ABSTRACT:
In a combined time-division multiple access and frequency-division multiple access multilayer cellular mobile radio network comprising macrocells and microcells, each macrocell being associated with at least one control frequency and at least one traffic frequency and each microcell being associated with at least one control frequency, a method of optimizing frequency use when adding any microcell base station defining a given microcell that is part of a coverage area of a given macrocell includes the step of allocating to said microcell a control frequency identical to a traffic frequency used in a macrocell immediately adjacent said given macrocell.
