1. A method of communication between a user station and first and second base stations in which the user station is simultaneously in bi-directional wireless communication with said first and second base stations, including a data transmission step in which an uplink signal including user data for communication to another user via the base stations and base station data for communication to said first and second base stations is transmitted from said user station to said first and second base stations, said base station data in said uplink signal (including first items that are processed selectively by said first base station and second items that are processed selectively by said second base station, and a power control step in which the power of a first downlink signal transmitted by said first base station to said user station is controlled selectively as a function of said first items and the power of a second downlink signal transmitted by said second base station to said user station is controlled selectively as a function of said second items, first and second desired corrections to the transmission powers of said first and second downlink signals are calculated that as a function of the respective values of the received first and second downlink signals and interference thereto at said user station, of a desired relative value of the received first and second downlink signals at said user station, and of a target value for the total power of the received first and second downlink signals and interference thereto.
