Abstract:
A method for use in a cellular, FFT based multi-carrier communications system comprising N subcarriers, for allocating a set P of sub-carriers to be reserved for potential use as carriers of specific information. A number M indicating the number of sub-carriers to be allocated to a set P of sub-carriers, such that L=N/M is an integer. At least two subcarriers of the set P={(n0+m*L) mod N : 0≦m
