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 transmitting a synchronization signal by a transmitting side device to a receiving side device in a wireless access system. The method includes generating a concatenated code sequence in a frequency domain by concatenating a first code sequence having a first index (M1) and a second code sequence having a second index (M2). Each of the first code sequence and the second code sequence is obtained by cyclic shifting a code sequence. The concatenated code sequence is mapped to subcarriers for transmitting the synchronization signal via a secondary synchronization channel (S-SCH). The method further includes transforming the concatenated code sequence into a time domain signal; and transmitting the time domain signal to the receiving side device as the synchronization signal. The concatenated code sequence indicates a cell group identity (ID).

Abstract: A method is provided for transmitting a demodulation reference signal (DMRS) by a user equipment (UE) in a wireless communication system. The UE receives a cyclic shift field in an uplink scheduling assignment from a base station, allocates a first cyclic shift value of a first DMRS for a first layer and a second cyclic shift value of a second DMRS for a second layer, based on the cyclic shift field, and transmits the first DMRS and the second DMRS to the base station.
