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.

A method for DownLink (DL) frame communication in a multi-hop relay wireless communication system supporting different standards, the method comprising:
- transmitting, by a Base Station (BS), DL data to at least one legacy Mobile Station (MS) having a direct link through a BS legacy access zone within a DL frame for the BS;
- transmitting, by a legacy Relay Station (RS), DL data to at least one legacy MS having a relay link through a first RS access zone within a DL frame for the legacy RS, wherein the legacy RS supports only a legacy standard;
- transmitting, by the BS, DL data to the legacy RS through a BS legacy relay zone within the DL frame for the BS;
- receiving, by the legacy RS, the DL data from the BS through a RS relay zone within the DL frame for the legacy RS;
- and
- transmitting, by the BS, DL data to only at least one new MS having the direct link through a BS new zone within the DL frame for the BS,
- wherein the BS legacy access zone and the first RS access zone are allocated in identical frequency-time resources,
- wherein the BS new zone and a second RS access zone are allocated in identical frequency-time resources, and
- wherein the DL frame includes a first zone and a second zone, the first zone including the BS legacy access zone, the first RS access zone, the BS legacy relay zone, the RS relay zone, and the second zone including the BS new zone and the second RS access zone.
