Patent ID: 8462682

Claim:
A method in a first node of adjusting correctness target values for controlling the power of radio signals sent to the first node by a second node over at least a control channel and a data channel, the control channel controlling the data channel, the method comprising: receiving a first signal on the control channel; obtaining a first quality value of the control channel; establishing a first difference as the difference between the first quality value and a first quality target value of the control channel; adjusting a first correctness target value based on said first difference for controlling the power of radio signals sent over the control channel; receiving a second signal over the data channel; establishing that the second signal has been correctly received; obtaining a number of transmission attempts taken to correctly receive the second signal; comparing the number of transmission attempts with a transmission attempts threshold value; establishing a second difference as the difference between the number of transmission attempts and a second transmission attempts target value of the data channel; without simultaneously adjusting the first correctness target value, adjusting a second correctness target value based on said second difference for controlling the power of radio signals sent over the data channel.
