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: Method for generating reference signal sequence using grouping is explained. In this method, base sequences are grouped such that each group contains at least one base sequence of each length, so UE(s) can use various length sequences as a reference signal. And in this method, inter cell interference caused by using various length sequence as a reference signal sequence can be minimized by grouping sequences having the high cross correlation relation.
