Method and apparatus for allocating frequency resources in a wireless communication system supporting frequency division multiplexing

摘要

A method for allocating frequency resources to be used for multiple terminals in a Frequency Division Multiplexing (FDM) wireless communication system. The method includes performing at a first transmission time a process of hierarchizing a series of resource units constituting a service frequency band in a plurality of levels, and hierarchically dividing the series of resource units into blocks including at least one consecutive resource unit in each of the levels, and allocating some of the hierarchically divided blocks as frequency resources for each of the terminals; and performing, at a second transmission time, a process of hierarchically hopping the blocks allocated as the frequency resources for each of the terminals so that the blocks each have a different frequency band from a frequency band used at the first transmission time, and allocating the hopped blocks as frequency resources for each of the terminals.
