Abstract: A method for efficiently scheduling virtual resource blocks to physical resource blocks is disclosed. In a wireless mobile communication system, for distributed mapping of consecutively allocated virtual resource blocks to physical resource blocks, when nulls are inserted into a block interleaver used for the mapping, they are uniformly distributed to ND divided groups of the block interleaver, which are equal in number to the number (ND) of physical resource blocks to which one virtual resource block is mapped.
