ABSTRACT:
A method of allocating a communication signal to multiple carrier frequencies in a multi carrier communication scheme is disclosed. The method involves a step of defining a pilot pattern (76), each pilot symbol of the pattern defining a cluster of carrier frequencies. Furthermore, it is estimated (78) which carrier frequencies are appropriate to fulfil a desired quality of service requirement as a function of spreading factors associated with the pilot patterns. A carrier frequency is selected (86, 92) which is appropriate to fulfil the desired quality of service requirement. Further carrier frequencies that are separated from the first selected carrier frequency by the spreading factor (88, 94) are allocated.
