Patent ID: 8130714

Claim:
A method for transmitting a signal by a mobile station in a wireless communication system, the method comprising: configuring distributed resources across a plurality of contiguous subframes; and transmitting the signal through the distributed resources to a base station, the distributed resources are permutated in each subframe and permutation pattern is different for each subframe: and wherein the permutation pattern is obtained by using the following equation, Tile( s,n,t )= L DRU,FPi ×n+g (PermSeq( ), s,n,t ) where Tile(s,n,t) denotes a tile index of an n th tile in an s th Distributed Logical Resource Unit (DLRU) of a t th subframe, L DRU,FPi denotes a number of Distributed Resource Units (DRUs) in an i th frequency partition, and g(PermSeq( ), s,n,t) denotes a function which uses PermSeq( ), s, n and t as parameters denoting a permutation sequence of length L DRU,FPi , and UL_PermBase being set to a value related to cell ID.
