Abstract
A method and system for relaying data in a mobile communication system are provided, in which a Relay Station (RS) configures a routing table using Link Quality Information (LQI) exchanged among Relay Stations (RSs) in a cell, determines a relay path referring to the routing table, measures the quality of a signal received from an Mobile Station (MS), determines whether to relay data received from the MS by comparing the measured signal quality with at least one of information regarding a data rate of the MS and a reference threshold, transmits a relay request message to a Base Station (BS), if the RS determines to relay the data received from the MS, updates the relay path, upon receipt of a relay response message accepting the relay request and broadcasting information from the BS, and relays the data received from the MS to the BS in the updated relay path.
