Abstract:
A method and an apparatus for acquiring initial synchronization in a wireless communication system are provided. A relay station determines whether or not the initial synchronization is acquired, determines a start position of a frame using a peak of an autocorrelation signal detected based on a preamble and a relay-amble (R-amble) received from a base station in the case in which the initial synchronization is not acquired, and determines the start position of the frame using a peak of an autocorrelation signal detected based on the relay-amble received from the base station in the case in which the initial synchronization is acquired.
