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

摘要

A method of mapping a physical resource to a logical resource in a wireless communication system is described. The method includes dividing a physical frequency band into at least one frequency partition. Each frequency partition is divided into a localized region and a distributed region in a frequency domain. The method further includes mapping the at least one frequency partition into at least one logical resource unit. The localized region is directly mapped into the logical resource unit and the distributed region is mapped into the logical resource unit after rearranging subcarriers within the distributed region.

1. A method of mapping, by a transmitter, a physical resource to a logical resource in a wireless communication system, the method comprising:
rearranging 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; allocating 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 mapping 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.
