Claim Text:
1. A method of generating a reference signal for use in a communication system in which for reference signal generation multiple base sequences are defined, the method comprising; generating a first reference signal sequence from a first base sequence; generating a second reference signal sequence from a second base sequence; and generating the reference signal comprising the first reference signal sequence and the second reference signal sequence, wherein generating the first reference signal sequence and the second reference signal sequence comprises applying at least one of a sequence group hopping pattern and a sequence-within-group hopping pattern to determine the first base sequence and the second base sequence respectively, wherein the first reference signal sequence occupies a first spectral fragment of the reference signal and the second reference signal sequence occupies a second spectral fragment of the reference signal, the second spectral fragment and the first spectral fragment are spectrally located immediately adjacent to one another and do not spectrally overlap.
