Abstract:
1. A method for receiving a downlink data packet in a wireless mobile communication system supporting a resource allocation scheme distributively mapping virtual resource blocks to physical resource blocks, the method comprising: receiving, by a user equipment, downlink control information including resource block assignment information for the downlink data packet; and receiving, by the user equipment, the downlink data packet based on the downlink control information, wherein indexes of the virtual resource blocks of the downlink data packet are interleaved by a base station using a block interleaver, wherein the interleaved indexes are mapped onto each slot of a subframe of the downlink data packet with a gap for distribution by the base station, the subframe including a predetermined number (N) of slots, wherein the block interleaver includes ‘N’ regions and when nulls are inserted into the block interleaver, the nulls are distributed to the ‘N’ regions of the block interleaver, and wherein when the indexes of the virtual resource blocks are read out from the block interleaver, the nulls are ignored.
