A method of communicating signals between a transmitter and a receiver in a mobile communication system, and the transmitter and the receiver for the same are disclosed. According to one embodiment, a method of transmitting signals by a transmitter in a mobile communication system includes: mapping, by the transmitter, a sequence generated by using a Zadoff-Chu sequence having a root index to frequency domain indexes; and transmitting, by the transmitter, the mapped sequence. The root index is selected from a predetermined index set consisting of three indexes. The three indexes include a first index and a second index. A sum of the first index and the second index corresponds to a length of the Zadoff-Chu sequence.
