A method of adjusting a signal quality target at a transceiver of a CDMA radio communication network. The adjustment of the signal quality target ensures that a predefined frame quality target is reached in power control procedure. According to the invention, the method consists in computing for a received frame, a frame quality indicator depending on signal quality indicators measured at slot level in the received frame. The method further comprises a step of adjusting the signal quality target according to the difference between the frame quality indicator and the predefined frame quality target.
