The system for allocating the radio resources includes a frequency allocating network element (204) for allocating radio frequency bands (306, 308) to at least two radio cells (214, 216) located within a reuse distance (238) from each other, at least one overlap region (310) being formed between the radio frequency bands (306, 308), the at least one overlap region (310) being reserved for a simultaneous use in the same transmission direction of the at least two radio cells (214, 216). The invention provides a frequency reuse capability for radio cells located within a reuse distance from each other.

    • A transmitter clips a transmission signal before transmis- sion in order to reduce the strength of at least one peak of the transmission signal exceeding a predetermined threshold. The transmitter comprises a clipper comprises a minimizer (400), a filter (402) and an adder (404). The minimizer (400) minimizes of a cost function with respect to an optimisation signal, the cost function having weighted terms as a function of the optimisation signal, the terms relating to an effective modulation distortion and an effective overshoot exceeding the predetermined threshold. The filter (402) forms a clipping signal by filtering the optimisation signal formed as a result of the minimization according to the spectrum emission mask requirements of the radio system. The adder (404) subtracts the clipping signal from the transmission signal.

    • The specification and drawings present a new method, system, apparatus and software product for carrier frequency shifting in mobile communication systems, e.g., for eliminating or reducing interference, e.g., for a communication between a mobile station and a network element. The communication between the mobile station and the network element may be performed within a GSM/EDGE radio access network. A signal (e.g., a DSR or MDSR carrier) and at least one further signal (e.g., a speech carrier) are identified, wherein bandwidths of the signal and of the at least one further signal overlap. Then, a frequency shift for said signal may be determined according to a predetermined criterion and a carrier frequency of the signal may be shifted by the determined frequency shift, e.g., for eliminating or reducing the interference.
