Patent ID: 7634289

Claim:
A method for controlling transmission power on communication channels in a radiocommunication system comprising at least one base station designed to transmit, in successive transmission time intervals, blocks destined for radio terminals, on communication channels shared among the radio terminals, the shared communication channels comprising traffic channels and control channels associated with traffic channels, whereby at least some of the blocks transmitted by the base station produce positive or negative acknowledgements from the radio terminals, the method comprising the following steps in relation to a radio terminal which is capable of receiving blocks on at least one traffic channel and one control channel associated with said traffic channel, during a next corresponding transmission time interval for each channel: determining at least one quality indication relating to said traffic channel; determining at least one quantity relating to acknowledgements previously transmitted to the base station; and calculating a transmission power on at least one of the traffic channel or the control channel associated with said traffic channel, for said next corresponding transmission time interval, from said quality indication relating to the traffic channel and said quantity relating to acknowledgements previously transmitted to the base station.
