Method and a device for adjusting the transmission power of signals transferred by plural mobile terminals

A method for adjusting transmission power, in a wireless cellular telecommunication network, of signals transferred by plural mobile terminals through a wireless interface, the mobile terminals being served by at least one base station or by home base stations, the home base stations being located in a cell of the at least one base station, the method comprising:

• obtaining path gains between the mobile terminals and the at least one base station and path gains between the mobile terminals and at least one home base station, and/or noise measured at the at least one base station and/or at the home base stations;
• determining statistics from the obtained path gains and/or noise;
• obtaining at least one coefficient of a function according to at least a part of the statistics determined from the obtained path gains and/or noise;
• and
• transferring an information representative of the at least one obtained coefficient to the mobile terminals to enable the mobile terminals to transfer signals at a transmission power derived from information representative of the at least one obtained coefficient.
