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.
Claims19
A method for providing an indication of a decoding problem, comprising:
- detecting a problem in decoding uplink physical control channels for a Dedicated Physical Control Channel (DPCCH) or an Enhanced Dedicated Physical Control Channel (E-DPCCH);
- sending a modified Up Link (UL) Dedicated Channel (DCH) frame having a spare field modified to indicate a Transport Format Combination Indicator (TFCI) decode failure;
- and
- in response to receiving the modified UL DCH frame, controlling an Up Link (UL) Outer-Loop Power Control (OLPC) to keep a signal-to-interference ratio (SIR) of the UL DPCCH within a predetermined range.
A non-transitory computer-readable medium containing instructions which, when executed, cause a wireless communications system to perform steps comprising:
- detecting a problem in decoding uplink physical control channels for a Dedicated Physical Control Channel (DPCCH) or an Enhanced Dedicated Physical Control Channel (E-DPCCH);
- sending a modified Up Link (UL) Dedicated Channel (DCH) frame having a spare field modified to indicate a Transport Format Combination Indicator (TFCI) decode failure;
- and
- in response to receiving the modified UL DCH frame, controlling an Up Link (UL) Outer-Loop Power Control (OLPC) to keep a signal-to-interference ratio (SIR) of the UL DPCCH within a predetermined range.
A system for providing an indication of a decoding problem, comprising:
- a User Equipment (UE);
- a base station in wireless communication with the UE;
- wherein a problem is detected by the UE in decoding uplink physical control channels for a Dedicated Physical Control Channel (DPCCH) or an Enhanced Dedicated Physical Control Channel (E-DPCCH);
- wherein, in response to the problem being detected, a modified Up Link (UL) Dedicated Channel (DCH) frame is sent by the UE to the base station, the frame having a spare field modified to indicate a Transport Format Combination Indicator (TFCI) decode failure;
- and
- wherein, in response to the base station 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.
