Method of mapping physical resource to logical resource in wireless communication system

A transmitter in a wireless communication system, the transmitter comprising:

• a radio frequency (RF) unit configured to transmit or receive a radio signal;
• and
• a processor configured to:
• rearrange physical resource units using a specific permutation rule, wherein each physical resource unit is a basic physical unit for resource allocation that comprises a plurality of consecutive subcarriers by a plurality of consecutive orthogonal frequency domain multiple access (OFDMA) symbols;
• allocate the rearranged physical resource units into one or more frequency partition, wherein each frequency partition includes at least one of a localized region and a distributed region;
• and
• map each frequency partition into logical resource units including at least one of distributed logical resource units and localized logical resource units,
• wherein the distributed region in each frequency partition is mapped into the distributed logical resource units by subcarrier permuting on data subcarriers of the distributed region, and
• wherein the localized region in each frequency partition is directly mapped into the localized logical resource units.
