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.

Abstract: A method for generating an iterative sequence and a signal transmission method using the same are disclosed. As the cell size or the distance between a user equipment (UE) and a Node-B increases, the CP is repeated at least one time while the iterative sequence is generated, the CP length and the ZCZ length are adjusted, so that the sequence timing point can be easily detected, orthogonality between sequences is maintained, and the sequences can be clearly distinguished from each other.
