Patent ID: 8295389

Claim:
A method of transmitting signals from a transmitter to a receiver using a Zadoff-Chu sequence, the method comprising: mapping a sequence used for a synchronization signal to a plurality of frequency resource elements to provide a frequency-domain-mapped sequence, wherein the sequence is generated from the Zadoff-Chu sequence in a frequency domain according to a predetermined root index; converting the frequency-domain-mapped sequence into a time-domain transmission signal; and transmitting the time-domain transmission signal to the receiver, wherein: the time-domain transmission signal is transmitted by omitting a specific component from the Zadoff-Chu sequence corresponding to a center of the Zadoff-Chu sequence; a length of the Zadoff-Chu sequence is 63; first 31 constituent components of the Zadoff-Chu sequence are continuously mapped to a plurality of frequency resource elements corresponding to frequency resource element indices within a range of “−31” to “−1”; and last 31 constituent components of the Zadoff-Chu sequence are continuously mapped to a plurality of frequency resource elements corresponding to frequency resource element indices within a range of “1” to “31”.
