The present invention is directed to a method for predicting a bit rate provided by an enhanced data channel in a future radio channel, once the future radio channel is added to an ordinary data channel in an operational radio channel. It is assumed that the bit-rate provided by the enhanced data channel is indicated by the ratio (A), wherein E is the enhanced data channel power offset, E is the ordinary control channel power offset after a future addition and k1 is a constant. The method comprises with respect to the operational radio channel the steps of obtaining a first transmit power P1, a first quality target Q1, the power offset O for an ordinary control channel and the power offset O for the ordinary data channel. In addition, the method comprises with respect to the future radio channel the steps of obtaining a second transmit power P2 and a second quality target Q2. The ratio (A) indicating said bit-rate is then obtained by the step of using the expression (B) wherein k2 and k3 are predetermined constants.
