Abstract:
A method for controlling the transmission power of a transmission from a mobile station to a base station on a first channel in a telecommunication system, wherein said first channel is shared by a plurality of mobile stations, said method comprising the steps of:(a) measuring a first parameter value on a second channel, the second channel having a predetermined power relationship with the first channel, and determining a first power value from said first parameter at the base station; (b) determining a second power value from at least a second parameter, said second parameter indicating a desired performance level for the transmission on the first channel; (c) comparing said first power value and said second power value, and determining a third parameter value based on said predetermined power relationship and said comparison between said first power value and said second power value at the base station, said third parameter value for controlling transmission power of the mobile station in said first channel; and (d) transmitting a message from the base station to the mobile station on a third channel, formed of a common control channel, said message including said third parameter value, said common control channel used by the base station upon which to transmit to said plurality of mobile stations.
