Abstract: A method of mapping a physical resource to a logical resource in a wireless communication system is provided. The method includes: dividing a physical frequency band into at least one frequency partition, wherein each frequency partition is divided into a localized region and a distributed region in a frequency domain; and mapping the at least one frequency partition into at least one logical resource unit, wherein 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.

Abstract: A method for transmitting and receiving signals using multi-band Radio Frequencies (RFs) is provided. The method performs channel coding on an information unit of a specific layer above a physical layer to produce a specific number of codewords and maps the generated specific number of codewords to a plurality of frequency allocation bands managed by one specific layer, and then transmits the mapped signal through each of the plurality of frequency allocation bands. Each of the plurality of frequency allocation bands managed by the one specific layer has a band size for allocation for a specific service according to a predetermined frequency policy. When the generated specific number of codewords is mapped to the plurality of frequency allocation bands, each of the specific number of codewords is mapped to at least one of the plurality of frequency allocation bands.

Abstract: An adaptive resource partitioning method includes: selecting a predefined pattern-based partitioning method or an informed map-based partitioning method according to the number of channels used for resource allocation, data characteristics, and a channel environment variation, if the predefined pattern scheme is selected, selecting any of predefined patterns, partitioning distributed and localized resource allocation areas according to the selected pattern, and transmitting a pattern index of the selected pattern to a terminal, and if the informed map scheme is selected, partitioning distributed and localized resource allocation areas according to an arbitrary pattern, and transmitting bitmap control information indicating information of the partitioned areas to the terminal.
