FIELD: radio engineering, communication.SUBSTANCE: invention relates to a method of transmitting/receiving downlink data in an orthogonal frequency-division multiplexing (OFDM) cellular packet data communication system. The method of transmitting downlink data using resource blocks in a base station comprises transmitting to user equipment downlink data mapped to physical resource blocks (PRB), wherein virtual resource block (VRB) indices are mapped to PRB indices for a first slot and a second slot of a subframe, and PRB indices for the second slot are shifted relative to the PRB indices for the first slot based a predetermined gap, wherein the predetermined shift is applied to the PRB index when the index of said PRB is equal to or greater than a predetermined threshold.EFFECT: providing efficient transmission of downlink data.22 cl, 33 dwg |
