Abstract: A wireless communication method for efficiently managing a bandwidth request of a terminal and an allocation procedure and a system thereof are provided to operate an RS system in two modes in consideration of a case that an MS directly transmits a BR code to an MR-BS, thereby improving system performance while satisfying existing standards. It is monitored whether an uplink map information element corresponding to a BR(Bandwidth Request) code of an MS(Mobile Station) is received from an MR(Mobile Relay)-BS(Base Station)(S402). The RS monitors an uplink burst having a bandwidth that the MS requests is transmitted from the MR-BS based on the uplink map information element. Data that the MS transmits is relayed to a band allocated by the uplink burst from the MR-BS.
