a synchronization signal to the terminal.
