Abstract  Abstract

Method and transmitting party device for transmitting a reference signal sequence using a Zadoff-Chu (ZC) sequence the method comprising: acquiring a base sequence among a plurality of base sequences wherein the plurality of base sequences are divided into groups wherein each of the plurality of base sequences is generated by a cyclic extension of a q-th root ZC sequence wherein each of the plurality of groups comprises base sequences having variable lengths wherein a sequence group index u is determined based on a cell of the transmitting party and wherein the q is determined by using the u and a length of the q-th root ZC sequence; applying a cyclic shift to the acquired base sequence to generate the reference signal sequence; and transmitting the reference signal sequence to a receiving party.

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.
