Apparatus and method for allocating resources in a wireless communication system and performs communication

The present invention discloses a method for allocating resources in a wireless communication system for performing communication with the terminal using the frequency resource. The method of the present invention to distinguish between the subcarrier set having a sub-carrier of a series of a predetermined number of subcarriers, and generates a reference resource index table mapping the consecutive indexes the distance between sub-carriers in the sub-carrier set to be the maximum the resource determines the amount of resources to transmit the downlink according to the procedure and the reference resource processes and the data channel conditions to transmit to each terminal to generate a resource index table using the unique information of the respective base stations from the index table, and in the index table it includes the step of allocating a resource to the terminal by using the index value. Frequency resource, resource allocation, diversity gain.
