Abstract:
1. A method of mapping an uplink physical resource to an uplink logical resource in a wireless communication system, the method comprising: rearranging, by a transmitter, physical resources of an uplink physical frequency band using a specific permutation rule; dividing, by the transmitter, the rearranged physical resources into at least one frequency partition for at least one sector, wherein each of the at least one frequency partition includes a localized region and a distributed region, and the localized region and the distributed region are configured based on a number of frequency-domain basic units in a frequency domain; and mapping, by the transmitter, each of the at least one frequency partition into uplink logical resource units including uplink localized logical resource units and uplink distributed logical resource units, wherein the localized region in each of the at least one frequency partition is directly mapped into the uplink localized logical resource units and the distributed region in each of the at least one frequency partition is mapped into the uplink distributed logical resource units by subcarrier permutating on data subcarriers of the distributed region.
