Abstract
A method for power control in an enhanced uplink telecommunication system is disclosed. The power for an uplink DPCCH in a first E-DCH is controlled by a base station. The base station and a user calculate power for an E-DPDCH in the first E-DCH based on a power offset configuration and absolute grant provided by the base station. The user terminal transmits the uplink data traffic on the first E-DCH with the controlled DPCCH power and the calculated E-DPDCH power. When the base station and the user terminal detect that the E-DPDCH absolute grant is different from a grant threshold, the base station changes a SIR target value. The first base station and the first user terminal compensate the change by recalculating the E-DPDCH power, reflecting both the changed DPCCH power resulting from the changed SIR target value and the improvement due to optimized channel estimation.
