PURPOSE: A wireless communication system is provided to improve the bandwidth practice efficiency rather than the state that one-hop is not discriminated from multi-hop bandwidth requests. CONSTITUTION: A bandwidth request method in a multi-hop wireless network includes at least one user terminal in wireless communication with a relay station, and a relay station is in communication with other nodes in the network. Therefore the user terminal can perform either single-hop communication with the relay station or multi-hop communication with one of the other nodes. The bandwidth request method comprises the steps of: assigning to the user terminal a specific signal for use in a bandwidth request pertaining to at least one of multi-hop and single hop communication, and notifying the user terminal of the specific signal; the user terminal transmitting a bandwidth request to the relay station and indicating a single hop or multi-hop communication by including or not including said specific signal in said bandwidth request; and the relay station processing said bandwidth request in accordance with the presence or absence of said specific signal.
