Patent ID: 7885230

Claim:
A method for distributively mapping consecutively allocated virtual resource blocks to physical resource blocks in a wireless mobile communication system, the method comprising: interleaving, using a block interleaver, indexes of the virtual resource blocks; sequentially mapping the interleaved indexes to indexes of physical resource blocks on a first slot of a subframe; cyclically shifting the interleaved indexes with a predetermined gap; and sequentially mapping the cyclically-shifted indexes to indexes of physical resource blocks on a second slot of the subframe, wherein the first slot and the second slot constitute the subframe, wherein resource block groups (RBGs), which are composed of the physical resource blocks, are indicated by a bitmap, each of the RBGs is indicated by a bit of the bitmap, and each of the RBGs is composed of a number, M RBG , of the physical resource blocks that are consecutive, and wherein a predetermined number of the subframes constitute a frame, and the gap is a multiple of a square of M RBG .
