Abstract
An apparatus and a method for processing a change of a preamble of a Relay Station (RS) are provided. An operating method of a Base Station (BS) includes providing a relay service via an RS, determining whether a preamble of the RS needs to change, when it is necessary to change the preamble of the RS, sending a preamble change command message to the RS and, when the preamble of the RS is changed, sending a preamble change notification message informing of the preamble change to at least one lower node of the RS.
