Abstract: A sequence generation method for allowing a reception end to effectively detect a sequence used for a specific channel of an OFDM communication system, and a signal transmission/reception method using the same are disclosed. During the sequence generation, an index is selected from among the index set having the conjugate symmetry property between indexes, and a specific part corresponding to the frequency “0” is omitted from a transmitted signal. In addition, a reception end can calculate a cross-correlation value between a received (Rx) signal and each sequence using only one cross-correlation calculation based on the conjugate symmetry property.

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.

Abstract: A method and apparatus for transmitting or detecting primary synchronization signal. The receiver receives primary synchronization signal from a transmitter, and detects the sequence used in the received primary synchronization signal by using three root indexes. Here, the primary synchronization signal is generated by using a Zadoff-Chu sequence having one of the three root indexes. The three root indexes comprise a first index and a second index, and a sum of the first index and the second index corresponds to the length of the Zadoff-Chu sequence.

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.
