Abstract: A method for performing a random access procedure by a Node-B with a specific user equipment (UE) within a cell in which a plurality of UEs are located together. System information is transmitted for at least one of a basic sequence index and a length of a zero correlation zone (ZCZ) to the specific UE. A preamble sequence is received from the specific UE over a random access channel. The preamble sequence is generated from Constant Amplitude Zero Auto-Correlation (CAZAC) sequences distinguishable by at least one of the basic sequence index and a length of a Cyclic Shift (CS) applied to the preamble sequence. The length of the CS applied to the preamble sequence is given by one among a plurality of application lengths determined based on the length of the ZCZ. A number of the plurality of lengths are differently given based on a type of the specific UE.

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.
