Abstract: Systems, methods and computer programs are disclosed for providing an indication of a decoding problem in a wireless system. A problem is detected in decoding uplink physical control channels for a Dedicated Physical Control Channel (DPCCH) or an Enhanced Dedicated Physical Control Channel (E-DPCCH). A modified Up Link (UL) Dedicated Channel (DCH) frame having a spare field modified to indicate a Transport Format Combination Indicator (TFCI) decode failure is sent. In response to receiving the modified UL DCH frame, an Up Link (UL) Outer-Loop Power Control (OLPC) is controlled to keep a signal-to-interference ratio (SIR) of the UL DPCCH within a predetermined range.
