Patent ID: 7242954

Claim:
A method for adjusting transmission power at a base station in a telecommunication network having a mobile terminal operatively connected to the base station, said method comprising measuring in the mobile terminal a strength of a communication signal in relation to interference in the signal; comparing in the mobile terminal the measured strength with a referenced strength, providing adjustment information based on said comparing so as to allow the base station to adjust the transmission power according to the provided information, wherein the provided information is indicative of one of a plurality of adjustment codes including more than two different adjustment codes, wherein a difference strength is provided in response to said comparing, and the provided information comprises: a first adjustment code indicative of a bit pattern of“00” if the measured strength is greater than the referenced strength, and the difference strength is greater than a first selected value; a second adjustment code indicative of a bit pattern of“01” if the measured strength is greater than the referenced strength, and the difference strength is smaller than a first selected value; a third adjustment code indicative of a bit pattern of “10” if the measured strength is smaller than the referenced strength, and the difference strength is smaller than a second selected value; and a fourth adjustment code indicative of a bit pattern of “11” if the measured strength is smaller than the referenced strength, and the difference strength is greater than a second selected value.
