METHOD AND APPARATUS FOR TRANSMITTING OR DETECTING A PRIMARY SYNCHRONIZATION SIGNAL

摘要

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.

1. A method of detecting a sequence used in a primary synchronization signal by a receiver in a mobile communication system, the method comprising:
receiving the primary synchronization signal from a transmitter; and detecting the sequence used in the received primary synchronization signal, wherein the sequence used in the primary synchronization signal corresponds to a sequence having an even number length and that is mapped on a frequency domain such that one half of the sequence is mapped before a DC frequency and the other half of the sequence is mapped after the DC frequency, and wherein the sequence mapped on the frequency domain is generated by using Zadoff-Chu sequence having an odd number length.
