Abstract
Methods of controlling the power levels of transmitted signals in telecommunication systems are described. A user may be assigned a plurality of radio bearers associated with a plurality of physical channels for communicating with a radiocommunication system. A fast power control loop monitors a reference channel and adjusts transmit power in accordance with an SIR target value. A plurality of slow power control loops adjust the SIR target value and also provide offset transmit power values associated with each physical channel to adapt the transmit powers in accordance with varying quality requirements between radio bearers.
