Patent ID: 7729377

Claim:
A method for distributively mapping virtual resource blocks (VRBs) to physical resource blocks (PRBs) in a wireless mobile communication system, the method comprising: interleaving by a base station, indexes of the VRBs, of a downlink data packet using a block interleaver; mapping the interleaved indexes onto a first slot and a second slot of a subframe of a downlink data packet with a gap for distribution; and transmitting the mapped data packet to a user equipment, wherein an index o 1,d of one of the PRBs on the first slot mapped to a given index d of one of the VRBs is set to p 1,d +N offset if a temporary index p 1,d of one of the PRBs on the first slot mapped to the index d by the block interleaver is larger than N DVRB /2, and an index o 2,d of the one of the PRBs on the second slot mapped to the index d is set to p 2,d +N offset if a temporary index p 2,d of one of the PRBs on the second slot mapped to the index d by the block interleaver is larger than N DVRB /2, wherein N DVRB is a number of the VRBs and N offset is a predetermined integer, and wherein d has an integer value in a range from 0 to N DVRB −1, and p 1,d , p 2,d , o 1,d , and o 2,d have an integer value in a range from 0 to N PRB −1, N PRB being a number of the PRBs in the wireless mobile communication system, wherein the wireless mobile communication system supports a resource allocation scheme.
