Abstract
An apparatus and method for supporting a different system in a broadband wireless communication system using a multi-hop relay scheme are provided. A DownLink/UpLink (DL/UL) frame of a Base Station (BS) includes a legacy access zone for communicating with a legacy Mobile Station (MS), a relay zone for communicating with a legacy Relay Station (RS), and a new zone for communicating with a new MS. A DL/UL frame of an RS includes a legacy access zone for communicating with a legacy MS and a legacy relay zone for communicating with a new BS by legacy standards.
