Abstract: A method for establishing a cyclic shift sequence to provide against the frequency offset is disclosed. The method calculates a distance between a channel response position of the sequence and an alias channel response position caused by a frequency offset, calculates the number of cyclic shifts per group according to the calculated distance, and establishes the cyclic shift (CS)-applying interval. This method easily establishes a cyclic shift (CS) interval at a specific location having no overlapping by considering a channel response of a reception (Rx) sequence and an alias location of this reception (Rx) sequence, although a reception (Rx) signal is shifted by a channel delay spreading or a propagation delay irrespective of categories of a domain generating a sequence, so that it can greatly reduce the number of the detection errors and the false alarm rate. And, if a sequence of the cyclic shift (CS) is allocated to a cell having a frequency offset of more than a predetermined level, the present invention can minimize the influence of a frequency offset on a high-mobility cell.

Abstract: A method for transmitting a demodulation reference signal (DMRS) for a physical uplink shared channel (PUSCH), by a user equipment (UE), in a wireless communication system. The UE generates first, second, and third DMRS sequences, which are associated with first, second, and third layers respectively, by applying first, second, and third cyclic shifts to the first, second, and third DMRS sequences respectively. The UE transmits the first, second, and third DMRS sequences to a base station, wherein the first, second, and third cyclic shifts are determined based on first, second, and third cyclic shift values respectively. The first and second cyclic shift values are separated from each other by a maximum separation value, which is determined based on a total number of cyclic shifts. The third cyclic shift value is determined by increasing cyclically by a median separation value between the first and second cyclic shift values.

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 is provided 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. The Node-B transmits a random access procedure configuration including a basic sequence index related with a random access channel and zero correlation zone (ZCZ) configuration. The Node-B receives a random access preamble corresponding to the random access procedure configuration from the UE over the random access channel. A length of a cyclic part and a length of a sequence part of the random access preamble are differently given based on the random access procedure configuration. The random access preamble is generated from Constant Amplitude Zero Auto-Correlation (CAZAC) sequences based on the basic sequence index by applying a length of a cyclic shift according to the ZCZ configuration.
