Abstract: PURPOSE: A wireless resource allocating device in a relay based mobile communication network and a method thereof are provided to enable a base station and a relay to perform scheduling with only channel state information about a connected user terminal which is connected to the base station and the relay, thereby eliminating a need of the base station and the relay which obtains CQI reports about other user terminals which are not connected. CONSTITUTION: A base station receives a CQI(Channel Quality Indicator) report about a first relay zone from a base station terminal in a second relay zone(S801). The base station receives a CQI report about a first access zone from the base station terminal in a second access zone. At the same time, the base station schedules a third relay zone(S802). The base station transmits data to the base station terminal by scheduling a third relay zone. At the same time, the base station schedules a third access zone(S803). The base station transmits data to the base station terminal in the third access zone(S804).
