Abstract:
A method to modify a current transmitted power distribution used by at least two base stations transmitting a signal to a mobile station on the macro-diversity principle, characterized in that said method comprises:iâ€”measuring, at said mobile station, a quantity related to the signal to interference ratio for the part of said signal transmitted by each base station; iiâ€”processing some values by weighting and summing said measured quantities, a set of weighting coefficients corresponding to one hypothetical transmitted power distribution supposed to have been used by said base stations in place of said current transmitted power distribution; iiiâ€”associating to each of said values, a value of a quality of service according to a known function; ivâ€”replacing said current transmitted power distribution by one of said hypothetical transmitted power distributions providing a better value of quality of service than said current transmitted power distribution.
