Abstract: 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.

Abstract: A sequence generation method for allowing a reception end to effectively detect a sequence used for a specific channel of an OFDM communication system, and a signal transmission/reception method using the same are disclosed. During the sequence generation, an index is selected from among the index set having the conjugate symmetry property between indexes, and a specific part corresponding to the frequency “0” is omitted from a transmitted signal. In addition, a reception end can calculate a cross-correlation value between a received (Rx) signal and each sequence using only one cross-correlation calculation based on the conjugate symmetry property.
