Patent ID: 8018966

Claim:
A method for receiving a downlink data packet in a wireless mobile communication system supporting a resource allocation scheme distributively mapping virtual resource blocks (VRBs) to physical resource blocks (PRBs), 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 VRBs of the downlink data packet are interleaved by a base station using a block interleaver, wherein the interleaved indexes are mapped onto N s slots of a frame of the downlink data packet with a gap for distribution in each of the N s slots to generate a mapped downlink data packet, wherein N s denotes a number of slots included in the frame, wherein the mapped downlink data packet is transmitted from the base station to the user equipment, wherein an index of one of the PRBs on each of N s slots mapped to an index of one of the VRBs is determined by using N gap and N DVRB , and wherein N gap is a value of the gap and N DVRB is a number of the VRBs.
