A method in a user equipment (28, 30) of determining that an uplink (UL) to a communication node (16, 18, 20, 22) is out of synchronization (OoS). According to the method, newer transmit power control (TPC) commands are compared to older TPC commands received from the node. If an output signal generated from the comparing step exceeds a threshold, a signal-to-interference ratio (SIR) for a downlink (DL) from the node is measured. Furthermore, it is determined, based on the measured SIR, whether the node is following TPC commands sent to the node in the UL. If the node is not following the TPC commands, OoS is determined. A computer program product for performing the method, a computer readable medium having stored thereon a computer program product for performing the method, and a user equipment for performing the method are also disclosed. |
