<p>Provided are a method of relaying a data burst in a relay station (RS) of a multi-hop relay (MMR) system using a direct relay zone, and a system using the method. The RS requests a base station to assign the direct relay zone in a frame in which a demodulation and forwarding scheme that demodulates, and then modulates and transmits a data burst is applied, receives an acknowledgement to the request from the base station, and relays a data burst using the frame in which the direct relay zone is assigned. Accordingly, since a data burst can be relayed within one frame, relay latency can be reduced.</p> |
