Sequence generation procedure for detection and procedure for the transmission and reception of signals using the same

摘要

A method of transmitting signals to a receiver in a transmitter of a mobile communications system based on an orthogonal frequency division multiplexing scheme, the method comprising: mapping a sequence with frequency domain resource elements, in which the sequence is generated in the frequency domain from a specific CAZAC sequence according to one of the root indices selected in a set of root indices comprising a first and a second index, where the sum of the first and second index corresponds to the odd length of the specific CAZAC sequence; convert the sequence mapped with the frequency domain into a time domain transmission signal; and transmit the time domain transmission signal to the receiver.
