Patent ID: 8391912

Claim:
A method implemented by a prediction device for predicting a bit rate provided by an enhanced data channel in a future radio channel that will be added to an ordinary data channel in an operational radio channel, the bit-rate provided by the enhanced data channel indicated by the ratio E d k1 /E oc k1 , wherein E d is the enhanced data channel power offset, E oc is the ordinary control channel power offset after said addition, and k1 is a constant, the method comprising: obtaining for the operational radio channel a first transmit power P 1 , a first quality target Q 1 , an ordinary control channel power offset O c , and an ordinary data channel power offset O d , obtaining for the future radio channel a second transmit power P 2 and a second quality target Q 2 , and obtaining said ratio E d k1 /E oc k1 indicating said bit-rate using the expression ( P 2 · Q 1 P 1 · Q 2 ) · ( k ⁢ ⁢ 2 + O d k ⁢ ⁢ 1 O c K ⁢ ⁢ 1 ) - k ⁢ ⁢ 3 , wherein k2 and k3 are constants.
